Here is Chatgpt:Yes, you can generally get a tax deduction for donating real property, like a house, to a 501(c)(3) organization, but there are a few important details to consider:Fair Market Value (FMV): For tax purposes, the deduction is based on the fair market value of the property at the time of donation.

I'd say they are both cash flow market. 

I would skip this and buy a 4 family with below market rents and raise rents and do value ad to get rents up to market!  

Through loopholes there are many home owners that are illegal immigrants, if they get deported , what will happen to their homes?

It's not illegal as far as i'm aware, However it only works because section 8 is so competitive in D.C, I imagine it might be a turn off to potential tenants in less competitive markets

Too many wholesalers are so eager to get a contract that they lock up properties way above market value, hoping to find a buyer who doesn’t know any better.

Do you know the markets you threw out really well? 

It affects the marketability/value of the property. 

But it does give an easy way out for busy out of state heirs who don't want to deal with organizing with other heirs to redeem the property, put it on the market and split the proceeds.

or get good tenant for around 1200$ on vacant unit (i reduced rent from 1350 to 1200 as not much interest in current market) and hold few more years absorbing repair costs and contractor issues, trees issues, retention wall issues, tough neighbor issues, loud music, tobacco etc. smell issues, dogs barking issues.7.
