How to Afford a $300k House

To afford a $300,000 home, you generally need a household income between about $54,000 and $75,000, and far less down payment than most people think. At today's 30-year fixed rate of 6.25% (6.26% APR, verified July 2026), a $300,000 home with 20% down runs about $1,843 a month including taxes and insurance, and low-down-payment loans can get you in for as little as 3% to 3.5% down.

The income you actually need depends on your down payment, your other monthly debts, and how lenders really measure what you can carry. The old idea that you need 20% down and that housing must stay near 28% of your income keeps a lot of qualified buyers renting longer than they need to.

What income do I need to afford a $300k house?

Most buyers need somewhere between $54,000 and $75,000 a year to afford a $300,000 home, depending on down payment and existing debt. The range is wide because it depends on what else you owe each month and how much you put down.

Here is the monthly picture with 20% down, which avoids mortgage insurance:

Cost component	Amount (20% down)
Loan amount	$240,000
Principal and interest	about $1,478/mo
Property taxes (~1.1%)	about $275/mo
Homeowners insurance	about $90/mo
Total payment	about $1,843/mo

To carry that payment plus about $400 in other monthly debts, you would need roughly $75,000 a year at a conservative 36% debt-to-income ratio, about $63,000 at 43%, and about $54,000 at 50%. If you want to test your own income and debts, you can run the numbers in an affordability calculator before you talk to anyone. That spread is exactly why the qualifying rules matter more than the rules of thumb.

Do I really need 20% down for a $300k house?

No. This is the most common myth at this price point, and it keeps people renting for years while they save money they do not actually need. You can buy a $300,000 home with far less down.

FHA loans require just 3.5% down, which is $10,500 on a $300,000 home. Conventional loans allow as little as 3% down for qualified buyers, which is $9,000. Both require mortgage insurance while you are under 20% equity, but that insurance is temporary on a conventional loan and falls away as you build equity. For a lot of first-time buyers, getting in now with 3.5% down and stopping rent beats waiting three years to save a bigger down payment while home prices climb.

Here is how the down payment scenarios compare at 6.25%:

Down payment	Loan amount	Principal & interest	Est. total/mo
5% ($15,000)	$285,000	about $1,755 + PMI	about $2,262
10% ($30,000)	$270,000	about $1,662 + PMI	about $2,162
20% ($60,000)	$240,000	about $1,478	about $1,843

Is the 28% rule the real limit?

No. The 28% guideline is a comfort cushion, not the qualifying ceiling. Conventional loans run through automated underwriting can approve total debt-to-income ratios up to 50% when you have compensating factors like solid credit or cash reserves, which is why the 28% rule isn't the real qualifying limit.

At the $300,000 level this is often the difference between qualifying and not. A buyer earning $58,000 who assumes housing must stay at 28% of income might think they cannot afford it, when in reality, with decent credit, they may qualify comfortably. As a broker who runs files through both Fannie Mae and Freddie Mac automated underwriting across 240-plus wholesale lenders, I regularly see approvals at higher ratios when the rest of the file is strong.

What else do I need besides the down payment?

Beyond the down payment, you need closing costs and a little cushion in reserve. Closing costs on a $300,000 purchase typically run 2% to 5% of the price, so about $6,000 to $15,000, covering lender fees, title, escrow, and prepaid taxes and insurance.

The good news is there is real help at this price. Down payment assistance programs across many states can cover part or all of your down payment and some closing costs, and sellers can contribute toward your closing costs too. Between low-down-payment loans and assistance programs, the cash needed to buy a $300,000 home is often much smaller than buyers expect. I am Emmett Clark, a mortgage broker licensed in 18 states with more than 20 years of experience, and finding the lowest-cash path into a first home is a big part of what I do.

Can I afford a $300k house on one income?

Yes, in many cases. On a single income, you would generally need to earn somewhere in the mid-$50,000s to mid-$70,000s depending on your other debts and down payment, which is a realistic salary for a lot of buyers.

The key levers are keeping your other monthly debts low and choosing the right loan. If a car payment or student loans are eating into your ratios, paying those down or restructuring can free up the room you need. This is worth mapping out with a broker before you shop, and it fits into the bigger guide to buying a home if you want the full picture, because small changes to your debt picture can meaningfully change what you qualify for.
