Key takeaways
- A common guideline is to keep housing costs under about 28% of gross monthly income and total debts under about 36%.
- Your full payment includes principal, interest, property tax, insurance and possibly HOA dues and PMI.
- A larger down payment lowers your monthly cost and can remove the need for PMI.
- Budget for closing costs, moving and repairs, not only the down payment.
Buying a home is usually the largest purchase of your life, and the amount a lender approves is not always the amount you should spend. The goal is a home that fits comfortably inside your budget while leaving room for savings, emergencies and the rest of your life.
The 28/36 rule
Many lenders and planners use a simple guideline:
- 28%: total housing costs should be no more than about 28% of your gross monthly income.
- 36%: all debt payments combined, including housing, car loans, student loans and cards, should be no more than about 36%.
For example, with a gross income of $90,000 a year, or $7,500 a month, 28% is $2,100 a month for housing. If you already pay $500 a month toward other debts, the 36% cap of $2,700 leaves $2,200 for housing, so $2,100 is the tighter limit.
What goes into your monthly payment
- Principal and interest: repaying the loan itself
- Property taxes: vary widely by location
- Homeowners insurance: required by lenders
- PMI: private mortgage insurance, usually required on conventional loans with less than 20% down
- HOA dues: for many condos and planned communities

Factors that change what you can afford
Credit score
A higher score usually means a lower interest rate, which can change your monthly payment significantly on a large loan. Learn more in what is a good credit score.
Down payment
Putting 20% down on a conventional loan avoids PMI. Many buyers put down less, and some loan programs allow very low down payments, but a smaller down payment means a bigger loan and higher monthly costs.
Loan term
A 15-year mortgage has higher payments but far less total interest than a 30-year loan. A 30-year loan keeps payments lower and more flexible.
Do not forget upfront and ongoing costs
| Cost | Why it matters |
|---|---|
| Closing costs | Lender fees, appraisal, title and taxes, often a few percent of the loan |
| Moving and furnishing | Easy to underestimate |
| Maintenance | Many owners budget around 1% to 2% of the home value per year |
| Emergency fund | Keep savings after closing for surprise repairs |
How lenders decide how much you can borrow
When you apply for a mortgage, a lender is trying to answer one question: how likely are you to repay this loan on time for the next 15 to 30 years? To answer it, they look at a handful of factors together rather than any single number.
- Income and job stability. Lenders usually want to see steady income over the past two years. Salaried workers typically provide pay stubs and W-2s, while self-employed borrowers often need two years of tax returns.
- Debt-to-income ratio (DTI). This compares your monthly debt payments with your gross monthly income. It is the backbone of the 28/36 rule and one of the most important numbers in your application.
- Credit score and history. A higher score generally unlocks lower interest rates and better loan options, while late payments and high card balances can raise your costs or limit your choices.
- Down payment and savings. A larger down payment lowers the lender’s risk. Many lenders also like to see cash reserves left over after closing, often measured in months of mortgage payments.
- The property itself. The home must appraise for at least the purchase price, and some loan types have rules about the condition of the property.
The key point is that a lender’s maximum approval is based on what you can technically repay, not on what feels comfortable in your real life. It does not know about your childcare costs, your plans to travel or how much you want to invest for retirement. That is why your own budget should set the ceiling, not the preapproval letter.
Front-end and back-end ratios, worked through
The 28/36 rule uses two ratios. The front-end ratio looks only at housing costs, including principal, interest, property taxes, homeowners insurance, HOA dues and mortgage insurance. The back-end ratio adds every other monthly debt payment, such as car loans, student loans, personal loans and credit card minimums.
The table below uses example incomes to show how the rule translates into a monthly housing budget. These figures are illustrations of the math, not recommendations for your situation.
| Gross annual income (example) | Gross monthly income | 28% housing limit | 36% total debt limit |
|---|---|---|---|
| $50,000 | $4,167 | $1,167 | $1,500 |
| $75,000 | $6,250 | $1,750 | $2,250 |
| $100,000 | $8,333 | $2,333 | $3,000 |
| $150,000 | $12,500 | $3,500 | $4,500 |
Always check both limits. If you earn $75,000 and already pay $700 a month toward a car loan and student loans, the 36% cap of $2,250 leaves only $1,550 for housing. In that case the back-end ratio, not the 28% figure, is what limits you. Paying down other debts before you buy can raise the housing budget you can safely handle.
How big a down payment do you really need?
Twenty percent down is often described as the gold standard, but it is not a requirement for every buyer. Many conventional loans allow smaller down payments, and some government-backed programs, such as FHA, VA and USDA loans in the United States, are designed for buyers with smaller savings or specific eligibility. Program rules and limits change, so confirm the current details with a lender or the program’s official website.
The trade-offs of putting down less
- A bigger loan. Borrowing more means paying more interest over the life of the loan.
- Mortgage insurance. Conventional loans with less than 20% down usually require private mortgage insurance (PMI), and FHA loans have their own mortgage insurance premiums.
- Less equity cushion. If home prices dip soon after you buy, a small down payment can leave you owing close to, or more than, the home is worth.
The trade-offs of putting down more
- Lower monthly payments and often a better rate.
- Less cash on hand for repairs, furniture and emergencies after you move in.
- Money tied up in the house, which is not easy to access without selling or borrowing against it.
A balanced approach is to make the largest down payment you can while still keeping a solid emergency fund in the bank after closing. Draining every dollar of savings to reach 20% can leave you exposed the first time the water heater fails.
Should you rent or buy right now?
Buying can build equity and give you stability, but it is not automatically better than renting. The right choice depends on your plans, your finances and your local market.
| Buying may make sense if you… | Renting may make sense if you… |
|---|---|
| Plan to stay in the area for at least five years | Might move for work or family in the next few years |
| Have a stable income and an emergency fund | Are still building savings or paying off high-interest debt |
| Want control over renovations and décor | Prefer the landlord to handle repairs and maintenance |
| Can comfortably afford the full monthly cost of owning | Would be stretched thin by a mortgage plus upkeep |
Buying and selling a home both come with significant transaction costs, such as closing costs and agent fees. If you sell after only a year or two, those costs can wipe out any equity you built. That is why time horizon matters so much in the rent-or-buy decision.
Ways to increase what you can comfortably afford
- Pay down existing debt. Lowering car, student loan or card payments improves your back-end ratio and frees up monthly cash.
- Improve your credit score. Paying on time and lowering credit card balances can help you qualify for a better rate, which lowers your payment on the same loan amount.
- Save a larger down payment. A bigger down payment reduces the loan and may remove the need for PMI.
- Shop several lenders. Rates and fees vary between lenders. Comparing official Loan Estimates side by side can save a meaningful amount over the life of the loan.
- Look at total cost, not just price. A slightly cheaper home in an area with much higher property taxes or insurance can cost more each month.
- Consider a longer search. Being patient and flexible on location, size or condition can bring the right home into your budget.
A step-by-step plan to set your home budget
- Start with your monthly budget. List your take-home pay and current spending to see what you can truly put toward housing each month.
- Apply the 28/36 rule to your gross income as a sanity check.
- Estimate the full payment with the calculator above, using local tax rates, an insurance quote and any HOA dues.
- Add an ownership buffer. Set aside money each month for maintenance and repairs.
- Decide on your down payment and confirm you will still have an emergency fund after closing.
- Get preapproved and compare offers from multiple lenders.
- Set a firm maximum price before you start touring homes, and share it with your agent.
Common mistakes first-time buyers make
Most home-buying regrets come from a few predictable mistakes. Knowing them in advance makes them much easier to avoid.
- Shopping by the approval amount. The preapproval letter shows the most a lender will offer, not the most you should spend. Set your own limit first.
- Ignoring the full monthly cost. Principal and interest are only part of the picture. Property taxes, insurance, HOA dues and mortgage insurance can add hundreds of dollars a month.
- Forgetting maintenance. Roofs, appliances, heating systems and plumbing all wear out eventually. Setting aside money every month turns a future emergency into a planned expense.
- Opening new credit before closing. Financing a car or furniture while your mortgage is in process can change your debt-to-income ratio and put your approval at risk. Wait until after closing.
- Skipping the inspection. A professional home inspection can uncover costly problems before you commit, giving you the chance to negotiate repairs or walk away.
- Not comparing lenders. Accepting the first offer can mean paying a higher rate or more fees than necessary. Request quotes from several lenders on the same day so you can compare them fairly.
- Emptying your savings. Arriving at your new home with no cash cushion makes every surprise stressful. Keep an emergency fund intact after closing.
If you avoid these traps and buy a home that fits comfortably within your budget, owning can be a stable foundation for your finances rather than a source of constant pressure.
Frequently Asked Questions
How much house can I afford on a $60,000 salary?
Using the 28% guideline, $60,000 a year is $5,000 a month in gross income, so total housing costs of about $1,400 a month would fit the rule. The home price that payment supports depends heavily on your interest rate, down payment, property taxes and insurance, so run your numbers through a mortgage calculator using real local figures.
Does my credit score affect how much house I can afford?
Yes. Your score influences the interest rate you are offered, and a lower rate means a lower monthly payment for the same loan amount. A stronger score can also give you access to more loan options with better terms.
Should I buy the most expensive house I am approved for?
Usually not. Lenders approve you based on your ability to repay, not on your other goals. Buying below your maximum approval leaves room for savings, retirement contributions and life’s surprises.
How much should I have saved besides the down payment?
Plan for closing costs, moving expenses, basic furniture and early repairs. Many buyers also aim to keep at least three to six months of essential expenses in an emergency fund after closing.
Is a 15-year or 30-year mortgage better?
A 15-year mortgage costs far less in total interest but has higher monthly payments. A 30-year mortgage keeps payments lower and more flexible. If you choose a 30-year loan, you can usually make extra principal payments when you are able to, which shortens the loan without locking you into a higher required payment.
The bottom line
Use the 28/36 rule as a starting point, run your real numbers through a mortgage calculator and keep a healthy emergency fund after closing. The right house is the one that still lets you sleep well at night.
Your next step is simple: add up your monthly take-home pay and current debts, run a few scenarios in the mortgage calculator above, and write down the highest monthly payment you would be comfortable making even in a tight month. That number, not the lender’s maximum, is your real home budget. Once you have it, you can shop with confidence and negotiate from a position of strength.
