Quick answers

  • On a $120,000 salary, a common lender guideline (28% of gross income for housing) puts your max monthly housing payment around $2,800.
  • At a 7.18% rate, with about $550/month for taxes and insurance, that supports a loan of roughly $332,000.
  • That works out to a home price of about $369,000 with 10% down or $415,000 with 20% down.
  • Debts, your down payment, local taxes and the rate you get can move these numbers a lot.

A $120,000 salary is well above the U.S. median. So you’d think buying a house would be easy. In a lot of places it is. In others, $120K can feel surprisingly tight once you add taxes, insurance and a mortgage rate above 7%.

Let’s do the math the way a lender would, then talk about how to stretch (or protect) your budget.

Step 1: The lender rules of thumb

Lenders look at two debt-to-income (DTI) ratios:

  • Front-end ratio (housing only): a classic guideline is no more than 28% of gross monthly income.
  • Back-end ratio (all debts): a classic guideline is 36%, though many conventional and FHA loans allow higher, sometimes into the mid-40s or more with strong credit and savings.

On $120,000 a year, your gross monthly income is $10,000. So:

Rule Limit Monthly amount
Housing (28%) Mortgage + taxes + insurance (+ HOA/PMI) $2,800
All debts (36%) Housing + car + student loans + cards $3,600

If you have $400 a month in other debts, the 36% rule leaves $3,200 for housing, so the 28% rule ($2,800) is the tighter limit. If you have $1,000 a month in other debts, the 36% rule leaves only $2,600. Debts matter. Check yours with the DTI calculator and our guide to debt-to-income ratio.

Step 2: Turn the payment into a loan amount

Your $2,800 has to cover more than the loan. In this example, we’ll assume $350/month for property taxes and $200/month for homeowners insurance. That leaves $2,250 for principal and interest.

Example

$2,250/month in principal and interest on a 30-year fixed loan supports about:

  • At 6.50%: a $356,000 loan
  • At 7.18%: a $332,000 loan
  • At 7.50%: a $322,000 loan

Every half-point of rate moves your buying power by roughly $10,000 to $24,000 here.

Step 3: Add your down payment

Rate Price with 10% down Price with 20% down
6.50% ~$395,500 ~$445,000
7.18% ~$369,000 ~$415,000
7.50% ~$357,500 ~$402,000

With less than 20% down on a conventional loan, you’ll usually pay private mortgage insurance, which eats into the $2,800 and lowers these prices a bit. Learn more in what PMI is and how to get rid of it.

Myth buster“Lenders will approve me for X, so I can afford X.” An approval is the most a lender is willing to lend, not what fits your life. Child care, retirement saving, commuting and home repairs don’t show up in DTI. Many people aim below their max on purpose.

Things that change the answer

  • Property taxes: They vary hugely by state and county. A home in a high-tax area can cost several hundred dollars more a month than the same price elsewhere. See property taxes and your mortgage.
  • Insurance: In storm- and wildfire-prone areas, premiums can be far above our $200 estimate. Read homeowners insurance explained.
  • HOA dues: Condos and planned communities often add $100 to $500+ a month, and lenders count them.
  • Your credit score: A better score usually means a lower rate. See the credit score you need for a mortgage.
  • Loan type: FHA, VA and conventional loans have different down payment and insurance rules. Compare FHA, VA and conventional.
Fun factThe “28/36” rule is decades old, but it’s still a handy starting point. Think of it as training wheels, not a speed limit.

How to stretch $120K further

  • Pay down a car loan or card first. Freeing up $300 a month in debt can raise what you qualify for by tens of thousands.
  • Shop several lenders. Even a small rate difference adds up. Compare Loan Estimates side by side.
  • Consider buying down the rate. Mortgage points or a 2-1 buydown can lower early payments.
  • Look for help. Some down payment assistance programs allow incomes at this level, depending on the area.

FAQ

How much house can I afford on $120K a year?

Using the 28% rule and a 7.18% rate, roughly $369,000 with 10% down or $415,000 with 20% down, assuming about $550/month for taxes and insurance and modest other debts.

Is $120K a good salary to buy a house?

In many U.S. areas, yes. In high-cost coastal metros, it may only stretch to a condo or a smaller home, especially with rates above 7%.

Can I go above 28% of my income on housing?

Often yes. Many loan programs allow higher ratios with strong credit and reserves. Just be sure the payment still fits your real budget.

Does a bigger down payment help?

Yes. It raises your price range, lowers your payment and can remove PMI at 20% down on a conventional loan.
