Ask most people how much they need to buy a home and you will hear the same number: twenty percent. It is the figure passed down from parents, repeated by friends, and quietly assumed by nearly every first-time buyer sketching out a savings plan. It is also, for a conventional loan, simply not true. The belief that you must have 20% of the purchase price in cash before a lender will talk to you keeps countless qualified renters on the sidelines for years, saving toward a number they do not actually need to reach.
So what are the real conventional loan down payment requirements, and how much should you actually put down? The short answer is that a conventional loan can start at 3% down for eligible buyers, with 5%, 10%, and 20% all being common choices rather than fixed rules. But putting less down is a tradeoff, not a free lunch, and the right number depends on your cash, your comfort with a monthly payment, and how soon you want to own. This post breaks down where the 20% myth came from, the true minimums, what a smaller down payment costs, and a simple way to choose your number.
Where Did the 20% Down Payment Rule Come From?
The 20% figure is real, but it has been badly misunderstood. It is not the amount you need to qualify for a conventional loan. It is the amount at which a lender no longer asks you to carry private mortgage insurance. When you put down less than 20%, your loan is more than 80% of the home’s value, and lenders offset that added risk by requiring an insurance policy that protects them if you default. Reach 20% down, and that requirement disappears. Somewhere along the way, “the point where you avoid an extra fee” hardened in the public imagination into “the price of admission,” and a helpful benchmark became a false barrier.
Understanding that distinction changes everything about how you plan. If 20% is really about sidestepping an insurance premium rather than earning the right to a mortgage, then the decision to put down less is not about whether you are allowed to buy, but about whether the cost of that insurance is worth getting into a home sooner. It helps to understand what private mortgage insurance is and why 20% became the informal benchmark before you decide how much to bring to the table, because that single fee sits at the center of the whole down payment question.
The 20% number is about avoiding PMI, not qualifying
Once you see 20% as a PMI threshold rather than a qualification bar, the fog lifts. A buyer with 6% saved is not disqualified; they are simply a buyer who will carry PMI for a while. A buyer with 20% saved has bought their way out of that premium up front. Both are conventional borrowers in good standing. The question is never “do I have enough to be allowed in,” because for a conventional loan the entry point is far lower than most people think. The question is “how much do I want to put down, and what does each choice cost me?”
How Little Can You Put Down on a Conventional Loan?
For a conventional loan, the practical floor is 3% down for buyers who qualify for one of the low-down programs, and 5% down for most everyone else. From there, the tiers step up in a familiar pattern: 10%, 15%, and 20%, each one shrinking your loan, your payment, and eventually your PMI. There is nothing magical about any single rung. A 3% down payment on a $300,000 home is $9,000; a 5% down payment is $15,000; a 10% down payment is $30,000. Each is a legitimate way to buy the same house, and each comes with a different monthly payment and PMI cost attached.
Because the conventional tiers are only part of the story, it is worth seeing them against the backdrop of every path to homeownership. Government-backed loans have their own rules, and reviewing the wider menu of down payment options across loan types makes it clear that “how much down” is a spectrum, not a single required figure. A buyer who does not fit a 3% conventional program might find an FHA loan at 3.5% down, or a zero-down government-backed option, is a better fit. The point is that the conventional minimum is low, and it is one choice among several.
The 3%-down conventional programs
The 3% conventional floor is not a loophole; it runs through established programs. Conventional 97 allows a 97% loan, meaning 3% down, for a wide range of buyers. HomeReady and Home Possible are 3%-down programs built for first-time buyers or those within certain income limits, and they can come with reduced PMI and more flexible qualifying. These are mainstream conventional options, not fringe products. The catch is that each has its own eligibility rules, such as whether you are a first-time buyer, whether your income falls under a local limit, and whether you will complete a homebuyer education course. That is exactly the kind of detail worth confirming with a loan officer, because qualifying for a 3%-down program can change your whole savings timeline.
What Does a Smaller Down Payment Actually Cost You?
Putting less down gets you into a home sooner, but it is not free, and being clear-eyed about the cost is how you make a good decision. Three things move when your down payment shrinks. First, your loan is larger, so you borrow more and pay more interest over time. Second, your monthly payment is higher, both because the loan is bigger and because you are now carrying private mortgage insurance. Third, a smaller down payment can nudge your interest rate slightly, since lenders price loans partly on how much equity you start with. None of these is a reason to avoid buying; they are simply the price of getting in with less cash.
The good news is that the biggest of those costs, PMI, is temporary on a conventional loan. It is not a permanent tax on buying sooner; it is a bridge you cross while you build equity. For many buyers the real question becomes a matter of timing rather than permanence, which is the deeper decision of whether to buy now with PMI or keep saving toward twenty percent. If home prices or rents are climbing faster than you can save, buying sooner with PMI can cost less in the long run than waiting years to hit 20%. If you are close to 20% already, waiting a few months might make more sense.
PMI is not permanent on a conventional loan
This is the part that makes a low down payment far less scary than it sounds. On a conventional loan, once you build your equity to 20% of the home’s value, you can request that PMI be cancelled, and under federal rules it must automatically drop off once you reach 22% equity based on the original schedule. Your equity grows two ways: through the principal you pay down each month and through any rise in the home’s value. That means the PMI you accept to buy with 5% down is a cost with a built-in expiration date, not a lifelong obligation. For many buyers, a few years of PMI is a reasonable trade for years of earlier homeownership.
So How Much Should You Put Down on a Conventional Loan?
With the myth cleared away, the question turns from “how much am I required to have” to “how much do I want to put down.” A good answer balances four things: the cash you can part with without emptying your savings, the reserves a lender wants to see after closing, the closing costs you also have to cover, and the monthly payment you are comfortable living with. Putting down every last dollar to reach 20% and avoid PMI can backfire if it leaves you with no cushion for a repair or a rough month. Often the smarter move is a middle tier that keeps some cash in reserve.
The clearest way to decide is to work backward from the payment rather than forward from a savings goal. Once you know how large a monthly payment your income can comfortably carry, you can test different down payment amounts against it and see which one lands you in a payment that fits. A larger down payment lowers the payment and can remove PMI; a smaller one preserves cash but raises the payment. Seeing the two side by side, in real dollars for your actual price range, turns an anxious guess into a straightforward choice.
A simple way to land on your number
Start with the total cash you have, then subtract what you need for closing costs and a healthy emergency reserve. What is left is what you can realistically put down. Check that amount against the conventional tiers: does it clear the 3% or 5% minimum, and does it get you close to a payment you like? If reaching 20% would wipe out your reserves, aim lower and plan to cancel PMI later. If you have plenty of cushion and dislike carrying PMI, a larger down payment may be worth it. There is rarely one right answer, only the one that fits your cash, your comfort, and your timeline.
Frequently Asked Questions
How much down payment do you need for a conventional loan?
A conventional loan can be had for as little as 3% down for eligible buyers, and 5% down is common. You do not need 20%. The 20% figure is the point at which you avoid private mortgage insurance, not a requirement to qualify. The right amount for you depends on your cash, your reserves, and how the monthly payment fits your budget, which a loan officer can map out on a Loan Estimate.
Do you have to put 20% down on a conventional loan?
No. This is the most common down payment myth. Twenty percent lets you skip private mortgage insurance and lowers your loan, but conventional financing is available with far less down. Many buyers put down 3% to 10% and simply carry PMI until they build enough equity to cancel it. Waiting years to reach 20% is a choice, not a rule, and it is not always the smarter one.
What is the lowest down payment on a conventional loan?
For eligible buyers, the floor on a conventional loan is 3%, offered through programs such as Conventional 97, HomeReady, and Home Possible. These are aimed largely at first-time buyers or buyers within certain income limits. If you do not fit those programs, 5% down is the typical conventional minimum. Your loan officer can tell you quickly which low-down option you qualify for.
Is it better to put down 20% or less on a house?
It depends on your priorities. Putting 20% down avoids PMI, shrinks your loan, and lowers your payment, but it ties up a large amount of cash and can mean waiting years to buy. Putting less down gets you into a home sooner and keeps cash in reserve, at the cost of PMI and a higher payment until you build equity. Neither is universally right; it is a genuine tradeoff worth running the numbers on.
Do all conventional loans require PMI?
No. Conventional loans require private mortgage insurance only when your down payment is under 20%, meaning your loan is more than 80% of the home’s value. Put down 20% or more and there is no PMI at all. And when you do carry PMI on a conventional loan, it is not permanent: you can request cancellation once you reach 20% equity, and it automatically ends at 22% equity under federal rules.
How is a conventional down payment different from an FHA down payment?
An FHA loan has a minimum down payment of 3.5% and charges mortgage insurance that, on most FHA loans today, stays for the life of the loan unless you refinance. A conventional loan can start at 3% down, and its PMI can be cancelled once you reach 20% equity. FHA is often more forgiving on credit, while conventional can be cheaper over time for stronger-credit buyers. The best fit depends on your full picture.
How much should a first-time buyer put down?
There is no single right number. Many first-time buyers use a 3% or 5% conventional program, or an FHA loan, to buy sooner while keeping savings for closing costs and emergencies. Others put down more to lower the payment. The goal is to land on an amount that gets you into a home you can comfortably afford without draining your reserves, which is exactly the math a loan officer can help you work through.
What Is Your Next Step With Fellowship Home Loans?
The 20% down payment rule is one of the most expensive myths in home buying, because it convinces ready buyers to wait when they could already own. The truth is simpler and far more encouraging: a conventional loan can start at 3% down, the tiers above it are choices rather than hurdles, and the PMI that comes with a smaller down payment is a temporary cost with a clear exit. Knowing that, the real work is not saving to an arbitrary number; it is choosing the down payment that fits your cash, your reserves, and the payment you want to live with.
You do not have to sort the tiers, programs, and PMI math on your own. As a Christian-based, national lender offering conventional and government-backed programs, Fellowship Home Loans will lay out your real options honestly, run the down-payment-versus-PMI numbers on a clear Loan Estimate, and walk you through the full mortgage process from application to closing. The goal is not to push you toward the biggest loan or the largest down payment, but to help you buy a home you can comfortably afford, on terms that make sense for your life.
