What a low down payment mortgage is and who uses them

A low down payment mortgage is a home loan where you put down less than 20 percent of the purchase price upfront. Instead of saving $80,000 to buy a $400,000 house, you might put down $10,000 to $40,000 and borrow the rest. The lender accepts the smaller down payment because you agree to pay mortgage insurance — a monthly fee that protects the lender if you stop paying.

Most first-time buyers use low down payment mortgages because saving 20 percent takes years. A conventional loan with 3 to 5 percent down, an FHA loan with 3.5 percent down, or a VA loan with zero down are the most common routes. Each has different insurance costs, credit score requirements, and rules about what kind of property you can buy.

The trade-off is straightforward: you get into a home sooner, but you pay more over time because of the insurance premium. A $300,000 mortgage with 5 percent down costs roughly $100 to $200 more per month than the same mortgage with 20 percent down, depending on your credit score and the loan type.

Key Takeaways

  • Low down payment mortgages let you buy with 3 to 5 percent down instead of 20 percent, but you pay monthly mortgage insurance until you build equity.
  • FHA loans require 3.5 percent down and accept lower credit scores, while conventional loans with 3 to 5 percent down usually need a score of 620 or higher.
  • Mortgage insurance costs $100 to $300 per month on a typical loan and is built into your monthly payment, not a separate bill.
  • You can stop paying mortgage insurance once you own 20 percent of the home's value, which typically takes 8 to 12 years of regular payments.
  • The total cost of a low down payment mortgage is higher than putting 20 percent down, but the monthly payment is lower than renting in many markets.

How mortgage insurance works and what it costs

Mortgage insurance protects the lender, not you. If you stop paying and the lender forecloses and sells the house for less than you owe, the insurance covers the difference. You pay for this protection as a monthly premium added to your mortgage payment.

The cost depends on three things: how much you borrowed, how much you put down, and your credit score. On a $300,000 loan with 5 percent down and a 680 credit score, mortgage insurance might run $150 to $200 per month. The same loan with a 750 credit score might be $100 to $130 per month. With 10 percent down, the cost drops to $80 to $120 per month.

FHA loans charge mortgage insurance in two pieces: an upfront fee (usually 1.75 percent of the loan amount, rolled into what you borrow) and a monthly premium (0.55 to 0.80 percent of the loan annually, depending on the loan term and how much you put down). Conventional loans with low down payments charge only a monthly premium, with no upfront fee.

You cannot avoid mortgage insurance on a low down payment loan — it is required by law. You can only stop paying it once you own enough of the home. On a conventional loan, you can request to cancel it once you reach 20 percent equity (you have paid down the loan to 80 percent of the original purchase price). On an FHA loan, mortgage insurance stays for the life of the loan if you put down less than 10 percent.

Conventional loans versus FHA loans

A conventional mortgage is a loan that is not backed by a government agency. You can get one with 3 to 5 percent down, but most lenders require a credit score of 620 or higher and a debt-to-income ratio below 43 percent (your monthly debt payments divided by your gross monthly income). The monthly mortgage insurance is lower than FHA insurance if your credit score is good.

An FHA loan is backed by the Federal Housing Administration, which means the government guarantees part of the loss if you default. FHA loans accept credit scores as low as 500 to 580 and allow higher debt-to-income ratios — up to 50 percent in some cases. The upfront mortgage insurance fee is higher, and the monthly premium stays for the life of the loan if you put down less than 10 percent, which makes FHA more expensive long-term for most borrowers.

Choose a conventional loan if your credit score is 640 or higher and you have steady income. Choose an FHA loan if your credit score is below 620, you have had recent credit problems, or you cannot save 5 percent down. The monthly payment will be similar, but the total cost over 30 years will be lower with a conventional loan if you plan to stay in the home.

VA loans and USDA loans for specific borrowers

If you are a current or former member of the military, a VA loan lets you buy with zero down payment and no mortgage insurance. You pay a one-time funding fee (1.4 to 3.6 percent of the loan amount, depending on your service history and down payment) instead. VA loans have no credit score minimum, though most lenders require 620 or higher in practice.

If you are buying in a rural area and your household income is below the area median, a USDA loan also offers zero down and no mortgage insurance. You pay an upfront may provide fee (1 percent of the loan) and an annual fee (0.35 percent of the loan balance each year). USDA loans require a credit score of 640 or higher and are limited to properties in designated rural areas.

Both VA and USDA loans have lower total costs than conventional or FHA loans because there is no monthly mortgage insurance. However, they are only open to borrowers who meet specific requirements. If you do not may have access to for either, a conventional loan with 5 percent down is usually cheaper than an FHA loan.

What happens when you reach 20 percent equity

On a conventional loan, you can request to cancel mortgage insurance once you own 20 percent of the home — meaning you have paid the loan down to 80 percent of the original purchase price. This usually takes 8 to 12 years of on-time payments, depending on the interest rate and loan term.

The lender is required to cancel mortgage insurance automatically once you reach 22 percent equity (78 percent loan-to-value), even if you do not ask. Some lenders will cancel at 20 percent if you request it in writing and your account is in good standing. Check your loan documents or call your lender to find out their policy.

On an FHA loan, mortgage insurance does not go away. If you put down less than 10 percent, you pay it for the entire 30-year loan term. If you put down 10 percent or more, mortgage insurance drops off after 11 years. This is one reason FHA loans are more expensive over time — the insurance cost never ends for most borrowers.

How to compare total costs across loan types

The monthly payment is only part of the cost. To compare loans fairly, calculate the total amount you will pay over 30 years, including mortgage insurance, property taxes, homeowners insurance, and interest.

Use a mortgage calculator that includes mortgage insurance. Enter the loan amount, down payment, interest rate, and loan term. The calculator will show you the monthly payment with insurance included. Then multiply the monthly payment by 360 (the number of months in a 30-year loan) to see the total cost.

Compare at least three scenarios: a conventional loan with 5 percent down, an FHA loan with 3.5 percent down, and a conventional loan with 10 percent down (if you can save that much). The difference in total cost is often $50,000 to $100,000 over 30 years, so the choice matters. A lower monthly payment now can mean thousands more in interest and insurance later.

Common mistakes to avoid

Do not assume mortgage insurance is temporary. On an FHA loan with less than 10 percent down, it is permanent. Budget for it as part of your monthly housing cost, not as something that disappears in a few years.

Do not ignore your credit score. A 50-point difference in your credit score can change your mortgage insurance premium by $50 to $100 per month. If your score is below 640, spend three to six months paying down debt and making on-time payments before you explore. The savings will be worth the wait.

Do not borrow the maximum you are approved for. Just because a lender will lend you $400,000 does not mean you should borrow it. Your monthly payment, property taxes, insurance, and mortgage insurance together should not exceed 28 to 30 percent of your gross monthly income. Going higher puts you at risk if your income drops or expenses rise.

Do not skip the appraisal or inspection. If the house appraises for less than the purchase price, your down payment percentage drops and your mortgage insurance cost rises. An inspection can reveal problems that cost thousands to fix, which changes whether the deal makes sense.

Frequently Asked Questions

Can I get a low down payment mortgage with bad credit?

FHA loans accept credit scores as low as 500 to 580, though most lenders require 580 or higher in practice. Conventional loans typically require 620 or higher. If your score is below 580, an FHA loan is your best option, but expect higher mortgage insurance costs and a higher interest rate.

What is the difference between mortgage insurance and homeowners insurance?

Mortgage insurance protects the lender if you default. Homeowners insurance protects your home and belongings from fire, theft, and weather damage. Both are required if you have a mortgage, and both are separate monthly costs added to your payment.

Can I pay off my mortgage early to stop paying mortgage insurance?

Yes. If you pay down the loan to 80 percent of the original purchase price faster than the regular schedule, you can request to cancel mortgage insurance sooner. However, paying extra principal each month may not be the best use of your money if your interest rate is low — you might earn more by investing the extra money instead.

What if I put down more than 5 percent but less than 20 percent?

Mortgage insurance costs less with a larger down payment. At 10 percent down, insurance is roughly half the cost of 5 percent down. At 15 percent down, it is even lower. If you can save 10 percent, the monthly savings in insurance often justify the extra time spent saving.

Do I have to use an FHA loan if I am a first-time buyer?

No. First-time buyer status does not require FHA. You can use a conventional loan with 3 to 5 percent down if your credit score is 620 or higher. Some states and cities offer first-time buyer programs with down payment help, which may lower your out-of-pocket cost more than an FHA loan would.
