How Much House Can You Afford on a $70,000 Salary?

"Buy a home for 2-3x your salary" is the advice everyone repeats and almost nobody checks against current mortgage rates. That multiplier made sense when 30-year rates sat near 3.5%. At today's rates, the real number lenders actually use — the 28/36 rule — lands closer to 3.5-4x salary, and it changes meaningfully depending on your down payment and existing debt. Here's the real math on a $70,000 salary, with every assumption shown so you can rerun it for your own number.

The Rule Lenders Actually Use: 28/36

Underwriters size a mortgage around two ratios, not a flat multiple of income. The front-end ratio caps your total housing payment — principal, interest, property tax, and insurance, together called PITI — at roughly 28% of gross monthly income. The back-end ratio caps PITI plus every other debt payment (car loans, student loans, credit cards) at roughly 36% of gross monthly income for conventional loans without strong compensating factors. Whichever ratio is more restrictive for your situation is the one that actually sets your budget.

Running the Numbers on $70,000

A $70,000 salary is $5,833/month gross. At 28%, that's a $1,633/month PITI ceiling. Using a 30-year fixed loan at 6.5% — roughly the middle of where conventional rates have sat for the past couple of years — with 20% down and property tax plus insurance estimated at a combined 1.3% of home value per year (close to the national average), that ceiling supports a home price of about $266,000: a $212,800 loan, a $53,200 down payment, and a monthly payment of roughly $1,346 principal and interest plus $288 taxes and insurance.

That works out to almost exactly 3.8x annual salary under these assumptions, which holds roughly steady across income levels since it's driven by the same rate and ratio:

Why a Smaller Down Payment Doesn't Always Mean More House

The intuitive assumption is that putting less down frees up your budget for a pricier home. Run the numbers and it's often the opposite. Drop to 3.5% down (an FHA-style minimum) on that same $70,000 salary, and mortgage insurance — typically 0.5-1% of the loan per year until you build enough equity to drop it — plus interest on a much larger loan balance eats into the same $1,633 PITI ceiling faster than the smaller down payment expands it. The math lands around a $207,500 max home price at 3.5% down, roughly $58,500 less than the $266,000 you could afford at 20% down — even though the cash required upfront drops from $53,200 to about $7,260.

That's not an argument against low-down-payment loans — for many buyers, having $45,000 more cash on hand is worth a smaller home price ceiling. It's just the tradeoff nobody states plainly: a smaller down payment lowers your entry cost, but it also lowers, not raises, the maximum home price your monthly budget supports. Building the down payment gap with a dedicated savings plan is one direct way to close that $58,500 spread — our Savings Goal Calculator shows how long that takes at different monthly contributions.

When Existing Debt Changes the Math

The 28% front-end number only wins if the 36% back-end number has room left after your other debts. Add a $400/month car payment and a $200/month student loan to the same $70,000 salary, and the back-end ceiling (36% × $5,833 = $2,100) leaves only $1,500/month for PITI instead of $1,633 — the debt, not the income, becomes the binding constraint. That drops max home price to roughly $244,000, about $22,000 lower than the debt-free scenario. Paying down that $600/month in obligations before applying — even partially — directly raises how much home you qualify for, often by more than saving a slightly larger down payment would. Our Debt Payoff Calculator shows how fast that headroom opens up.

How Much the Interest Rate Alone Moves the Number

Rate matters more than almost any other variable in this calculation, which is exactly why "2-3x salary" stopped being reliable advice. The same $70,000 salary, same 28% ceiling, same 20% down, but at 3.5% instead of 6.5%, supports a home price of about $349,000 — roughly 5x salary instead of 3.8x, and $83,000 more house for an identical paycheck. That single variable explains most of the gap between older rules of thumb (written during a decade of sub-4% rates) and what actually pencils out today. It also means a 1-point rate drop on a future refinance can meaningfully expand what a given payment supports, without any change in income.

The Bottom Line

On a $70,000 salary at a realistic 6.5% rate, roughly $266,000 is the ceiling under the standard 28/36 rule with 20% down and no other debt — and every one of those assumptions moves the number meaningfully in either direction. A smaller down payment lowers it, a car payment lowers it, and a lower rate raises it faster than almost anything else. Skip the flat multiplier and run your actual salary, rate, down payment, and debts through the Mortgage Calculator — it takes less time than the rule of thumb takes to be wrong for your situation.
