Facts of the story, minus any emotional appeal:
- She bought a condo for market value of ~$240,000
- She paid cash for most of it
- Several years later, the owners of 80% of the condos decide that they want to convert to rental apartments
- Law says that 80% owners may do this, provided that they buy all of the properties at current value
- The 80% owners offer to pay her the assessed value of the condo, which is ~$47,000
Yeah, I get it - it sucks. But, that's the chance you take when you
A) pay cash for something (at least she's "even"; if she'd taken out a massive load, she might even be in debt)
B) buy a condo
C) are subject to market forces.
