3% vs. 5% vs. 10% Down: What Changes in Your Payment and Cash to Close?

What each down payment level buys you

These are typical program starting points, not universal cutoffs and not a promise of eligibility. Programs and guidelines change and vary by state, lender, and borrower.

• 3% down: a common low-down-payment conventional starting point, often aimed at first-time buyers. FHA loans frequently start at 3.5% down. At 3%, mortgage insurance typically applies on a conventional loan.
• 5% down: another common conventional starting point. It keeps your cash outlay modest and still leaves most of the purchase financed, so PMI typically applies below 20%.
• 10% down: lowers the loan amount meaningfully, which lowers your monthly payment and the interest you pay over time. It can reduce or avoid some costs, though on a conventional loan PMI may still apply until you reach 20% equity.

Your actual starting point depends on your credit profile, the state the property is in, and the lender's current guidelines. The guide on how much money you need to buy a home walks through the full cash picture.

How the loan size drives your payment

Your monthly principal and interest payment is calculated on the amount you borrow, not the price of the home. Put more down and you borrow less, so your monthly payment is lower at the same rate. Put less down and you borrow more, so the payment is higher and you pay more total interest over the life of the loan. That is the core tradeoff, and it is why the same house can come with noticeably different payments depending on your down payment.

The guide on what affects your monthly payment explains every piece that goes into the number, from principal and interest to taxes, insurance, and HOA dues.

Cash to close is more than the down payment

The down payment is the biggest single check at closing, but it is not the only one. Cash to close also includes closing costs, prepaids, and reserves. Closing costs cover lender fees, title work, and third-party services. Prepaids include things like property taxes and homeowners insurance paid in advance. Reserves are a cushion lenders often want to see after closing. So a 3% down payment on a $375,000 home is $11,250, but the cash you actually bring to the table is higher once those other pieces are added. That is why a lower down payment can still leave you needing a solid cash plan.

When mortgage insurance appears

Mortgage insurance protects the lender, not you, if you stop making payments. On a conventional loan with less than 20% down, private mortgage insurance, or PMI, is typically added to your monthly payment until you build enough equity, often around 20% of the home's value. FHA loans work differently: they carry their own mortgage insurance premium, called MIP, which is built into the loan and often stays for the life of the loan on many programs.

In plain terms, PMI and MIP are an added monthly cost on lower-down-payment scenarios. The exact premium varies by loan program, credit profile, and loan-to-value, so it is not a fixed number you can assume. The examples below note where mortgage insurance typically applies, but the dollar amount is confirmed at application. The Freddie Mac guide to down payments and PMI explains the mechanics in plain language.

Side by side: $375,000 home at 3%, 5%, and 10% down

Numbers are easier to feel side by side. This table is an illustration for planning, not a quote and not an offer of credit. The rate is illustrative: 6.5%, for example only. Rates change and are set at application. Every assumption is listed below the table.

The tradeoff: a smaller payment vs more cash in your pocket

This is the real decision. A larger down payment gives you a lower monthly payment and less interest over time, but it ties up more cash in the home. A smaller down payment keeps more cash liquid for closing costs, repairs, and the reserve cushion lenders and careful buyers both want, in exchange for a higher payment and, on a conventional loan, mortgage insurance until equity builds.

There is no single right percentage. The right number balances your monthly payment, mortgage insurance, equity, and the cash you want to keep, which is exactly what Kladi runs with you in a short conversation. If you are comparing offers, the guide on comparing two Loan Estimates shows how to read the real numbers side by side.

Key takeaways

• 3% and 5% are common low-down-payment conventional starting points; 10% lowers the loan amount and can reduce or avoid some costs.
• A bigger down payment means a smaller loan, a lower monthly payment, and less interest over time, but more cash tied up at closing.
• Cash to close is more than the down payment: closing costs, prepaids, and reserves all add to the cash you bring.
• Mortgage insurance typically applies on lower-down-payment scenarios, and the premium depends on program, credit, and loan-to-value.

Frequently asked questions

Can I combine down payment assistance with a low down payment?

In some states and programs, yes. Down payment assistance can pair with a low down payment to reduce the cash you bring, and gift funds from family are often allowed too. Whether it works for you depends on the state the property is in, the program, and the lender's guidelines, so it is worth confirming before you count on it.

Does more down always mean a better deal?

Not always. A larger down payment lowers your payment and interest, but it also ties up cash you might need for closing costs, repairs, or a reserve cushion. If a big down payment leaves you stretched, a smaller one with a slightly higher payment can be the smarter, more comfortable choice. The best deal is the one that fits your budget and your goals, not just the lowest payment on paper.

Is 10% down enough to avoid mortgage insurance?

On a conventional loan, mortgage insurance typically applies until you reach about 20% equity, so 10% down may still carry PMI, though a smaller premium than at 3% or 5% in many cases. Some programs and lender options can handle this differently, so the exact answer depends on the program, your credit, and your lender.
