How Much Down Payment Do You Actually Need?
The 20% down payment is a myth for most buyers. In reality, the median down payment for first-time buyers in the U.S. is just 8%, according to the National Association of Realtors. Repeat buyers average 19%. Many buyers — especially those using VA or USDA loans — buy with 0% down.
The "right" down payment depends on your loan type, credit score, monthly budget, available savings, and how long you plan to stay in the home. There are compelling arguments for both lower and higher down payments.

Arguments for a Smaller Down Payment
Preserve liquidity — Emergency funds, opportunity investments, and life flexibility matter. Depleting savings for 20% down is risky.
Inflation erodes home debt — If inflation is elevated, your fixed mortgage payment becomes "cheaper" in real terms over time, making leverage favorable.
Appreciation on 100% of value — You benefit from full home price appreciation regardless of your down payment. 5% appreciation on $350K = $17,500 whether you put $10K or $70K down.
Higher return on invested capital — Money not used for a down payment can potentially earn more in the stock market or other investments.
Get into the market sooner — In appreciating markets, waiting to save 20% while home prices rise can cost more than PMI.
Arguments for a Larger Down Payment
Eliminate PMI — 20% down removes $100–$400/month in PMI instantly, with permanent effect.
Lower interest rate — Higher down payment typically earns a slightly better rate through reduced LTV risk pricing.
Lower monthly payment — More manageable budget, lower DTI.
Built-in equity cushion — Protection if market values decline.
Stronger offers in competitive markets — Sellers prefer buyers with larger down payments (lower perceived financing risk).
Down Payment Sources
Savings/checking accounts — Must be seasoned 60+ days in most cases
Gift funds — FHA: 100% of down payment can be gifted. Conventional: varies by program. Requires gift letter.

Sale of other assets — Stocks, vehicles, other property. Must document source.
Frequently Asked Questions
It depends on your financial situation, local market, and what else you'd do with the money. 20% down eliminates PMI ($100–$400/month) and provides a lower rate and payment. However, if your alternative use of the money earns more than your PMI cost + rate differential, investing it can be better. For most first-time buyers without excess savings, using a lower down payment and preserving liquidity is the practical and financially sound choice.
Yes. Most 401(k) plans allow loans up to 50% of your vested balance (maximum $50,000) for home purchases. The loan must be repaid within 5 years or it's treated as a distribution (taxes + penalty). Some plans also allow first-time hardship withdrawals, but these trigger taxes and a 10% penalty. Roth IRA owners can withdraw contributions (not earnings) at any time without penalty, plus up to $10,000 in earnings for a first-time home purchase.
A gift letter is a signed document from the gift donor stating that funds provided for the down payment are a gift and not a loan requiring repayment. Lenders require gift letters when any portion of the down payment comes from family, friends, employers, or nonprofits. The letter must include the donor's name, relationship to borrower, amount, source of funds, and a statement that no repayment is expected.
