How much down payment do you really need?
The most common down payment on a home is far below 20%. You can buy a primary residence with as little as 3% down on a conventional loan, 3.5% down on an FHA loan, and nothing at all on a VA or USDA loan if you qualify. The 20% figure that everyone repeats is not a rule for buying a house. It is the point at which a conventional lender stops charging you private mortgage insurance.
Where the 20% number comes from
For decades, 20% down was the standard because it was the line lenders drew between a safe loan and a risky one. A buyer with 20% equity from day one is far less likely to walk away, so the lender does not require extra insurance to cover its risk. That logic still holds, which is why 20% remains the threshold for dropping private mortgage insurance. What changed is that loan programs now let you buy with far less, as long as you accept that insurance or qualify for a program that does not use it.
So the honest way to read 20% is not as the cost of entry. It is one specific milestone: the amount of equity that removes one specific monthly charge. Plenty of buyers purchase with 3% to 5% down and do fine. The question is not whether you are allowed to. It is what the lower number costs you over time.
What each loan type requires
The minimum down payment depends entirely on the loan, and the gaps are large. Here is what the main programs ask for on a primary home, and what each one does about mortgage insurance.
| Loan type | Minimum down | Mortgage insurance | Who it fits |
|---|---|---|---|
| Conventional | 3% | Private mortgage insurance until 20% equity | Buyers with solid credit and a low down payment |
| FHA | 3.5% | Mortgage insurance, often for the life of the loan | Lower credit scores or smaller savings |
| VA | 0% | None, a one-time funding fee instead | Eligible veterans and service members |
| USDA | 0% | An annual guarantee fee | Eligible buyers in qualifying rural and suburban areas |
| Conventional, 20% down | 20% | None | Buyers who want to avoid mortgage insurance |
| Jumbo | 10% to 20% | Varies by lender | Loans above the conforming limit |
Two rows in that table matter most. First, the 0% options, VA and USDA, are real and they are not fringe programs, but they are limited to buyers who meet specific eligibility: military service for VA, and location and income limits for USDA. Second, the difference between FHA and conventional insurance is not small. Conventional private mortgage insurance falls off once you reach 20% equity, while FHA mortgage insurance often stays for the life of the loan unless you refinance into a different program.
What a small down payment costs you
Putting less money down is not free, and the cost shows up in three places. You borrow more, so you pay interest on a larger balance for the life of the loan. You pay mortgage insurance until you reach the equity threshold, which on a conventional loan can run a few hundred dollars a month. And you start with less equity, which matters if you need to sell or refinance before the market moves in your favor.
Here is the trade in plain numbers. On a $400,000 home, 3% down is $12,000 and 20% down is $80,000. The buyer who puts down 3% keeps $68,000 in cash but carries a larger loan and pays private mortgage insurance until the balance falls far enough. The buyer who puts down 20% has a smaller payment and no insurance, but has tied up a large amount of cash in the house. Neither is wrong. They are different bets on what that cash is worth to you somewhere else.
When putting more down is worth it
More money down makes the most sense when the monthly payment is the thing you are trying to control, when you want to avoid mortgage insurance entirely, or when a competitive market rewards a stronger offer. A larger down payment lowers the loan, lowers the payment, and signals to a seller that the financing is solid. In a market with multiple offers, that signal can matter as much as the price itself.
Keeping cash makes more sense when your reserves are thin, when you carry higher-interest debt to clear first, or when the money does more for you invested or held as a safety net than it saves you in mortgage insurance. The rule of thumb is simple: do not drain your emergency fund to reach 20%. The insurance you avoid is rarely worth the risk of having no cushion the month something breaks.
How much cash you need beyond the down payment
The down payment is not the whole bill. Closing costs usually run 2% to 5% of the price, covering lender fees, title, taxes, and prepaid insurance. On that same $400,000 home, that is roughly $8,000 to $20,000 on top of the down payment. You will also want a reserve for moving, immediate repairs, and the first few months of ownership, because the first months are when surprises tend to appear. A realistic plan budgets the down payment, the closing costs, and a cushion, not the down payment alone.
One piece that is easy to miss: the down payment is a percentage of the price, so the price itself drives every number in the plan. The more defensible that price is, the more confident the whole calculation becomes. A home priced above what the comparable sales support inflates your down payment, your loan, and your monthly cost all at once, which is why understanding the real value of a home before you commit is part of the financial picture, not separate from it.
Is a 20% down payment required to buy a house?
No. 20% is the point at which a conventional lender stops charging private mortgage insurance, not a requirement to buy. Conventional loans go as low as 3% down, FHA loans 3.5%, and VA and USDA loans 0% for buyers who qualify.
What is the lowest down payment you can make?
For a primary home, 0% with a VA or USDA loan if you are eligible, otherwise 3% on a conventional loan or 3.5% on an FHA loan. Second homes and investment properties require more, usually 10% to 25%.
How much money do you need beyond the down payment?
Plan for closing costs of roughly 2% to 5% of the price, plus a cash reserve for moving and the first months of ownership. A 3% down payment on a $400,000 home is $12,000, but the total cash needed to close is usually several thousand dollars more.
