How it works
You are approved for a credit limit and draw only what you need, paying interest on the outstanding balance rather than the full line. A draw period of five to ten years is typical, followed by a repayment period. Rates are usually variable and tied to prime. It sits in LIENPOS behind your first mortgage.
A homeowner owes $300,000 on a low-rate first mortgage and needs $75,000 for improvements. A HELOC can access equity without replacing the entire first mortgage, although the HELOC rate is commonly variable.
Who it can work well for
Owners with a low-rate first mortgage worth protecting who need flexible access to equity — staged renovations, a business runway, or a standby reserve they may never touch.
What lenders actually look at
The lender evaluates combined loan-to-value, credit, income/DTI, property, lien position and available equity. The line has a maximum limit, but interest is generally charged only on the amount actually borrowed.
Illustrative lender guidelines
These are educational examples, not universal approval rules. Exact requirements and maximum leverage vary by lender and complete scenario.
| Scenario | Credit / qualifier | Illustrative leverage |
|---|---|---|
| Primary, full doc | 740+ | 90% CLTV |
| Primary, full doc | 700-739 | 85% CLTV |
| Primary, full doc | 660-699 | 80% CLTV |
| Primary, no income | 700+ | 60% CLTV |
| Investment property | 700+ | 70% CLTV |
| Draw period | — | 5-10 years |
What to watch for
Variable rates mean your payment can move. When the draw period ends the payment jumps as it converts to principal and interest — know that date before you sign.
Common misconception: opening a $100,000 HELOC means paying interest on $100,000 immediately. Normally interest accrues on the outstanding balance drawn, subject to the line terms.
When this may not be the best choice
It may not fit someone who needs a fixed payment, dislikes variable-rate risk, needs more leverage than a second lien permits, or would benefit from replacing the first mortgage anyway.
