Is a HELOC rate fixed?
Many HELOCs use variable rates, although some products may offer fixed-rate conversion features. Terms vary.
Will the lender replace my first mortgage?
A HELOC or fixed second generally sits behind the existing first lien, while a cash-out refinance replaces the first mortgage.
Which option is cheapest?
The answer depends on amount, usage period, rates, fees, existing first-mortgage terms, tax considerations, and repayment behavior.
