The conventional conforming loan is the traditional mortgage program. It is called “conforming” because it fits within the standardized guidelines set by Fannie Mae and Freddie Mac. It can be used to finance all different types of residential properties. The loan requires mortgage insurance if the down payment is less than 20 percent. The monthly mortgage insurance required for this loan is cheaper than FHA mortgage insurance. A conventional loan caters to those who have more money to put down & great credit scores.
