Safe high-yield savings and money market accounts for short-term home buyers

For a 1–3 year home down-payment goal, I’d prioritize principal safety and liquidity over squeezing out the absolute highest APY. That generally means an FDIC-insured high-yield savings account (HYSA) or FDIC-insured money-market deposit account (MMDA), not a money-market mutual fund.

My shortlist

*Rates are variable and can change. Marcus's published rate is 3.50% as of Oct. 2, 2026; Ally's savings and MMA are 3.00% as of Sept. 10, 2026. Current market comparisons show the very best HYSAs around 4% or higher, with some promotional/conditional offers higher still.www.marcus.com

My pick for a couple: I'd lean toward Marcus Online Savings if you want the best combination of simplicity, safety and competitive yield. It has no minimum deposit or fees, and Marcus says transfers of $100,000 or less can be processed the same day under its stated conditions.www.marcus.com

If branch access matters, Capital One 360 Performance Savings is particularly attractive. It has no minimum balance or monthly fee and is FDIC-insured.www.capitalone.com

If you want maximum accessibility, Ally Savings/Money Market is a good alternative. Its MMA offers debit-card/check access, while the savings account has useful goal-organizing features.www.marcus.com+1

The really important safety point

For a joint account, FDIC coverage can be up to $500,000—$250,000 per co-owner in the joint-account ownership category—assuming the account is properly structured and you don't have other joint deposits at that same bank consuming the coverage.www.fdic.gov

So if your down-payment fund is, say, $150,000–$300,000, a properly titled joint FDIC-insured account can potentially keep the entire balance insured. If you're above the applicable limit, I'd split the money among separately insured banks rather than leaving an uninsured portion sitting there.

HYSA vs. money-market account

For this particular goal, I wouldn't pay much attention to the label. An FDIC-insured money-market deposit account is just as safe from bank failure as an FDIC-insured savings account; the FDIC explicitly covers both.www.fdic.gov

What you don't want to confuse it with is a money-market mutual fund at a brokerage. That's an investment product, not an FDIC-insured deposit, and it can lose value. For money you absolutely need for a house purchase, I'd avoid taking that risk.

One strategy I'd use

If you're 2–3 years out, I'd do something like:

Down-payment fund → FDIC-insured HYSA/MMDA → automatic monthly contributions → periodically check whether the APY remains competitive.

As you get within ~6–12 months of buying, I'd become even more conservative about liquidity and avoid locking up money that you'll need for closing.

And don't feel compelled to chase a 0.5% higher rate. On $100,000, going from 3.5% to 4.0% is only about $500 more per year before tax. For a house fund, reliable access and full insurance are worth more than that difference.

Bottom line: Marcus at 3.50% is my cleanest all-around choice today; Capital One is compelling if you value branch access; Ally is excellent for flexibility. If you're willing to shop around, I'd look for an FDIC-insured account paying roughly 4%+ with no strings attached, but I wouldn't compromise insurance or liquidity just to get the highest advertised rate.www.marcus.com

If you tell me roughly how much you have saved ($25k, $100k, $250k, etc.) and whether you're aiming for 1, 2, or 3 years, I can compare the best current accounts and estimate the dollar difference in interest.
