Kick 'em to the curb and don't look back. 

But we got 'em!

Then they could attach pictures, documents, or other supporting material to prove their case.I've had the idea for years but am also worried about tenants with deep pockets suing the web site constantly.

You can find him on the web.  

Additionally, many unscrupulous web sites are tapping into this need for a workaround to "pet rent", additional deposits, or a no pets policy, and are marketing to people that desire that. 

I have used up my 10 free rentals for the web site rentometer,  is there a 2nd web site that I can use for free to get rent amounts?

Go get em!

And yes, there is agents in the market I advise my clients that we should not work with because if we do, it is going to blow up in our face.however if your client insist they want to work with an offer from one of your agents you identified as a poor agent.. and everything is disclosed to your seller you would still work with the butt head right.. but have very tight reins on them higher EM deposits.. ( we do that when I am the seller for certain people in our market I know that are prone to pull fast ones.. 

You can create a free web site or have it available to email anyone that asks.I also agree with @Nathan Schiess that you should always let people apply if they want.

Get rid of 'em!
