HELOC vs. Cash-Out Refi: Financing Your Next Florida Rental

You've got equity in your primary home or a rental. You want to buy another Florida property. A HELOC or a cash-out refinance could get you there—but which one? And does it matter if the equity is in your house or your rental?

Quick answer: A HELOC keeps your existing mortgage intact and gives you a revolving line of credit—pay interest only on what you draw. A cash-out refi replaces your mortgage with a larger one and hands you a lump sum. If your current rate is under 5%, a HELOC usually wins—you keep that rate and avoid refinancing into today's 6.5–7.5% market. If your rate is 7% or higher, a cash-out refi can lock in a fixed rate and simplify to one payment. For investment properties, both are harder to get than for primary residences—stricter LTV, higher credit, more reserves.

HELOC vs. Cash-Out Refi: The Core Difference

Formula: HELOC = second lien + revolving credit. Cash-out refi = new first mortgage + lump sum. HELOC: you keep your current mortgage, add a line of credit secured by the same property. Draw when you need it, pay interest only on the balance. Cash-out refi: you replace the old loan with a new, larger one. The difference goes to you at closing. One payment, fixed rate (usually), no revolving access.

Example: Your Orlando home is worth $400,000. You owe $200,000 at 3.5%. You want $80,000 for a rental down payment. HELOC: You get a $80,000 line at 8.5% variable. You draw $80,000. Your first mortgage stays at 3.5%. You pay interest only on the $80,000 (~$567/month). Cash-out refi: You refinance to $280,000 at 7%. You get $80,000 at closing. Your entire mortgage is now at 7%. Your payment jumps—you've given up the 3.5% rate on $200,000. Over 10 years, the HELOC saves roughly $49,000 compared to refinancing the whole balance.

What's good or bad? If you have a low rate (under 5%), a HELOC preserves it. If you have a high rate (7%+), a cash-out refi can lower your overall cost. The break-even depends on how much you're borrowing and for how long. Run the numbers both ways.

LTV and Equity Requirements

Formula: HELOC on primary: typically 80–85% combined LTV. HELOC on investment property: 65–75% max—fewer lenders offer it. Cash-out refi on primary: 80% LTV conventional. Cash-out refi on rental: 70–75% LTV, sometimes 80% with DSCR loans.

Example: Your Tampa rental is worth $300,000. You owe $180,000 (60% LTV). You want $45,000 for another down payment. Cash-out refi: Refinance to $225,000 (75% LTV). You get $45,000. HELOC on rental: Harder. Most retail banks don't offer investment property HELOCs. If you find one, expect 70–75% max CLTV. $300,000 × 0.75 = $225,000 total debt allowed. You already owe $180,000. Max HELOC: $45,000. You'd need 720+ credit, 6+ months reserves, and full income docs.

What's good or bad? Investment property HELOCs are scarce. If your equity is in your primary home, a HELOC there's easier—75–90% CLTV, more lenders, lower rates. Using primary-home equity to fund a rental down payment is a common strategy. The interest is tax-deductible when the funds are used for the rental (see below).

Interest Rates and Closing Costs

Formula: HELOC: variable, Prime + margin. Late 2025–2026: 8–9.5%. Closing costs: $0–$500, often waived. Cash-out refi: fixed, 6.5–7.5% (30-year). Closing costs: 2–5% of loan amount.

Example: You need $100,000. HELOC: 8.5% variable, $0 closing. Interest-only: $708/month. Cash-out refi: 7% fixed, 3% closing = $3,000. Amortizing payment on $100,000: ~$665/month (but you're also refinancing your existing balance—so the comparison is total payment, not just the new money). On a $100,000 standalone draw, HELOC wins on closing costs. Cash-out refi wins on rate stability—no surprise increases if the Fed hikes.

What's good or bad? HELOC rates move with Prime. If rates drop, your HELOC payment drops. If they rise, it rises. Cash-out refi locks you in for 30 years. In a high-rate environment, locking can feel safer. In a falling-rate environment, a HELOC gives you flexibility to pay down and avoid overpaying. Check for HELOC prepayment penalties—some lenders charge if you pay off within 2–3 years.

Tax Deductibility: It Depends on Use

Formula: Interest is deductible when the borrowed funds are used to buy, build, or bigly improve the property securing the loan—or when used for rental property acquisition or improvements. The $750,000 combined debt limit applies (married filing jointly).

Example: You use a HELOC on your primary home to fund a $60,000 down payment on an Orlando rental. The interest on that $60,000 is deductible as rental expense on Schedule E—because the funds went to the rental. You must document the use. Keep the HELOC draw and the rental purchase in the same timeframe; trace the funds clearly. If you mix HELOC funds (some for a vacation, some for the rental), you allocate interest proportionally. Only the rental portion is deductible.

What's good or bad? Both HELOC and cash-out refi interest follow the same IRS rule: deductibility depends on use, not the loan product. Use for rental = deductible. Use for personal expenses = not deductible. Document everything. If you're doing a 1031 exchange or weighing sell vs. keep, factor in that borrowed funds for a down payment add debt service—run the cash flow with the new payment included.

When a HELOC Makes More Sense

• You have a low existing mortgage rate (under 5%). Refinancing would destroy that rate. A HELOC lets you tap equity without touching the first mortgage.
• You need flexible access. You're not sure exactly how much you'll need, or you'll draw over time (phased renovations, multiple acquisitions). A HELOC acts like a credit line—borrow, repay, borrow again during the draw period.
• You want speed. HELOCs can close in 7–14 days with some lenders. Cash-out refis typically take 30–45 days.
• You want to minimize upfront cost. $0–$500 vs. 2–5% of the loan. On $100,000, that's $2,000–$5,000 saved at closing.
• Your equity is in your primary home. Primary residence HELOCs are widely available. Investment property HELOCs are rare.

When a Cash-Out Refi Makes More Sense

• Your current mortgage rate is 7% or higher. Refinancing into a similar or lower rate doesn't cost you much—and you get a fixed rate for 30 years.
• You need a large lump sum. You're buying a property, doing a major renovation, or consolidating debt. You want the cash at closing, not a line to draw from.
• You want one payment and predictability. Fixed rate, fixed term. No variable-rate surprises.
• You're refinancing an investment property. DSCR cash-out refis qualify on rental income, not W-2. No income docs. 75–80% LTV. 3–6 month seasoning. Good for portfolio investors with 10+ properties or self-employed income.

Investment Property Specifics: HELOC vs. Refi

HELOC on rental: Few lenders offer it. Expect 70–75% max CLTV, 720+ credit, 6–12 months reserves, full documentation. Rates run 0.5–0.75% above primary residence HELOCs. If you can get a HELOC on your primary and use those funds for the rental, that's usually easier.

Cash-out refi on rental: Three paths. Conventional: 70–75% LTV, 6+ month seasoning, full W-2/tax docs. DSCR: 75–80% LTV, no income docs—qualifies on rental income. DSCR of 1.0–1.25 typically required. Non-QM: 70–75% LTV, bank statements or asset depletion. Good for self-employed or complex income.

Alternative: If you're scaling a portfolio, a DSCR cash-out refi can be simpler than a HELOC on the rental—fixed rate, no income verification, one closing. Compare rates and terms.

Common Mistakes With HELOCs and Cash-Out Refis

1. Refinancing a 3% mortgage to get cash. You're trading a 3% rate on $200,000 for a 7% rate on $280,000. The math rarely works. Use a HELOC instead.
2. Ignoring the HELOC repayment phase. During the draw period (5–10 years), you pay interest only. When it converts to repayment (10–20 years), principal kicks in. Your payment can jump. Plan for it.
3. Borrowing without a clear use. HELOC interest is only deductible when funds go to the securing property or a rental. If you use it for a boat, you get no deduction.
4. Skipping the full fee schedule. Cash-out refi: get the total closing cost estimate. HELOC: check for annual fees, early closure penalties, and rate caps.
5. Assuming you can get a HELOC on a rental. Most banks don't offer them. If your equity is in a rental, a cash-out refi (or DSCR refi) is usually the path.

The Bottom Line

HELOC and cash-out refi both tap equity. HELOC keeps your existing mortgage, gives you a line of credit, and costs less upfront. Cash-out refi replaces your mortgage, gives you a lump sum, and locks in a fixed rate. Your current rate is the deciding factor—low rate, use HELOC; high rate, consider refi.

Before you commit, run the numbers. Factor in hidden costs on the new property—and remember that Florida property taxes reassess at purchase price, so budget for the full bill. If you're doing a 1031 exchange, debt on the replacement property affects your exchange math. And if you're weighing sell vs. keep, borrowing against equity is one way to access capital without selling—but it adds debt service. Make sure the new rental's cash flow covers it.
