The 30-second answer
Both pull equity out of a rental, but the mechanics are opposite. A HELOC is a second lien layered on top of your existing mortgage — your first loan is untouched, and you only pay interest on what you draw. A cash-out refinance replaces your first mortgage with a new, larger one and hands you the difference. In 2026's rate environment, the deciding factor is usually your current first-mortgage rate: if it's low, protect it with a HELOC; if it's high or you want a single fixed payment on a big lump sum, a cash-out refinance can win.
The core difference: what happens to your first mortgage
This is the whole decision in one sentence. A HELOC preserves your existing mortgage; a cash-out refinance replaces it. If you locked a 4% loan on a rental years ago, a cash-out refinance would wipe out that 4% across the entire balance just to access a slice of equity — an expensive way to borrow. A HELOC lets you keep the 4% first mortgage and pay a higher rate only on the smaller amount you actually draw.
Side by side
| Feature | HELOC (2nd lien) | Cash-out refinance |
|---|---|---|
| First mortgage | Untouched — keeps its rate | Paid off and replaced |
| Rate type | Variable (prime + margin) | Usually fixed |
| Interest charged on | Only what you draw | The entire new balance |
| Access | Revolving — draw, repay, re-draw | One lump sum at closing |
| Closing costs | Low (sometimes near $0) | Higher (full mortgage costs) |
| Best when | Existing rate is low; need flexibility | Existing rate is high; want fixed lump sum |
When the HELOC wins
You have a low fixed rate on the rental's first mortgage. You want flexible access rather than a lump sum — funding rehabs or the next down payment as needs arise. You value low closing costs and the ability to repay and re-draw. For most investors sitting on cheap first mortgages, this is the default.
When the cash-out refinance wins
Your existing first-mortgage rate is already high, so replacing it costs you little (or a refinance would actually lower it). You're pulling a large, one-time amount and want the certainty of a fixed rate and payment on all of it. Or you want to consolidate a first mortgage plus an existing second into one loan. In those cases the refinance's fixed structure and single payment are worth the closing costs.
A quick cost lens
Say a rental is worth $400,000 with a $200,000 first mortgage at 4%, and you want $60,000. A cash-out refinance replaces the $200,000 at today's higher investor rate and adds the $60,000 — you now pay the higher rate on $260,000. A HELOC leaves the $200,000 at 4% alone and charges a higher variable rate only on the $60,000 you draw. Unless refinancing also improves your first-mortgage rate, the HELOC is dramatically cheaper here. Flip the example to a high existing rate and the math flips too.
The honest take
The industry defaults investors to cash-out refinances because they're simpler to originate — but in a world where a lot of investors are sitting on low pandemic-era first mortgages, refinancing to access equity is often the expensive choice. Start by asking what rate you'd give up. If it's a good one, protect it with a HELOC. If it's not, the refinance is back on the table.

FAQ
Is a HELOC or cash-out refinance better for a rental property?
It usually comes down to your existing mortgage rate. If your rental has a low fixed first mortgage, a HELOC is often better because it leaves that rate alone and only charges you on what you draw. If your first mortgage rate is high (or you want one fixed payment and are pulling a large lump sum), a cash-out refinance can make sense despite resetting the loan.
Can you do a cash-out refinance on an investment property?
Yes. Cash-out refinances on investment properties are common but capped lower than on a primary residence — typically around 70–75% LTV — and priced higher. You replace your existing mortgage with a new, larger one and take the difference in cash.
What's the LTV limit pulling equity from a rental?
For both HELOCs and cash-out refinances on investment properties, expect roughly 70–75% combined loan-to-value, versus 80–85% on a primary residence. The exact cap depends on the lender, your credit, and the number of properties you own.
Does a HELOC on a rental affect my existing mortgage?
No — that's a key advantage. A HELOC is a separate second lien, so your first mortgage keeps its existing rate, term, and payment. A cash-out refinance, by contrast, pays off and replaces that first mortgage entirely, so you lose whatever rate you had on it.
