What Most Homebuyers Get Wrong About Mortgage Down Payment Requirements

Fact-checked by the MyFinancial101 editorial team

You’ve been told since your first paycheck that you need 20% down to buy a house. That number burrowed into your brain, it still shows up in family advice, old Google results, and passing comments from coworkers who last bought when rates were 3%. And it’s wrong. Or at least, it’s wildly outdated.

Real mortgage down payment requirements are far lower than most people think. According to the National Association of REALTORS’ 2025 survey, the median down payment for first‑time buyers was just 10% of the purchase price, half the mythical figure. And for a growing slice of buyers, that number dips to 3% or even zero.

This guide cuts through the noise. You’ll see exactly what lenders actually require, what real buyers are putting down, and where the hidden costs and smart shortcuts live. By the end, you’ll know whether to buy now with a small down payment or keep saving, and you’ll have a clear map for avoiding the mistakes that trip up most people.

Step 1: Do I really need a 20% down payment to buy a home?

No. The 20% down payment is a stubborn myth that keeps a lot of earners on the sidelines longer than necessary. Lenders, and the big government‑backed investors they sell to, routinely approve loans with far less money down. In 2025, the median first‑time buyer brought just 10% to the closing table.

Why the myth won’t die

Family, friends, and even some real estate agents still repeat the 20% number. It sticks because it’s simple, and because putting down 20% lets you skip private mortgage insurance, a monthly premium that lenders require on low‑down‑payment loans. But skipping PMI by saving up $80,000 on a $400,000 home may cost you more in rent and missed appreciation than the insurance premium would have cost in the first place.

The Consumer Financial Protection Bureau puts it plainly: “If you cannot make a down payment of 20 percent, lenders usually will require you to purchase private mortgage insurance or obtain an FHA, VA, or USDA loan.” Notice the key word: usually, not “always,” and not “you can’t get a loan.”

What to watch out for

Anchoring on 20% makes you overestimate how much cash you need and can push you to delay homeownership years longer than the math justifies. Meanwhile, home prices have kept climbing, and the money you could have put toward principal and equity disappears into rent.

Step 2: What are the actual minimum down payment requirements for conventional, FHA, VA, and USDA loans?

The straight answer: for conventional loans, you can put as little as 3% down; FHA demands 3.5%; VA and USDA loans allow 0% down for those who qualify. But those numbers only tell part of the story, your credit score and the lender you choose can shift the floor.

How conventional 3%-down loans work

Fannie Mae’s HomeReady and Freddie Mac’s Home Possible programs both accept 3% down payments. Borrowers generally need a credit score of at least 620, though some lenders impose higher overlays. According to Fannie Mae, “most mortgage loan options require a down payment of at least 3% of the home price, but some loan types and lenders can even require 5% down or more.” Freddie Mac notes that its Home Possible mortgages feature flexible sources of funding, which can help buyers bring in gift funds or secondary financing to cover the down payment.

FHA, VA, and USDA specifics

FHA loans, insured by the Federal Housing Administration, require just 3.5% down for borrowers with credit scores of 580 or above. If your score is between 500 and 579, you’ll need 10% down, though many lenders won’t go that low. The CFPB’s resources on FHA loans outline these minimums clearly.

VA loans carry no down payment requirement at all for eligible service members, veterans, and surviving spouses. USDA loans, aimed at rural and some suburban areas, also require $0 down. Both programs have geographic and income limits, and the USDA program charges an upfront guarantee fee that can be rolled into the loan.

No matter which loan you pick, your down payment directly influences your debt‑to‑income ratio. A smaller loan amount means a lower monthly payment, which lowers your DTI and can push you over the approval line if your income is tight. This DTI interaction is something most mortgage guides skip, but it’s one of the fastest ways a few thousand extra dollars in down payment money can turn a “maybe” into a “yes.”

Step 3: How much are first‑time buyers actually putting down in 2025?

According to the National Association of REALTORS’ annual survey, the median down payment for first‑time buyers who purchased between July 2024 and June 2025 was 10% of the purchase price. Repeat buyers put down a median of 23%, largely because they roll equity from a previous sale into the new purchase.

Why not the absolute minimum?

Even though 3% and 3.5% options exist widely, most first‑timers choose to put down more. In competitive markets, offers with larger down payments signal a stronger buyer to sellers, and they reduce the chance that an appraisal gap will kill the deal. Some buyers also want to keep their monthly payment lower or avoid PMI from day one. Still, 29% of first‑time buyers used an FHA loan, proof that low‑down‑payment financing isn’t a fringe choice.

How DTI ties into your down payment choice

Many buyers focus on the down payment dollar amount while ignoring what it does to their debt‑to‑income ratio. Because your DTI compares monthly debt obligations, including the new mortgage payment, to your gross monthly income, a larger down payment shrinks the loan balance and the monthly payment. If your DTI is hovering near the 43% to 45% maximum that many lenders enforce, even a modest bump in down payment can bring your application comfortably under the threshold.

Step 4: How much more does a low down payment cost me over 5–7 years?

It can add up, but the numbers are often smaller than people fear. On a $400,000 home, putting 3% down instead of 10% means you borrow $28,000 more. At a 6.5% interest rate, that extra principal pushes your monthly payment up by roughly $170. Then add PMI: typically 0.5% to 1% of the loan amount per year, or about $150 to $300 a month on the larger loan balance.

Over seven years, that’s around $25,000 in additional cost, but you also bought the home seven years earlier. If the home appreciates just 3% a year, your equity could outweigh the extra expense. And once your equity hits 20%, either through payments or price growth, PMI drops off. If you want to accelerate the equity side, renegotiating high credit card rates can free up cash that you can throw at the principal each month.

Step 5: What down payment assistance programs can I get without repaying them?

Yes, hundreds of state, county, and employer‑sponsored programs offer grants or forgivable loans that cover all or part of your down payment, and many never have to be repaid. The key is understanding the rules: most are reserved for first‑time buyers, primary residences, and income‑qualified households.

State‑level programs that actually cut checks

California’s CalHFA offers a MyHome Assistance Program that provides a deferred‑payment junior loan of up to 3.5% of the purchase price to cover the down payment or closing costs. For example, on a $400,000 home, that’s up to $14,000 in assistance. In Texas, the My First Texas Home program gives qualified buyers up to 5% of the loan amount as a down payment grant. New York’s State of New York Mortgage Agency runs similar initiatives.

These aren’t rare, boutique options. The NAR’s economists have noted that down payment assistance programs are widely available but consistently underutilized because buyers don’t know they exist. Most programs require a homebuyer education course, and reputable credit counseling services can help you locate and apply for the right ones in your area.

What to watch out for

Some DPA programs require you to stay in the home for three to five years, or else the assistance turns into a repayable loan. And if you combine a grant with an FHA loan, the life‑of‑loan mortgage insurance premium may stick with you longer than PMI would on a conventional loan. Read the fine print on recapture and MIP before committing.

Step 6: When should I wait and save for a larger down payment vs. buying now?

If you have steady income, good credit, and a manageable debt load, buying now with a low down payment often wins over waiting, because home prices and rents rarely pause. But in a few specific situations, pressing pause and piling up more cash is the sharper financial move.

Scenarios where a bigger down payment pays off

If your debt‑to‑income ratio is already stretched, adding even a few thousand dollars to the down payment can lower your monthly mortgage enough to bring the DTI below lender cutoffs. Self‑employed borrowers often face additional scrutiny: lenders may require two years of tax returns with strong income and may want to see larger reserves. In those cases, putting 10% or 15% down, instead of the bare minimum, can offset the perception of risk and help you get approved without pricing exceptions.

A larger down payment also solves the appraisal gap problem. If you offer $400,000 but the appraisal comes in at $380,000, the lender will only finance a percentage of the $380,000. A bigger down payment gives you the cash cushion to cover the difference without collapsing the deal. And if you’re sitting on high‑interest student loans, the FHA’s 3.5% down option can actually free up cash you’d otherwise tie up in a large down payment, letting you tackle the loans later while locking in homeownership now.

If you’re still weighing whether to save more or jump in, start by managing high‑interest credit card debt first. Lowering your monthly obligations improves your DTI faster than most people expect, and it gives you more room to handle what a low‑down‑payment loan actually costs.

Frequently Asked Questions

Can I buy a house with 5% down if I have a 640 credit score?

Yes, many conventional lenders will approve a 5%-down loan with a 640 score, though PMI will be higher than it would be at 700. FHA’s 3.5% option is also available, but the FHA’s upfront and annual mortgage insurance may make the conventional route cheaper if you plan to cancel PMI later. Shop both paths and compare the all‑in monthly cost before choosing.

What’s the minimum down payment for a second home?

Second‑home loans typically require at least 10% down, but many lenders ask for 15% or even 20% because the risk is higher. Investment properties, those you plan to rent full‑time, almost always demand a minimum of 15% to 25% down, depending on the loan type and your credit profile.

How do I prove my down payment funds if I’m self‑employed?

Self‑employed buyers need to show two years of tax returns and recent bank statements that trace the source of the down payment money. Large cash deposits that can’t be tied to documented business income raise red flags. If you’re self‑employed and your income fluctuates, a larger down payment, 10% or more, can strengthen the loan file and help offset lender concerns about income stability.

How does my down payment affect my debt‑to‑income ratio?

Your DTI ratio measures your total monthly debts against your gross monthly income. A larger down payment reduces the loan amount, which lowers your principal‑and‑interest payment and, by extension, lowers your DTI. Even a few thousand extra dollars can make the difference between a DTI that’s comfortably under the 43% cap and one that triggers a denial.

Can I use a gift for my down payment?

Yes, most loan programs allow gift funds from family members. Conventional, FHA, VA, and USDA loans all accept gifts, but you’ll need a signed gift letter confirming that the money isn’t a loan. Some DPA programs even allow grants to serve as the entire down payment, effectively turning a gift into a zero‑cash‑out‑of‑pocket purchase.

How does PMI cancellation work if I put 5% down?

On a conventional loan, you can request PMI cancellation once your loan balance reaches 80% of the original home value, assuming you’ve made on‑time payments. It cancels automatically when the balance hits 78%. With FHA loans originated after 2013, mortgage insurance usually stays for the life of the loan unless you refinance into a conventional mortgage.

Is it possible to buy with $0 down in 2025?

Yes, if you qualify for a VA or USDA loan. VA loans require no down payment and no PMI; USDA loans also require no down payment but do charge an upfront guarantee fee and an annual fee. Some state housing finance agencies layer grants on top that can cover the down payment entirely, effectively creating a zero‑down path for buyers who don’t qualify for VA or USDA.

Will a larger down payment help me avoid an appraisal gap?

Absolutely. If your offer is $400,000 and the home appraises for $380,000, the lender will base the loan amount on the lower value. A larger down payment gives you the extra cash to cover that $20,000 gap and still close the deal without renegotiating the sale price. In hot markets where bidding wars push prices above appraised values, this is one of the most practical reasons to bring more cash.

What’s the tax impact of a bigger down payment on mortgage interest deduction?

A larger down payment means a smaller mortgage, which means less mortgage interest to deduct at tax time. But since the standard deduction for a married couple in 2025 is $29,200, most first‑time buyers don’t itemize anyway. For the vast majority, the tax angle is a minor footnote, don’t let it drive your down payment decision.
