It depends on client (you) and jurisdiction.

Not an Emotional Support Animal (ESA). 

Where/how do you get the corporate clients? 

The HUD FMR is higher than I think my area will support.

(I don't really use it the way other realtor's do to sell and help clients buy).

I always went above and beyond the typical agent duties by getting very involved in the due diligence, dealing with county/ city planning and zoning etc, for two reasons, because I loved it and to help ensure my deal would go through by providing as much information to my client as possible to help them make a quick and intelligent decision.

I've helped several clients purchase condos in Scottsdale in communities that explicitly ALLOW short term rentals per the CCRs.

If this isnt a scam and your client is actually having trouble sounds to me the money he is trying to move isnt legit.

May be save him 3% because you don't have an agent but listing agent commission is covered by agent listing agreement whether he brings the client or someone does.
