Getting approved for a mortgage is exciting, but the number a lender gives you isn’t the whole story. True affordability is about more than just a loan amount; it’s about your life. Stretching your budget to its limit can lead to becoming “house-poor,” where your home costs leave little room for savings, travel, or even a simple night out. The goal is to find a home that supports your lifestyle, not one that restricts it. We’ll explore how to determine a smart mortgage affordability percentage of income that protects your financial freedom and ensures your new home is a source of joy, not stress.
Key Takeaways
- Define affordability on your own terms: A lender’s pre-approval tells you the maximum you can borrow, not what you should. Your ideal budget should account for all housing costs—including taxes, insurance, and maintenance—while leaving plenty of room for savings, emergencies, and other life goals.
- Strengthen your financial profile for better loan terms: Your credit score and debt-to-income (DTI) ratio are the two most important factors lenders consider. Paying down existing debt and maintaining a strong credit history can help you secure a lower interest rate, saving you thousands over the life of your loan.
- Preparation is the key to a confident home search: Before you start looking at houses, take the time to review your spending, build your savings, and get pre-approved. This process transforms your budget from a guess into a concrete number, giving you true purchasing power and showing sellers you’re a serious buyer.
How Much of Your Income Should Go to Your Mortgage?
Figuring out “how much house can I afford?” is one of the first and biggest questions on any homebuyer’s mind. It’s about finding that sweet spot where you can buy a home you love without feeling financially squeezed every month. While every budget is personal, there are some trusted guidelines that lenders and financial experts use to determine a healthy mortgage payment. Think of these not as rigid rules, but as a reliable starting point to help you begin your search with confidence and protect your long-term financial well-being. Understanding these benchmarks will help you have a more productive conversation with your loan officer and set realistic expectations for your home search.
What is the 28% Rule?
The 28% rule is a standard guideline used to gauge mortgage affordability. In simple terms, it recommends that your total monthly housing payment should be no more than 28% of your gross monthly income—that’s your income before any taxes or deductions are taken out. Your total housing payment, often referred to as PITI, includes the four main components of your mortgage: principal, interest, property taxes, and homeowners insurance. By keeping your housing costs at or below this 28% threshold, you ensure there’s enough room in your budget for all of life’s other expenses, from groceries and utilities to savings and entertainment.
Why Lenders Start with This Guideline
While the 28% rule focuses solely on housing costs, lenders need to see the bigger picture of your financial obligations. That’s why they also look at your total monthly debt, which includes your potential mortgage payment plus any other recurring debts like car loans, student loans, or credit card payments. Ideally, this total should not exceed 36% of your gross monthly income. This is often called your debt-to-income (DTI) ratio.
While 36% is the target, some lenders might approve a loan even if your DTI is as high as 43%, especially if you have excellent credit and solid savings. However, it’s crucial to remember that what you can be approved for isn’t always what you should borrow. Choosing a lower payment gives you valuable breathing room for unexpected costs and helps you reach other financial goals. When you’re ready, you can apply now to get a clear picture of what numbers work for you.
Breaking Down the 28/36 Rule
When you start exploring mortgages, you’ll quickly hear about the 28/36 rule. Think of it as a classic guideline lenders use to get a quick read on what you can comfortably afford. It’s not a strict law, but it’s a solid starting point for both you and your lender to understand how a new mortgage payment fits into your overall financial picture. The rule is split into two parts: a front-end ratio that looks only at your housing costs and a back-end ratio that considers all of your debts. Understanding both pieces helps you see your finances from a lender’s perspective and set a realistic budget for your home search.
Your Front-End Ratio: Just Housing Costs
The first number, 28, refers to your front-end ratio, which focuses entirely on your potential housing expenses. The general guideline suggests that your total monthly mortgage payment—which includes the principal loan amount, interest, property taxes, and homeowners insurance (often called PITI)—should not exceed 28% of your gross monthly income. That’s your income before any taxes or deductions are taken out. For example, if you earn $6,000 a month before taxes, the 28% rule suggests your total housing payment shouldn’t be more than $1,680. This helps ensure you have enough cash left over for everything else life throws your way.
Your Back-End Ratio: The Full Picture of Your Debt
The second number, 36, is your back-end ratio, and it gives a more complete view of your financial obligations. This calculation takes your potential mortgage payment and adds it to all your other existing monthly debts. This includes car payments, student loans, credit card bills, and any other loans you might have. Lenders prefer this total to be no more than 36% of your gross monthly income. Using our previous example, if you earn $6,000 a month, your total debt payments (including your new mortgage) should ideally stay under $2,160. This ratio shows lenders how much of your income is already spoken for each month.
When Can You Go Above These Ratios?
While the 28/36 rule is a great benchmark, it’s not set in stone. Lenders know that every borrower’s situation is unique. In some cases, they may approve a loan even if your back-end ratio goes as high as 43%. This flexibility is often extended to borrowers with a strong financial profile, which might include a high credit score, a significant down payment, or substantial savings. However, it’s important to be cautious about stretching your budget this far. A higher ratio means a tighter monthly budget, leaving less room for savings or emergencies. Different loan programs have varying requirements, so it’s always best to discuss your specific numbers with a loan officer.
How Lenders Determine What You Can Afford
When you apply for a mortgage, lenders are essentially trying to answer one big question: How likely are you to pay back this loan on time? To figure that out, they look at your complete financial picture, not just your salary. Think of it as a financial health check-up. They’ll review a few key areas to gauge your ability to handle a monthly mortgage payment alongside your other expenses.
Understanding what they’re looking for puts you in the driver’s seat. When you know the main factors—your debt, your credit history, and your job stability—you can prepare your finances and walk into the application process with confidence. It helps you see your application from their perspective and highlights areas you might want to strengthen. Knowing where you stand is the first step toward finding the right loan program for your future home.
Your Debt-to-Income (DTI) Ratio
Your debt-to-income (DTI) ratio is one of the most important numbers lenders consider. In simple terms, it’s the percentage of your gross monthly income (what you make before taxes) that goes toward paying your recurring debts. This includes things like car payments, student loans, credit card bills, and your future mortgage payment. Lenders use this figure to see how much financial breathing room you have each month.
Ideally, lenders prefer your total monthly debt payments to be no more than 36% of your income. However, that’s not always a hard-and-fast rule. Depending on other factors like your credit score and down payment, some lenders might approve a DTI as high as 43%. Calculating your DTI ratio before you apply can give you a clear idea of where you stand.
How Your Credit Score Shapes Your Options
Think of your credit score as your financial report card. It tells lenders how reliably you’ve managed debt in the past. A higher score shows you have a strong history of paying your bills on time, which makes you a lower-risk borrower. This is where a good score really pays off: it can help you secure a lower interest rate on your mortgage.
Even a small difference in your interest rate can save you thousands of dollars over the life of your loan and result in a lower monthly payment. If your score isn’t where you’d like it to be, don’t worry. There are concrete steps you can take to improve your credit. Taking the time to build a stronger credit history is one of the smartest moves you can make before buying a home.
Why Your Employment History Matters
Beyond your income, lenders want to see stability. A steady employment history shows them that you have a reliable source of funds to cover your mortgage payments month after month. They aren’t just looking at what you earn now, but also at the consistency of your earnings over time. Typically, lenders like to see that you’ve been steadily employed with a consistent income for at least the past two years.
This doesn’t necessarily mean you need to have been at the same company for two years. It’s more about showing you haven’t had long, unexplained gaps in your employment. For self-employed individuals or those with variable income, lenders will usually look at an average over that two-year period. This history gives them the confidence that you’ll continue earning and be able to manage your payments long-term. When you’re ready, you can start your application with this information in hand.
The Risks of a House-Poor Life
Getting approved for a mortgage is exciting, but it’s easy to get carried away by that maximum loan amount. Lenders will tell you what you can borrow based on formulas, but that number doesn’t always reflect what you should borrow for a comfortable life. Stretching your budget to its absolute limit to get a bigger house can lead to a stressful situation known as being “house-poor.” This is when so much of your income goes toward your mortgage and housing costs that there’s little left for anything else. It’s a trap that can turn the joy of homeownership into a constant financial burden.
Being house-poor isn’t just about cutting back on lattes; it’s a persistent source of financial anxiety. It means every unexpected expense, from a car repair to a medical bill, becomes a major crisis. It can also mean putting other important financial goals, like saving for retirement or your kids’ education, on the back burner indefinitely. The key is to find a home that fits your life, not a home that your life has to shrink to fit into. By carefully considering your options and choosing from the right loan programs, you can ensure your home is a source of stability and happiness, not stress.
The Strain on Your Monthly Budget
When your mortgage payment takes up too much of your paycheck, the squeeze is felt immediately. As Bankrate notes, “Spending too much on your mortgage can leave you ‘house poor,’ meaning you struggle to pay for other important things or save money.” Suddenly, your monthly budget has no wiggle room. You might find yourself saying “no” to dinner with friends, postponing vacations, or feeling stressed at the grocery store checkout. This constant financial pressure can take a toll on your quality of life, turning your dream home into a source of daily worry instead of a place of comfort and security.
When Your Emergency Fund Can’t Grow
A healthy emergency fund is your financial safety net, there to catch you when life throws a curveball. But when your mortgage payment is maxed out, building that fund becomes nearly impossible. Even if a lender approves a high payment, it’s often wiser to choose a lower amount to give yourself some financial breathing room. Without that cushion, an unexpected job loss or a leaky roof can quickly spiral into high-interest credit card debt. A comfortable mortgage payment allows you to consistently set money aside, ensuring you’re prepared for whatever comes your way without risking your home.
Losing Flexibility for Life’s Changes
Life rarely stays the same. You might decide to change careers, start a family, or go back to school. A mortgage that’s too large can severely limit your ability to adapt to these changes. Just because you qualify for a certain loan amount doesn’t mean you should take the full sum. It’s crucial to plan for both expected and unexpected costs when you become a homeowner. When your budget is stretched thin, you lose the flexibility to pursue new opportunities or handle life’s transitions. Your home should support your life goals, not hold you back from them. Getting expert advice can help you find a number that works for your life today and tomorrow.
Costs to Plan for Beyond Your Mortgage Payment
Your mortgage payment is the headline act, but it’s not a solo performance. True home affordability means looking at the entire ensemble of costs that come with owning a property. Thinking about these expenses from the start helps you create a realistic budget and avoid the stress of being “house-poor,” where your home costs leave little room for anything else. When you’re planning your finances, be sure to account for these key expenses that go beyond your principal and interest payment. This holistic view is crucial for long-term financial health and truly enjoying your new home without constant money worries. At UDL Mortgage, we believe in empowering our clients with a complete picture, which is why our Elite Partner Program connects you with experts who can help you plan for every aspect of homeownership.
Property Taxes and Homeowners Insurance
It’s easy to forget about property taxes and homeowners insurance because they’re often rolled into your monthly mortgage payment. Your lender typically collects a portion of these costs each month and holds it in an escrow account, paying the bills on your behalf when they’re due. While this is convenient, it’s important to remember these are separate, significant expenses. Property taxes are set by your local government and can change over time, while homeowners insurance is required to protect your home against damage or disaster. Factoring these into your budget from day one is non-negotiable for responsible homeownership.
Maintenance, Repairs, and HOA Dues
Unlike renting, when you own a home, you’re the one responsible when the dishwasher stops working or the roof starts leaking. A great rule of thumb is to set aside about 1% of your home’s value each year specifically for maintenance and repairs. This creates a financial cushion so that unexpected expenses don’t become full-blown emergencies. If your new home is in a planned community or condo building, you’ll also likely have homeowners association (HOA) dues. These fees cover the upkeep of shared spaces and amenities and can vary significantly, so be sure to get the exact amount before you commit.
Utilities and Other Monthly Bills
Your monthly bills will likely look different as a homeowner. You’ll need to budget for all the essential utilities, including electricity, water, gas, internet, and trash collection. If you’re moving from a smaller apartment to a larger house, expect these costs to increase. It’s a smart idea to ask the seller for an estimate of their average monthly utility bills to get a more accurate picture. Don’t forget to also consider other potential services you might need, like landscaping, pest control, or a home security system. Planning for these ongoing expenses helps ensure your budget is built on solid ground.
Common Missteps in Gauging Affordability
Figuring out what you can truly afford is one of the most critical steps in the homebuying process. It’s easy to make a few common mistakes that can lead to financial stress later on. By being aware of these potential pitfalls, you can approach your budget with clarity and confidence, ensuring you find a home that fits comfortably into your life.
Forgetting Costs Beyond Principal and Interest
It’s easy to focus solely on the mortgage payment—the principal and interest—but that’s only part of the monthly cost. True homeownership involves other significant expenses like property taxes, homeowners insurance, and potential HOA fees. You also need to plan for home maintenance and repairs, because things will eventually need fixing or replacing. A good practice is to budget for these costs from the very beginning. Factoring in these additional expenses gives you a much more realistic picture of your monthly housing payment and helps you avoid feeling stretched thin once you have the keys.
Counting on Unreliable Income
When you’re calculating how much you can afford, it’s tempting to include every potential dollar, from a possible bonus to income from a side hustle. However, lenders prioritize a stable and predictable income. They typically want to see a consistent work history for at least the past two years to feel confident in your ability to make payments long-term. Basing your budget on income that isn’t guaranteed can put you in a precarious position if that money doesn’t come through. It’s always safer to build your budget around the income you know you can rely on every month.
Ignoring Your Future Financial Goals
Getting approved for a large loan can feel exciting, but it doesn’t mean you should borrow the maximum amount. A lender might approve you for a mortgage that technically fits within debt-to-income guidelines, but that could leave you with little room for anything else. Think about your other life goals. Do you want to save for retirement, travel, or invest? A mortgage that consumes too much of your income can sideline those dreams. Choosing a more conservative loan amount provides the financial flexibility to handle life’s surprises and continue working toward your other important goals without the strain of a burdensome house payment.
How to Figure Out Your True Budget
Affordability rules are a great starting point, but your true budget comes down to your unique financial picture. Moving from general guidelines to a concrete number requires a closer look at your income, spending, and savings. This process isn’t about limiting yourself; it’s about empowering yourself with the clarity you need to shop for a home confidently. By taking these next steps, you can find a mortgage payment that fits comfortably into your life, allowing you to enjoy your new home without financial stress. It’s about finding the perfect balance for your goals and lifestyle.
Use a Mortgage Calculator the Right Way
An online mortgage calculator is a fantastic tool for getting a quick snapshot of what you might be able to afford. You can plug in your income and expenses to get a ballpark figure in minutes. However, it’s important to remember that these calculators provide a rough estimate, not a guarantee. They can’t account for the specific interest rate you’ll qualify for or the nuances of your financial situation. For a more accurate assessment, you’ll want to consult with a mortgage lender who can provide insights tailored to you. Think of a calculator as your first draft—it gets the ideas on paper, but a conversation with an expert will help you refine the final story.
Do an Honest Budget Review
Now it’s time to get personal with your finances. Creating a detailed budget is the best way to understand your financial landscape and see where your money is really going. Pull together all your sources of income, then list out your existing debts (like student loans and car payments), monthly bills (utilities, phone), and regular spending (groceries, gas, entertainment). Don’t forget to include what you’re putting into savings. This comprehensive view will help you determine how much you can realistically allocate toward a mortgage each month. Be honest with yourself—this exercise is for your benefit and will help you find a home payment that doesn’t leave you feeling stretched thin.
Get Pre-Approved for a Realistic Number
Before you start scrolling through listings, getting pre-approved for a mortgage is a crucial step. This is where a lender evaluates your total income, your debt-to-income (DTI) ratio, your credit score, and your employment history to determine exactly how much they’re willing to lend you. A pre-approval gives you a firm price range for your house hunt and shows sellers that you’re a serious buyer. It moves you from guessing what you can afford to knowing your true purchasing power. When you’re ready to take this step, you can start your application to get a clear, realistic number to guide your search.
Are There Other Rules to Follow?
The 28/36 rule is a great starting point, but it’s not the only guideline out there. Think of these rules as different lenses to look through when figuring out your budget. Some are more conservative, while others offer more flexibility depending on your financial situation. The goal is to find the approach that gives you the most confidence and clarity. Exploring a few different methods can help you land on a number that feels right not just on paper, but for your actual life.
The 25% Rule for a More Conservative Budget
If the 28/36 rule feels a little too close for comfort, you might prefer the 25% rule. This approach suggests that your total monthly housing payment shouldn’t exceed 25% of your net income—that’s your take-home pay after taxes and other deductions are taken out. Using your net pay instead of your gross pay gives you a much more realistic picture of your day-to-day cash flow. This conservative strategy builds more breathing room into your budget, making it easier to handle unexpected expenses, save for the future, and still have money left over for the things you enjoy.
Factoring in Your Take-Home Pay
Lenders typically use your gross (pre-tax) income to calculate how much you can borrow, but your personal budget should always start with your take-home pay. This is the money that actually hits your bank account, and it’s what you’ll use to pay your mortgage, utilities, and groceries. Some general guidelines suggest housing costs should be around 25% to 30% of your income before taxes. You can use a mortgage affordability calculator to play with the numbers, but always compare the final estimate to your actual monthly take-home pay to see how it truly fits.
A Different Approach for High Earners
The standard rules don’t always apply in the same way to everyone, especially high earners. If you have a strong credit score, minimal debt, and healthy savings, a lender might approve you even if your total monthly debt is up to 43% of your gross income. While this offers more flexibility, it’s important to proceed with caution. Committing this much of your income to debt can leave your budget feeling tight. This is where having a conversation about your long-term goals and different loan programs can help you decide if stretching your budget is the right move for you.
How to Qualify for a Larger Loan (the Smart Way)
If you’re aiming for a larger loan, the goal isn’t just to get approved for the biggest number possible—it’s to strengthen your financial profile so you can comfortably afford the home you want. A higher loan amount can open up more possibilities in your home search, but getting there the right way means building a solid foundation. Lenders want to see a complete picture of your financial health, from your income and credit history to your savings. By focusing on a few key areas, you can present yourself as a reliable borrower and position yourself for the best possible loan terms. It’s about making smart, strategic moves that pay off when it’s time to secure your mortgage.
A High Credit Score and Low Debt
Your credit score and existing debt are two of the most significant factors lenders review. A higher credit score shows a history of responsible borrowing, which often qualifies you for a lower interest rate. That lower rate can save you thousands over the life of the loan and directly impacts how much you can borrow for the same monthly payment. At the same time, lenders look closely at your debt-to-income (DTI) ratio—the percentage of your monthly income that goes toward debt payments. If you have minimal debt from car loans, student loans, or credit cards, more of your income is free to cover a mortgage, making you a stronger candidate for a larger loan.
A Stable Job and a Healthy Down Payment
Lenders look for stability, and a consistent employment history is a great way to show it. Typically, they want to see at least two years of steady income, which gives them confidence in your ability to make mortgage payments long-term. Beyond your income, your down payment plays a huge role. A larger down payment reduces the total amount you need to borrow, which means lower monthly payments. It also demonstrates financial discipline. Plus, if you can put down 20% or more, you can often avoid paying for Private Mortgage Insurance (PMI), freeing up hundreds of dollars in your monthly budget. Some loan programs can even help with upfront costs, making it easier to allocate more of your savings toward the down payment.
Strong Cash Reserves
Having money in the bank after you’ve paid your down payment and closing costs is crucial. Lenders refer to this as cash reserves, and it’s their assurance that you won’t be left financially vulnerable after buying your home. These funds act as a safety net, showing that you can handle unexpected repairs or a temporary loss of income without missing a mortgage payment. While lenders have specific requirements, having a few months of mortgage payments saved is a good rule of thumb. This isn’t just about satisfying the lender; it’s about giving yourself the financial breathing room you need to enjoy your new home without stress.

Steps to Take Before You Apply
Jumping into the mortgage application process without a little prep is like running a marathon without training. You can do it, but it’s going to be a lot harder. Taking a few key steps beforehand not only makes the process smoother but can also help you secure a better loan with more favorable terms. Think of it as putting your financial life in order so you can present the strongest possible case to lenders. It’s about taking control and setting yourself up for success from day one.
Lower Your Existing Debt
One of the first things lenders look at is your debt-to-income (DTI) ratio. This is simply a measure of your total monthly debt payments compared to your gross monthly income. Lenders usually prefer this number to be 43% or less, including your potential new mortgage. To get yourself in the best position, focus on paying down high-interest debts like credit card balances or personal loans. This does two great things: it lowers your DTI ratio, which lenders love to see, and it frees up more of your monthly income. A lower DTI signals that you can comfortably handle a mortgage payment, making you a much more attractive applicant when you’re ready to apply for a loan.
Build Your Credit and Savings
Your credit score is a major factor in what interest rate you’ll be offered. A better credit score can get you a lower interest rate, potentially saving you thousands of dollars over the life of your loan. The best ways to improve your score are simple but effective: pay every bill on time and keep your credit card balances low. It’s also wise to avoid opening any new credit accounts right before you apply for a mortgage. Alongside your credit, building your savings is crucial. You’ll need funds for a down payment and closing costs, but lenders also want to see that you have cash reserves left over. This shows you’re financially stable and can handle unexpected homeownership costs. Our clients’ success stories often start with these foundational steps.
Review Your Income and Spending
Before you can know how much house you can afford, you need a crystal-clear picture of your finances. It’s time to create a detailed budget. Track your income, all your debts (like student loans and car payments), and your regular spending on everything from groceries to subscriptions. This isn’t about restricting yourself; it’s about empowering yourself with knowledge. Once you see where your money is going, you can confidently determine a realistic monthly mortgage payment. As a starting point, many experts suggest your mortgage payment shouldn’t exceed 28% of your gross monthly income. Knowing your budget helps you explore the right loan programs for your specific financial situation.

Frequently Asked Questions
Should I borrow the maximum amount I’m pre-approved for? Think of your pre-approval amount as a ceiling, not a target. Lenders determine that number based on formulas, but they don’t know about your other financial goals, like saving for retirement or traveling. It’s almost always wiser to choose a loan amount that feels comfortable in your personal budget, leaving you plenty of room for savings, unexpected costs, and the life you want to live outside of your house payments.
What’s more important: my housing costs (the 28% rule) or my total debt (the 36% rule)? Lenders look at both, but your total debt-to-income ratio (the 36% rule) often carries more weight in the final decision. While your housing cost is a huge piece of the puzzle, your total debt gives lenders a complete picture of your financial obligations. It shows them how well you can manage a new mortgage payment on top of your existing payments, like car loans or student debt, which is a key indicator of your ability to repay the loan.
How do lenders look at my income if I’m self-employed or work on commission? Lenders understand that not everyone earns a steady paycheck. If your income is variable, they will typically ask for the last two years of your tax returns to calculate a stable monthly average. Their goal is to see a consistent and reliable history of earnings over time. As long as you have clear documentation showing your income, being self-employed or working on commission won’t stand in the way of getting a mortgage.
Is it better to use my savings for a larger down payment or keep it as cash reserves? This is a great question that comes down to finding the right balance. A larger down payment can lower your monthly payment and help you avoid private mortgage insurance (PMI), which saves you money every month. However, having cash reserves is your financial safety net for emergencies. It’s often best to contribute enough for a solid down payment while ensuring you still have several months of living expenses saved. Your loan officer can help you run the numbers to see what makes the most sense for your situation.
What if my budget feels tight even if I’m within the recommended guidelines? Trust your gut. These guidelines are just starting points, not strict rules that work for everyone. Your personal budget is the ultimate authority. If a potential mortgage payment makes you feel anxious or leaves no room for savings and fun, it’s too high for you, regardless of what a calculator says. The goal is to find a home that enhances your life, not one that adds constant financial stress.
