What does equity have to do with foreclosure?

Equity is what a homeowner has to lose in a foreclosure, and homeowners with meaningful equity almost always come out ahead selling the home themselves rather than letting it go to foreclosure, which typically wipes out that equity entirely. A traditional sale, even a fast one, generally preserves far more value than a forced foreclosure sale does. That's why talking to an agent early, before missing payments, matters more than waiting to see what happens.
