“You’re already at a 70K loss on the condo. If you can, get out now.”
“If you can get out” seems to be the key question. Otherwise, no way will I just eat $70k in one shot. Even if I sink $1k per mo. for 3 yrs it’ll only be $36k. Consider loss of rent, maintennace, etc..$50k, but I’ll have the very small chance of a turnaround (small chance, I know)
