YOUR MORTGAGE, EXPLAINED
How Much Down Payment Do You Need to Buy a House?
Compare down payment options by what they do to your monthly payment, loan costs and cash left afterward. The largest down payment is not automatically the best fit. A smaller down payment may preserve flexibility but can increase borrowing costs or mortgage insurance. Available options depend on the loan and your situation.

What to remember
- Compare cash and payment together.
- Mortgage insurance can affect the tradeoff.
- Keep an accessible reserve.
Begin with the money you want to keep
Before assigning every dollar to the purchase, choose a reserve target for your household. Set aside known expenses around the move and money for other goals. Then compare what is actually available for the down payment and transaction costs.

Compare down payment amounts and mortgage insurance
Ask for two or three down payment amounts using the same property, term and pricing date. For each one, compare the total payment, cash to close, cash remaining and any mortgage insurance. This makes the tradeoff visible without declaring one percentage right for everyone.
A hypothetical cash tradeoff
If you have $70,000 and use $45,000 for the purchase and costs, you keep $25,000. If another option uses $60,000, you keep $10,000. The second option may reduce the payment, but it also leaves $15,000 less available. Ask how much monthly relief that extra cash actually buys.
Do you need 20 percent down to buy a house?
A 20 percent down payment is not required for every mortgage. Some eligible conventional borrowers can put down as little as 3 percent, while other loan programs have different requirements. A lower down payment is not automatically the cheapest choice: compare mortgage insurance, rates, fees and the cash you keep. Ask which options you actually qualify for before planning around a minimum.

When waiting may be the better move
If the purchase would use nearly all your accessible cash or depend on new credit card debt afterward, consider a lower price, more time to save or a different plan. Preserving room for real life can be more valuable than reaching a particular down payment number.
