How Much House Can I Afford? A Complete Affordability Guide

How Much House Can I Afford? A Complete Affordability Guide

How much house you can afford depends on your income, debts, down payment, credit score, interest rate, and local costs like property taxes and insurance. A common guideline is the 28/36 rule: spend no more than 28% of gross monthly income on housing costs and no more than 36% on total debt. For example, a household earning $100,000 per year can typically afford a home priced between $350,000 and $450,000, depending on debts and down payment. Getting pre-approved with a lender gives you the most accurate number.

One of the first questions every home buyer asks is how much house they can afford. The answer depends on your specific financial situation and the costs of homeownership in your area. According to the National Association of Realtors, the median existing-home sale price was approximately $407,500 as of early 2025, and the average 30-year fixed mortgage rate was around 6.7% as of early 2026 per Freddie Mac. This guide walks you through the calculations and rules that determine your home buying budget.

The 28/36 Rule Explained

The most widely used affordability guideline is the 28/36 rule:

The 28% rule (front-end ratio): Your total monthly housing costs should not exceed 28% of your gross monthly income. Housing costs include your mortgage principal and interest, property taxes, homeowners insurance, and any HOA fees.

The 36% rule (back-end ratio): Your total monthly debt payments, including housing costs plus all other debts (car payments, student loans, credit card minimums, personal loans), should not exceed 36% of your gross monthly income.

Example: If your household earns $8,000 per month gross, the 28% rule means your housing costs should stay below $2,240, and the 36% rule means your total debt payments should stay below $2,880.

Keep in mind that these are guidelines, not hard limits. FHA loans allow DTI ratios up to 43% to 50%. Conventional loans allow up to 45% in some cases. Just because a lender will approve a higher ratio does not mean it is wise to borrow that much. For a deeper dive, see our debt-to-income ratio guide.

The Consumer Financial Protection Bureau recommends that borrowers carefully consider their total financial picture before committing to a mortgage, not just the monthly payment.

Affordability by Income Level

Here are estimates assuming a 30-year fixed mortgage at 6.5%, 5% down payment, and property taxes and insurance totaling 2% of home value annually:

$50,000 income — Approximately $200,000-$225,000 home; Monthly payment around $1,400.

$75,000 income — Approximately $300,000-$340,000 home; Monthly payment around $2,100.

$100,000 income — Approximately $400,000-$450,000 home; Monthly payment around $2,800.

$150,000 income — Approximately $600,000-$680,000 home; Monthly payment around $4,200.

$200,000 income — Approximately $800,000-$900,000 home; Monthly payment around $5,600.

These are estimates. Your actual affordability depends on your specific debts, credit score, down payment, location, and the interest rate you qualify for.

How to Calculate Your Maximum Home Price

Here is a step-by-step approach:

Step 1: Determine Your Monthly Gross Income

This is your pre-tax household income from all sources. If you and your co-borrower earn a combined $100,000 per year, your monthly gross is $8,333.

Step 2: Calculate Your Maximum Monthly Housing Cost

Multiply your gross monthly income by 0.28 to get the conservative target, or by the DTI ratio your target loan program allows. At 28%, that is $8,333 times 0.28 equals $2,333.

Step 3: Subtract Estimated Property Taxes and Insurance

Research property tax rates in your area (typically 0.5% to 2.5% of home value per year) and homeowners insurance costs ($100 to $300 per month). If taxes and insurance total $500 per month, your remaining budget for mortgage principal and interest is $2,333 minus $500 equals $1,833.

Step 4: Determine the Loan Amount

Using current mortgage rates and your desired loan term, calculate the loan amount that produces a monthly principal and interest payment of $1,833. At a 6.5% rate on a 30-year fixed, $1,833 per month supports a loan of approximately $290,000.

Step 5: Add Your Down Payment

If you have $30,000 for a down payment, your maximum purchase price is approximately $290,000 plus $30,000 equals $320,000.

This gives you a starting point, but the pre-approval process will give you a precise number based on your actual financial documents. Getting pre-approved with a direct lender through DirectLender.com is the most accurate way to determine your buying power.

What Factors Affect Affordability?

Interest rates are the single biggest factor affecting affordability. A 1% change in rates on a $300,000 loan changes your monthly payment by roughly $180 to $200. According to Freddie Mac, rates have fluctuated significantly in recent years, making it critical to lock when you find a favorable rate.

Your credit score directly impacts your interest rate. Borrowers with scores above 760 qualify for the best rates, while those with scores in the 620 to 660 range may pay 0.5% to 1.5% more. To understand all the factors that drive mortgage pricing, see our guide on understanding mortgage rates. This rate difference can reduce the home price you can afford by $20,000 to $50,000.

Your down payment affects both the loan amount and whether you need mortgage insurance. A 20% down payment eliminates PMI, which reduces your monthly costs and increases the home price you can afford. For first-time home buyers, down payment assistance programs can help bridge the gap.

Property taxes vary dramatically by location. According to the Tax Foundation, effective property tax rates range from 0.31% in Hawaii to 2.23% in New Jersey. These differences can mean hundreds of dollars per month in housing cost variation.

HOA fees add a fixed monthly cost that reduces the amount available for your mortgage payment. HOA fees typically range from $150 to $500 per month for condos and townhomes.

The Hidden Costs of Homeownership

When calculating affordability, factor in costs beyond the mortgage:

Maintenance and repairs: Budget 1% to 2% of the home's value per year for upkeep. On a $350,000 home, that is $3,500 to $7,000 annually.

Utilities: Homeowners typically pay more for utilities than renters. Budget $200 to $400 per month depending on your climate and home size.

Lawn care and landscaping: If you are moving from an apartment to a house, plan for $50 to $200 per month.

Furniture and setup: A new home often needs furniture, window treatments, appliances, and other items. This can easily total $5,000 to $15,000.

Emergency fund: Homeowners should maintain a larger emergency fund to cover unexpected repairs.

A good rule of thumb is to keep your total monthly housing expenses (mortgage, taxes, insurance, HOA, maintenance, and utilities) below 35% to 40% of your gross income.

How Your Loan Program Affects Affordability

The type of mortgage you choose significantly impacts how much home you can afford.

FHA loans require only 3.5% down but add upfront and annual mortgage insurance premiums. The annual MIP of 0.55% adds about $137 per month on a $300,000 loan. Read more in our FHA loans guide.

VA loans require zero down payment and have no PMI, which maximizes your purchasing power. A veteran with the same income as a non-veteran buyer can typically afford $20,000 to $40,000 more home because they are not paying mortgage insurance. See our VA home loans guide.

Conventional loans with 20% down avoid PMI entirely. With less than 20% down, PMI adds 0.3% to 1.5% of the loan amount annually.

[Jumbo loans](/learn/jumbo-loans-explained) for higher-priced properties may require larger down payments (10% to 20%) and have stricter DTI requirements.

How to Improve Your Affordability

If the numbers show you cannot afford the home you want, there are several strategies to increase your buying power.

Improve your credit score. A higher credit score qualifies you for a lower interest rate. Paying down credit card balances and correcting errors on your credit report are the fastest ways to boost your score.

Pay down existing debt. Reducing your monthly debt obligations lowers your DTI ratio. Paying off a $300 per month car payment could increase your home buying budget by $50,000 or more.

Increase your down payment. A larger down payment reduces your loan amount and may eliminate the need for mortgage insurance. Explore down payment assistance programs in your area.

Consider a different loan program. VA loans and USDA loans offer zero down payment, which maximizes the purchase price you can afford. FHA loans offer low down payments and flexible DTI limits.

Buy in a more affordable area. Property taxes, insurance costs, and home prices vary dramatically by location. Moving even 20 miles in some markets can reduce your housing costs by 20% to 30%.

What You Can Afford vs. What You Should Spend

Lenders will often approve you for more than you should comfortably spend. Just because you qualify for a $450,000 mortgage does not mean you should borrow that much. Consider your lifestyle goals, future plans (children, career changes, education), retirement savings, and comfort level with the monthly payment.

Many financial advisors recommend spending no more than 25% of your take-home pay (after taxes) on housing. This is more conservative than the 28% of gross income rule but leaves more room for other financial goals. According to the Bureau of Labor Statistics, the average American household spends approximately 33% of income on housing, suggesting many households are stretched thin.

The best approach is to calculate your maximum qualification, then decide based on your personal budget and priorities what you are truly comfortable spending. ## Online Affordability Tools vs. Professional Pre-Approval

Online mortgage affordability calculators are a useful starting point, but they have limitations. Most calculators use simplified assumptions about property taxes, insurance, and interest rates. They do not know your actual credit score, debt balances, or the specific loan programs you qualify for. The numbers they produce are estimates at best.

Professional pre-approval from a lender gives you a much more accurate picture. During pre-approval, a loan officer reviews your actual pay stubs, tax returns, bank statements, and credit report. They calculate your qualifying income according to specific program guidelines, determine your precise DTI ratio, and identify the loan programs you are eligible for. The result is a real number backed by a real commitment.

According to the Mortgage Bankers Association, borrowers who get pre-approved before shopping close faster and are more likely to get their offers accepted. Through DirectLender.com, you can get pre-approved by multiple direct lenders to compare your options.

Affordability in Different Market Conditions

Affordability fluctuates with market conditions. When interest rates rise, your monthly payment increases on the same loan amount, which means you can afford a less expensive home on the same income. When rates fall, your buying power expands. According to Freddie Mac, the 30-year fixed rate has ranged from below 3% in 2021 to above 7% in 2023, creating dramatic swings in affordability.

Home prices also play a role. In markets where prices are rising rapidly, waiting to buy can mean paying more for the same home. In cooling markets, patience may be rewarded. Your real estate agent and loan officer can help you evaluate whether current conditions in your target area favor buying now or waiting.

Property tax rates vary widely. According to the Tax Foundation, states like New Jersey, Illinois, and Connecticut have effective rates exceeding 2%, while Hawaii, Alabama, and Louisiana have rates below 0.5%. These differences can shift your affordability by tens of thousands of dollars.

Making the Final Decision

The best approach is to combine the 28/36 rule with your personal financial goals. Calculate your maximum qualification using the steps above, then decide what you are truly comfortable spending. Leave room for the unexpected — a good financial cushion is worth more than a slightly larger house.
