Quick answer
A down-payment plan needs more than a percentage of the purchase price. Estimate the down payment for loan scenarios you may qualify for, add closing costs and prepaid items, moving and initial repair money, and preserve an emergency cushion. Divide the remaining gap by the number of months before purchase. Keep near-term home-purchase cash in a place whose principal, access, and insurance fit the closing date rather than relying on a current APY or stock-market return.
Build the full cash-to-close target
cash target = down payment + estimated closing costs + moving/initial costs + reserve
The CFPB says closing costs depend on the home price, down payment, loan, and location, and gives a typical rough range of 2% to 5% of the purchase price excluding the down payment. Use that only as an early estimate; replace it with lender Loan Estimates and the final Closing Disclosure.
| Component | Assumption | Illustrative amount |
|---|---|---|
| Down payment | 5% scenario | $15,000 |
| Closing costs | 3% planning estimate | $9,000 |
| Moving and initial costs | Household estimate | $3,000 |
| Post-closing reserve | Household estimate | $12,000 |
| Total | Before credits or assistance | $39,000 |
These inputs are hypothetical, not a loan quote or recommended percentage.
Compare loan scenarios, not down payment alone
The CFPB notes that many loans require at least 3% down and that many lenders or loan types require 5% or more. HUD says an FHA-insured loan can have a down payment as low as 3.5% for eligible borrowers and properties. Eligibility, credit, property, occupancy, loan limits, mortgage insurance, and lender overlays apply.
For each scenario, compare:
- cash required at closing;
- interest rate and annual percentage rate;
- upfront and monthly mortgage insurance;
- total estimated monthly payment including tax, insurance, and association dues;
- lender credits or points and their tradeoffs; and
- cash remaining after closing.
A larger down payment can reduce borrowing costs but can also leave too little for closing, repairs, or a financial shock. The right comparison uses complete Loan Estimates.
Calculate the monthly savings gap
monthly savings = (cash target - current eligible cash - confirmed assistance) ÷ months
Using the hypothetical $39,000 target, $9,000 already saved, and 24 months:
($39,000 - $9,000) ÷ 24 = $1,250 per month
Do not count a grant, gift, seller credit, or assistance program until eligibility, documentation, limits, and interaction with the loan are confirmed.
Choose an account by the purchase window
A home purchase within a few years can be delayed by an investment loss. An eligible insured savings or money market deposit account prioritizes principal protection and access, subject to coverage and account terms. A CD or Treasury bill fits only when its maturity leaves time before closing and early access is understood. See short-term cash options and HYSA vs. Treasury bills.
Assistance and counseling
State and local programs can offer grants, second loans, forgivable loans, or matched savings, each with income, property, occupancy, education, repayment, and first-time-buyer rules. Use a state housing finance agency, participating lender, or HUD-approved housing counselor. Do not treat a national program count as proof that you qualify.
Before making an offer
- Preserve cash for closing, moving, and repairs.
- Compare Loan Estimates from multiple lenders on aligned assumptions.
- Confirm the source and documentation for every deposit, gift, and assistance amount.
- Avoid new debt or account changes without asking the lender how underwriting could be affected.
- Review the Closing Disclosure and verify cash to close before transferring funds.
Frequently asked questions
Is 20% down required?
No. Eligible loans can allow less, including FHA financing as low as 3.5% and some loans at 3%. A smaller down payment can change mortgage insurance, rate, fees, monthly payment, and qualification.
Should down-payment money be invested in stocks?
If the purchase is near and cannot tolerate a delay, stock-market loss may be incompatible with the goal. Match the account to the date and loss tolerance.
Are seller or lender credits free?
No. The CFPB notes that a seller may seek a higher price and a lender may charge a higher rate or loan amount. Compare total costs.
