How a HELOC works
The lender values the home, sets a maximum combined loan-to-value, subtracts your first mortgage and opens a line for the difference. During the draw period, commonly 10 years, you borrow and repay as you like, and minimum payments are often interest-only. After that the line closes to new draws and the balance amortizes, commonly over 20 years. The rate is usually variable, tied to an index such as the Prime Rate plus a margin, so the payment moves with the market.
Round numbers, chosen to show the math rather than to reflect any particular lender or file. Your figures, program and pricing will differ.
| Home value | $700,000 |
|---|---|
| Lender combined cap (85% in this example) | $595,000 |
| Existing first mortgage | $320,000 |
| Available HELOC line | $275,000 |
| Drawn in year one for a kitchen | $50,000 |
Interest accrues on the $50,000 drawn, not the $275,000 line. The first mortgage at $320,000 stays exactly as it was.
For illustration only. Not a commitment to lend, a rate lock or an offer of credit. Terms vary by lender, by property and by file.
