Home mortgages are loans that are taken to buy a property, for which the property itself is used as collateral. Owning a home is a very big, and usually a one-time investment for many. With increasing real estate prices and decreasing interest rates on loans, many people are using the home mortgage loans to buy property.
Home mortgage rates are the rates of interest that are to be paid along with the capital for taking the mortgage loan. Home mortgage rates do not remain steady over a long period of time. A lower rate means lower monthly payments, leading to lower costs on the property. Depending on the kind of interest rate, there are two kinds of home mortgage loans: Fixed Rate Mortgages (FRMs) and Adjustable Rate Mortgages (ARMs). FRMs are mortgages for which the rate of interest remains the same for the entire period of the loan. These can be for a period of 10, 15, 20 or even 30 years. Adjustable rate mortgages, on the other hand, have fluctuating rates of interest. This is ideal when there is likelihood of the rates to decrease. ARMs are preferred by people who plan for shorter periods. ARMs are offered at lower rates than FRMs to attract customers, but they also contain a certain level of risk. The fixed rate mortgages are a very predictable, safe option.  
Mortgage rates fluctuate on the basis of an economic index. The mortgage bond market works according to a process called securitization. This securitization enables creation of more loans and greater mobility of funds by keeping the mortgage rates low and allowing more credit for ideal customers.
