For example, right now I am renovating a 20-unit apartment complex...we are pulling out a lot of old appliances and I want to donate for the tax write offs.

I'm talking: sponsorships, donations, community outreach, sitting on the board of directors for companies and organizations.

I think you can become a member if you donate to one of the associated military focused non-profits.

My daughter was evacuated for days, and set her real estate office up to receive donations and distribute to those that lost homes, only to have her son end up losing his.

I think you just have to find the right people to donate (or reasonably paid) their time to helping better fellow humans.

I could neither act as PM or donate time to act as PM. 

I'm sure you could find a donation center that would want it.

My tax advisor stated Box 1 "Rents" and the church tax advisor states Box 7 "Non-Employee Compensation" since it's not actual rent for the church but considered a donation to them.

Realize, too, that fix and flippers tend to have cheap sources for this sort of thing and would not pay anywhere near what a homeowner would pay a kitchen fixing company.Your best bet may be to donate the cabinets and appliances to Habitat for Humanity.

Person 1 could form a 501c3 charity to do this out of but would need to raise money from donations to make it happen.
