The belief that you need 20% down to buy a house is one of the most expensive myths in real estate, because it keeps people renting for years longer than they need to. Someone hears that a $400,000 home requires $80,000 in cash and decides homeownership is hopeless, when the real minimum might be a fraction of that. The 20% figure is a threshold that does one specific thing, nothing more, and most buyers never actually hit it. Here is what you really need to put down by loan type, when a larger down payment is genuinely worth it, and how gifts and assistance programs can close the gap.
Twenty percent down is not a legal requirement and never has been. It comes from one real consequence: on a conventional loan, putting 20% down is the point at which you avoid private mortgage insurance. That is a meaningful benefit, which is why the number stuck in everyone's head. But it got mistranslated over the years into a belief that you cannot buy at all without it. You absolutely can. With 55+ years combined in real estate and lending, we call this the most expensive myth in the business precisely because of how many able buyers it keeps renting. Plenty of buyers put down far less and become homeowners, they simply pay mortgage insurance until they build enough equity, which is often a fine trade.
The actual minimum depends entirely on the loan program, and they range from a little to nothing at all. (Program minimums and rules can change over time, so confirm the current requirements with a lender before you plan around any specific figure.)
So depending on who you are and where you are buying, the floor ranges from nothing to a few percent. A free Roadmap conversation is the fastest way to learn which programs fit you and what your actual numbers look like.
The main thing 20% down buys you is the removal of mortgage insurance on a conventional loan. When you put down less than 20% on a conventional loan, you pay private mortgage insurance, a monthly cost that protects the lender, not you. Reach 20% equity and, on a conventional loan, that cost can come off, which lowers your payment. A larger down payment also means a smaller loan, a lower monthly payment, and less interest paid over time, and it can make your offer look stronger to a seller. Those are real benefits.
But they come at a real cost too: the cash, and the down payment is only one piece of what you bring to closing (how much money you need to buy a house covers the full picture). Draining your savings to reach 20% can leave you with no reserves, which is dangerous, since a home comes with repairs and surprises. The right answer depends on how much cash you have and what else you need it for.
For many buyers, putting down less, keeping a healthy cash cushion, and paying mortgage insurance for a while is the smarter financial decision, even though it sounds counterintuitive.
One important wrinkle: not all mortgage insurance behaves the same. On a conventional loan, the private mortgage insurance can typically be removed once you reach enough equity. On a standard low-down-payment FHA loan, the mortgage insurance generally stays for the life of the loan, and most FHA buyers eliminate it by later refinancing into a conventional loan or by selling. That difference is worth weighing alongside the down payment percentage when you choose between programs.
A lot of buyers do not realize how much of the down payment can come from someone else. Most loan programs allow gift funds from family for some or all of your down payment, provided the money is properly documented. The giver writes a gift letter stating the money is a gift and not a loan, and the funds are traced through bank statements so the underwriter can confirm where they came from. The rules vary by program and by how much you are putting down, so check the specifics, but the headline is that family help is a normal, accepted source of down payment money, and underwriters handle documented gifts every day.
Beyond gifts, there are down payment assistance programs run by state and local housing agencies and other organizations, often aimed at first-time and moderate-income buyers. They come in different forms:
Eligibility usually depends on income limits, the purchase location, and sometimes completing a homebuyer education course. These programs are underused simply because buyers do not know they exist. (Availability, terms, and eligibility for these programs change frequently and vary by area, so check what is currently offered where you are buying.)
The down payment you actually need is almost certainly far less than 20%, and possibly zero depending on the loan you qualify for. The bigger question is how much you should put down given your cash, your reserves, and your goals. Twenty percent removes conventional mortgage insurance and shrinks your loan, but emptying your savings to get there can be a mistake. Look at the real minimums for the programs you qualify for, factor in gift funds and assistance you may be eligible for, and choose a down payment that gets you into the home without leaving you financially exposed. The myth that keeps people renting is the belief that the number has to be huge. It does not.
Stop guessing what you can really afford
Tell Josh and his team your situation, and you'll get the exact price range you qualify for, the loan that gets you the most home for your money, and a step-by-step plan to close. They handle your loan directly, never a referral, and go far beyond a basic pre-approval, so you stop second-guessing, tour with confidence, and write offers sellers take seriously.
Build my Roadmap →No. Twenty percent has never been a requirement; it is simply the point at which a conventional loan stops charging private mortgage insurance. Most buyers put down far less and become homeowners, paying mortgage insurance until they build enough equity, which is often a reasonable trade.
It depends on the program. Conventional loans can go as low as 3% for many first-time buyers and 5% more generally, FHA requires 3.5% with a qualifying credit score, and VA and USDA loans allow 0% down for eligible buyers. These minimums can change, so confirm current requirements with a lender.
Mainly when you can do it without draining your reserves. Twenty percent down removes private mortgage insurance on a conventional loan, shrinks your loan, lowers your payment, and can strengthen your offer. But emptying your savings to reach it is risky, since homes bring repairs and surprises, so a smaller down payment with a healthy cash cushion is often smarter.
Yes. Most loan programs allow gift funds from family for some or all of your down payment, as long as the money is documented with a gift letter stating it is a gift and not a loan, and traced through bank statements. The exact rules vary by program and by how much you are putting down, so confirm the specifics.
Down payment assistance refers to programs from state and local housing agencies and other organizations that help cover your down payment, often for first-time or moderate-income buyers. They take forms like grants, forgivable or deferred loans, and favorable second mortgages, with eligibility usually tied to income, location, and sometimes a homebuyer education course. Availability and terms vary by area and change often.
