How Much House Can I Afford? A Complete Guide for First-Time Buyers
Learn how to calculate how much house you can afford in 2026 using the 28/36 rule, DTI ratios, and current mortgage rates. Practical examples for every income level.
You found a house you love. The listing photos look great. The neighborhood checks every box. But can you actually afford it?
This is the question that stops more buyers in their tracks than any other. And it should. Buying a home you cannot comfortably afford is one of the fastest ways to wreck your finances for a decade or more. The good news is that lenders have already done a lot of the math for you, and the rules they use are straightforward once you break them down.
What Determines How Much House You Can Afford?
Three numbers do most of the heavy lifting: your income, your existing debt, and the interest rate on your loan. Property taxes and insurance play a role too, but those three are the core variables.
Lenders package all of this into a single metric called your debt-to-income ratio, or DTI. If you have never calculated yours, our Debt-to-Income Ratio Calculator gives you the number in under a minute. It is one of the first things a loan officer will look at when you apply.
The 28/36 Rule: The Standard Most Lenders Use
The 28/36 rule is the backbone of mortgage affordability. It has two parts:
The 28% rule (front-end DTI): Your total monthly housing payment, including principal, interest, property taxes, homeowners insurance, and HOA fees, should not exceed 28% of your gross monthly income.
The 36% rule (back-end DTI): Your total monthly debt obligations, including your housing payment plus all other debts like car loans, student loans, and credit card minimums, should not exceed 36% of your gross monthly income.
These are not hard cutoffs. FHA loans allow front-end DTI up to 31% and back-end up to 43%, sometimes stretching to 50% with strong compensating factors. Conventional lenders following Fannie Mae guidelines typically allow up to 45% back-end DTI, and in specific cases as high as 50% for borrowers with excellent credit and significant reserves.
But the 28/36 guideline is a smart personal finance target. It leaves room to breathe.
How Much House Can You Afford at Current 2026 Rates?
As of mid-2026, the 30-year fixed mortgage rate hovers around 6.5% to 7.0%, according to Freddie Mac's Primary Mortgage Market Survey. That is down from the October 2023 peak of 7.79% but still well above the 3% range of 2020 and 2021.
Here is what affordability looks like at various income levels, assuming 20% down and a credit score of 680 or higher:
| Annual Income | Max Monthly Payment (28%) | Estimated Home Price | Required Down Payment |
|---|---|---|---|
| $50,000 | $1,167 | ~$175,000 | $35,000 |
| $75,000 | $1,750 | ~$265,000 | $53,000 |
| $100,000 | $2,333 | ~$355,000 | $71,000 |
| $125,000 | $2,917 | ~$440,000 | $88,000 |
| $150,000 | $3,500 | ~$530,000 | $106,000 |
| $200,000 | $4,667 | ~$710,000 | $142,000 |
These estimates include a monthly allowance for property taxes ($200 to $400) and homeowners insurance ($100 to $200). Your actual numbers will vary based on your local tax rates, insurance costs, and credit profile.

How Your Down Payment Changes Everything
The down payment is one of the biggest levers you can pull. Here is how the same $100,000 income buyer fares with different down payments on a $355,000 home:
| Down Payment | Down Payment % | Loan Amount | Monthly P&I | PMI Required? |
|---|---|---|---|---|
| $10,650 | 3% (Conventional) | $344,350 | $2,235 + ~$150 PMI | Yes |
| $17,750 | 5% | $337,250 | $2,189 + ~$120 PMI | Yes |
| $35,500 | 10% | $319,500 | $2,073 + ~$80 PMI | Yes |
| $71,000 | 20% | $284,000 | $1,843 | No |
Private Mortgage Insurance (PMI) is required when you put down less than 20% on a conventional loan. PMI typically costs 0.5% to 1.5% of the loan amount per year, adding $100 to $250 per month to your payment on a $300,000 loan. It is not a deal-breaker, but it does reduce how much house you can afford at a given income.

Real-World Scenarios
Sarah: The Freelance Designer in Texas
Sarah is a 34-year-old freelance graphic designer earning $85,000 per year. Her income fluctuates month to month, which makes lenders nervous. She has a $380/month car payment and $180/month in student loan minimums.
Her gross monthly income is $7,083. Under the 28% rule, her max housing payment is $1,983. But her back-end DTI with existing debts ($560/month) plus a $1,983 housing payment comes to $2,543, which is 35.9% of her gross income. She squeaks under the 36% limit.
At a 6.75% rate with 10% down, Sarah can afford a home priced around $270,000. In a market like San Antonio or Fort Worth, that is a solid 3-bedroom starter home. She should also consider using our FHA Loan Calculator since FHA loans are more forgiving of variable income and lower credit scores.
Marcus and Priya: Dual Income, One Car Payment
Marcus earns $72,000 as a physical therapist. Priya earns $68,000 as a marketing manager. Combined gross income: $140,000, or $11,667 per month. Their only debt is a $450/month car payment.
Under the 28/36 rule, their max housing payment is $3,267. Back-end DTI with the car payment: $3,717, which is 31.9% of gross. Well under 36%.
With 20% down at 6.5%, they can afford a home around $510,000. In most Midwest and Southern markets, that buys a 4-bedroom in a good school district. They should run the numbers through our Mortgage Calculator to see the full amortization schedule and understand how much of their early payments go toward interest versus principal.
Common Mistakes First-Time Buyers Make
1. Ignoring the true cost of homeownership. The mortgage payment is just the start. Property taxes, insurance, maintenance (typically 1% to 2% of the home's value per year), and utilities add up fast. A $2,200 mortgage payment can easily become $2,800 in total monthly housing costs.
2. Not checking DTI before house hunting. The most common reason mortgage applications get denied is not low income. It is high DTI from existing debt. Every dollar of monthly debt you carry reduces your borrowing power. A $400/month car payment can reduce your affordable home price by $35,000 to $40,000.
3. Shopping for homes before getting pre-approved. Pre-approval gives you a concrete number. Without it, you are guessing, and sellers will not take your offer seriously.
4. Forgetting closing costs. Budget 2% to 5% of the purchase price for closing costs. On a $350,000 home, that is $7,000 to $17,500 in cash you need on top of your down payment.
Should You Rent Instead?
Before committing to a purchase, it is worth comparing the true cost of owning versus renting in your market. In 2026, the national breakeven point for buying versus renting is about 6 years, according to Zillow's June 2026 analysis. In affordable Midwest cities like Columbus and Indianapolis, that drops to 4 years. In San Francisco and San Jose, buying never surpasses renting over a 30-year horizon.
Our Rent vs. Buy Calculator runs the full comparison for your specific market and time horizon.
If you already own and are considering refinancing, the math is different but related. Our Refinance Calculator can tell you whether a rate drop of 0.5% or more would save you enough to justify the closing costs.

It depends on your loan type. Conventional loans allow as little as 3% down. FHA loans require 3.5% down with a 580+ credit score. VA and USDA loans require 0% down for eligible borrowers. Putting 20% down eliminates PMI on conventional loans.
What is the 28/36 rule for mortgages?
The 28/36 rule says your housing payment should not exceed 28% of your gross monthly income, and your total monthly debts (including housing) should not exceed 36%. It is a guideline, not a law, but it is a reliable benchmark for sustainable homeownership.
