A line of credit extended to a homeowner that uses the borrower's home as collateral. Once a maximum loan balance is established, the homeowner may draw on the line of credit at his or her discretion. Interest is charged on a predetermined variable rate, which is usually based on prevailing prime rates.Once there is a balance owing on the loan, the homeowner can choose the repayment schedule as long as minimum interest payments are made monthly. The term of a HELOC can last anywhere from less than five to more than 20 years, at the end of which all balances must be paid in full. |||Several factors can lead to strong growth rates in this type of borrowing:-Increased retail sales channels, which have brought HELOCs to the masses. Most of these sales channels come from local banking institutions.-Rising home values, which increase the amount of equity available to homeowners -Prevailing low interest rates coupled with moderate inflation-The fact that mortgage interest is often tax-deductible, making it more attractive than alternative borrowing methodsBecause HELOC interest is variable, homeowners must be aware of prevailing interest rates -a spike can cause repayment balances to rise rapidly.
