Do You Really Need 20% Down to Buy a Home?

Where the 20% rule comes from

The 20% figure is a rule of thumb, not a requirement that applies to every loan. It comes from conventional mortgage practice. For decades, lenders have treated 20% as the point where a borrower's own money covers enough of the risk, so a conventional loan with less than 20% down typically requires private mortgage insurance, or PMI. PMI protects the lender, not you, if you stop making payments.

Because 20% down avoids PMI on a conventional loan, the number became shorthand for a straightforward purchase without mortgage insurance. The CFPB explains how your down payment affects your loan terms, and Freddie Mac covers down payments and PMI directly. The rule is a useful benchmark, but buying with less is common and completely normal in most programs.

Down payment minimums by program

The numbers below 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. Here is where the common programs usually start:

• Conventional loans: often 3% or 5% down, depending on the program and your credit profile. Loans at 3% often target first-time buyers; 5% is a common starting point overall. Below 20%, PMI typically applies.
• FHA loans: often 3.5% down for borrowers who qualify, with FHA's own mortgage insurance built into the loan.
• VA loans: often 0% down for eligible veterans, service members, and qualifying spouses, with a funding fee in many cases.
• USDA loans: often 0% down for eligible buyers in qualifying rural areas, with a guarantee fee.

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, and Kladi confirms what applies to your situation.

What changes with a smaller down payment

• A higher loan amount. You borrow more, so you pay more interest over the life of the loan. The example below shows the scale.
• Mortgage insurance. On a conventional loan with less than 20% down, PMI is typically added to your monthly payment until you build enough equity.
• Less equity on day one. You own a smaller share of the home at closing, which matters if you sell in the early years or refinance before equity builds.
• More cash still in your pocket. Less money tied up in the home means more available for closing costs, repairs, and reserves.

What changes when you put 20% down

• No PMI on a conventional loan. That is one monthly cost that simply is not in your payment.
• More equity from the start. You own 20% of the home at closing, so you are further ahead on the balance from day one.
• A lower monthly payment. A smaller loan amount means less principal and interest each month, even at the same rate.
• A stronger offer, often. A larger down payment signals less financing risk to a seller, which can help when offers are compared, though price, terms, and timing matter too, and nothing guarantees an accepted offer.

The tradeoff: cash in the home vs cash in your pocket

Twenty percent down is not automatically the smartest move, and here is why: it is a lot of cash. On a $350,000 home, 20% is $70,000. If most of your savings goes into the down payment, you can be left with little for closing costs, the repairs a new home always seems to need, or the reserve cushion lenders and careful buyers both want.

Putting less down keeps more cash liquid, which can make sense early in your career, when you have other plans for the money, or when you simply want breathing room in year one. This is the opportunity cost question: every dollar in the home is a dollar not available for something else. 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.

Numbers are easier to feel side by side. This example is an illustration for planning, not a quote, and not an offer of credit. Every assumption is listed below the boxes, and the rate is illustrative, which means it is for example only, not today's market and not your rate.

Key takeaways

• 20% down is a benchmark, not a requirement. Many programs start at 3%, 3.5%, or even 0% for eligible borrowers.
• A smaller down payment usually means a higher payment, and PMI on a conventional loan, until equity builds.
• 20% down avoids PMI on a conventional loan, gives you more equity at closing, and can strengthen an offer.
• The right down payment is the one that leaves you with a payment, a plan, and a cash cushion you can actually live with.

Frequently asked questions

Does putting 20% down help you win the house?

It can help, though nothing guarantees an accepted offer. A larger down payment signals less financing risk, because you are borrowing less, which can make your offer more attractive when sellers compare several. Price, terms, contingencies, and your timeline matter just as much, and a verified preapproval is what makes an offer serious in the first place.

Does PMI last forever?

On a conventional loan, usually not. Once you build enough equity, typically around 20% of the home's value, you can often request that PMI be removed, and lenders are required to end it automatically once you reach 22% equity based on the original value. FHA loans work differently: their mortgage insurance often stays for the life of the loan on many programs, which is one reason comparing programs matters.

What if I cannot save 20% before I am ready to buy?

That is the situation for most first-time buyers, and it does not have to stop you. Options typically include conventional loans starting at 3% or 5%, FHA at 3.5%, VA or USDA at 0% when you qualify, plus gift funds from family or down payment assistance in some areas. The plan matters more than the percentage, and Kladi will map the realistic paths for the state your property is in.
