HELOC vs Cash-Out Refinance: Different Friction, Different Math

Two structures

A HELOC typically sits behind (or sometimes alongside) your first mortgage and lets you draw as needed. A cash-out refinance replaces the first lien with a larger loan.

Closing cost profiles differ: cash-out often looks like a full refinance; HELOCs may emphasize annual fees, variable indexes, and draw rules.

Price the interest and the optionality

If you need a lump sum once, refinance total-cost math may dominate. If you need flexible draws, HELOC interest-on-drawn models matter more.
