HELOC and home equity loans
Borrow against your equity without touching your first mortgage, which matters enormously if yours happens to be from 2020 or 2021.

The one thing that decides this
If you have a mortgage sitting at 3% or 4%, a cash-out refinance doesn't just borrow the money you need, it reprices your entire existing balance at today's rate. The effective cost of the cash you're taking out is frequently double what the quoted rate makes it look like.
A second mortgage leaves that first loan alone. The rate on it is higher, but it only applies to the money you're actually borrowing. In the current environment that usually wins by a wide margin.
Run the comparison here, because on typical numbers the two options come out several hundred dollars a month apart.
HELOC or home equity loan?
| HELOC | Home equity loan | |
|---|---|---|
| Structure | Revolving line, draw as you need it | Lump sum at closing |
| Rate | Variable | Fixed |
| Payment | Interest-only during the draw period, then amortizing | Fixed from day one |
| Best for | Uncertain or staged costs, like renovations, an ADU build, or a reserve you may never touch | A known amount, like debt consolidation or one single project |
| Costs | Often minimal or none | Usually modest |
For an ADU or a renovation where the final number is still unknown, the HELOC's flexibility is usually worth more to you than the home equity loan's rate certainty is. For consolidating a fixed pile of debt, it works the other way around.
How much you can borrow
Most lenders go to 80% combined loan-to-value, and some will go to 85% or 90% at higher pricing. Combined means your first mortgage plus the new second, divided by the home's value. Past 80% both the pricing and the lender availability get noticeably worse.
Timing matters more than people expect
A HELOC costs little or nothing to have open and sitting unused. Lenders will not open one on a home that's listed for sale, and getting one approved takes weeks. So if there's any chance at all that you'll want access to your equity, whether for a bridge to the next house, for a project, or just as a buffer, open it while nothing is happening.
People call me needing one urgently far more often than they call me while they still have time.
Common questions
Is the interest deductible?
Generally only when the funds are used to buy, build or substantially improve the home securing the loan, and only if you itemize. Ask your CPA, not your lender.
What happens when the draw period ends?
The line converts to an amortizing repayment period and your payment jumps, often substantially. Know that date going in, because it surprises people ten years later.
Does a HELOC hurt my credit?
It's a credit pull and a new account, and carrying a large balance can affect your utilization. Neither one is usually significant. But if you're about to buy another property, tell me before you open anything.
Is this the right one for you?
Tell me the situation in plain language and I'll tell you which program actually fits, including the times when the answer turns out to be a different one than the page you're reading.
