Not everyone has the time available to donate.

Show them your value, and donate it, if they find usefulness in it you'll be on your way.

Her husband died this year (googling obit - donations in lieu of flowers for a young guy). 

There was money donated from lot owners in a fund and they chose to pay off two lot owners debt in order to keep them out of foreclosure (total $4000).

@Parmer Cherry, Yes you can donate items to qualified charity and possibly get a deduction. 

My company could donate the rental if people are still interested.

also you could donate the homes to a local charity who then make sure the tenants still meet requirements and then you fill it in and get a tax write off. 

PM me if you have any other questions or want to know ways to donate. 

You definitely don't want to donate your sweat equity to the owner or hard money lenders, so you may need to find a partner to carry the financing.

To back up that belief, my wife and I dedicate a minimum of 10% of our income to giving each month, and we also make additional one-off donations as well to charities that positively impact our local community.
