A conventional mortgage is a home loan backed by Fannie Mae or Freddie Mac, the two government agencies that make up the Federal Housing Finance Agency (FHFA).

A Longer Definition: Conventional Mortgage

Conventional mortgages, broadly, are mortgages backed by government agencies Fannie Mae or Freddie Mac. Fannie Mae and Freddie Mac are the two mortgage entities that make up the Federal Housing Finance Agency. Conventional mortgages are split into two categories: Conforming and Non-Conforming. A conforming mortgage is a conventional mortgage that conforms to the FHFA's published mortgage guidelines and falls within conforming mortgage loan limits for the area. After a conforming mortgage is originated for a home buyer, the mortgage is routed through Fannie Mae or Freddie Mac and then purchased on Wall Street as mortgage-backed securities. A non-conforming mortgage is a conventional mortgage that exceeds loan mortgage loan limits and, therefore, cannot be purchased by the FHFA. Non-conforming mortgages are commonly called jumbo mortgages. The FHFA modifies conforming mortgage loan limits annually to match changes in its House Price Index, a home-value tracker that measures home prices in more than 3,100 local markets. The current conforming loan limit for single-family homes, including detached homes, townhomes, and condos, is $766,550and ranges up to $1,149,825in high-cost areas of the country. 2,847,000people used conventional mortgages to buy a home last year. Other conventional mortgage statistics include:

• The conventional mortgage market share was 81%
• The average conventional loan size was $375,000
• 87%of home buyers using a conventional mortgage purchased a 1-unit home Conventional mortgages are commonly available with 30-year, 20-year, 15-year, and 10-year fixed-rate options and adjustable-rate options, including 3-year, 5-year- and 7-year ARMs.

Who Qualifies for a Conventional Mortgage?

To qualify for a conventional mortgage, first-time home buyers must meet Fannie Mae's or Freddie Mac's eligibility standards, which are nearly identical for buyers of 1-unit homes, including detached houses, condominiums, townhomes, and row homes.

• Home buyers must make a down payment of at least 3 percent
• Home buyers must have a verified source of income
• Home buyers must have a minimum credit score of 620
• Home buyers may not have a recent foreclosure, short sale, or bankruptcy
• The mortgage loan size must be within local mortgage loan limits
• Homes must be structurally sound and habitable In rare scenarios, a home buyer will be approved for a conventional mortgage despite not meeting official mortgage standards. Conventional mortgages require home buyers to have a social security number or valid Individual Taxpayer Identification Number (ITIN). Permanent and non-permanent resident aliens are eligible for conventional mortgages at the same terms as U.S. citizens. Conventional mortgages are the most widely used mortgage program nationwide. More home buyers use conventional mortgages than all other mortgage types combined.

Private Mortgage Insurance (PMI) for Conventional Mortgages

Private mortgage insurance (PMI) is to conventional mortgages what FHA mortgage insurance is to FHA mortgages: an insurance policy that pays mortgage lenders when a homeowner has a mortgage default from not making payments. It's customary for mortgage lenders to order private mortgage insurance on behalf of a home buyer. Policies are primarily identical in price and coverage, which is based on traits including down payment size, credit score, size of down payment, and mortgage program. The typical private mortgage insurance fee is between 0.25 and 1.00 percent per year. Private mortgage insurance rates are lower for home affordability mortgage programs like HomeReady and Home Possible than a standard conventional loan. Payments are also lower for fixed-rate mortgages compared to adjustable-rate mortgages. Generally, a conventional mortgage requires private mortgage insurance until the homeowner's equity reaches twenty percent. Therefore, for many first-time home buyers, PMI goes away quickly. Most first-time buyers can cancel PMI in fewer than three years. Here's why: The value of a U.S. home goes up approximately 7 percent per year, and with every mortgage payment, a homeowner's PITI reduces their mortgage balance. Therefore, a home buyer who starts with five percent down would need roughly 27 months to reach 80% loan-to-value. It's common for first-time home buyers to delay buying a home because they want to avoid paying private mortgage insurance. This is one of the 21 mistakes that first-time buyers make.
