Home equity line of credit
Keep your low first mortgage and borrow only what you use
A revolving line of credit secured by your home, ideal for phased renovations and tuition paid over time.

Home equity line of credit: how it works
A HELOC works like a credit card secured by your home. You are approved for a limit, draw what you need during a 10-year draw period, and pay interest only on the balance you use. After the draw period, the balance converts to a repayment schedule.
The biggest advantage for many Boston homeowners is that a HELOC sits behind your existing mortgage. If you locked a 3% rate in 2021, you keep it, and only the new borrowing carries today's rate.
Rates are variable and tied to the prime rate, so we also offer an option to fix the rate on portions of your balance, for example once a kitchen project is complete and the cost is known.
