Start with the real decision, not the search phrase.
Accessing equity can solve a real need while also repricing or extending debt secured by the home. Start with the amount needed and the current mortgage, then compare replacing the first loan with structures that may preserve it.
Use a lender-supported property value and current lien payoff rather than assuming an online estimate equals usable equity.
Compare the rate and term on the entire replacement mortgage, not only the extra cash received.
Model the new required payment and total repayment horizon alongside alternatives that keep the existing first mortgage.
