There can be some exceptions if the corporation is partially owned by the government. Sometimes it is difficult to understand the difference between the types of mortgages and loans because each type has different meaning and purpose.
To be qualified as Conventional Mortgage, it must be provided by a private lender. There are many options available including banks and credit unions. You can also get them from Federal Home Loan Mortgage Corporation and Federal National Mortgage Association which are renowned government backed companies. Sometimes people confuse them with conforming loans. It is understandable why this can be confusing, that is why the following difference will help you differentiate both these types easily.
A Conforming Loan or Mortgage is the one which can be secured if a person meets a certain criterion for the funding of loans. If total mortgage or loan secured exceeds $484,350, then it is a conventional loan, but if the total loans provided is less $484,350 then it is a Conforming Loan because it does not exceed the limit set by the above-mentioned mortgage providers.
