Conventional loans are mortgage loans offered by non-government sponsored lenders. A conventional, or conforming, mortgage adheres to the guidelines set by Fannie Mae and Freddie Mac. It may have either a fixed or adjustable rate.
Conventional Loans offer many different options for down payments. The minimum required is 3%. You could also choose to do 5%, 10%, 15%, or 20%, depending on what works best for you and your short and long term benefit.
