Fixed Rate Mortgages
A fixed-rate mortgage (FRM), often referred to as a "plain vanilla" mortgage loan, is an fully amortizing mortgage loan where the interest rate on the note remains the same through the term of the loan, as opposed to loans where the interest rate may adjust or "float". As a result, payment amounts and the duration of the loan are fixed.
Adjustable Rate Mortgages
A variable-rate mortgage, adjustable-rate mortgage (ARM), or tracker mortgage is a mortgage loan with the interest rate on the noteperiodically adjusted based on an index which reflects the cost to the lender of borrowing on the credit markets. The loan may be offered at the lender's standard variable rate/base rate. There may be a direct and legally defined link to the underlying index, but where the lender offers no specific link to the underlying market of index they can choose to increase or decrease at their discretion.
A hybrid ARM features an interest rate that is fixed for an initial period of time, then floats thereafter. The "hybrid" refers to the ARM's blend of fixed-rate and adjustable-rate characteristics. Hybrid ARMs are referred to by their initial fixed-rate and adjustable-rate periods, for example, 3/1, is for an ARM with a 3-year fixed interest-rate period and subsequent 1-year interest-rate adjustment
An FHA insured loan is a Federal Housing Administration mortgage insurance backed mortgage loan which is provided by a FHA-approved lender. FHA insured loans are a type of federal assistance and have historically allowed lower income Americans to borrow money for the purchase of a home that they would not otherwise be able to afford. To obtain mortgage insurance from the Federal Housing Administration, amortgage insurance premium (MIP) equal to a percentage of the loan amount at closing is required, and is normally financed by the lender and paid to FHA on the borrower's behalf. Depending on the loan-to-value ratio, there may be a monthly premium as well.
Interest Only Mortgages
An interest-only loan is a loan in which, for a set term, the borrower pays only the interest on the principal balance, with the principal balance unchanged. At the end of the interest-only term the borrower may enter an interest-only mortgage, pay the principal, or (with some lenders) convert the loan to a principal and interest payment (or amortized) loan at his/her option.
