Here is what I know for sure: there are lots of websites where counterfeit paperwork making their "service pet" look legitimate are available for dishonest people.

You can also work directly with smaller venues for a personal code or deal.

You are handcuffing them when a more legitimate buyer comes along.Instead a seller might want to give a wholesaler an (option contract) or have a (right to continued marketing clause).

My first thought would be to make sure the animal was a legitimate service animal. 

Quote from @Scott Mac: None of those are legitimate excuses.

Except for the few who have legitimate mental illness and the rare "down on their luck" person, most of those guys/gals with signs are just lazy scammers.

Postlets is free and will syndicate your ad to other real estate venues like zillow, trulia, social media and more.

I am shocked at their response to a legitimate concern regarding their software and will actually be shopping around for a different software company.

However I do feel that having some skin in the game and looking at investing not as a hobby but as a legitimate future forces you to put the effort in to succeed.
