HELOCs have two phases. During the draw period, you use the line of credit all you want, and your minimum payment may cover just the interest due. But eventually (usually after 10 years), the HELOC draw period ends, and your loan enters the repayment phase. At this point, you can no longer draw funds and the loan becomes fully amortized for its remaining years.
*Credit scores are based on information collected by credit bureaus and information reported each month by your creditors about the balances you owe and the timing of your payments. A credit score is a compilation of all this information converted into a number that helps a lender to determine the likelihood that you will repay the loan on schedule. The credit score is calculated by the credit bureau, not by the lender. Credit scores are calculated by comparing your credit history with millions of other consumers.
