Mortgages may also be either “conventional” (meaning funded by the private sector – usually a bank) or a “government-backed” loan. Government-backed loans are backed by the federal government, including the Department of Veteran Affairs or the Department of Housing and Urban Development. The government agency is “insuring” the loan, although the funding may still be by a bank.
So why the two different types of loans? The Department of Housing and Urban Development typically has less-stringent lending qualifications, making it easier for some buyers to get a loan. For example, at the time of this writing, the down payment on an FHA loan (by the Federal Housing Administration) can be as low as 3.5% as opposed to a private loan which require 10-20%.
FHA loans, VA loans, and USDA loans are all examples of government-backed loans.
