A conventional loan is any mortgage loan that is not insured or guaranteed by the government (such as under Federal Housing Administration, Department of Veterans Affairs, or Department of Agriculture loan programs).
Advantages of conventional loans include low interest rate, higher loan limits, flexibility, no PMI if LTV is less than 80%.
The Federal Housing Administration (FHA) - which is part of HUD - insures the loan, so your lender can offer you a better deal.
FHA allows a buyer to purchase a home with as little as 3.5% down. They tend to be more lenient on areas such as credit, funds to close and co-borrowers.
Benefits of FHA loans are low down payments, low closing costs, easy credit qualifying.
VA mortgage loans extend to not only the Army, Navy, Air Force and Marines but also to Reservists and National Guardsmen.
The VA Mortgage Loans is guaranteed for no money down up to $510,400.
Many VA Mortgage Loans are assumable.
It is easier to qualify for a VA Loan than a conventional loan.
