Can someone explain how this works?
A distant family member did this on the house of one of their kids, and it saved them from losing it in a foreclosure. The other lender was so angry with them for refusing to release their lien; but they couldn't legally force them to do it.
Skirting what's owed, playing games with manufactured leverage, getting repossessed - these are all the factors that cause people with lower credit scores to pay a lot more for their loans.
