If you bought or refinanced your home before 2022, you likely have a mortgage rate below 4%. Cash-out refinancing in 2025 means replacing that rate with a 7%+ rate on your entire balance. A HELOC lets you borrow against equity without touching your existing mortgage — preserving that locked-in low rate.
How a HELOC Works
A HELOC works like a credit card secured by your home equity. You're approved for a credit limit (typically up to 85% combined LTV), and you draw on it as needed during the draw period (usually 10 years), paying interest only on what you borrow. After the draw period, you repay principal and interest over 10–20 years.
HELOC rates are variable — typically Prime Rate + 0.5–2.5%. In 2025, that puts rates around 7.5–9.5%. Your rate moves up and down with the Fed's benchmark rate.
How Cash-Out Refinance Works
A cash-out refinance replaces your entire mortgage with a new, larger loan. The difference between your old balance and new balance goes to you as cash. If you owe $200,000 on a $400,000 home and take a $280,000 cash-out refi, you receive $80,000 minus closing costs and reset the clock on a 30-year mortgage.
Cash-out refis have fixed rates and are often lower than HELOC rates. But closing costs run $3,000–$7,000+, and for anyone with a sub-4% mortgage, replacing the entire balance at 7% is extremely costly.
When Each Makes Sense
- •Choose HELOC if: You have a low existing mortgage rate, need flexible access to funds over time, or want a revolving credit line for projects
- •Choose cash-out refi if: Your current rate is already high (close to market), you need a large lump sum, or you want the simplicity of one payment
- •Neither: If you'd use the money for lifestyle spending, vacations, or non-essential purchases — borrowing against your home for discretionary spending is high-risk
The single most important question: what's your current mortgage rate? If it's below 5%, a HELOC almost always wins in 2025. If it's above 6%, the rate difference is small enough that the simplicity of a cash-out refi might make sense depending on your needs.
