How it works

Limit = home value x maximum combined LTV minus your mortgage. Interest only payment = amount x rate / 12.

Worked example

A 500,000 home with a 300,000 mortgage and 85 percent LTV allows up to 125,000. Using 50,000 at 8.5 percent costs about 354 a month in interest.

Good to know

HELOC rates are usually variable and tied to the prime rate.
