Salary Needed to Buy a Home by State (2026)

“Salary needed to buy a home” is not a single published number — it's a debt-to-income ratio applied to a monthly payment, and the payment moves with price, rate and down payment. This page shows the math behind the figure, how much each input actually moves it, and why the same salary buys a very different home depending on where you live.

Lenders qualify you by a debt-to-income (DTI) ratio, not a flat income rule. HUD's manual-underwriting standard for FHA loans caps housing costs at 31% of gross monthly income and total debt at 43%; conventional lenders commonly use a tighter 28%/36% benchmark. Whatever ratio applies, the required salary is simply the monthly PITI payment divided by that ratio, annualized — which means down payment and interest rate move the number as much as home price does.

The DTI math behind the number

A lender's ability-to-repay analysis compares your monthly obligations to your gross monthly income. HUD's Handbook 4155.1 sets the standard manually-underwritten FHA benchmark at 31% for the mortgage payment-to-income ratio and 43% for total fixed payments (mortgage plus all recurring debt) to income — ratios that can be exceeded only with documented compensating factors like cash reserves or minimal payment shock. The National Association of Realtors' Housing Affordability Index uses a different, tighter assumption for its own published index: a 25% qualifying ratio at 20% down, with qualifying income calculated directly from the monthly principal-and-interest payment (payment × 4 × 12). Neither ratio is "the" rule — they're two different published benchmarks for two different purposes — but both work the same way: pick a ratio, compute the payment, divide.

What actually goes into "the payment" matters too. A qualifying PITI payment includes principal, interest, property taxes and homeowners insurance — and, if applicable, HOA dues and mortgage insurance — not just principal and interest. Back-end DTI adds every other recurring debt: car payments, student loans, credit cards, and any other required minimum payment reported to a credit bureau. Two buyers at the identical home price and rate can need very different salaries once their other debt is factored into the 43%-of-everything ceiling.

The ratios aren't absolute: compensating factors

A "salary needed" figure calculated strictly off the 31%/43% or 28%/36% ceilings is a floor on what lenders will consider, not a hard wall every borrower has to clear. HUD's own manual-underwriting guidance names specific, documented circumstances under which a borrower can exceed those standard ratios — meaning two people with the identical qualifying salary calculated above can have genuinely different maximum purchase prices once these are factored in:

  • A down payment of 10% or more toward the purchase.
  • Substantial documented cash reserves — at least three months of housing expenses — left over after closing, subject to specific rules on what counts (retirement-account funds only count at 60% of the vested balance, and only if withdrawals are possible outside of job separation or retirement).
  • A minimal increase in housing expense versus what the borrower already pays.
  • Documented income not reflected in effective income, such as food stamps or similar public benefits that directly affect the ability to pay.
  • Demonstrated ability to accumulate savings and a conservative history with credit.
  • Potential for increased earnings, evidenced by job training or education in the borrower's profession.

None of these change the math in the six-step model below on their own — they're underwriter judgment calls that widen the ratio ceiling itself, which is a separate lever from anything price, rate or down payment can do. A borrower right at the standard-ratio salary threshold with strong reserves and a large down payment is in a materially different position than one at the identical salary with neither.

A worked example, step by step

Take a $415,000 home, 20% down, at a 6.75% 30-year rate, qualified at the conventional 28% front-end ratio. Here is every step from price to required salary:

  1. Loan amount: $415,000 × (1 − 20%) = $332,000 financed.
  2. Monthly rate: 6.75% ÷ 12 = 0.5625% per month.
  3. Monthly P&I: standard 360-month amortization on $332,000 at 0.5625%/month ≈ $2,154.
  4. Add tax + insurance: an illustrative 1.3%/year of price (≈$449/month) brings PITI to roughly $2,603/month.
  5. Divide by the ratio: $2,603 ÷ 28% = $9,296 in required gross monthly income.
  6. Annualize: $9,296 × 12 ≈ $111,600 required salary.

Now run the identical home through the FHA side of the math instead: 3.5% down (FHA's minimum) and the 31% front-end ratio from HUD's own handbook, at the same 6.75% rate.

  1. Loan amount: $415,000 × (1 − 3.5%) ≈ $400,475 financed.
  2. Monthly P&I: 360-month amortization on $400,475 at 6.75% ≈ $2,597.
  3. Add tax + insurance: the same ≈$450/month brings PITI to roughly $3,047/month.
  4. Divide by 31% instead of 28%: $3,047 ÷ 31% ≈ $9,829 in required gross monthly income.
  5. Annualize: ≈ $117,950 required salary.

Even with a wider (more permissive) 31% ratio, the FHA path needs a slightly higher salary here than the 20%-down conventional example above — because the much smaller down payment means a far larger loan amount drives the payment up more than the looser ratio saves. A wider ratio doesn't automatically mean an easier qualification; it depends entirely on which other input moved alongside it.

Every "salary needed" figure anywhere on the internet is this same six-step calculation with different inputs plugged in. Change the down payment, the rate, or the ratio, and only step 1, 2 or 5 changes — the rest of the math is identical. The table below runs that same calculation across four common scenarios at the same $415,000 price, so you can see exactly how much each single input moves the final number:

ScenarioLoan amountIllustrative income needed
3% down, 6.75%$402,550$131,165
10% down, 6.75%$373,500$123,090
20% down, 6.75%$332,000$111,554
20% down, 5.75%$332,000$102,302

Illustrative only: standard 30-year amortization at a 28% front-end ratio, plus an estimated 1.3%/year combined tax-and-insurance load on price. Not a quote — get an actual Loan Estimate from a lender for your specific rate, credit profile and location.

Two things stand out. First, moving from 3% down to 20% down at the same rate cuts the required income by roughly a sixth, because it cuts the loan amount by more than 17% of the price — down payment size is often a bigger lever than people expect, separate from the cash needed at closing. Second, a single percentage point of rate moves the required income by roughly 10–12% on its own, which is why the "salary needed" figure published anywhere is only as current as the rate it assumed; check Freddie Mac's Primary Mortgage Market Survey for the prevailing 30-year average before treating any fixed-rate example as current.

How credit score changes the rate you're quoted — and the salary you need

Rate isn't a single number available to everyone at the same price point — it's priced by risk, and credit score is one of the biggest inputs. The CFPB's own rate-checker tool, built on lender-submitted rate data, shows this directly with a $400,000 purchase example: a 625 credit score was quoted a 6.125%–8.875% rate range, while a 700 score on the identical purchase was quoted 5.875%–8.125% — a roughly quarter-to-three-quarter-point spread depending on where in each range a given lender lands. The CFPB's tool translates that spread into a concrete lifetime cost: the higher-scoring borrower saves up to $264,523 over the life of the loan on that example.

Running those same rate-range endpoints through this page's six-step model, at CFPB's own $400,000 purchase price and 20% down, shows the required-income spread directly:

Credit tier & rate (CFPB example)Illustrative income needed
625 score, best-offer end of range (6.125%)$101,901
625 score, high-offer end of range (8.875%)$127,688
700 score, best-offer end of range (5.875%)$99,697
700 score, high-offer end of range (8.125%)$120,400

Same illustrative amortization model as the down-payment/rate table above, applied to CFPB's own credit-tier rate ranges at a $400,000 price and 20% down. Not a rate quote.

At the best offer each tier is likely to see, the gap is modest — a couple thousand dollars of annual income. At the high end of each tier's range, where a thinner-file or lower-score borrower is more likely to actually land, the gap widens to several thousand dollars a year. Two buyers with identical income, debt and down payment — but different credit scores — can end up qualifying for meaningfully different maximum purchase prices purely because of where their score lands them in a lender's rate sheet, before a single dollar of income or debt is even considered.

How other debt — student loans especially — changes the math

The back-end ratio caps housing plus every other recurring debt combined, so a dollar of car payment or student loan crowds out a dollar of house exactly the way it would if it were added straight to the mortgage payment. Student loans are the sharpest example because of how lenders are required to treat a loan with no current payment showing on the credit report. Under HUD's Mortgagee Letter 2021-13 (effective for FHA case numbers assigned on or after August 16, 2021), if a student loan reports a $0 monthly payment — common for loans in deferment, forbearance, or an income-driven repayment plan — the lender must still count 0.5% of the outstanding balance as a monthly debt for qualifying purposes, even though the borrower is paying nothing today.

Concretely: a borrower with $60,000 in student loans reporting a $0 payment is underwritten as if they owe $300/month (0.5% × $60,000) — a real, mandatory debt line that eats directly into the 43% back-end ceiling before the front-end housing math even starts. At a 43% back-end limit, that single $300 phantom payment requires roughly $8,400 of additional annual income just to keep the same housing budget available, without the buyer's actual take-home pay changing at all. This is exactly why two applicants who "feel" like they have the same disposable income can qualify for very different loan amounts once their liabilities are run through the lender's actual worksheet rather than their bank-account math.

Why the same salary buys so much more in some states

Incomes vary by state far less than home prices do. The Census Bureau's 2024 American Community Survey put median household income at $109,707 in the District of Columbia (the national high) and at $59,127 in Mississippi (among the lowest, alongside Arkansas, Louisiana and West Virginia) — under a 2x spread nationally, with a national median of $81,604. Home prices, by contrast, commonly vary by 4x or more between the least and most expensive states. Since the required-salary figure is a direct function of price at a fixed ratio and rate, that price gap is what actually drives the "salary needed" gap between states — not a comparable gap in what people earn.

That mismatch is exactly why a state-level or even metro-level figure is more useful than a single national number: the ratio math and the DTI ceiling are the same everywhere, but the home price you're plugging in is not.

Home prices aren't the only regional variable, either — what a given salary is actually worth once you're living there differs too. The Bureau of Economic Analysis's Regional Price Parities put California at 110.7, Hawaii at 110.0, and New Jersey at 108.8 in 2024 (all roughly 9–11% above the national average across goods, housing and services combined), against Arkansas at 86.9 and Mississippi at 87.0 (both roughly 13% below). A required-salary figure calculated the same way in a 110-RPP state and an 87-RPP state isn't apples to apples in real purchasing-power terms even at an identical dollar amount — the nominal salary needed is higher in the expensive state largely because the home price itself is higher, but everything else that salary has to cover (groceries, services, a night out) also costs more once you're there.

Housing specifically swings even harder than the all-goods RPP suggests. BEA's 2024 data puts California's housing-rent RPP at 154.3 (and the District of Columbia at 155.0) against West Virginia's 54.2 — meaning housing costs alone run roughly three times higher in the priciest state than the cheapest, a far wider spread than the ~1.3x gap in overall goods-and-services prices between the same tiers of states. That's the real reason the required-salary figure is so much more volatile across states than the general cost-of-living conversation suggests: it's driven almost entirely by the housing component specifically, not by regional prices in general.

How this page relates to the state pages

This page and the 51 state-level pages linked below run the identical DTI methodology described above — the same ratio math, the same six-step calculation — but with one input swapped: this page uses a single illustrative national price ($415,000) to isolate how down payment, rate, credit score and debt each move the number in a vacuum. Each state page instead plugs in that state's own median home price, so the required-salary figure you see there reflects an actual local market rather than a stand-in number chosen to make the math easy to follow.

In other words: come to this page to understand why the number moves the way it does: down payment, rate, credit score and debt all shift it in specific, calculable directions regardless of which state you're in. Go to your state's page for the number itself, calculated against the price you'd actually be paying.

Frequently asked questions

Where does the 'salary needed to buy a home' number actually come from?+

It's back-calculated from a debt-to-income (DTI) ratio, not a separately invented figure. Lenders cap what share of your gross monthly income can go to housing costs (the front-end ratio) and to all debt combined (the back-end ratio). HUD's own manual underwriting standard for FHA loans is 31% front-end and 43% back-end; conventional lenders commonly use a 28%/36% benchmark. A 'salary needed' calculator picks a ratio, computes the monthly PITI payment at a given price/rate/down payment, and divides by that ratio to back into the required income.

How much does down payment size change the salary I need?+

Substantially, because it changes the loan amount the payment is based on, not just the cash you bring to closing. Going from 3% down to 20% down on the same home price cuts the financed amount by roughly 17.5% of the price, which cuts the P&I payment by close to that much too — often the single largest lever in the required-income figure short of changing the price itself.

How much does the interest rate change the required salary?+

A one-point rate move changes the monthly P&I payment by roughly 10–12% on a 30-year loan, which flows straight through to the required-income figure at the same ratio. That's why the same home price can require a meaningfully different salary in two different rate environments even with an identical down payment — check Freddie Mac's Primary Mortgage Market Survey for the current average rate before relying on any fixed-rate example.

Why does required income vary so much by state?+

Mostly because home prices vary far more across states than incomes do. Median household income ranged from $59,127 (Mississippi) to $109,707 (the District of Columbia) in 2024 per the Census Bureau — under a 2x spread — while median home prices vary by a much wider multiple across the same states, so the DTI math produces a required-income figure that swings far more than incomes actually do.

Does a low credit score really change how much salary I need?+

Yes, because it changes the rate you're quoted before your income is even evaluated. CFPB rate-checker data shows a 625 score quoted 6.125%–8.875% versus 5.875%–8.125% for a 700 score on the same $400,000 purchase — a spread that shifts the monthly payment, and therefore the required-income figure at a fixed DTI ratio, by a few percent on its own.

Do student loans in deferment still count against me if I'm not paying anything?+

Usually yes. Per HUD Mortgagee Letter 2021-13, if your credit report shows a $0 student loan payment, the lender is required to count 0.5% of the outstanding balance as a monthly debt anyway — $300/month on a $60,000 balance, for example — which counts against your back-end DTI ceiling exactly like a real payment would, even though nothing is actually due.

Can I qualify above the standard 31%/43% or 28%/36% ratios?+

Sometimes, with documentation. HUD's manual-underwriting guidance lists specific compensating factors that let an underwriter approve a higher ratio: a down payment of 10% or more, at least three months of documented cash reserves after closing, a minimal increase over the borrower's current housing expense, or demonstrated income not reflected in effective income. None of these change the required-income math itself — they widen how far above that math a specific borrower is allowed to go.

Methodology

DTI ratios (31%/43%, 28%/36%) are drawn directly from HUD's manual-underwriting standard and common conventional-lending practice; the NAR figure (25% at 20% down) is that index's own published methodology, shown for comparison rather than used in the worked example or scenario table. The worked example and scenario table use standard 30-year amortization at a fixed illustrative price and a rough combined tax/insurance estimate — a demonstration of how the inputs move the output, not a published affordability table, and should not be read as a rate quote or a specific state figure. The credit-score comparison is CFPB's own published rate-checker example (Curinos data, April 2025 snapshot), not a live quote. The student-loan example applies HUD ML 2021-13's 0.5%-of-balance rule directly to a round-number balance. Regional income figures are the Census Bureau's 2024 American Community Survey estimates; regional cost-of-living figures are BEA's 2024 Regional Price Parities. This page will be refreshed as Freddie Mac's PMMS average rate moves materially from the illustrative rate used above.
