Homeowners access equity through two main paths: refinancing their existing mortgage or adding a HELOC (Home Equity Line of Credit) as a second lien. Here's when each makes sense.
The core question: do you need to touch your first mortgage?
If your current mortgage rate is below 5.5%: Do not refinance into today's market. A rate-and-term refinance would replace your low rate with a higher one. A HELOC lets you access equity without disturbing your first mortgage.
If your current rate is 6.5%+: A refinance may make sense — either rate-and-term if you want a lower payment, or cash-out if you need equity too.
Rate-and-term refinance — when it makes sense
A rate-and-term refinance replaces your existing mortgage at a new rate and/or term without changing the loan balance (or with minimal cash out for closing costs).
Makes sense when:
- Market rates have dropped 0.5%+ below your current rate
- You want to shorten your term (30-year to 15-year)
- You want to switch from ARM to fixed
- You're removing FHA MIP by refinancing to conventional (once you have 20%+ equity)

HELOC — when it makes sense
A HELOC is a second lien line of credit that gives you revolving access to your home equity without touching your first mortgage.
Makes sense when:
- Your first mortgage rate is below current market rates (most 2020–2022 buyers)
- You need flexible access to funds over time (renovation phases, tuition)
- Closing costs matter — HELOC closing costs are typically much lower than a full refinance
- You want to preserve optionality — pay back what you borrow, redraw as needed
HELOC trade-offs:
- Variable rate — can increase if the Fed raises rates
- 10-year draw period followed by repayment period — payment changes at transition
- Second lien — if you default, second lien gets paid after first
FAQs
Should I refinance if my current rate is 3.5%?
Almost never. A rate-and-term refinance would replace your low rate with today's higher market rate on your full balance. If you need equity access, use a HELOC. If you don't, keep your existing mortgage.
How is a rate-and-term refinance different from a cash-out refinance?
A rate-and-term refi keeps your loan balance the same (except for financed closing costs) and changes only your rate and/or term. A cash-out refi increases your loan balance to give you cash at closing. Both replace your existing first mortgage.
Can I have a HELOC and refinance later?
Yes. A HELOC is a second lien — you can still refinance your first mortgage later. However, you'll need to either pay off the HELOC at closing or get the HELOC lender to subordinate (agree to remain in second position behind the new first mortgage). Subordination is common but not automatic.
How long does a HELOC take to close vs. a refinance?
HELOCs typically close in 2–4 weeks. Refinances typically take 30–45 days. HELOCs have simpler underwriting and don't require a full first-mortgage payoff.
