The 20% Myth — and What the Numbers Actually Look Like

Ask most people how much you need to put down on a house and they'll say 20%. That figure has real logic behind it — a 20% down payment on a conventional loan eliminates private mortgage insurance and reduces your loan balance — but it is not a legal minimum, and millions of buyers purchase homes every year with considerably less. According to the National Association of Realtors, the median down payment for first-time buyers has consistently been well below 20% in recent years, often in the range of 6% to 8%.

Understanding this gap between conventional wisdom and actual practice is the first step toward building a realistic savings target. It also helps to separate homebuying myths from facts before you start crunching numbers.

Down payment

The upfront cash amount you pay toward the purchase price of a home, expressed as a percentage. The lender finances the remainder through a mortgage loan.

Private mortgage insurance (PMI)

Insurance that protects the lender if you default, typically required on conventional loans when your down payment is less than 20%. It adds to your monthly payment but can usually be canceled once you've built enough equity.

Loan-to-value ratio (LTV)

The percentage of the home's value that you are borrowing. A $200,000 loan on a $250,000 home is an 80% LTV. Lower LTV ratios generally mean lower lender risk and better loan terms.

Down payment assistance (DPA)

Programs offered by government agencies or nonprofits that provide grants or low-interest loans to help eligible buyers cover some or all of their required down payment.

Gift letter

A signed document from someone giving you money for a down payment confirming that the funds are a gift and do not need to be repaid. Lenders require this to verify the source of funds.

Reserves

Funds remaining in your accounts after you close on a home. Lenders often want to see that you'll have money left over to handle mortgage payments and unexpected expenses after the purchase.

Common Loan Types and Their Minimum Down Payments

The minimum down payment you'll need depends almost entirely on the type of mortgage you're using. Here is a plain breakdown of the most common options:

  • Conventional loans: Backed by Fannie Mae or Freddie Mac, these generally require a minimum of 3% down for qualifying first-time buyers, rising to 5% for repeat buyers in most cases. Credit score requirements are stricter than government-backed loans.
  • FHA loans: Insured by the Federal Housing Administration, FHA loans require 3.5% down if your credit score is 580 or above, or 10% if your score falls between 500 and 579. They carry both upfront and annual mortgage insurance premiums. Our overview of FHA loan strengths and limitations covers the full picture.
  • VA loans: Available to eligible veterans, active-duty service members, and surviving spouses, VA loans backed by the U.S. Department of Veterans Affairs typically require no down payment at all.
  • USDA loans: For properties in eligible rural and some suburban areas, USDA loans backed by the U.S. Department of Agriculture can also offer zero down payment options for qualifying borrowers.

Each program has income limits, property eligibility rules, and credit requirements. A HUD-approved housing counselor can help you determine which programs you may qualify for.

The Trade-Offs: Putting Down More vs. Less

There is no universally correct down payment amount — only the one that fits your financial situation and goals. Weighing the genuine trade-offs is essential.

Advantages of a larger down payment

  • Lower monthly mortgage payment due to a smaller loan balance
  • Likely elimination of private mortgage insurance on conventional loans
  • Potentially better interest rate offers from lenders
  • More equity from day one, which provides a buffer if home values dip

Advantages of a smaller down payment

  • Preserves cash for closing costs, emergency reserves, and immediate repairs
  • Allows you to buy sooner rather than spending years saving more
  • Keeps funds available for other financial priorities

Don't Drain Every Account to Hit 20%

Putting 20% down has clear financial advantages, but reaching that number at the expense of your emergency fund can backfire quickly. Most financial professionals suggest keeping three to six months of living expenses liquid after closing. A slightly smaller down payment that leaves you with reserves is often a stronger overall position than a larger one that leaves you cash-strapped from day one.

One caution worth naming plainly: depleting your savings entirely to reach a larger down payment can leave you financially exposed the moment something goes wrong in the home. Lenders generally like to see reserves — funds remaining after closing — as part of your overall financial profile. Review the full scope of upfront costs by consulting our guide to closing costs, which often add 2% to 5% of the purchase price on top of the down payment.

Where Down Payment Money Can Come From

Lenders scrutinize the source of your down payment funds, so it matters where the money originates. Acceptable sources typically include:

  • Personal savings and checking accounts — the most straightforward source
  • Investment and retirement accounts — withdrawals may trigger taxes and penalties; consult a financial professional before tapping retirement funds
  • Gift funds — permitted by most loan programs when accompanied by a signed gift letter from the donor
  • Down payment assistance programs — state housing finance agencies, local governments, and some nonprofits offer grants or deferred-payment second loans to eligible buyers
  • Proceeds from the sale of another home — applicable to move-up buyers

What lenders look for is a documented, verifiable paper trail. Unexplained large deposits shortly before closing can raise compliance red flags and delay your approval. Start organizing your financial groundwork well before you're ready to make an offer.

What Affects the Down Payment You'll Actually Need

Beyond loan type, several variables shape the down payment that makes sense — or that a lender will accept — in your specific transaction:

Credit score
Higher scores unlock lower minimum requirements on some loan programs and better interest rates. A lower score may push your required down payment up.
Property type
Lenders treat multi-unit properties, condos, and investment properties differently than single-family primary residences. Down payment minimums are typically higher for non-primary-residence purchases.
Purchase price relative to appraised value
Your down payment is calculated on the purchase price, but lenders lend against the appraised value. If an appraisal comes in below the agreed price, you may need to cover the gap out of pocket.
Debt-to-income ratio
A high debt load relative to your income may cause lenders to require more down payment to reduce their risk exposure.
Local market conditions
In highly competitive markets, buyers sometimes offer larger down payments to signal financial strength to sellers — though this is a negotiating consideration rather than a lender requirement.

Deciding whether to buy now or continue renting while you save more involves trade-offs that extend well beyond the down payment alone. Our renting vs. buying comparison can help you think through the broader decision with clear eyes.
