The Mortgage Advisory

Should I use a HELOC to pay for home improvements like a renovation, new roof, or ADU?

The short answer

Often, yes. For homeowners with equity and a low first-mortgage rate, a HELOC is usually one of the lowest-cost ways to pay for a renovation, a new roof, or an ADU, and the interest may be tax-deductible when the money improves your home. Just know the home is valued as it is today, not after the work. The Mortgage Advisory helps homeowners in California, Texas, Florida, and Colorado size the line to the real project budget.

Why is a HELOC a good fit for home projects?

  • Keeps your low first-mortgage rate instead of refinancing it away.
  • Lower rates than credit cards or most personal loans, because your home secures it.
  • Fast: some of the HELOCs we arrange close in days, which helps when a contractor is ready to start.
  • May be tax-deductible when the money improves your home. Check with your tax professional.

What should I watch out for?

  • Your home is valued as it is today. The lender won't count the value the remodel will add, so size the project to today's equity.
  • Budget overruns. Add a 10% to 20% cushion to the contractor's number.
  • Draw timing. Some programs require you to take most of the money at closing. If your project is paid in phases, we'll look for a program that fits.
  • ADUs and big remodels: permits and timelines can stretch. Plan the payment around the longest realistic schedule.

What are the other options?

  • Cash-out refinance: makes sense if your current rate is higher than today's rates.
  • Renovation loans that lend on the after-repair value: helpful when you don't have enough equity today, though they come with more paperwork and inspections.
  • Personal loan: fast, but usually a higher rate and a shorter term.

Example scenario (illustrative)

A couple in Long Beach wants to build a $180,000 ADU for an aging parent. Their home is worth $1.1 million with $420,000 owed on a 2.9% mortgage. At an 80% combined limit, they could borrow up to $460,000, so a $200,000 fixed-rate HELOC (with a cushion) fits comfortably, and their 2.9% first mortgage stays untouched.

Our take

For most homeowners with equity, a HELOC is my first choice for home projects. Get a real contractor bid, add a cushion, and let me show you the fixed-rate payment before you sign anything with your builder.
