You can buy a home with less than 20 percent down, and most lower-income buyers do

The 20 percent down payment rule is a myth that keeps people renting. Most homebuyers put down between 3 and 10 percent, and several loan programs let you go lower. The real question is not whether you can afford less — it is which path costs you the least money over time and which one you can actually save for.

A smaller down payment means a larger loan, which means higher monthly payments and more interest paid overall. But it also means you can buy sooner, build equity now instead of later, and stop paying rent to a landlord. The trade-off depends on your income, your local rent, how stable your job is, and how much you have saved.

Key Takeaways

  • Federal Housing Administration (FHA) loans let you put down as little as 3.5 percent, and some state and local programs go lower or require nothing down.
  • A smaller down payment means you pay mortgage insurance (either upfront or monthly), which adds to your total cost but lets you buy sooner.
  • Your monthly payment depends on the loan amount, interest rate, and loan term — a lower down payment raises the payment, but a better interest rate can offset that.
  • Saving even a small down payment (3 to 5 percent) is usually faster than saving 20 percent, and you start building equity years earlier.
  • Down payment assistance programs exist in most states and counties, and some do not require you to repay them.

How down payment size affects your monthly payment and total cost

The down payment is the money you bring to closing. The rest of the purchase price becomes your loan. If a home costs $200,000 and you put down $10,000, you borrow $190,000. If you put down $40,000, you borrow $160,000. The smaller the down payment, the larger the loan, and the larger your monthly payment.

A smaller down payment also triggers mortgage insurance, which protects the lender if you stop paying. With an FHA loan, you pay an upfront insurance premium (usually 1.75 percent of the loan amount, added to what you borrow) plus a monthly insurance payment. With a conventional loan, you pay private mortgage insurance (PMI) monthly until you have paid down the loan to 80 percent of the home's value. Both add hundreds of dollars per year to your cost.

Over 30 years, a lower down payment can cost you tens of thousands of dollars more in interest and insurance. But you also stop paying rent immediately and start building equity in a home you own. For someone paying $1,200 a month in rent, buying with 5 percent down might cost $1,400 a month in mortgage, insurance, taxes, and maintenance — but that $1,400 goes toward ownership, not a landlord's profit.

FHA loans: the most common path for lower-income buyers

FHA loans are backed by the Federal Housing Administration and are designed for buyers who cannot save 20 percent. The minimum down payment is 3.5 percent. You need a credit score of at least 580 to may have access to (some lenders require 620), and your debt-to-income ratio cannot exceed 43 percent — meaning your total monthly debt payments (car loans, credit cards, student loans, and the new mortgage) cannot be more than 43 percent of your gross monthly income.

The upfront mortgage insurance premium on an FHA loan is 1.75 percent of the loan amount and is usually rolled into your loan, so you pay it over time with interest. You also pay an annual mortgage insurance premium (between 0.55 and 0.80 percent of the loan amount per year, depending on your down payment and loan term) as part of your monthly payment. This insurance stays on the loan for the full 30 years if you put down less than 10 percent.

FHA loans are offered by banks, credit unions, and mortgage companies. You apply through a lender, not directly to the government. The process is the same as a conventional loan: you get preapproved, make an offer, get a home inspection, and close. The main difference is the lower down payment requirement and the mortgage insurance that comes with it.

Conventional loans with low down payments

Conventional loans (not backed by the government) typically require 5 to 20 percent down, though some lenders offer 3 percent down programs. They usually require a credit score of 620 or higher and a debt-to-income ratio under 43 percent. Private mortgage insurance (PMI) is required if you put down less than 20 percent, and it stays on the loan until you have paid it down to 80 percent of the home's value — which can take 10 to 15 years.

PMI is usually cheaper than FHA mortgage insurance, especially if you put down 10 percent or more. But conventional loans often have stricter income and credit requirements than FHA loans, and some lenders will not work with buyers who have recent late payments, collections, or bankruptcy. If your credit is damaged or your income is irregular, an FHA loan may be your only option.

State and local down payment assistance programs

Most states and many counties offer down payment assistance to lower-income buyers. These programs vary widely: some give you a grant (money you do not repay), some offer a forgivable loan (you repay it only if you sell or refinance within a set time), and some offer a second mortgage at a low or zero interest rate. Some programs have no income limit; others cap your household income at 80 or 100 percent of the area median income.

Common programs include state housing finance agencies (search "[your state] housing finance agency"), community development corporations, and nonprofit lenders. Many require you to take a homebuyer education course, which usually costs $50 to $150 and can be taken online. Some programs are tied to specific lenders or specific neighborhoods, so availability depends on where you want to buy.

The fastest way to find programs in your area is to contact your local housing authority or call 211 (a free referral line). They can tell you which programs are currently open, what income and credit requirements apply, and whether you need to use a specific lender. Many programs run out of funding and reopen later in the year, so if you are told a program is closed, ask when it reopens.

Saving for a down payment versus using assistance

If you have time and stable income, saving 3 to 5 percent is usually faster than saving 20 percent. At $500 a month, you can save $15,000 in 30 months — enough for a 5 percent down payment on a $300,000 home. Saving $60,000 for 20 percent would take 10 years. In those 10 years, rent increases, home prices rise, and you build no equity.

Down payment assistance programs can cut years off that timeline. If you find a grant program, you may not have to save anything. If you find a forgivable loan program, you get the down payment now and repay it only if you sell within five or seven years — by which time you may have built enough equity to cover it. Even a second mortgage at 0 percent interest lets you buy sooner and start building equity while you pay it back slowly.

The trade-off is that assistance programs have waiting lists, income limits, and credit requirements. Some require you to buy in a specific neighborhood or use a specific lender. If you do not meet the requirements or the program is closed, saving on your own may be your only option — but even then, 3 to 5 percent is a realistic goal.

How to decide what down payment makes sense for you

Start by calculating what you can actually save in the next 12 to 24 months. If you can save $10,000, that is your realistic target, not 20 percent. Then find out what loan programs you may have access to for: get preapproved for an FHA loan and a conventional loan, and check what down payment assistance programs exist in your area. Preapproval is free and does not commit you to anything.

Compare the total cost of each path over 10 years, not just the monthly payment. A smaller down payment means a higher payment and more insurance, but you buy sooner and build equity faster. A larger down payment means a lower payment, but you rent longer and build no equity. For most lower-income buyers, buying sooner with a smaller down payment costs less overall than waiting to save 20 percent.

Talk to a mortgage lender or a nonprofit housing counselor (many offer free consultations) about your specific situation. They can run the numbers for you and show you what each down payment amount would cost per month and over the life of the loan. This is the only way to know whether 3 percent, 5 percent, or 10 percent makes sense for your income and your timeline.

Frequently Asked Questions

What is the absolute minimum down payment I can put down?

FHA loans allow 3.5 percent down with a credit score of 580. Some state and local programs go lower or require nothing down, but availability varies by location. Contact your local housing authority or call 211 to find programs in your area.

Will a smaller down payment hurt my chances of getting approved?

No. Lenders expect lower down payments on FHA loans and have underwriting standards built around them. Your credit score, income, and debt-to-income ratio matter more than the down payment amount. A 3.5 percent down payment on an FHA loan is as standard as a 20 percent down payment on a conventional loan.

Can I use a gift from family for my down payment?

Yes, but lenders require a gift letter stating that the money is a gift, not a loan you have to repay. The letter must be signed by the person giving you the money and include their relationship to you. Some lenders limit how much of your down payment can be a gift; FHA loans typically allow 100 percent gift funds.

How long does mortgage insurance stay on my loan?

On FHA loans with less than 10 percent down, mortgage insurance stays for the full 30-year loan term. On conventional loans, PMI stays until you have paid the loan down to 80 percent of the home's value, which usually takes 10 to 15 years. You can also remove PMI by refinancing once you have built enough equity.

Should I wait and save more for a bigger down payment?

Not usually. Waiting five years to save 20 percent means five years of rent with no equity. Buying now with 5 percent down and mortgage insurance costs less overall because you start building equity immediately and can refinance to remove insurance once you have paid down the loan. Run the numbers with a lender to compare your specific situation.
