How Much House Can You Afford? Home Affordability Guide 2026
Most people figure out their home budget the wrong way. They walk into a bank, ask what they qualify for, and treat that number as their target. That is how you end up house poor – technically approved, practically broke every month.
In 2026, with rates still well above what most buyers were used to a few years ago, the gap between what a lender will give you and what you can actually handle has never mattered more. This guide breaks down how house affordability actually works – the math behind it, what lenders look at, and how to use our free House Affordability Calculator to find a number you can live with.
What Is House Affordability?
House affordability is not the maximum loan a bank will approve. It is the home price you can buy while still paying your other bills, saving for retirement, and not breaking into a cold sweat every time an unexpected expense shows up.
A lender might approve you for $500,000. But once you add up property taxes, insurance, maintenance, utilities, and your existing debts, your real comfortable budget might be $350,000. The bank does not care about your retirement contributions or your kid’s tuition. You do.
The 28/36 Rule
The 28/36 rule is the oldest and most practical guideline for home affordability. Lenders and financial advisors have used it for decades for a simple reason – it works.
The front-end limit is 28%. Your total monthly housing costs – principal, interest, property taxes, and homeowner insurance – should stay below 28% of your gross monthly income. The back-end limit is 36%. Add up every monthly debt payment you have (housing included), and that total should not exceed 36% of gross income.
Here is what that looks like on an $8,000/month income:
| Rule | Calculation | Max Monthly Amount |
|---|---|---|
| 28% Front-End | $8,000 x 0.28 | $2,240 (housing only) |
| 36% Back-End | $8,000 x 0.36 | $2,880 (all debts combined) |
If you already pay $400/month on a car and $200/month in student loans, that leaves only $2,280 for housing – not $2,880. That gap matters when you are budgeting for a real purchase.
What Lenders Actually Look At
When you apply for a mortgage, your debt-to-income ratio (DTI) is the number that matters most. Most conventional lenders cap back-end DTI at 43%. Some go to 50% for strong borrowers. FHA loans can stretch further. But DTI is only one piece.
| Factor | What Lenders Want | Why It Matters |
|---|---|---|
| Credit Score | 620+ conventional, 580+ FHA | Determines your interest rate |
| DTI Ratio | Below 43% back-end | Measures debt load vs income |
| Down Payment | 3% to 20%+ | Affects loan size and PMI |
| Employment History | 2+ years stable | Proves income is reliable |
| Cash Reserves | 2 to 6 months of payments | Shows you have a cushion |
| Loan-to-Value | Below 80% to avoid PMI | Lender risk measurement |
What Actually Moves Your Affordability Number
Income
Every affordability formula starts here. Lenders work from gross income – before taxes – and they want to see it documented. Salary, consistent bonuses, freelance income, rental income, and dividends all count as long as you can prove them. Sporadic side income usually does not.
Existing Debts
This is where buyers most often underestimate the problem. Every monthly debt payment – car loans, student loans, credit card minimums, personal loans, child support – eats directly into your mortgage budget. Pay off a $400/month car loan before you apply and your maximum home price can jump by $50,000 or more depending on your rate and term.
Down Payment
More down means a smaller loan, lower monthly payment, and no PMI once you clear 20%. On a $400,000 home, going from 5% to 20% down cuts $60,000 from your loan principal and eliminates PMI that can run $100 to $300/month on top of your payment. That is real money every single month.
Interest Rate
A 1% difference in rate on a $350,000 mortgage is roughly $200/month. Over 30 years that is $72,000. This is why your credit score and the lender you choose both matter – not just for approval, but for how much home your monthly budget can actually reach.
Property Taxes and Insurance
These two costs catch more buyers off guard than anything else. New Jersey property taxes average over 2% of home value per year. Texas is around 1.8%. California is closer to 0.7%. That difference alone can shift your effective monthly payment by hundreds of dollars on the same purchase price. Homeowner insurance adds another $1,000 to $3,000 a year. Both count toward your front-end DTI ratio.
How Much House Can You Afford by Income?
The 3x to 5x income rule is a rough starting point. The table below gives more specific estimates based on a 30-year mortgage at 6.5%, 20% down, and minimal existing debt. Your number will differ based on your actual debts, local taxes, and credit score.
| Annual Income | Monthly Income | Max Housing Payment (28%) | Estimated Home Price |
|---|---|---|---|
| $50,000 | $4,167 | $1,167 | $175,000 |
| $75,000 | $6,250 | $1,750 | $260,000 |
| $100,000 | $8,333 | $2,333 | $350,000 |
| $125,000 | $10,417 | $2,917 | $435,000 |
| $150,000 | $12,500 | $3,500 | $520,000 |
| $200,000 | $16,667 | $4,667 | $695,000 |

How Down Payment Changes Your Monthly Payment
Same home, same rate, very different monthly costs depending on how much you put down. Here is a $350,000 home at 6.5% on a 30-year term:
| Down Payment | Amount Down | Loan Amount | Monthly Payment | PMI? |
|---|---|---|---|---|
| 3% | $10,500 | $339,500 | ~$2,147 + PMI | Yes, ~$170/mo |
| 5% | $17,500 | $332,500 | ~$2,103 + PMI | Yes, ~$150/mo |
| 10% | $35,000 | $315,000 | ~$1,993 + PMI | Yes, ~$100/mo |
| 20% | $70,000 | $280,000 | ~$1,771 | No |
That is a $376/month difference between 3% and 20% down. Use our Down Payment Calculator to build a savings plan toward a target amount.
The 2026 Market Reality
Rates in the 6-7% range are not going away quickly. That is the main story for buyers in 2026. Prices in most metro areas have not come down meaningfully, and the payment math is significantly harder than it was in 2020 or 2021. A home that cost $1,100/month then can cost $1,700/month now at the same price because of the rate difference alone.
That said, inventory is slowly improving. Sellers who held out for years are starting to list. New construction is moving again, with builders offering rate buydowns that can get you into the 5% range temporarily. And down payment assistance programs have expanded in most states – worth researching before you assume you need 20% saved.
The most important thing you can do before shopping: know your number. Run your DTI ratio and find out what payment you can actually handle – not just what a lender will technically approve.
How to Buy More Home on the Same Budget
- Pay off a debt before applying – even eliminating one car payment can add $30,000 to $60,000 to your home budget
- Save a larger down payment – getting to 20% eliminates PMI and reduces your monthly payment considerably
- Raise your credit score before shopping – going from 680 to 740 can shave 0.3 to 0.5% off your rate, which adds up fast on a $300,000+ loan
- Shop at least 3 lenders – rate offers vary more than most buyers expect; getting multiple quotes takes an afternoon and can save thousands
- Consider FHA if you are a first-time buyer – FHA loans accept credit scores as low as 580 and require only 3.5% down
- Check VA eligibility – if you served, VA loans require zero down and have no PMI
- Get pre-approved before you look – it prevents the very common mistake of shopping above your range and getting emotionally attached to a home you cannot buy
Frequently Asked Questions
How much house can I afford on a $70,000 salary?
At $70,000/year your gross monthly income is about $5,833. The 28% rule puts your maximum housing payment at around $1,633/month. At 6.5% on a 30-year loan with 10% down and average taxes and insurance, that works out to roughly $240,000 to $270,000 depending on where you live. Use the calculator with your actual local tax rate for a tighter estimate.
Is the 28/36 rule still relevant in 2026?
Lenders will approve higher DTIs – up to 43% back-end conventionally, more with FHA. But approval and comfort are different things. With rates where they are in 2026, stretching to the limit of your approval leaves almost no buffer for repairs, job changes, or any other financial curveball. The 28/36 numbers are conservative for a reason.
Does the house affordability calculator include PMI?
Yes. Our House Affordability Calculator adds PMI to the monthly estimate automatically when your down payment is below 20%. PMI typically runs 0.5% to 1.5% of the loan amount per year and drops off once you hit 20% equity.
What is the difference between pre-qualification and pre-approval?
Pre-qualification is informal – the lender takes your word on income and debts and gives you a rough number. It takes minutes and means almost nothing to sellers. Pre-approval involves verifying your documents and credit, and it produces a conditional commitment letter. In a competitive market, sellers often will not entertain offers without one.
Should I max out my approved budget?
Almost never. Buying at your approval ceiling means any financial disruption – a job change, a car repair, a medical bill – immediately becomes a crisis. Most financial planners suggest buying at 80% to 90% of your maximum to keep some breathing room. Homes also cost more than the mortgage: maintenance alone typically runs 1% to 2% of home value per year.
How does credit score affect how much house I can afford?
A lot more than people expect. The difference between a 640 and a 760 credit score can be close to 1% on your mortgage rate. On a $350,000 loan that is roughly $230/month – or about $33,000 in buying power when you translate it back into home price. If your score is below 720, spending 6 months improving it before applying is often worth the wait.
