If you want to be charitable donate money to a local organisation. 

I'm being relocated out of state and I was going to rent out my primary, but found out my housing allowance will be voided if I do, so essentially I have to keep it empty if I want to get it...and I definitely want to get it as it will easily pay for the place and my new place.But here's my situation, I'd like to donate the use of the property to my church to use as a mission house.

Call the veterans administration and ask about charity donations to wounded veterans.You can also call Habitat For Humanity for the same information.

They do national eviction searches as part of their rental background check, and they do a criminal and credit check, too.

I don't think it is wrong to not "donate that $700 for the betterment of society" on a tenant that is going to end up buying and be out of the rent game in 3 years anyway.

I'm sure you can save some money by donating your own labor so that might get your foot in the door.

Or did we just donate the money to POL..?

It's free on 9/9, but $10 in the future (donated to charity). 

I am interested in this as well.As far as helping Houston out, here is a link to a donation website organized by JJ Watt.Youcaring.com Link

Most of the country has been donating money and the federal government will write a blank check.
