HELOC vs Cash-Out Refinance: which one actually makes more sense?

This educational scenario and its sample explanations are not posts from real users.

I have about $120k in equity and I want to do some renovations ($40k) and maybe pay off a car loan ($18k). My current mortgage rate is 3.75% from 2021. I really don't want to lose that rate. Should I look at a HELOC or is there a better option?

Quick Summary

  1. A home equity loan or HELOC is separate from the existing first mortgage.
  2. A cash-out refinance replaces the first mortgage, including its rate and term.
  3. Compare fees, variable-rate terms and total borrowing costs over the same timeline.

With a 3.75% rate you definitely don't want to cash-out refi right now — you'd be giving up a great rate to borrow at today's rates on your whole balance. HELOC is the obvious answer here. The rate will be higher than your first mortgage but much lower than you'd get refinancing the whole thing. Shop around because HELOC rates vary a lot by lender.

Also look at a home equity loan (second mortgage) if you want a fixed rate. HELOCs are typically variable which is fine if rates drop, but a fixed home equity loan gives you predictability. For $58k total you might have both options available depending on your combined LTV.

Protecting that 3.75% first is the right call. For your situation — HELOC or home equity loan — both keep your first mortgage untouched. A few things to check: your combined LTV (first + new HELOC) needs to be within lender guidelines, usually 80–90% max. Also factor in the HELOC draw period (typically 10 years) vs the home equity loan which amortizes from day one. If you want fixed payments, go home equity loan. If you want flexibility and think you might need more later, go HELOC. Either way, get a few quotes — fees and rates vary significantly.

One thing nobody mentioned — using equity for a car loan payoff is usually fine if the interest savings pencil out, but make sure you're not converting unsecured debt to secured debt without thinking through the risk. If you ever can't pay the HELOC, your house is the collateral. Just worth being aware of.
