No offense, should OP state his/her relationship with the Wang's before people can decide if they want to donate?
And, I would say that morgage is non-recourse loan so the family should not be liable for the debt other than the houses. I think the OP should also get the fact straight to be convincing,
You can not ask for donation while living in huge house on acrage with 100+ rental properties. it's not the right thing to do!!! Shame on you who initiate the donation!
#18's statement trigered my curiosity. I did go to Gwinnett county website and searched Mr. Wang's name. He or some body with idential name has multiple properties in the county. However, unlike what is posted by the OP, most of these were purchased during 2011-2012 time frame. I did not search for other counties so I cannot say that Mr. owns 100+ units though. But I do have suspition about the OP's "FACTS" or motivation.
