Frequently Asked Questions
How is a HELOC different from a home equity loan?
A HELOC is a revolving credit line (like a credit card) secured by your home, with variable rates and a draw period. A home equity loan provides a lump sum with fixed monthly payments and a fixed rate.
How much HELOC can I get?
Most lenders allow a combined loan-to-value (CLTV) ratio of 80-90%. If your home is worth $500,000 and you owe $300,000, at 80% CLTV you can borrow up to $100,000 via HELOC ($500K × 80% − $300K).
What are the draw and repayment periods?
A typical HELOC has a 5-10 year draw period where you can borrow and make interest-only payments, followed by a 10-20 year repayment period where you pay principal plus interest on the outstanding balance.
