The formula

How this number is built

available = value × CLTV − mortgage balance · payment shifts from interest-only to full amortisation
Step by step

Doing it by hand

Step 1

Get a realistic home value; lenders order their own appraisal and it may come in lower.

Step 2

Confirm the lender's maximum combined loan-to-value, which varies widely.

Step 3

Model the payment after the draw period ends, not just the interest-only figure.

Step 4

Stress test a rate rise, because most home equity lines carry variable rates.

Questions

What people ask next

HELOC or home equity loan?

A line is revolving and usually variable; a loan is a fixed lump sum at a fixed rate. Use the line for uncertain amounts and the loan for a known cost.

What happens if I cannot repay?

The debt is secured by your home, which means foreclosure is the ultimate remedy. That is why the rate is lower than unsecured credit.
