Results explained
The headline is equity dollars (value minus liens). Borrowing room subtracts existing debt from the CLTV cap — real approvals depend on credit, income, and product.

Second liens and PMI are not broken out unless you fold them into the balance.
How the estimate is built
Equity = home value − mortgage balance. Max debt = value × CLTV%; borrowing room = max(0, max debt − balance).
Example scenario
A $425,000 home with a $280,000 mortgage leaves $145,000 equity (34%). At 80% CLTV, max debt is $340,000 — about $60,000 of additional borrowing room before other limits.
FAQ
Does this include a HELOC I already have?
Add open HELOC balance into the mortgage/lien field if you want net room on top of existing lines.
Is CLTV the same as LTV?
CLTV counts all secured debt on the home; we use one balance field for simplicity.
Will an appraisal match my estimate?
Lenders use their own valuation — treat this as planning math only.
