@Alfredo Morales may I have your address in a PM?

., It is not my desire to discuss the moral or ethical facets of the fair housing laws.

Morally, it sounds like you have a case but perhaps not legally?

Business decisions are measure in the bottom line, not public records, small claims, or achieving moral victories. 

Without moral or personal judgement.

My wife is a cosmetologist(hair/skin/nails), and I feel like refusing to rent to disabled people based solely on them being disabled is morally repugnant, especially given how many of them are veterans.

Moral of my story is I would rather give up some potential gains to work less.  

2) If it is legal, is there some moral line I'm crossing??  

It's not such a big deal to rent to lower income people, just make sure you don't rent to lower class people.Lower income = not having a lot of moneyLower class = liars, drug users/dealers, questionable morals, lack of respectThere are lower income people that have a high amount of class just as there can be more wealthy people that are lower class.Lower income and lower class people can come in any color. 

This debate is no longer about facts.We can clearly see we have one group, mainly consisting of liberals who believe you should follow the letter of the law and abide by what the state dictates is fair and equitable as government should be unquestioned legal and moral arbiter of what is best for society.And we have another group mainly consisting of conservatives/libertarians who believe they should be free to make their own decisions on what they want to do with their own properties even if the government wants otherwise for a greater "social good."
