Forty-year mortgages are house loans that are planned to be paid off over a period of 40 years. Their longer repayment period enables them to make lesser monthly payments. The trade-off is greater interest charges throughout the loan's term.

Key Takeaways

  • Many major banks and lenders, notably the Federal Housing Administration (FHA), do not make loans for more than 30 years.
  • Lower monthly payments on a 40-year mortgage can help you finance a more costly home and improve your cash flow.
  • These loans often have higher interest rates, and you will pay significantly more in interest over the course of 40 years than you would for a shorter-term loan.


Most mortgages are for 15 or 30 years; a 40-year mortgage is uncommon. However, because the loan is ten years longer, the monthly payments on a 40-year mortgage are lower than those on a 30-year loan—and much lower when compared to a 15-year loan. Because of the lower payments, these lengthier loans are appealing to purchasers who:
  • Want the smallest monthly payments possible
  • Have cash flow problems
  • Are you trying to stretch to get into a more expensive house?
40-year mortgages are harder to find since they are less popular. A 40-year Federal Housing Administration (FHA) loan is not available, and many larger lenders do not give loans greater than 30 years. If you discover one, you'll need strong credit to qualify for it, and the interest rate on these loans may be higher as well.


The primary benefit of 40-year loans is a lower monthly payment. Stretching the loan over 40 years rather than 30 years may allow you to buy multiple properties, which can be beneficial for homeowners looking to optimize their housing funds by qualifying for as many houses as possible. Some 40-year loans are the result of loan modifications, which are processes in which the lender and borrower collaborate to restructure the debt and retain the borrower in his house following a financial setback.


Lower monthly payments may be appealing, but there are always consequences. A 40-year mortgage requires you to pay more interest and create equity more slowly. Using a loan amortization calculator, you can see how the overall interest expenses for a 40-year loan are greater. The longer the time range, the higher the interest rate. 40-year mortgages have hefty interest rates as well. Expect to pay an additional. Twenty-five percent or more than on a 30-year mortgage. If you're considering a 40-year mortgage, consider whether you're trying to acquire more houses than you can afford.

Comparing 30-Year to 40-Year Mortgages

When you talk about the term length of a mortgage, you're talking about how long it will take to pay off the debt. You pay some interest and a portion of the loan total with each monthly payment. In the last year of a 40-year fixed-rate mortgage, your final payment will totally pay off the debt. The process of repaying a debt is known as "amortisation." When you adjust one portion of a loan, you change how quickly it will amortize (the interest rate or length of time to repay it, for example). The debt amortizes more slowly when the time term is extended. Calculate your monthly payments to see how they differ between a 15-year, 30-year, and 40-year mortgage. Assume you want to borrow $200,000 to purchase a home. A 40-year loan at 4.5 percent would cost $899 each month. If the duration was reduced from 40 to 30 years, it would cost $1,013 per month or $114 more. However, if you examine closely, the 40-year loan would cost you $431,580 in principle and interest over the life of the loan, while the 30-year loan will cost you $364,813—$66,767 less. Calculate Your Monthly Payment Your monthly mortgage payment will be determined by the following factors: home price, down payment, loan length, property taxes, homeowners insurance, and loan interest rate (which is highly dependent on your credit score).  

Where to Find a 40-Year Mortgage

According to the Consumer Financial Protection Bureau (CFPB), qualifying mortgages (QM) must have a length of no more than 30 years, making 40-year loans unqualified mortgages. A qualifying mortgage is one that fulfills specific CFPB guidelines aimed at ensuring that you can afford the loan. Unqualified mortgages may still be acceptable for your borrowing position, but because large lenders don't consider them as safe as other loans, they're not as readily available. (Jumbo loans are another sort of unqualified mortgage that is still available under the right conditions.) Before the 2008 mortgage crisis, products like the 40-year mortgage were simpler to locate; currently, they account for a minuscule proportion of all loans granted in the United States. Because 40-year mortgages are uncommon, they need a bit of extra searching. They are most likely to be found with smaller, private lenders and credit unions, and they are more likely to be found in areas with exceptionally hot and costly real estate markets (such as in California).


A 40-year mortgage might be ideal for you. You may decide that it is the best alternative if you do your research and work closely with your lender. However, before proceeding, you should explore certain possibilities and rule them out. Interest-only loans may achieve similar results as a 40-year mortgage, depending on your goals and credit. Depending on the market, you may have a better chance of securing an interest-only loan or a 40-year mortgage. Before making a selection, look at what the banks have to offer. You should also think about borrowing less and taking for a shorter-term loan. It's simpler to get into difficulty later if you stretch to buy more than you should. Make sure you leave some room in your budget for unforeseen costs down the line.

Frequently Asked Questions (FAQs)

What is the average length of a mortgage?

A 30-year fixed-rate mortgage is the most common form of house loan in the United States. However, most homeowners will refinance or sell well before the loan period is finished, bringing the average mortgage length to slightly under ten years.

What is the best length of time for a mortgage?

There is no one ideal mortgage term length. The best terms are determined by your financial situation, age, and financial objectives. A 15-year mortgage will save you money in the long term, but it will be useless if you cannot manage the high monthly payment. A 30-year mortgage will reduce your monthly payments and allow you to invest the surplus funds elsewhere, but you will pay more in interest over time. Before deciding on mortgage conditions, thoroughly consider your financial circumstances.
