Mortgage Down Payment: How Much Do You Really Need?

What a Down Payment Actually Does

A down payment is the portion of the home price you pay out of pocket at closing. The rest is covered by your mortgage. If you buy a $350,000 house and put down $35,000, you borrow $315,000.

From the lender's perspective, a larger down payment reduces their risk. You start with more equity in the property, which means you are less likely to walk away if the market dips. That reduced risk translates into better loan terms for you: lower interest rates, smaller monthly payments, and fewer fees.

Minimum Down Payment by Loan Type

The minimum varies depending on the loan program you qualify for. Here is what the major options look like in 2026:

These are the minimums set by each program. Individual lenders may require more depending on the property type, your credit history, or the loan amount.

The 20% Rule: Where It Comes From and When It Matters

The 20% figure is not a requirement. It is the threshold at which conventional lenders stop requiring private mortgage insurance (PMI). That is the only reason it gets so much attention.

On a $400,000 home, 20% means $80,000 in cash before closing costs, inspections, and moving expenses. For most first-time buyers, that amount is not realistic without years of aggressive saving or outside help. Waiting to hit 20% can mean years of renting while home prices continue rising.

Putting down less than 20% is a legitimate and common choice. In 2025, the National Association of Realtors reported that the median down payment for first-time buyers was 8%. Repeat buyers averaged 19%. The market has moved well past the idea that 20% is the only responsible option.

How Your Down Payment Affects Monthly Costs

The difference is more concrete than most people expect. Consider a $350,000 home with a 30-year fixed mortgage at 6.5% interest:

The jump from 5% to 20% down saves about $498 per month when you include PMI. Over the first five years, that adds up to roughly $29,880. But it also means tying up an additional $52,500 in cash at closing. Whether that tradeoff makes sense depends on your savings, your timeline, and what else you could do with that money.

Understanding PMI

Private mortgage insurance protects the lender, not you. If you default, PMI covers part of the lender's loss. You pay for it as part of your monthly mortgage payment.

PMI on a conventional loan typically costs between 0.3% and 1.5% of the original loan amount per year. The exact rate depends on your credit score, the loan-to-value ratio, and the insurer. On a $315,000 loan, that works out to roughly $79 to $394 per month.

The good news: PMI on conventional loans is not permanent. Once you reach 20% equity, either through payments or appreciation, you can request removal. Lenders are required to automatically cancel it once you hit 22% equity based on the original purchase price.

FHA loans work differently. If you put less than 10% down on an FHA loan, the mortgage insurance premium (MIP) stays for the entire loan term. With 10% or more down, it drops off after 11 years. This is one reason some buyers start with an FHA loan and refinance into a conventional loan once they have enough equity.

Down Payment Assistance Programs

Most states and many local governments offer down payment assistance (DPA) programs that first-time buyers overlook. These programs take different forms:

• Grants that do not need to be repaid
• Forgivable loans that are written off after you live in the home for a set number of years
• Deferred-payment loans with no monthly payments, due when you sell or refinance
• Matched savings programs that match your contributions dollar-for-dollar up to a cap

Eligibility usually depends on income, location, and whether you have owned a home in the past three years. Some programs define "first-time buyer" broadly enough to include people who previously owned but have not in the last three years.

The U.S. Department of Housing and Urban Development (HUD) maintains a list of state and local programs. Your lender or a HUD-approved housing counselor can help you find what is available in your area.

Practical Tips for Building Your Down Payment

Saving for a down payment is straightforward, but that does not make it easy. A few strategies that consistently work:

• Set a specific target. Calculate the actual dollar amount you need based on your target home price and loan type. A vague goal of "save more" does not create urgency. A goal of "$18,000 by March" does.
• Automate transfers. Set up a recurring transfer to a dedicated savings account on payday. Money you never see in your checking account is money you will not spend.
• Use windfalls intentionally. Tax refunds, bonuses, and side income go further when they have a specific destination. Route them directly into your down payment fund.
• Look at high-yield savings. At current rates, a high-yield savings account can add meaningful interest over 12 to 24 months of saving. The difference between 0.01% and 4.5% on $20,000 over two years is close to $1,800.
• Cut one large expense temporarily. Reducing or pausing a single major recurring cost, like a car payment, subscription, or dining budget, often moves the needle faster than trimming a dozen small ones.

When a Smaller Down Payment Makes Sense

Putting down the absolute minimum is not always the wrong call. There are situations where it is the smarter financial move:

• Home prices are rising faster than you can save. If prices in your market are climbing 5% to 8% per year, waiting another two years to save more could cost you more than PMI ever will.
• You need to keep cash reserves. Draining your savings to hit 20% and then having nothing left for repairs, emergencies, or closing costs puts you in a fragile position.
• You have high-return alternatives for the cash. If you are an experienced investor with a clear use for the capital, the math may favor a smaller down payment and investing the difference. This depends heavily on your risk tolerance and financial discipline.

On the other hand, stretching to a larger down payment makes sense if you want the lowest possible monthly payment, plan to stay in the home long term, or want to avoid the hassle and cost of PMI entirely.

Bottom Line

There is no single right answer for how much to put down. The best down payment is the one that gets you into the right home at a monthly cost you can sustain, without leaving you financially exposed. For some buyers that is 3%. For others it is 20% or more.

Start with your budget, not a rule of thumb. Figure out what you can comfortably afford each month, then work backward to find the down payment that gets you there.
