What is a conventional home loan?
A conventional loan is any type of home loan that isn’t insured or guaranteed through a government agency. Some quick facts:
They often follow government-set rules: Many conventional loans conform to government-set loan limits as well as income and credit score minimums.
They tend to cost less: Conventional loans are often less expensive than government-backed mortgages such as FHA loans (insured by the Federal Housing Administration).
They’re tougher to qualify for: Conventional loan requirements, such as credit score and debt-to-income (DTI) ratio, are generally stricter than government-backed loan programs. Most lenders require at least a 620 minimum credit score to qualify, higher scores typically get better interest rates.
Common types of conventional loans
1. Conforming conventional loans
If a conventional loan is less than the maximum loan amount set by the Federal Housing Finance Agency and meets additional loan standards set by Fannie Mae or Freddie Mac, it’s called a conforming loan. Because Fannie and Freddie are government-sponsored enterprises, you may also hear conforming loans referred to as “GSE loans.”
2. Nonconforming conventional loans
If a conventional loan exceeds FHFA loan limits or uses underwriting standards that are different from those set by Fannie Mae and Freddie Mac, it’s called a nonconforming loan. A jumbo loan is a common type of nonconforming conventional loan. You may need a jumbo loan to finance more than $832,750 in most U.S. counties.
3. Fixed-rate conventional loans
Whether they’re conforming or nonconforming, all mortgages require you to pay interest. With a fixed-rate conventional loan, the interest rate stays the same for as long as you have the mortgage. Many buyers choose a 30-year fixed-rate conventional mortgage, but shorter terms are also available.
4. Adjustable-rate conventional loans
The alternative to a fixed-rate mortgage is an adjustable-rate mortgage, or ARM. Conventional loans with adjustable rates, also known as hybrid ARMs, have rates that may go up or down over time. ARM rates usually adjust annually, after an initial fixed-rate period of three, five, seven or 10 years.
5. Low-down-payment conventional loans
Despite what you may have heard, you don’t need to put 20% down to buy a house. In fact, the average down payment on a house might be lower than you think: First-time buyers typically put 10% down, according to the National Association of Realtors.
HomeReady and Home Possible are conventional mortgage options that allow down payments as low as 3%, sometimes referred to as "3 down conventional loans." If you qualify for a 3% down payment through one of these programs, you’ll need to finance the other 97%. That’s why you may also hear them called “conventional 97 loans.”
Your down payment will also affect your loan-to-value (LTV) ratio, which measures what percentage of the home's value you’re financing with a mortgage. A higher LTV typically means higher risk to the lender and may require private mortgage insurance.
6. Conventional renovation loans
It can be hard to find the perfect house for your budget. Buying a fixer-upper is one way to achieve home ownership when prices are high or move-in-ready inventory is low.
The CHOICERenovation loan and HomeStyle loan are two types of conventional mortgages that allow you to finance a home purchase, as well as the necessary renovations, at the same time.
