The “20 percent down” rule is one of the most persistent myths in personal finance. It kept a generation of buyers on the sidelines waiting to save an amount that kept growing as home prices rose. The truth is more nuanced: the minimum down payment you need depends on the loan type, and the optimal down payment depends on your specific financial situation — not a rule of thumb.
This guide explains the actual minimum down payment requirements for each major loan type, what private mortgage insurance (PMI) costs and how to get rid of it, how a larger down payment affects your monthly payment and total interest, and when putting less down actually makes sense. You will leave with a clear framework for deciding how much to put down on your specific home purchase.
Minimum Down Payment by Loan Type
The minimum down payment is not a universal number — it varies by the type of mortgage you use. Most buyers qualify for more loan types than they realize, and choosing the right one can significantly reduce how much cash you need at closing.
| Loan Type | Minimum Down Payment | Key Requirement |
|---|---|---|
| Conventional (Fannie/Freddie) | 3% | Good credit (typically 620+) |
| FHA Loan | 3.5% (with 580+ credit) | 10% if credit score 500–579 |
| VA Loan | 0% | Eligible military service or surviving spouse |
| USDA Loan | 0% | Rural/suburban property, income limits apply |
| Jumbo Loan | 10–20%+ (varies by lender) | Loan above conforming limit, strong credit |
| Conventional (avoid PMI) | 20% | No PMI, any credit score that qualifies |
Conventional loans backed by Fannie Mae and Freddie Mac allow as little as 3% down for qualified first-time buyers or borrowers meeting income limits. These programs — called HomeReady and Home Possible respectively — come with competitive rates and the ability to cancel PMI once you reach 20% equity. The CFPB’s loan options guide explains the differences between each type in plain language.
FHA loans from the Federal Housing Administration are particularly useful for buyers with credit scores below 700. The 3.5% minimum applies if your score is 580 or above. The trade-off is that FHA loans carry both an upfront mortgage insurance premium (typically 1.75% of the loan, rolled into the loan) and an annual premium, and the annual premium cannot be canceled on most FHA loans originated after 2013 — it lasts the life of the loan unless you refinance. HUD’s loan resource center details current FHA requirements.
VA and USDA loans are genuinely zero-down options for those who qualify. VA loans for eligible veterans, active-duty service members, and qualifying surviving spouses are among the most borrower-friendly mortgage products available — no down payment, no PMI, and competitive rates. USDA loans serve buyers in eligible rural and suburban areas with moderate incomes. Both programs have funding fees or guarantee fees, but these can be rolled into the loan.
What PMI Actually Costs You
Private mortgage insurance (PMI) is the cost you pay when you put less than 20% down on a conventional loan. It protects the lender — not you — if you default. Understanding what it actually costs is essential to deciding how much to put down.
PMI premiums vary based on your credit score, loan-to-value ratio, and loan type, but a common range is roughly 0.5% to 1.5% of your original loan amount per year. On a $350,000 loan, that works out to roughly $1,750 to $5,250 per year, or about $146 to $438 per month added to your payment. That is real money — but it is not permanent.
Under the Homeowners Protection Act, lenders must automatically cancel PMI when your loan balance reaches 78% of the original purchase price, based on your scheduled payments. You can request cancellation earlier — once you hit 80% loan-to-value through a combination of payments and appreciation — by contacting your servicer and, in some cases, ordering a new appraisal. The CFPB explains the PMI cancellation rules in detail. For a deeper look at removing PMI, see the related article linked below.
The key insight: PMI is a temporary cost, not a permanent one. Whether it makes sense to pay PMI while putting less down depends on how long it will take to reach 20% equity and what you would do with the cash you are not putting toward the down payment.
How Down Payment Size Affects Your Loan
A larger down payment affects your mortgage in several interconnected ways. Most are positive, but the opportunity cost is real and worth calculating honestly.
Monthly payment: Every additional dollar of down payment reduces your loan balance and therefore your monthly principal and interest payment. On a $400,000 home, the difference between 5% down ($380,000 loan) and 20% down ($320,000 loan) at the same rate is roughly $385 per month in principal and interest — plus you eliminate PMI.
Interest rate: Putting more down can sometimes qualify you for a slightly better interest rate, particularly if a larger down payment pushes your loan-to-value ratio below a pricing threshold (commonly 75% LTV). Ask your lender to show you the rate at multiple down payment levels.
Loan-to-value and approval odds: A lower LTV makes you a less risky borrower. If your credit profile is borderline, a larger down payment can be the factor that gets you approved or secures a better rate tier.
Opportunity cost: Cash used for a down payment is cash not invested elsewhere. If putting an extra $40,000 into your down payment means depleting your emergency fund or forgoing 401(k) contributions for years, the higher payment reduces risk in one area while increasing it elsewhere. This trade-off is often underweighted by first-time buyers.
Down Payment Assistance Programs
Down payment assistance (DPA) programs are widely available and widely overlooked. These are grants, forgivable loans, and low-interest second mortgages offered by state housing finance agencies, local governments, nonprofits, and some employers to help buyers cover down payment and closing costs.
Eligibility requirements vary by program but commonly include income limits (often tied to area median income), purchase price limits, first-time buyer status (which many programs define as not having owned a home in the past three years), and completion of a homebuyer education course. Many programs also require you to stay in the home for a set number of years or the assistance must be repaid — understand the terms before you commit.
HUD’s website maintains a directory of state-by-state housing finance resources. Your state’s housing finance agency is the single best starting point for finding programs in your area — search for “[your state] housing finance agency” to find the official site. HUD’s homebuying assistance page also links to local resources. These programs can reduce or eliminate the cash you need to close — it is worth spending an hour researching what is available before you assume you need to save more.
When Putting Less Down Makes Sense
There are legitimate scenarios where a lower down payment is the smarter financial move — not just a compromise forced by lack of savings.
- Your emergency fund is thin. Depleting your liquid savings to reach 20% down leaves you financially exposed from day one of homeownership. A furnace replacement, a roof repair, or a job disruption in month three is far more dangerous without a financial cushion. Most financial planners recommend keeping three to six months of expenses liquid even after closing.
- You have high-interest debt. Paying off debt at 18% interest is a guaranteed return that beats any benefit from a larger mortgage down payment.
- You are using a VA or USDA loan. Zero down with no PMI is a genuinely superior product for those who qualify. There is no financial reason to put more down than required with these loans unless you are trying to lower your funding fee.
- Home values are rising rapidly in your market. In a fast-appreciating market, getting into a home sooner — even with a smaller down payment — can mean building equity faster through appreciation. This is market-specific and not guaranteed.
- You have strong investment returns available. If you have reliable access to tax-advantaged investing (401(k) match, Roth IRA) that you are not maximizing, the guaranteed match or tax benefit may outweigh the cost of PMI.
None of these situations means you should put down as little as possible reflexively. They mean the decision deserves real analysis rather than defaulting to “save until you have 20%.”
How to Decide Your Number
A practical framework for choosing your down payment starts with three questions. First, what is the minimum you need to use the loan type you want — and can you get there without depleting your emergency fund or retirement savings? Second, how much would PMI cost on your target loan amount, and how long would you pay it? Third, what would you do with the cash if you did not put it toward the down payment — pay off debt, invest, hold as an emergency reserve?
Work through those three questions with your actual numbers. Then get pre-approval quotes from at least two lenders at different down payment levels to see how rates and PMI costs change. Many buyers discover that the financial difference between 10% down and 20% down — after accounting for PMI costs and investment opportunity cost — is much smaller than they expected.
The goal is not to minimize your down payment or maximize it. The goal is to buy a home you can afford, keep a financial cushion, and not sacrifice other pillars of your financial foundation — retirement savings, debt payoff, emergency reserves — to reach an arbitrary down payment milestone that may not be necessary in your situation.
Down payment decisions are among the most consequential of any home purchase, but they do not have to be paralyzing. Start with the loan types you qualify for, price out the PMI cost if applicable, and make a deliberate choice based on your full financial picture — not a rule of thumb designed for someone else’s situation.
