Where to Keep a House Down Payment
A down payment has two unusual properties as a savings goal: it’s large, and it has a deadline you mostly control but can’t fully predict. The right home appears when it appears. That combination drives one core principle: money you’ll need within a few years belongs somewhere it cannot shrink.
Why not just invest it?
Because sequence matters more than averages. The stock market’s long-run average return doesn’t help if a 25% drawdown lands the year you find the house — and drawdowns of that size have historically happened with some regularity. An emergency fund delayed is an inconvenience; a down payment cut by a quarter can mean losing the home, paying PMI you’d planned to avoid, or buying at a worse rate tier. For short horizons, the upside isn’t worth the variance.
A common guideline from financial educators: under ~3 years to purchase, keep it entirely in insured cash equivalents; 3–5 years, mostly cash with conservative exceptions; only beyond ~5 years does meaningful stock exposure become defensible — and even then, plan to de-risk as the goal approaches.
The good options
High-yield savings account (HYSA). The default answer. FDIC/NCUA-insured, fully liquid for the moment your offer is accepted, earning a real rate. Keep it at a separate bank from daily checking so it stays psychologically untouchable. (HYSA vs. CD compared here.)
CDs or a CD ladder. If your timeline is reasonably firm — “we’re buying in about two years” — locking a rate removes the risk of falling APYs. Use terms that mature before your earliest realistic purchase date, or a ladder for flexibility. Mind early-withdrawal penalties.
U.S. Treasury bills / money market funds. T-bills (via TreasuryDirect or a brokerage) are backed by the federal government, and their interest is exempt from state income tax — a real edge in high-tax states. Government money market funds offer similar yields with daily liquidity, though they’re investments, not FDIC-insured deposits.
Watch the $250,000 line. FDIC insurance covers $250,000 per depositor, per bank, per ownership category. Large down payments for expensive markets can exceed it — split across banks or use joint titling to stay fully covered.
Practical setup
Open the dedicated account, name it (“House — Spring 2028”), automate a monthly transfer, and calculate the required amount with the savings goal calculator. When you get within a few months of shopping, make sure the money is somewhere that liquidates in days, not weeks — earnest money moves fast after an accepted offer.
