How Much to Put Down on a House: 3% to 20% Scenarios with Real Numbers (2026)
The "save 20% or else" advice ignores the math for most buyers. Here is every down payment option from 0% to 20% with exact PMI costs, monthly payments, total cost comparisons, and the opportunity cost of waiting.
Down Payment Options on a $400,000 Home
Rate: 6.37% (30-year fixed, April 2026 avg). PMI estimated for 700+ credit score. Property tax 1.1%, insurance $1,800/year.

| 0% (VA) | $0 | $400,000* | None | $2,642 | N/A |
| 3% (Conv) | $12,000 | $388,000 | $162/mo | $2,736 | ~7 years |
| 3.5% (FHA) | $14,000 | $393,760** | $177/mo | $2,767 | Never*** |
| 5% (Conv) | $20,000 | $380,000 | $158/mo | $2,669 | ~6 years |
| 10% (Conv) | $40,000 | $360,000 | $120/mo | $2,478 | ~4 years |

*VA loan includes 2.15% funding fee ($8,600) financed into loan. **FHA includes 1.75% upfront MIP financed. ***FHA MIP is permanent with less than 10% down.
Understanding PMI and How to Remove It
Private Mortgage Insurance (PMI) is required on conventional loans when you put less than 20% down. It protects the lender, not you, against default. PMI costs 0.3-1.5% of the loan amount annually, depending on your credit score and loan-to-value (LTV) ratio.
Automatic Termination
PMI drops off when your loan balance reaches 78% of the original purchase price, based on the payment schedule. No action needed.
Borrower Request at 80%
You can request PMI removal at 80% LTV. May require a new appraisal ($400-$600) to confirm the home value supports the 80% threshold.
Lender-Paid PMI
Some lenders offer a slightly higher interest rate (0.125-0.25%) instead of a separate PMI charge. No separate payment, but you pay the higher rate for the life of the loan.
The 20% Down Payment Myth
The math of waiting to save 20%
Home price today: $400,000. You have $20,000 saved (5% down). To reach $80,000 (20%), you need $60,000 more.
Saving $1,500/month, it takes 3.3 years to save $60,000.
During that time, you pay rent: 40 months x $1,800 = $72,000 in rent
At 3.5% annual appreciation, the $400,000 home is now worth $448,500. Your 20% target moved from $80,000 to $89,700.
Meanwhile, buying now with 5% down: $20,000 down + $158/month PMI for ~6 years = $11,376 total PMI cost. Your home has appreciated $48,500 and you have built ~$30,000 in equity through payments.
Waiting for 20% is not always wrong. It makes sense when home prices are declining, when you expect a significant income increase soon, or when the PMI cost is unusually high (low credit score + high LTV). But for most buyers in a stable or appreciating market, buying sooner with less down and paying PMI for a few years costs less than waiting.
Down Payment Assistance Programs
State HFA Programs
Every state has a Housing Finance Agency offering grants, forgivable loans, or low-interest second mortgages for down payment assistance. Income limits typically 80-120% of area median income. Search your state HFA website or visit the NCSHA directory.
FHA Gift Rules
100% of the FHA down payment (3.5%) can come from a gift. Eligible donors include family members, employers, labor unions, and close friends with documented relationships. A gift letter and paper trail of the transfer are required.
IRA First-Time Buyer Withdrawal
First-time buyers can withdraw up to $10,000 from a traditional IRA without the 10% early withdrawal penalty (taxes still apply). Roth IRA contributions (not earnings) can be withdrawn at any time without tax or penalty.
Employer Assistance Programs
Some employers offer down payment assistance as a benefit, particularly in high-cost areas. These range from forgivable loans to matching programs. Ask your HR department.
Closing Costs on Top of Down Payment
Closing costs run 2-5% of the loan amount, paid at closing in addition to your down payment.
| Cost Item | Typical Range |
|---|---|
| Loan origination fee | 0.5-1% of loan ($1,900-$3,800) |
| Appraisal | $400-$700 |
| Title insurance | $1,000-$3,000 |
| Title search and exam | $300-$600 |
| Recording fees | $100-$300 |
| Prepaid property taxes | 2-6 months ($733-$2,200) |
| Prepaid homeowner insurance | 12 months ($1,800) |
| Escrow setup | 2-3 months taxes + insurance |
| Survey | $300-$500 |
Seller concessions can cover some or all closing costs (up to 3-6% of sale price depending on loan type and down payment). Negotiate this in your offer.
