How Much House Can You Afford in 2026?

Every house hunt starts with the same question, and almost nobody gets a straight answer to it. Real estate sites show you what you might qualify for. Lenders tell you what they're willing to lend. Neither of those is the same as what you can comfortably afford — and the gap between them is where people get into trouble.

Here's how the arithmetic actually works in 2026, with a worked example and a table you can find your own salary in.

The short answer

Most US households can afford a home priced at roughly 3 to 3.5 times their gross annual income, assuming little other debt and a standard down payment. At today's rates that multiple has quietly shrunk — five years ago the same rule of thumb was closer to 4x, because money was cheaper.

So on an $80,000 salary you're looking at somewhere around $280,000, not the $400,000 the same income would have stretched to when rates were near 3%. That's the single biggest thing that has changed about home affordability, and it's worth internalising before you start looking at listings.

The 28/36 rule, properly explained

Lenders don't use a multiple of income. They use two ratios, and understanding both tells you more than any calculator output:

• The 28% front-end ratio. Your total monthly housing payment — mortgage principal, interest, property tax and insurance — should stay under 28% of your gross (pre-tax) monthly income.
• The 36% back-end ratio. All your monthly debt payments combined — that housing payment plus car loans, student loans and minimum credit card payments — should stay under 36% of gross monthly income.

The second one is the one that surprises people. You can pass the 28% test comfortably and still be turned down, or approved for far less than you expected, because a car payment is eating the space between 28% and 36%.

Note that both ratios use gross income, not take-home pay. Your actual paycheck is smaller — which is exactly why borrowing the maximum feels tighter in real life than it looks on paper. If you want to see the difference, run your salary through the Paycheck Calculator.

A worked example: $80,000 a year

Let's take it step by step, because seeing the mechanics makes every other number make sense.

1. Gross monthly income: $80,000 ÷ 12 = $6,667
2. 28% of that: $6,667 × 0.28 = $1,867 — your total monthly housing budget
3. Subtract the parts that aren't the loan: property tax on a home in this range runs about $260 a month, and insurance about $150. That leaves roughly $1,457 for principal and interest.
4. Work backwards to a loan: $1,457 a month at 6.65% over 30 years supports a loan of about $227,000.
5. Add your down payment: with 20% down ($57,000), that's a home priced around $284,000.

The 36% back-end limit for this income is $2,400, so after the $1,867 housing payment there's about $533 a month of room left for every other debt you carry. That's the real constraint for most buyers.

What each salary buys in 2026

Same assumptions throughout: 20% down, 6.65% over 30 years, 1.1% property tax, $1,800 a year insurance, and no other debt.

Two things jump out. First, the relationship is almost perfectly linear — every extra $10,000 of salary buys roughly $37,000 more house. Second, the down payment column grows just as fast, and that's usually the real bottleneck for first-time buyers, not the monthly payment.

What's actually inside the monthly payment

People budget for "the mortgage" and then get blindsided by the bill. A monthly housing payment normally has four parts, often shortened to PITI:

• Principal — the part that actually reduces what you owe.
• Interest — in the early years, the large majority of your payment. On a $227,000 loan at 6.65%, the first payment is about $1,457, and roughly $1,258 of that is pure interest.
• Taxes — property tax, usually collected monthly into an escrow account. The national median is around 1.1% of the home's value per year, but that ranges from about 0.7% in some states to well over 2% in others.
• Insurance — homeowner's insurance, also usually escrowed. Budget $1,500–$2,500 a year in most markets, and considerably more in areas exposed to storms, flooding or wildfire.

Then there are two extras the acronym misses. PMI (private mortgage insurance) applies when you put down less than 20% on a conventional loan, and typically costs 0.5%–1.5% of the loan amount per year — on a $231,000 loan that's roughly $154 a month, buying you nothing but the right to borrow. And HOA dues, if the property has them, can run anywhere from $50 to several hundred a month.

Why existing debt matters more than you'd think

This is where the 36% ratio bites. Take that same $80,000 salary and add monthly debt payments:

Notice the first two rows are identical. Below about $533 a month, other debt doesn't change anything — the 28% front-end ratio is still the binding constraint. Past that point, every extra dollar of monthly debt costs you real buying power: going from $700 to $900 a month in payments knocks roughly $33,000 off the house you can buy.

Which leads to a genuinely useful conclusion: if you're a year out from buying and carrying a car loan you could pay off, doing so may raise your budget more than saving the same money as extra down payment would.

The down payment question

The "you need 20% down" belief keeps more people renting than any other piece of housing folklore. It isn't a requirement — it's the threshold at which PMI goes away:

• FHA loans: 3.5% down with a credit score of 580 or above; 10% down for scores between 500 and 579.
• Conventional loans: many programs start at 3% down for first-time buyers.
• 20% down: no PMI, a smaller loan, and a lower monthly payment — but years more saving.

The honest trade-off is this: a smaller down payment gets you in sooner but costs more every month, and in a market where prices are rising, getting in sooner sometimes wins. In a flat or falling market, it doesn't. Nobody can tell you reliably which market you're in — anyone who claims otherwise is guessing.

How much the interest rate moves things

More than almost any other variable. On a $400,000 loan over 30 years:

• 6.00% → about $2,398 a month in principal and interest
• 6.65% → about $2,568 a month
• 7.50% → about $2,797 a month

That's roughly $400 a month — almost $145,000 over the life of the loan — between the low and high figures, for exactly the same house. It's why improving your credit score before you apply is often worth more than another few thousand in savings, and why locking a rate matters.

What the 28/36 rule doesn't tell you

The ratios are a lending guideline, not a life plan. A few things they can't see:

• Maintenance. Budget around 1% of the home's value per year — about $2,800 on a $284,000 house. Some years it's nothing; the year the water heater and the roof go, it's a lot more.
• Bigger home, bigger everything. Utilities, furnishing, lawn care and property tax all scale with the house.
• Your actual take-home pay. The ratios use gross income. If you're maxing a 401(k) and paying for family health coverage, your real monthly cash flow is far below what a lender sees.
• Emergency savings. Emptying your savings for a down payment and closing costs leaves you one broken furnace from a credit card balance.
• Whether you'll stay. Buying and selling typically costs 8–10% of the price in fees. Under about five years, renting often comes out ahead on pure arithmetic.

A more conservative version many financial planners suggest: keep housing under 25% of take-home pay rather than 28% of gross. It's a noticeably smaller house — and a noticeably easier decade.

What to do next

1. Calculate 28% of your gross monthly income. That's your ceiling, not your target.
2. Add up every other monthly debt payment and check the 36% limit. Whichever number is smaller is your real budget.
3. Get a realiztic property tax rate for the county you're actually shopping in — it moves the answer more than people expect.
4. Run the numbers with the Mortgage Calculator, then try it again at a rate half a point higher to see how much cushion you have.
5. Get pre-approved so you know what a lender will actually offer — then decide, deliberately, to borrow less than that.

The best outcome here isn't the biggest house you qualify for. It's the house you can pay for in a year when things don't go to plan.
