Mortgage Types Compared: Fixed, ARM, FHA, VA, and USDA Loans

Selecting the right mortgage is one of the most critical decisions in the home buying process. With so many loan options available, each with its own terms, requirements, and advantages, it can be overwhelming to determine which one is best for your situation. This comprehensive guide compares the most common mortgage types, explaining how each works, who it is best suited for, and the pros and cons of each option.

Fixed-Rate Mortgages

A fixed-rate mortgage locks in your interest rate for the entire term of the loan, which is typically 15 or 30 years. This means your principal and interest payment remains the same every month for the life of the loan, providing predictable housing costs that make budgeting simple and straightforward.

30-Year Fixed-Rate Mortgage

The 30-year fixed is the most popular mortgage product in the United States. It offers the lowest monthly payment among fixed-rate options because the loan is spread over a longer period. However, you pay significantly more in total interest over the life of the loan compared to a shorter-term mortgage. For example, on a $300,000 loan at 6.5 percent interest, a 30-year fixed results in approximately $382,000 in total interest, while a 15-year fixed results in approximately $160,000. The 30-year fixed is best for buyers who want the lowest possible monthly payment and plan to stay in their home for many years.

15-Year Fixed-Rate Mortgage

The 15-year fixed-rate mortgage offers a lower interest rate than the 30-year fixed, typically 0.5 to 0.75 percent lower, because the lender takes on less risk with a shorter repayment period. The trade-off is a higher monthly payment, but you build equity faster and pay significantly less interest over the life of the loan. This option works best for buyers who can afford the higher payment and want to pay off their home quickly while saving money on interest.

Adjustable-Rate Mortgages (ARMs)

An adjustable-rate mortgage, or ARM, starts with a lower fixed interest rate for an initial period, typically 5, 7, or 10 years. After this initial period, the rate adjusts periodically based on market conditions, which can cause your monthly payment to increase or decrease. ARMs are expressed as ratios like 5/1, 7/1, or 10/1, where the first number indicates the initial fixed period and the second number indicates how often the rate adjusts after that.

How ARMs Work

During the initial fixed period, an ARM functions exactly like a fixed-rate mortgage with a set interest rate and payment. Once the fixed period ends, the rate adjusts annually based on a financial index plus a margin set by the lender. Most ARMs have caps that limit how much the rate can increase at each adjustment and over the life of the loan, providing some protection against dramatic payment increases. For example, a 5/1 ARM might start at 5.5 percent for five years, then adjust to 6.5 percent in year six if market rates have risen. ARMs are best for buyers who plan to sell or refinance within the initial fixed period, or who expect their income to increase significantly in the coming years.

FHA Loans

FHA loans are insured by the Federal Housing Administration and are designed to help borrowers who may have difficulty qualifying for conventional financing. These loans are particularly popular with first-time buyers and those with lower credit scores or limited savings for a down payment.

FHA Loan Requirements and Benefits

FHA loans require a minimum down payment of just 3.5 percent for borrowers with credit scores of 580 or higher. For credit scores between 500 and 579, a 10 percent down payment is required. Credit score requirements are more lenient than conventional loans, making FHA loans accessible to borrowers who might otherwise be denied financing. FHA loans allow gift funds for the down payment, and the seller can contribute up to 6 percent of the purchase price toward the buyer's closing costs. The main drawback is the mortgage insurance premium (MIP), which includes an upfront fee of 1.75 percent and an annual premium that cannot be removed for the life of the loan in most cases. FHA loans are best for buyers with lower credit scores, limited savings, or those who need more flexible qualification requirements.

VA Loans

VA loans are guaranteed by the Department of Veterans Affairs and are available to active-duty service members, veterans, and eligible surviving spouses. VA loans offer some of the most favorable terms available in the mortgage market, making them an excellent option for those who qualify.

VA Loan Benefits

The most significant advantage of a VA loan is that it requires no down payment at all. There is no private mortgage insurance requirement, which saves borrowers hundreds of dollars per month compared to conventional and FHA loans. VA loan interest rates are typically lower than conventional rates, and the credit requirements are more flexible. To qualify, you need a Certificate of Eligibility (COE) from the VA, which verifies your service history and eligibility. VA loans do have a funding fee that varies based on your down payment and whether this is your first VA loan, but this fee can be financed into the loan amount. VA loans are the best option for eligible military members and veterans who want the lowest possible costs and easiest qualification requirements.

USDA Loans

USDA loans are backed by the United States Department of Agriculture and are designed to promote homeownership in rural and some suburban areas. Like VA loans, USDA loans offer zero-down-payment financing, making them an attractive option for eligible buyers.

USDA Loan Requirements

To qualify for a USDA loan, the property must be located in a USDA-eligible area, and your household income must not exceed 115 percent of the median income for the area. The USDA uses a guarantee fee system similar to FHA mortgage insurance, with an upfront fee of 1 percent and an annual fee of 0.35 percent. Interest rates on USDA loans are typically competitive with FHA and conventional rates, and credit requirements are relatively flexible, with minimum scores typically around 640. USDA loans are best for buyers willing to look in rural or suburban areas who want zero-down-payment financing and can meet the income and location requirements.

Choosing the Right Mortgage for You

The best mortgage for you depends on your financial situation, your plans for the home, and your risk tolerance. If you want predictable payments and plan to stay in the home long-term, a fixed-rate mortgage is likely the best choice. If you plan to sell or refinance within a few years and want the lowest initial rate, an ARM might save you money. If you have a lower credit score or limited savings, FHA loans provide accessible financing. If you are an eligible veteran or service member, a VA loan offers the best overall terms. If you are looking in a rural or suburban area and can meet the income requirements, a USDA loan provides zero-down-payment financing with competitive rates. Your mortgage lender and real estate agent can help you evaluate your options and choose the loan that best fits your needs.

Frequently Asked Questions

Can I switch from one mortgage type to another after closing?

You can refinance your mortgage at any time, which allows you to switch from one loan type to another. For example, you might start with an FHA loan and later refinance to a conventional loan once you have built enough equity to eliminate mortgage insurance. However, refinancing involves closing costs and qualification requirements, so it is not a decision to make lightly.

What credit score do I need for each loan type?

Credit score requirements vary by loan type. Conventional loans typically require a minimum score of 620, with the best rates going to borrowers with scores of 740 or higher. FHA loans allow scores as low as 500 with a 10 percent down payment or 580 with 3.5 percent down. VA loans have no official minimum, but most lenders require at least 620. USDA loans typically require a minimum score of 640.

Which mortgage type has the lowest total cost?

The total cost of a mortgage depends on the interest rate, loan term, down payment, and any additional fees or insurance. A 15-year fixed-rate mortgage typically has the lowest total cost because of the shorter term and lower interest rate. However, the monthly payment is higher. The best way to compare total costs is to look at the annual percentage rate (APR), which includes the interest rate plus other loan costs like mortgage insurance and origination fees.
