How to Save for a Down Payment on a House

The down payment is the largest single obstacle between renting and owning, and it is also the one most distorted by folklore. The 20% figure everyone repeats is not a requirement, and the money you need is not only the down payment. This guide sets out the real target, what a smaller one actually costs, where to keep the money while it grows, and how to judge the choice almost nobody frames properly — whether to wait at all.

How much you actually need

Twenty percent is a threshold, not a rule. It removes private mortgage insurance on a conventional loan and usually earns the best rate. Below it, several routes exist:

• Conventional loans — as little as 3% down for many buyers, with PMI until you build enough equity.
• FHA loans — 3.5% down with a credit score of 580 or above, but mortgage insurance that lasts the life of the loan unless you put 10% down, in which case it runs 11 years.
• VA loans — 0% down and no monthly mortgage insurance, for eligible service members, veterans and some surviving spouses.
• USDA loans — 0% down in designated rural areas, subject to income caps.

On a $350,000 home those paths are $70,000, $12,250, or nothing at all. The gap between them is measured in years of saving, which is why the choice deserves more thought than a default assumption.

The number is larger than the down payment

Closing costs — lender fees, title, appraisal, prepaid taxes and insurance — typically add 2–5% of the price, due in cash at the same time. On that $350,000 home, another $7,000 to $17,500. Lenders may also want to see cash reserves after closing, often two months of payments, and the house will ask for money immediately in ways no one budgets for: a locksmith, a washing machine, the curtains nobody thinks about until the first night.

Set the target as down payment plus closing costs plus a small buffer, or you will hit your goal and discover you are still several thousand dollars short of being able to close.

What PMI actually costs — and when it stops

Private mortgage insurance protects the lender, not you, which is why it feels like a penalty. It is usually 0.2% to 1.5% of the loan a year, scaled to your credit score and down payment. At 10% down on that $350,000 home, a $315,000 loan at 0.5% costs about $131 a month.

The part that changes the decision: on a conventional loan, PMI is temporary. You can request cancellation once the balance reaches 80% of the original value, and the servicer must remove it automatically at 78%. Paying $131 a month for a few years to buy several years earlier is a defensible trade — and a very different proposition from FHA insurance, which on a low down payment never comes off at all.

Where to keep the money

Money you will spend within a few years does not belong in the stock market. The reasoning is not caution for its own sake: a 20% drawdown is an ordinary event in equities, and if it lands the month before you close, your purchase is gone. There is no time to recover, and the whole point of the fund is that it will be spent on a specific date.

• Buying within two years — a high-yield savings or money market account. Insured, instantly available, and paying a real rate.
• Two to four years out — a CD ladder can add a little yield while keeping part of the money reachable at each rung.
• Never — individual stocks, crypto, or anything you would be unwilling to spend at its worst price this year.

The difference between a good savings rate and a poor one on $40,000 is a few hundred dollars a year. Worth capturing, but not worth taking risk for: the return on this money comes from what you add to it, not what it earns.

Saving longer versus buying sooner

This is the real decision, and it is genuinely two-sided. Waiting to reach 20% means a smaller loan, no PMI, a lower payment and less total interest. It also means paying rent for the whole wait, while prices and rates move independently of your savings plan.

Put numbers on it. Saving $1,000 a month toward $70,000 takes about 70 months — nearly six years. The same $1,000 reaches a 5% down payment of $17,500 in 18 months. The question is not which end state is better; it is whether five extra years of renting costs less than PMI plus a larger loan. Sometimes it does, particularly where rents are low relative to prices. Often it does not.

Two things make the wait clearly worth it: a rate environment expected to fall, and a savings rate high enough that 20% is genuinely close. Two things argue against it: rising local prices that outrun your saving, and a rent so high it prevents you from saving at all.

Assistance you may already qualify for

Every state, and many cities and counties, runs down-payment assistance — grants, forgivable loans, or low-cost second mortgages. These are chronically underused because buyers assume they will not qualify. Two things are worth knowing before you rule yourself out:

• “First-time buyer” usually means not having owned a home in the past three years, not never having owned one.
• Income caps are set against local median income, so they are far higher in expensive areas than most people expect.

Gift money from family is also permitted by most loan programmes, provided it is documented as a gift rather than a loan, with a signed letter and a traceable paper trail. Cash deposited without provenance causes problems in underwriting.

How to reach the number faster

• Automate a fixed transfer on payday into a separate account, so saving is not a monthly decision.
• Send windfalls straight in — tax refunds, bonuses and gifts arrive outside the budget you already live on, and are the least painful dollars you will ever save.
• Attack housing itself. A temporary move to a cheaper rental is worth more than every subscription cancellation combined.
• Do not raise your target as your savings grow. Deciding you now want a more expensive house is the most common reason the finish line is never reached.

Run your own number

Turn a price into a concrete target with the down payment calculator, add the cash you will need on the day with the closing costs calculator, and set a date with the savings goal calculator. Then check the two decisions that follow from it: what the resulting payment means for your budget in the home affordability calculator, and whether waiting is worth it at all in the rent vs buy calculator.
