Cash-Out Refinance vs HELOC: Which Should You Use to Fund Your Next Deal?

FinancingBy the Home Nexio Editorial Team2 min read

Quick Answer

A cash-out refinance replaces your entire mortgage with a larger one at a new rate, giving you a lump sum. A HELOC is a separate revolving line of credit secured by your equity, on top of your existing mortgage. HELOCs are cheaper to open and more flexible; cash-out refis make sense when today's rates beat your current one.

You've built up equity and you want to put it to work on your next deal. The two obvious tools — cash-out refinance and HELOC — both pull cash out of a property you already own, but they work completely differently, and picking the wrong one can cost you thousands over the life of the loan.

How a Cash-Out Refinance Works

A cash-out refinance pays off your existing mortgage entirely and replaces it with a new, larger loan. The difference between the new loan amount and what you owed comes to you in cash at closing. Your old mortgage is gone — you now have one loan, at one rate, for one term.

Example

Home value: $400,000
Current mortgage balance: $200,000
New loan at 80% LTV: $320,000
Cash to you at closing: $120,000 (minus closing costs)

Because it's a full refinance, you'll go through the entire mortgage process again — appraisal, underwriting, closing costs typically running 2-5% of the loan amount — and your rate resets to whatever today's market offers, for better or worse.

How a HELOC Works

A home equity line of credit is a second loan, separate from your first mortgage, secured by the same property. It functions like a credit card with your home as collateral: you're approved for a credit limit, you draw against it as needed, and you only pay interest on what you've actually borrowed — not the full limit.

Most HELOCs have two phases: a draw period (commonly 10 years) where you can borrow and repay repeatedly, followed by a repayment period where the balance amortizes and you can no longer draw new funds. Rates are usually variable, tied to the prime rate, which means your payment can move with the market.

When a Cash-Out Refinance Wins

Today's mortgage rates are at or below your current rate
You want one predictable, fixed payment instead of a variable one
You need a large lump sum for a single purpose, like a down payment on another property

When a HELOC Wins

Your current mortgage rate is well below today's rates — refinancing would mean giving that up on your entire balance, not just the cash you're pulling out
You want flexibility to draw funds over time (renovation draws, multiple smaller deals) rather than one lump sum
You want lower upfront closing costs

For investors specifically, the HELOC's flexibility often wins when you're not sure exactly how much capital you'll need or when — it sits there as available credit until you actually need it, without forcing you to borrow (and pay interest on) money before you have a deal to deploy it on.

Frequently Asked Questions

Which is cheaper, a cash-out refinance or a HELOC?

Closing costs are usually lower on a HELOC (often a few hundred dollars vs. 2-5% of the loan amount on a refinance). But if your current mortgage rate is well above today's rates, a cash-out refinance can still save money overall by replacing a high-rate loan with a lower one.

Does a HELOC affect my existing mortgage rate?

No. Your first mortgage stays exactly as it is — same rate, same term, same payment. The HELOC is a completely separate second lien, which is exactly why it makes sense when your existing rate is lower than current market rates.

Can I use a HELOC like a credit card?

During the draw period (typically 10 years), yes — you can borrow, repay, and re-borrow up to your credit limit, paying interest only on what you've drawn. After the draw period ends, most HELOCs enter a repayment period where you can no longer draw and must pay down the balance, often over 10-20 years.

Is interest on a cash-out refinance or HELOC tax-deductible?

Interest is generally deductible only when the funds are used to buy, build, or substantially improve the property securing the loan — not for unrelated expenses like debt consolidation or a vacation. Talk to a tax professional about your specific situation before assuming deductibility.

How much equity can I access with each option?

Both are typically capped around 80-85% combined loan-to-value, though some lenders go higher for strong borrowers. A $400,000 home with a $200,000 mortgage balance and an 80% cap gives you roughly $120,000 in accessible equity through either route.
