Research by Harvard has shown money doesn't buy happiness, owning a business doesn't, religion doesn't ( has shown a sense of belonging ).

I am not allotting possible time away from family, friends, exercise, religion, looking for more of my own investments, etc. without a commitment in writing.  

Folks in religions usually have a moral code and or can help cover for fellow members when things get tight.

People may be discriminated against on the basis of race, gender, age, religion, or sexual orientation - these are protected categories. 

I'm Muslim; my religion prohibits dealing with interest; either directly or indirectly.

"We were all human until race disconnected us, religion separated us, politics divided us and wealth classified us."

I've never heard of "criminals" being a protected class in rental applicatians.Race, religion, disability... yes.

It's hard enough for a small church to finance much less a conversion, unless it's really a big project.There are some religions that believe that no one should ever enter another church or grounds where other religions were practiced, that's a social stigma that can't be overcome.

done hundreds of deals and hundreds of tenants, only been "attempted" to sue twice and I have successfully sued others twice.. its not common but do expect it, have all of your policies laid out clearly and signed by the responsible parties, follow your rules and policies like religion.
