How Much Down Payment Do You Really Need?

Last updated August 24, 2026

"You need 20% down" is the most expensive myth in housing. You don't — and knowing the real minimums, plus what 20% actually buys you, can get you in the door years sooner.

The real minimums

Twenty percent is not a requirement; it's a threshold that lets you skip mortgage insurance. The actual floors are much lower:

Conventional: as little as 3% down for many buyers.
FHA: 3.5% down with a qualifying credit score.
VA and USDA: 0% down for those who qualify.

See loan types compared for who fits which.

On a $400,000 home	Cash down	Loan	PMI?
3% down (conventional)	$12,000	$388,000	Yes
10% down	$40,000	$360,000	Yes
20% down	$80,000	$320,000	No

What more money down actually buys

Below 20% on a conventional loan you'll pay PMI until you reach 20% equity. Putting more down also lowers your loan-to-value, which can earn a better rate, and it shrinks the loan itself. So a bigger down payment is a genuine trade-off — less interest and no PMI versus tying up cash — not a rule handed down from on high.

Gift funds are allowed

Family can help. Most loan programs let a relative gift some or all of your down payment, provided it's a true gift — not a loan — documented with a donor letter and a clear paper trail showing where the money came from and that it landed in your account. Lenders verify this carefully, so plan the transfer early rather than days before closing.

Don't drain your cushion

Lenders like to see reserves left over after you close, and life is easier with them too. A slightly smaller down payment that keeps a few months of expenses in the bank often beats an all-in payment that leaves you cash-poor the day you get the keys.

Don't argue 3% vs. 20% in the abstract — run both. Weigh the PMI cost and slightly higher rate at 3% against the opportunity cost of parking cash to reach 20%. Sometimes buying sooner wins; sometimes waiting to hit 20% does. The calculator makes the difference concrete.

Common questions

Do I really need 20% down to buy a house?

No. Twenty percent is the threshold that lets you skip mortgage insurance, not a requirement. Conventional loans start near 3% down, FHA at 3.5%, and VA and USDA at 0% for those who qualify.

What does putting 20% down actually get me?

No PMI, a lower loan-to-value that can earn a better rate, and a smaller loan overall. It's a genuine trade-off against tying up cash — not a rule you have to meet.

Can I use gift money for my down payment?

Most programs allow a gift from a relative if it's a true gift, not a loan — documented with a donor letter and a clear paper trail. Plan the transfer early, because lenders verify it carefully.

Is a bigger down payment always better?

Not if it drains your cushion. Lenders like to see reserves left after closing, and a slightly smaller down payment that keeps a few months of expenses in the bank often beats going all-in.
