Frequently asked questions

What's the difference between a HELOC and a second mortgage?+

A HELOC is revolving credit — you can draw, repay, and redraw against your available limit, similar to a credit card secured by your home. A second mortgage is a fixed lump-sum loan with its own amortization schedule.

Why is my available HELOC lower than 65% of my home value?+

Because your combined secured debt (existing mortgage plus HELOC) is also capped at 80% of your home's value. If your mortgage balance is high relative to your home's value, that 80% combined limit — not the 65% HELOC-only limit — usually ends up the binding constraint.

Is HELOC interest tax-deductible?+

It can be, if the borrowed funds are used for investment or business purposes — not for personal use like renovations or debt consolidation. This depends on your specific situation; talk to an accountant before assuming deductibility.
