How Much Down Payment Do You Actually Need?

The 20% Myth

Somewhere along the way, “20% down” hardened from a guideline into folklore, and that folklore keeps renters renting for years longer than they need to.

Here is the actual rule. Twenty percent down is the point where a conventional loan stops requiring private mortgage insurance. That is all it is. It was never the price of admission. The real minimums run from 3% down to nothing at all, depending on the program:

• Conventional (HomeReady / Home Possible): 3% down. Fannie Mae and Freddie Mac programs for borrowers earning up to 80% of area median income.
• FHA: 3.5% down with a credit score of 580 or higher, per HUD.
• VA: zero down for eligible veterans, service members, and certain surviving spouses.
• USDA: zero down in eligible rural and suburban areas, within income limits.

On a $350,000 house, the folklore says save $70,000. The 3% programs say $10,500. That difference is years of saving, and home prices are not waiting for you.

What Putting Less Down Costs You

Nothing is free, so name the costs honestly. Put down less than 20% on a conventional loan and you pay PMI. Freddie Mac pegs it at roughly $30 to $70 a month per $100,000 borrowed, with your credit score deciding where in the range you land. On a $300,000 loan, call it $90 to $210 a month.

That sounds like pure waste. It often is not. PMI is the fee that lets you buy now instead of in 2031, and it is temporary: conventional PMI cancels once you build equity, and rising home values can shorten the clock. A smaller down payment also means a bigger loan and a bigger monthly payment, so run the full number, not just the sticker.

FHA’s version of mortgage insurance is costlier by structure: 1.75% upfront plus an annual premium that, on a minimum-down loan, lasts for the life of the loan. VA loans charge a one-time funding fee instead of monthly insurance. USDA charges 1% upfront and 0.35% a year. Every low-down path has a meter running. The meters just run at different speeds.

Where the Money Can Come From

Your down payment does not have to be money you ground out of your paycheck. Per Fannie Mae, HomeReady down payments can come entirely from gifts, grants, and down payment assistance programs, with no minimum contribution from your own funds on one-unit homes. Freddie Mac’s Home Possible works the same way. FHA also allows family gift funds.

Three sources buyers overlook:

• Family gifts. Allowed broadly, but the lender wants a gift letter saying it is not a secret loan. Get the paperwork right.
• State and local assistance programs. Many states run grant or second-loan programs for first-time buyers. Ask every lender you talk to which programs they work with. The answer separates lenders who do this daily from lenders who do not.
• Seller concessions. These cover closing costs rather than the down payment itself, but freeing up cash you had earmarked for closing puts it back in your down payment pile.

The Right Number for You

Forget folklore in both directions. The strongest position is not “maximum possible down.” It is the down payment that leaves you with reserves.

A new house bills you immediately: repairs, furniture, moving, the water heater that read the closing date. A buyer who put 10% down and kept $20,000 in savings is in far better shape than one who scraped to 20% and kept nothing. Lenders look for reserves for a reason. You should too.

Work it backward. Decide how much cash must stay in the bank after closing. Subtract closing costs, typically 2% to 5% of the price. What is left is your down payment budget, and the program menu above tells you what it buys.

Do This Next

Check whether your income qualifies for HomeReady or Home Possible (80% of area median income; the Fannie and Freddie sites have lookup tools). If you served, confirm VA eligibility before looking at anything else. Then get quotes at two different down payment levels from at least three lenders and stack the total monthly costs side by side with our mortgage calculator.
