There are a variety of mortgages available today and it's important to first understand what type of mortgages the lender offers. The most popular mortgage is the fixed-rate mortgage. You can get a 10, 15, 20, 30, 40, and even 50-year fixed-rate mortgage. FHA loans, insured through the government, are also very popular. Down payments required for FHA loans are low and the FICO requirements are also much lower than required for traditional mortgages. Interest-only loans are yet another option, allowing you the option of interest-only payments and usually requiring a balloon payment at the end of the loan period.
