A Conventional loan is a mortgage that is not backed by a government agency. Conforming conventional loans follow the lending guidelines set by the Federal National Mortgage Association (FNMA or Fannie Mae) and the Federal Home Loan Mortgage Corporation (FHLMC or Freddie Mac).
You can get a conventional loan with as little as 3% – 5% down, however, if you don’t put at least 20% down, you will be required to pay private mortgage insurance which insures the lender for the equivalent of a 20% down payment in case of default.
It’s possible to get approved for a conventional loan with a credit score as low as 620, many lenders require a credit score of 660-680 or higher.
The interest rate and private mortgage insurance varies based on your credit score. The higher your credit score, the better your interest rate and private mortgage insurance rate.
Conventional loan limits vary by the county in which the property is located. In California, the maximum conventional loan limits range from $647,200 up to $970,300 in the “high cost” counties which include Alameda, Contra Costa, Los Angeles, Marin, Orange, San Benito, San Francisco, Santa Clara and Santa Cruz.
