For years, when someone wanted to purchase or refinance a home, the choices were simple. The buyer chose either a 15-year fixed-rate mortgage or a 30 year fixed-rate mortgage. That was it. Of course, those were also the days of twenty percent down payments, which seriously hindered the ability of many Americans to obtain the loan necessary to buy their own home. In recent years, more flexible loan types have become available and down payment requirements have been relaxed. There are now far more choices of loan types available for the borrower than ever before. That can be a mixed blessing, however, as prospective borrowers now have to do a tremendous amount of homework in order to determine which type of loan might be the best choice. The selection of loan types that are currently available can be quite bewildering, and the wrong choice could cost the prospective borrower thousands of dollars over the term of the loan.
