How to Save for a House Down Payment

A down payment is the chunk of cash you pay up front when you buy a house. The size of the down payment shapes the loan, the monthly payment, and a few extra costs like mortgage insurance. Saving one is a long project for most households — but it is a project that breaks down well into smaller pieces.

This is a plain-English guide to saving for a house down payment. For more vocabulary, see interest rate and credit score, plus the Learn hub for related topics. Our saving goals calculator can help you map a target to a monthly contribution, and budget can free up the dollars to send.

How big does a down payment need to be?

Less than people think. The "you need 20% down" rule comes from one specific situation — avoiding private mortgage insurance (PMI) on a conventional loan. Many real-world buyers put down much less.

For example, common minimums on different loan types (the Department of Housing and Urban Development at hud.gov and the CFPB at consumerfinance.gov publish current rules):

• FHA loans — as low as 3.5% down, with a credit score floor.
• VA loans — 0% down for eligible service members, veterans, and certain spouses.
• USDA loans — 0% down in eligible rural areas.
• Conventional loans — as low as 3% down for first-time buyers, but with PMI until you reach 20% equity.

These minimums are floors, not goals. Putting more down lowers the monthly payment, the total interest, and (on conventional loans) eliminates PMI sooner.

What PMI actually is

Private mortgage insurance (PMI) is an insurance policy that protects the lender — not you — if you stop paying. You pay the premium, often as part of your monthly mortgage. It typically runs a few hundred dollars a month depending on the loan size and your credit profile.

The CFPB explains the rule in plain language: on a conventional loan, you can usually request PMI removal once your loan balance hits 80% of the original home value, and it must be removed automatically at 78%. FHA loans handle insurance differently and the premium often stays for the life of the loan unless you refinance.

Other up-front costs you also need

The down payment is not the only check you write at closing. Plan for:

• Closing costs — typically 2-5% of the home price for things like loan fees, title work, escrow, and government fees. The CFPB has a closing-cost explainer.
• Cash reserves — many lenders want to see two to six months of mortgage payments in savings after closing.
• Moving costs — movers, deposits, basic furniture, and the first round of repairs.
• Inspection and appraisal — usually a few hundred dollars each, paid before closing.

A useful rule of thumb: if your target down payment is X, plan for X plus 5-10% of the home price in additional cash needed at closing and just after.

Setting a realistic monthly target

Two simple inputs:

1. Total cash needed — down payment plus closing costs plus a buffer.
2. Timeline — when do you realistically want to buy?

Total divided by months equals your monthly savings target. Our saving goals calculator does this with interest assumptions baked in.

For example, $40,000 in 4 years is roughly $830 a month if the savings earn nothing, or about $750 a month at 4% APY in a high-yield savings account.

Where to keep down-payment savings

Money you plan to spend in the next 1-5 years usually does not belong in the stock market — too much risk that the value drops right when you need it. The Securities and Exchange Commission's investor.gov and the FDIC at fdic.gov both endorse keeping short-horizon savings in low-risk, FDIC-insured (or NCUA-insured at credit unions) accounts:

• High-yield savings account. Easy access, FDIC insured up to limits, often pays much more than a standard checking account.
• Money market account. Similar to savings, sometimes with check-writing.
• Certificates of deposit (CDs). Lock in a rate for a set period. Useful for "I will not touch this for 18 months."
• Series I savings bonds. Treasury bonds with an inflation-linked rate, sold at treasurydirect.gov. One-year minimum lock-up.
• Treasury bills. Short-term federal IOUs, also at TreasuryDirect.

Avoid putting down-payment savings into stocks or stock funds unless your timeline is much longer than 5 years.

Down payment assistance programs

Most states and many cities offer down payment assistance (DPA) programs — grants, forgivable loans, or low-interest second mortgages for eligible buyers. HUD at hud.gov maintains a state-by-state list. Common features:

• Income limits.
• First-time buyer requirements (often defined as not having owned in the past three years).
• A required homebuyer education course.
• Rules about the type of property and price.

A HUD-certified housing counselor at hud.gov can help you find programs you qualify for. The service is free.

Common pitfalls

A few traps to avoid:

• Underestimating closing costs and reserves. A "20% down payment" without buffer money is risky.
• Tapping retirement accounts. Some plans allow it, but the long-term cost is high. The IRS at irs.gov lists the rules and exceptions.
• Stretching the monthly payment. Just because you can be approved does not mean the payment will fit your real life. The CFPB's affordability tool is honest about this.
• Skipping the inspection to win a bid. Costly to fix later.
• Buying with a partner without a written agreement. Property and money disputes get ugly fast — talk first, on paper.

A note on advice

This is general information, not advice. The right size of a down payment depends on your loan type, your credit, your local market, and how long you plan to stay. A HUD-certified housing counselor (free at hud.gov) or a fee-only fiduciary can walk through the specifics.
