How much down payment do you actually need?

"20% down" is one of the most repeated numbers in personal finance, and it's also one of the most misleading. It's a threshold that avoids mortgage insurance — not a rule you have to clear to buy a house. Most first-time buyers put down far less, and the real question isn't "do I have 20%," it's "where can the down payment I actually need come from."

We've already run the full dollar-by-dollar math on 20% vs. 5% vs. 3.5% down elsewhere — see the down payment comparison in the main guide for exactly how those percentages change your home price and monthly payment. This page covers what that one doesn't: the minimums by loan type, and the three legitimate ways to close the gap between your savings and your down payment.

Minimum down payment by loan type

Notice that 20% doesn't appear as a minimum anywhere on this list. It shows up because it eliminates PMI on conventional loans, not because any program requires it.

Where the money can legitimately come from

Most people assume a down payment has to come entirely from their own savings. It doesn't. Lenders recognize several other sources — you just need to document them correctly.

Gift funds

Family members can gift you part or all of your down payment. FHA and VA loans allow the entire down payment to be a gift. Conventional loans generally allow it too for a primary residence, though some programs require the borrower to contribute a small amount of their own funds if it's a second home or investment property.

The catch isn't eligibility, it's paperwork. Every lender will require a signed gift letter stating the money is a gift, not a loan that needs repayment, plus a paper trail — typically a bank statement showing the funds leaving the donor's account and landing in yours. Skip the paper trail and the lender can't count the money, even if it's genuinely a gift.

Down payment assistance programs

Most states, and many cities and counties, run down payment assistance (DPA) programs through a state or local housing finance agency. These typically come in one of three forms:

• Outright grants — money you never repay, though some require you to stay in the home for a minimum period.
• Forgivable second loans — a loan that's forgiven gradually, often over 5-10 years, as long as you stay in the home.
• Low or zero-interest second loans — repaid alongside or after your primary mortgage, sometimes deferred until you sell or refinance.

Eligibility usually depends on household income limits, purchase price limits, being a first-time buyer (often defined loosely as not having owned a home in the past three years, not literally "ever"), and completing a homebuyer education course — usually a short online class, not a barrier worth avoiding the program over. Programs and dollar amounts vary a lot by location, so this is a "ask your lender or search your state housing finance agency" conversation rather than a number we can give you here.

Seller concessions

A seller can agree to pay part of your closing costs as part of the negotiated deal — common in slower markets or when a seller wants a clean, fast close. Concessions cannot be used toward the down payment itself, only closing costs and prepaids, and they're capped as a percentage of purchase price:

These caps shift based on occupancy and loan program specifics, so confirm the exact number with your lender before writing an offer that assumes a specific concession amount.

So how much do you actually need?

The honest answer is: enough for the minimum your loan program requires, plus a cushion — not 20%, and not the absolute rock-bottom minimum either. Two considerations matter more than hitting a round percentage:

• Reserves after closing. Putting every available dollar into the down payment and closing with $200 in your account is a real risk, not a badge of honor. Most lenders like to see some reserves left over, and you should too.
• Mortgage insurance cost vs. cash tied up. PMI or MIP is a real monthly cost, but it's often smaller than what you'd give up — in flexibility, in reserves, in time to close — by delaying a purchase to save an extra 10-15% down. Run the actual numbers for your situation rather than assuming more down payment is automatically the better move.

Mistakes that cost buyers money or time here

• Moving gift money without a paper trail. A cash gift with no documented transfer can't be counted by underwriting — get the gift letter and bank documentation sorted before you need it, not during underwriting.
• Assuming you don't qualify for assistance programs. Income limits on DPA programs are often higher than people expect, especially in higher-cost areas. It's worth five minutes to check before ruling it out.
• Negotiating a purchase price assuming seller concessions on top, without confirming the cap. If your loan program caps concessions below what you assumed, the deal's math can fall apart late in the process.
• Draining every account to maximize the down payment. A bigger down payment that leaves you with no emergency fund is a worse financial position than a smaller down payment with reserves intact.
