A good down payment is one you can afford without emptying your savings or taking on debt you cannot service
The percentage matters less than your actual financial position. A 20% down payment is often called the gold standard because it avoids private mortgage insurance (PMI) and shows lenders you have serious capital. But a 10% down payment on a house you can genuinely afford is better than a 20% down payment that leaves you with three months of expenses in the bank and no room for the furnace to fail.
The real question is not what percentage looks good on paper. It is whether you can make the down payment, cover closing costs, keep an emergency fund intact, and still have monthly cash flow to handle the mortgage payment plus property tax, insurance, and maintenance. A good down payment leaves you standing on solid ground, not balanced on the edge of one unexpected bill.
Key Takeaways
- A good down payment is one that does not drain your emergency fund or force you to borrow money to cover it.
- Putting down 20% avoids PMI but is not required — 10%, 5%, or even 3% down payments exist and may make sense for your situation.
- The monthly payment, not the down payment size, determines whether you can actually afford the house.
- Closing costs typically run 2% to 5% of the purchase price and must come from your own funds, separate from the down payment.
- The lower your down payment, the higher your monthly mortgage payment will be, because you are borrowing more and paying PMI.
How down payment size changes your monthly cost
The down payment directly affects how much you borrow, which directly affects your monthly payment. On a $300,000 house with a 30-year mortgage at 7% interest, the difference is stark.
| Down Payment | Amount Borrowed | Monthly Payment (Principal + Interest) | PMI (if applicable) | Total Monthly Cost |
|---|---|---|---|---|
| 20% ($60,000) | $240,000 | $1,596 | None | $1,596 |
| 10% ($30,000) | $270,000 | $1,797 | ~$135 | ~$1,932 |
| 5% ($15,000) | $285,000 | $1,897 | ~$215 | ~$2,112 |
| 3% ($9,000) | $291,000 | $1,937 | ~$290 | ~$2,227 |
The monthly difference between 20% and 3% down is $631 per month. That is $7,572 per year. If your household income is $80,000, that difference is material. If it is $200,000, it is less so. A good down payment is one where the resulting monthly payment fits inside your actual budget — not a budget you hope to have, but the one you have now.
PMI is the cost you pay when you put down less than 20%. It protects the lender if you default, but you pay for it. PMI typically ranges from 0.5% to 1.5% of the loan amount per year, divided into your monthly payment. You can remove it once you reach 20% equity in the home, but that takes years.
The difference between down payment and closing costs
Many people confuse these two. They are separate money, and both must come from you.
The down payment is your stake in the house — the percentage of the purchase price you pay upfront. The closing costs are fees paid to the lender, title company, appraiser, inspector, and others who process the sale. Closing costs typically run 2% to 5% of the purchase price. On a $300,000 house, that is $6,000 to $15,000.
If you are putting 10% down on a $300,000 house, you need $30,000 for the down payment plus $6,000 to $15,000 for closing costs — a total of $36,000 to $45,000 in cash before you own anything. A good down payment plan accounts for both. If you have saved $40,000 total, putting 10% down leaves you short on closing costs, and you would need to ask the seller to cover some of them or reduce the down payment to 5%.
When a smaller down payment makes sense
A 20% down payment is not a requirement, and it is not always the right choice. If you have stable income, manageable debt, and the monthly payment fits your budget, a 10% or even 5% down payment can be reasonable.
Smaller down payments make sense when: you have a solid emergency fund (three to six months of expenses) that the down payment will not touch; your debt-to-income ratio is low enough that lenders will approve you; you plan to stay in the house long enough for the PMI cost to be worth it; and you have other financial goals (retirement savings, education funding) that matter as much as owning a house sooner.
Smaller down payments do not make sense when: you are scraping together every dollar to reach 10% and have no emergency fund left; you are counting on a bonus or job change to cover the monthly payment; you have high credit card debt or student loans that already strain your budget; or you are buying in a market where prices are rising fast and you feel pressured to move now.
How much emergency fund to keep after the down payment
A good down payment leaves you with money in reserve. Most financial advisors recommend keeping three to six months of living expenses in a savings account you do not touch. That means rent or mortgage, utilities, food, insurance, transportation — the baseline costs of your life.
If your monthly expenses are $4,000, you should have $12,000 to $24,000 in savings before you make a down payment. If you have $50,000 saved and your expenses are $4,000 per month, putting down $30,000 leaves you with $20,000 — enough for five months of expenses. That is solid. Putting down $40,000 leaves you with $10,000 — enough for 2.5 months. That is thin, especially if you are about to take on a mortgage payment that will increase your monthly obligations.
Homeownership brings unexpected costs. A roof leak, a furnace failure, or foundation cracks can cost thousands. If you have no cushion, you end up financing these repairs with credit cards or a home equity line of credit, which defeats the purpose of building equity in the first place.
The role of your credit score and debt
Lenders care about your down payment size, but they care more about whether you can repay the loan. A larger down payment helps, but it does not override a low credit score or high existing debt.
If your credit score is below 620, most conventional lenders will not approve you at all, regardless of down payment. If it is between 620 and 680, you may face higher interest rates and stricter requirements. If it is above 740, you get the best rates and more flexibility on down payment size.
Your debt-to-income ratio (DTI) is the total of all your monthly debt payments divided by your gross monthly income. Most lenders want to see a DTI below 43%, meaning your mortgage payment plus car loans, student loans, credit cards, and other debts should not exceed 43% of what you earn before taxes. A good down payment is one that, combined with your income and existing debt, keeps you under that threshold. If your DTI is already at 40%, a smaller down payment might push you over the limit and disqualify you entirely.
Down payment information and where it comes from
If you cannot save 10% or 20% on your own, down payment information programs exist. These come from state housing finance agencies, nonprofits, and some employers. They typically cover 3% to 5% of the purchase price and may be a grant (you do not repay it) or a second loan (you do).
State housing finance agencies run programs in every state. You can find yours by searching "[your state] housing finance agency." These programs often have income limits and require you to take a homebuyer education course. Nonprofits like NeighborWorks and local community development organizations also offer information, sometimes paired with below-market interest rates.
Some employers offer down payment information as a benefit. If yours does, read the terms carefully — some require you to stay with the company for a set number of years, or you must repay the information if you leave.
A good down payment, with or without information, is still one that does not overextend you. If a program requires you to take on a second loan to cover the down payment, your total monthly debt increases, and you need to account for that in your budget.
Frequently Asked Questions
Is 10% down payment enough to get approved for a mortgage?
Yes, most lenders approve mortgages with 10% down if your credit score is 620 or higher and your debt-to-income ratio is below 43%. You will pay PMI, which increases your monthly payment, but you will own the house. The lender cares more about your ability to repay than the size of your down payment.
Can I use a gift from family for my down payment?
Yes, most lenders allow down payment gifts from family members. You will need a signed gift letter stating the money is a gift, not a loan, and the lender will verify the funds are in your account. The gift cannot come with any expectation of repayment or a claim on the house.
What happens if I put down less than 20% and want to remove PMI later?
You can request PMI removal once you reach 20% equity in the home through a combination of down payment and principal payments. This typically takes five to ten years, depending on your down payment size and how fast you pay down the loan. Some lenders remove it automatically once you hit 22% equity.
Should I delay buying a house to save a larger down payment?
Not necessarily. If you are paying rent that equals or exceeds what a mortgage payment would be, and you have a stable income and emergency fund, buying now with 10% down may build more wealth than waiting two years to save 20%. The trade-off is paying PMI for a few years. Run the numbers for your situation — sometimes waiting makes sense, sometimes it does not.
What if I cannot afford the down payment and closing costs together?
Ask the seller to cover some closing costs as part of the negotiation. In a buyer's market, sellers often pay 2% to 3% of the purchase price in closing costs to make a deal happen. You can also look for down payment information programs in your state, or reduce your down payment to 5% or 3% if you may have access to for a loan that allows it.
