How lenders typically size a HELOC
Most lenders cap combined loan-to-value at 80–85%. Multiply your value by that cap, subtract your mortgage balance, and that's a rough credit line ceiling.
Why a CMA helps
Lenders order their own appraisal, but going in with a defensible opinion of value sets expectations and avoids surprises at closing.
When a HELOC makes sense
Common uses: home improvements that protect or grow your value, consolidating high-rate debt, or a flexible reserve. Always review with a licensed lender.
A few honest notes
- This is an estimated opinion of value, not an appraisal.
- A full CMA may require reviewing property condition, updates, location, and recent comparable sales.
- No estimate is guaranteed.
- Refinancing, HELOC, insurance, and tax decisions should be reviewed with the appropriate licensed professional.
