How Much House Can I Afford on a $90,000 Salary?

$90,000 a year sits right at the edge of what most people call comfortable affordability. The lender math supports a home between $369,159 with 10% down and $415,303 with 20% down, at a housing payment of $2,100 a month. The harder question isn't whether you qualify for that number, it's whether buying right up to it is actually the smart move, or whether you'd come out ahead buying a bit below max and putting the difference to work elsewhere.

The 28/36 math on $90,000

At $90,000 a year, gross monthly income is $7,500. The 28% housing cap puts your monthly payment ceiling at $2,100, and the 36% total debt cap allows up to $2,700 across everything you owe, mortgage included. At a 6.5% rate on a 30-year fixed loan, $2,100 a month in principal and interest supports a loan of about $332,243. Layer a down payment on top: 10% down lands you at $369,159, and 20% down stretches that to $415,303, both because the loan can be slightly bigger and because a 20% deposit removes mortgage insurance from the monthly cost.

What that range buys

Between $369,000 and $415,000 covers a comfortable single-family home in the majority of US metros, often with room for a home office or a slightly larger lot than the entry-level market offers. In expensive coastal cities that budget still buys well, but it's competing hard against a smaller pool of listings.

Buy at the max, or buy below it and invest the rest

Here's the tradeoff worth sitting with: buying at $415,303 maximizes house size and location today, but it also maximizes your monthly payment and reduces the cash you have available for anything else. Buying at, say, $350,000 instead frees up a few hundred dollars a month plus a chunk of the down payment you'd otherwise have committed to a pricier home. Put that difference into a taxable brokerage account or retirement fund and let compound growth work on it for a few decades, and the smaller-house-plus-investing path can outperform the bigger-house path financially, even though it feels like "settling" at the time of purchase. Run the two scenarios side by side with our compound interest calculator before deciding, since the gap between the two paths grows a lot over 20 or 30 years.

Why PITI matters more than the loan payment alone

The $2,100 figure from the 28% rule is meant to cover PITI, principal, interest, taxes and insurance, not just the loan repayment. Property taxes typically run 0.5% to 2% of home value a year depending on the state, which on a $400,000 home could mean $167 to $667 a month on their own. Homeowners insurance adds another $100 to $250 a month in most markets. If you plug only the loan payment into your budget and forget taxes and insurance, you can end up house-poor even while technically staying inside the lender's approval. Always work backward from the full PITI number, not just principal and interest, to find your real affordable price.

How $90,000 stacks up against nearby incomes

At $80,000, the housing ceiling is $1,867 a month and the range tops out near $369,000. At $100,000, that ceiling rises to roughly $2,333 and the range extends past $460,000. $90,000 sits right in between, close enough to the next bracket that a modest raise or a side income stream can meaningfully change what's on the table within a year or two.

The bottom line

On $90,000 a year, the lender math supports a home priced between $369,159 and $415,303, with a monthly payment near $2,100. Before locking in the top of that range, run the PITI numbers for your actual property taxes and insurance costs, and seriously weigh whether buying a notch below your max and investing the gap gets you further over the next decade than stretching for the biggest house the bank will approve.
