Frequently Asked Questions

Most lenders allow a combined loan-to-value (CLTV) ratio of 80-85%. So if your home is worth $400,000 and you owe $250,000, your available equity is $400,000 × 85% - $250,000 = $90,000.

A HELOC has two phases: a draw period (typically 10 years) where you can borrow and make interest-only payments, and a repayment period (typically 20 years) where you pay principal plus interest on the outstanding balance.

HELOC rates are typically variable, based on the prime rate plus a margin. As of 2024, rates range from 8-10% depending on credit score and LTV ratio. Some lenders offer fixed-rate conversion options.

How a HELOC Works

Draw Period (10 years)

During the draw period, you can borrow up to your credit limit and only pay interest on the amount you have drawn. Your minimum payment is interest-only, meaning your balance does not decrease unless you make extra principal payments.

Repayment Period (20 years)

After the draw period ends, you can no longer borrow. Your payments now include both principal and interest, and the payment amount will be higher than during the draw period. The balance is fully amortized over the repayment period.

LTV (Loan-to-Value)

Most lenders allow a maximum combined LTV of 80-90%. With a 85% max LTV, your combined mortgage + HELOC cannot exceed $340,000 on a home valued at $400,000.
