Refinance vs. HELOC: Which One Fits Your Situation?

Both let you use your home’s value — but they work in opposite ways. A refinance replaces your entire mortgage; a HELOC adds a separate line on top of it. Which one wins comes down to one thing: the rate you already have.

The deciding question

If your current mortgage rate is well below today’s, a refinance forces you to give up that low rate on your whole balance — an expensive trade. A HELOC borrows only the amount you need, at its own rate, and leaves your first mortgage exactly as it is.

When a refinance still wins

• Your current rate is at or abovetoday’s — there’s no low rate to protect.
• You want a fixed payment, not a HELOC’s variable rate.
• You’re consolidating into one loan and the blended cost beats keeping two.

When a HELOC wins

• You hold a low first-mortgage rate worth keeping (most owners today).
• You need flexible access rather than a single lump sum.
• The project or need is smaller than your full balance.
