@flocy I'd agree except that a 2% mortgage rate is insanely good and she's not getting anything like that right now. As I'm sure you know, your house is one of the few assets not counted for social services. If she can keep that asset it would be a good idea.
@mimi24 I'm not saying you should do this, but if my friend had a destination wedding and then said, "Hahaha, I don't have money either" I would tell them they were either lying or stupid.
I'm sorry but your friends sound like assholes.
