You've built equity. Now what? Most homeowners don't realize there are three distinct ways to access it — each with very different costs, tax implications, and long-term outcomes. Here's the exact comparison.
These aren't interchangeable. They solve different problems. Choosing wrong costs tens of thousands.
| Factor | Sell | Cash-Out Refi | HELOC |
|---|---|---|---|
| You keep your home? | No | Yes | Yes |
| You keep your existing rate? | N/A — no mortgage | No — new rate applies | Yes, 100% |
| How much can you access? | 100% equity (minus fees) | Up to 80% LTV minus existing balance | Up to 85–90% CLTV (combined) |
| Interest rate | N/A | Current market rate (6.375–6.75%) | Variable, typically 7–9% |
| Closing costs | 6% agent + closing | 2–5% of new loan amount | $0–$500 flat (many lenders) |
| Tax deductible? | May have capital gains | Interest may be deductible (consult CPA) | Interest may be deductible (consult CPA) |
| How you access funds | Lump sum at closing | Lump sum at refi closing | Draw as needed, variable amounts |
| Best for | Relocation, downsizing | One major expense, lower existing rate | Ongoing projects, ADU, investment |
| Risk if home values drop | You already sold | Underwater risk on new loan | HELOC may be called/frozen |
You're leaving Temecula or Murrieta for another state. You have $350K in equity. Sell. A HELOC or refi makes no sense if you're leaving — you need the full equity access and you're done managing the property. Consult a CPA on CA capital gains before you close.
You're already at 6.5%, the market has come down a bit, and you need a lump sum for a major renovation or medical expense. A cash-out refi at 6.375% replaces your existing 6.5% — you get the cash AND a slightly lower rate. Run the math on closing costs vs. monthly savings.
This is the most common right move in 2026. You locked 3.25% in 2021 — that's a financial asset worth protecting. A HELOC keeps your first mortgage intact while giving you $150K–$300K to build your ADU. The ADU rental income pays the HELOC payment. You keep the 3.25% rate AND add equity. This is how wealth is built.
You've got equity in your primary, a solid income, and you want to expand into investment property. A HELOC is the fastest, cheapest way to access down payment funds without selling your primary or refinancing your low rate. Many investors cycle HELOC → rental purchase → rental cash flow → pay down HELOC.
If the kids are gone and you're in a 4-bedroom with 2 baths you don't need — sell. But if you want to buy the next home first before selling, a bridge loan keeps you from losing the home you want while you wait for your current home to close. Nick coordinates both transactions simultaneously.
HELOC rates are variable and tied to the prime rate. As of May 2026, most lenders are offering 7.25–8.75% APR for owner-occupied HELOCs with strong credit. Some credit unions offer lower rates for existing members. The rate is typically lower than personal loans or credit cards, and the interest may be tax-deductible (consult your CPA on the specific use of funds).
Yes — in fact, most HELOCs are written as second position behind an existing first mortgage. Your combined loan-to-value (CLTV) is what matters. If you have a $400K home with a $240K first mortgage, you might be able to access up to 85% CLTV = $340K total, meaning up to $100K on the HELOC. Some lenders go to 90% CLTV.
HELOC rates are variable — if the prime rate falls, your HELOC rate falls too (which is good). The risk is the opposite: if rates rise significantly, your HELOC payment could increase. Most HELOCs have a floor rate, but you should model your payment at 10% HELOC rate before you open one to make sure you can still afford it.
For ADU construction specifically: HELOC is almost always better if you have a sub-5% first mortgage rate. Here's why: you draw the HELOC as construction progresses (typically in draws), so you only pay interest on what you've drawn. With a cash-out refi, you're borrowing the full amount day one and paying interest on all of it from day one. For a $200K ADU build over 12 months, the interest difference can be $5,000–$10,000.
Most HELOC agreements have a clause that if your home's LTV exceeds a certain threshold (often 80–85%), the lender can freeze or reduce your line of credit. This happened widely in 2008. In 2026, CA home values are relatively stable in major markets. The mitigation: don't borrow the maximum. Leave a buffer of 10–15% equity in your home after the HELOC.
