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.

It also helps when promoting yourself as someone who knows what he's doing, and will probably boost your confidence, too.In other words, it wouldn't have been a waste of time and money, in my opinion.  

I think it might give the property he little boost it needs to rent quickly.

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

You need to fire them all and start fresh.Time to hire your own lawyer.I'm just here to boost my post count since Sue already put a slam dunk on this thread.

When you sign that lease the company receives your tax credit and you PAY the tax.MYTH: It's easier to sell your home with a lease.FACT: This would be true if you owned your solar system, but it's the furthest thing from the truth when your home buyers discover that they have to take over your remaining lease payments (if assignable and qualified).The solar industry also boasts that solar panels make residences more appealing to potential buyers and boost a house's value.

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.
