The down payment on an $800,000 house typically ranges from $16,000 to $400,000, depending on the loan type and your lender's requirements

The amount you put down is not fixed by law — it depends on which mortgage program you use. A conventional loan (the most common type) usually requires between 3% and 20% down. On an $800,000 house, that means $24,000 to $160,000. Federal Housing Administration (FHA) loans allow as little as 3.5% down, which would be $28,000. Veterans Affairs (VA) loans and United States Department of Agriculture (USDA) loans may require no down payment at all, though you must meet specific may be able to access requirements for each.

Your actual down payment also depends on what your lender will accept. Some lenders have minimum down payment requirements higher than the program allows. A lender might require 10% down even though the loan type permits 5%. Before you settle on a number, you need to talk to actual lenders, not just calculate percentages.

Key Takeaways

  • Conventional loans on an $800,000 house typically require 3% to 20% down, or $24,000 to $160,000.
  • FHA loans allow 3.5% down ($28,000), but add mortgage insurance costs that last the life of the loan if you put down less than 10%.
  • VA and USDA loans may require zero down payment, but you must be a veteran or meet rural property and income requirements.
  • Your lender's own rules may require more than the minimum the loan program allows, so comparing lenders matters as much as comparing loan types.
  • Putting down more than the minimum reduces your monthly payment and may lower your interest rate, but it uses cash you might need for closing costs and repairs.

How down payment percentage translates to actual dollars

The percentages lenders quote are straightforward to calculate, but the number that matters is what you actually have to hand over at closing. On an $800,000 purchase price, here is what different percentages mean:

A 3% down payment is $24,000. A 5% down payment is $40,000. A 10% down payment is $80,000. A 15% down payment is $120,000. A 20% down payment is $160,000. These are the amounts you bring to the closing table. They do not include closing costs, which typically run 2% to 5% of the purchase price — another $16,000 to $40,000 you will need.

Many first-time buyers assume the down payment is the only cash they need. It is not. You also pay for the home inspection, appraisal, title search, homeowners insurance, property taxes, and lender fees. Some of these are rolled into your loan, but most are paid at closing. Budget for closing costs separately from your down payment.

Why putting down more changes your monthly payment and interest rate

A larger down payment lowers the amount you borrow, which directly lowers your monthly mortgage payment. If you put down $24,000 on an $800,000 house, you borrow $776,000. If you put down $160,000, you borrow $640,000. The difference in monthly payment is substantial — roughly $800 to $900 per month over a 30-year loan, depending on interest rates.

A larger down payment also often qualifies you for a lower interest rate. Lenders view borrowers who put down 20% or more as lower risk, and they price that into the rate. The difference might be 0.25% to 0.5%, which compounds over 30 years. On a $640,000 loan, a 0.5% rate difference adds up to tens of thousands of dollars in interest.

However, putting down more cash means less cash in your pocket for emergencies, home repairs, or other needs. A roof replacement or foundation repair can cost $15,000 to $30,000. If you put every dollar into your down payment, you may not have reserves when something breaks. Lenders do not penalize you for keeping cash on hand — they only care about the down payment amount and your debt-to-income ratio.

Conventional loans and the 20% threshold

Conventional loans are mortgages not backed by a federal agency. They are the most common type, offered by banks, credit unions, and mortgage companies. Conventional loans allow down payments as low as 3%, but they have a critical threshold at 20%.

If you put down less than 20% on a conventional loan, you pay private mortgage insurance (PMI). PMI is an insurance policy that protects the lender if you stop paying. It costs roughly 0.5% to 1.5% of your loan amount per year, added to your monthly payment. On a $776,000 loan (3% down on $800,000), PMI might add $300 to $400 per month. You pay this until you have paid down the loan to 80% of the original purchase price, which takes years.

If you put down 20% or more, you avoid PMI entirely. This is why 20% is often cited as the "right" down payment — it is the point where you stop paying insurance. However, 20% is not required. Many buyers put down 5% to 10%, accept the PMI cost, and use the cash they save for other purposes. The math depends on your situation.

FHA loans and mortgage insurance that never goes away

FHA loans are mortgages insured by the Federal Housing Administration, a federal agency. They allow down payments as low as 3.5%, making them popular with first-time buyers. On an $800,000 house, 3.5% down is $28,000.

FHA loans have a catch: they require mortgage insurance no matter how much you put down. Unlike conventional PMI, which you can remove once you reach 80% equity, FHA mortgage insurance is permanent. You pay it for the entire 30-year loan. This makes FHA loans more expensive over time, even though the upfront down payment is lower. For an $800,000 house, the difference in total cost between an FHA loan and a conventional loan can be $100,000 or more over 30 years.

FHA loans also have a purchase price limit that varies by county. In many high-cost areas, the limit is $766,550 or higher, but some counties cap it lower. An $800,000 house may exceed the FHA limit in your area, making an FHA loan unavailable regardless of your down payment. Check the FHA loan limit for your county before assuming you can use an FHA loan.

VA and USDA loans for buyers who meet specific requirements

VA loans are available to military veterans, active-duty service members, and some surviving spouses. They require zero down payment. You borrow the full $800,000 and pay no PMI. VA loans also typically offer lower interest rates than conventional loans because the Department of Veterans Affairs guarantees the loan.

USDA loans are available to buyers in rural areas who meet income limits. They also require zero down payment and no PMI. Like VA loans, USDA loans are backed by a federal agency, which lowers the lender's risk and often results in a lower interest rate.

Both programs have trade-offs. VA loans charge a one-time funding fee (typically 1.5% to 3.3% of the loan amount) that is rolled into the loan. USDA loans charge an upfront may provide fee and an annual fee. Neither program allows you to avoid these costs by putting down more money. If you are may be able to access for either program, compare the total cost — including fees and interest — against a conventional loan with a larger down payment before deciding.

What happens if you do not have the down payment yet

If you do not have the full down payment saved, you have several options. You can wait and save more, which delays your purchase but reduces the amount you borrow. You can ask family members for a gift — many lenders allow down payment gifts as long as the giver signs a form stating it is a gift, not a loan. You can use a lower down payment option like FHA or a conventional loan with 3% down, accepting the higher monthly cost.

Some employers and nonprofits offer down payment information programs. These are grants or forgivable loans that help you cover part of the down payment. They are not common for $800,000 houses in high-cost markets, but they exist in some areas. Your local housing authority or a nonprofit housing counselor can tell you whether programs are available in your area.

Avoid taking out personal loans or credit card cash advances to fund your down payment. Lenders look at your total debt when they decide how much to lend you. New debt can lower the amount you may have access to for or raise your interest rate. If you borrow money for the down payment, the lender may require you to disclose it, and it will count against you.

Frequently Asked Questions

Can I put down less than 3% on an $800,000 house?

Conventional loans typically require at least 3% down. Some lenders offer 2% down programs, but they are rare and usually require excellent credit and a low debt-to-income ratio. FHA loans allow 3.5% down. VA and USDA loans allow zero down if you are may be able to access. Below 3%, your options are very limited.

Does the down payment affect my interest rate?

Yes. Larger down payments often may have access to for lower interest rates because you are borrowing less and the lender sees you as lower risk. The difference is typically 0.25% to 0.5%, but it varies by lender and market conditions. Always ask your lender what rate you may have access to for at different down payment levels.

What if I put down 15% instead of 20%?

You will pay PMI on a conventional loan, adding roughly $200 to $300 per month to your payment. You will pay PMI until your loan balance drops to 80% of the original purchase price. Over time, this costs thousands of dollars, but it may be worth it if you need to keep cash on hand for other expenses.

Is a down payment gift counted as income?

No. A down payment gift from a family member is not counted as income and does not affect your debt-to-income ratio. The lender will ask for a gift letter stating the money is a gift, not a loan you have to repay. The gift giver does not need to be on the loan.

Can I borrow my down payment from my 401(k)?

You can borrow from a 401(k) through a loan provision, but it is risky. If you leave your job, the loan becomes due when ready. If you cannot repay it, it is treated as a withdrawal and you owe income tax plus a 10% penalty. Talk to a tax professional before borrowing from retirement savings for a down payment.
