The 20 percent down payment is one of the most persistent myths in homebuying. A lot of capable, financially responsible people delay buying for years because they believe they need a fifth of the price in cash before anyone will talk to them. For a conventional loan, that is not how it works, and the gap between what people assume and what the programs actually allow is wide.
A conventional loan, meaning a mortgage not backed by a government program like VA or FHA, offers more down payment flexibility than its reputation suggests. You can put down as little as 3 percent, or as much as 20 percent or more, and each choice changes your monthly payment and your costs in ways worth understanding before you decide. This walks through the real options, what each one costs, and how to think about the right number for your situation rather than a figure someone told you was mandatory.
The range: from 3 percent to 20 percent and beyond
Conventional loans accept down payments across a broad range, and the low end is lower than most people expect.
At the entry point, several conventional programs allow a down payment of just 3 percent of the purchase price. These are real conventional loans, not a separate category, and they are aimed at buyers with solid credit who have not yet saved a large lump sum. They typically expect a credit score around 620 or higher and, for first-time buyers, often a short homeownership education course.
From there, you can put down 5, 10, or 15 percent, which many buyers do to lower their monthly payment or their insurance cost. At 20 percent, you cross an important line that changes the math, which is covered below. And nothing stops you from putting down more than 20 percent if you have it and prefer a smaller loan.
The point is that the down payment is a dial, not a single required setting. Where you set it depends on your savings, your monthly budget, and how long you plan to stay in the home.
What changes at 20 percent: private mortgage insurance
The reason 20 percent gets so much attention is private mortgage insurance, usually called PMI. According to the Consumer Financial Protection Bureau, PMI is a type of insurance you may be required to buy when you take out a conventional loan with a down payment of less than 20 percent of the purchase price. It protects the lender, not you, and it is added to your monthly payment.
Here is the part that is often left out of the conversation, and it matters. PMI on a conventional loan is not permanent. Once you build enough equity, it goes away. The CFPB explains that PMI generally cancels automatically once your loan balance reaches 78 percent of the home's original value, and you can usually request cancellation earlier, at 80 percent. So a smaller down payment with PMI is not a life sentence. It is a temporary cost that ends as you pay the loan down.
That reframes the 20 percent question entirely. The choice is not "pay 20 percent or pay PMI forever." It is whether to wait and save a larger down payment, or to buy sooner with a smaller one and carry PMI for a while until your equity removes it. Neither answer is automatically right. They are different trade-offs, and the better one depends on your timeline and what your money could do in the meantime.
What a smaller or larger down payment actually costs
The size of your down payment moves three things at once: your monthly payment, your insurance cost, and your loan-to-value ratio, which is the share of the home's value you are borrowing. A larger down payment means a smaller loan, a lower monthly payment, and a lower loan-to-value ratio, which can also improve the terms a lender offers.
A smaller down payment does the opposite. You borrow more, your monthly payment is higher, and you carry PMI until your equity reaches the cancellation point. But it also lets you keep more cash on hand for moving costs, repairs, and the ordinary surprises of owning a home, and it lets you buy sooner rather than spending another year or two saving.
The CFPB has a plain-English explanation of how the down payment amount affects your loan terms that is worth reading before you settle on a number. The honest takeaway is that there is no universally correct down payment. There is only the one that fits your budget and your plans, and figuring that out is exactly the kind of math a good loan officer should run with you.
Where the down payment can come from
Another common worry is that every dollar of the down payment has to come from your own savings. For conventional loans, that is often not the case.
Gift funds are widely allowed. The CFPB notes that in most cases you can use gift money from a family member or, in some situations, a friend toward your down payment. Lenders will ask for documentation, usually a gift letter confirming the money is a gift and not a loan, along with a record of the transfer. Some low-down-payment conventional programs are flexible enough that a large share of the down payment and closing costs can come from gifts or assistance.
Down payment assistance programs are another source. These vary widely by state and locality, and the rules around them can be detailed, so the right move is to ask a loan officer what is available and what conditions apply. The takeaway is that your own savings account is not the only place a down payment can come from, and ruling yourself out because you have not saved the full amount is often a mistake.
How to think about the right number for you
Start with what you can comfortably carry each month, not with a down payment target. Your monthly payment includes principal, interest, property taxes, homeowners insurance, and PMI if your down payment is under 20 percent. A loan officer can show you how that total payment shifts as you move the down payment up or down, so you can see the real trade-off instead of guessing.
Then weigh three things together: how much cash you can put in without draining your safety net, how the monthly payment fits your budget at each down payment level, and how long you expect to stay in the home. A buyer planning to stay many years may value a lower payment and choose to put more down. A buyer who wants to buy now and keep cash in reserve may choose a smaller down payment and let PMI fall off later. Both can be sound decisions.
This is the full-picture view, and it beats chasing a single number. The lowest down payment is not automatically the smartest, and neither is the largest. The smartest is the one that lets you buy a home you can hold onto comfortably through the ordinary ups and downs of life.
A short conversation makes this concrete. GoodLoan (NMLS #) works with conventional loans across this entire down payment range and can model several scenarios with your actual numbers, including how soon PMI would come off at each level. We also say no when a purchase would stretch you too thin, because the goal is a loan you can comfortably live with rather than simply one you can qualify for. The first step is a call, not an application.
Frequently asked questions
What is the minimum down payment on a conventional loan?
Several conventional programs allow as little as 3 percent down for qualified buyers, typically with a credit score around 620 or higher. First-time buyers may also need to complete a homeownership education course. You are not required to put down 20 percent.
Do I have to pay PMI if I put down less than 20 percent?
Usually yes. The CFPB explains that PMI is generally required on a conventional loan when your down payment is under 20 percent. The important point is that it is temporary. PMI typically cancels automatically once your loan reaches 78 percent of the home's original value, and you can often request removal at 80 percent.
Is it better to put down 20 percent or buy sooner with less?
It depends on your timeline and finances. A larger down payment lowers your monthly payment and avoids PMI, while a smaller one lets you buy sooner and keep more cash in reserve. PMI ends as you build equity, so a smaller down payment is not a permanent cost. A loan officer can show you both paths with your own numbers.
Can I use gift money for my down payment?
In most cases, yes, on a conventional loan. Lenders generally accept gift funds from a family member, and sometimes a friend, with documentation such as a gift letter and proof of the transfer. Ask your loan officer what documentation your specific loan will require.
How does my down payment affect my monthly payment?
A larger down payment means you borrow less, which lowers both your monthly payment and your loan-to-value ratio, and it can remove PMI. A smaller down payment raises your monthly payment and adds PMI until your equity reaches the cancellation point. The down payment is essentially a dial that adjusts your monthly cost.
What if I have good income but limited savings?
You may still have strong options. Low-down-payment conventional programs, gift funds, and down payment assistance can each close part of the gap. The best first step is to talk with a loan officer who can look at your full situation and tell you honestly what you can do today.
