Buying an average home in America is no longer an average person's purchase. To qualify for a mortgage on a median-priced existing home in mid 2025, a buyer needed an income of roughly $111,000, according to the National Association of Realtors. A decade ago that number was far lower, and the gap is not because homes got twice as nice. It is because two things moved against buyers at the same time.
Prices climbed, and then interest rates climbed on top of them. Either one alone stings. Together they reset what it takes to walk in the door, which is why a household earning a perfectly good salary can suddenly find the math impossible.
How much income do you need to buy a house?
It depends on the price, your down payment, and above all the interest rate. With the median existing home hovering around $435,000 and a 30 year rate near 6.9 percent, NAR pegged the qualifying income at about $111,000 in June 2025. Builders tell a similar story from the other side: an NAHB analysis found that roughly three in four US households could not afford a median-priced new home in 2025.
The rate is the quiet villain here. The chart below shows the monthly principal and interest on a $435,000 home with 20 percent down, at three different rates. The jump from 3 percent to 7 percent adds hundreds of dollars a month for the exact same house.
Model: principal and interest only, on a $348,000 loan. Taxes and insurance add more.
- 3%: $1,467
- 5%: $1,868
- 7%: $2,315
Why the rate matters more than the price
People fixate on the sticker price, but over a 30 year loan the interest rate often moves the payment more than a modest change in price does. A one point rate increase can raise the monthly payment by roughly ten percent, which is why a market can feel unaffordable even when prices dip slightly, if rates rose at the same time.
It also means timing and rate shopping are worth real money. A fraction of a percent, locked for three decades, adds up to tens of thousands of dollars. Run your own price, down payment, and rate through the mortgage calculator and watch how much the rate line alone moves the total.
What can you actually do about it?
You cannot fix the market, but you can change the inputs you control:
- Shop the rate hard. Several lenders, and a locked quote, can beat the first offer by enough to matter for 30 years.
- Weigh a larger down payment against keeping an emergency fund. Twenty percent down avoids private mortgage insurance, but do not drain your cash cushion to get there.
- Look at total monthly cost, not just principal and interest. Property tax and insurance can add several hundred dollars a month.
- Be honest about the rest of your budget. A payment you can technically qualify for is not always one you can comfortably live with.
The bottom line
It now takes an income around $110,000 to buy the median existing home, and roughly three in four households cannot afford a median-priced new one. The culprit is prices and interest rates rising together, with the rate doing more of the damage than most buyers realize. Run your real numbers before you fall for a listing, focus on the rate and the all-in monthly cost, and remember that qualifying for a payment and thriving under one are two different things.
