If the house wasn't a part of the equation and the family came to you and said out mom is in a tough situation, we really need $35k would you donate that money?

@Pete Abilla, the easiest conclusion to draw is that the glut of housing inventory in the donating (departing) metros will lead to longer times on market and lower prices (buyer's market) while the receiving (arriving) metros will have shorter times on market and higher prices (seller's market).

If I could donate the property and get the ~$4000 tax write-off without paying the taxes that would be the best

The land was donated to the church in the 60's and they built the house.

I'd keep the remaining $100K for reserves/emergency fund, FUN MONEY, donations, and put the rest in a CD.  

Curiously the blood center was crowded with people donating. 

If not, no problem, if you tell them you donate to the Red Cross you qualify as well.  

I encourage everyone looking for a way to help out to find your local food pantry and make a donation!

Even at the LOWEST of end, that would be $2,500,000 that an owner would have to decide to donate to his tenants to cover their rent personally. 

Go through closets, wardrobes, toys, garages, etc. and make piles of trash, donate, keep.
