I am a member of my local NAR and we have CMA software that allows me to do CAM's anywhere in USA.

Mostly because a lot of the 4-plexes here where I cam in KC the landlord pays some or all of the utilities which tear into cash flow.

(Police had trashed his apartment and checked him into a Psychiatric unit for Observation, when other Tenants complained he was a sex offender and had been stalking their children)

Well, just about 20 seconds of searching the web and found this regarding how birddogging is clearly illegal in the state of Washington as they consider a birddogger to be a broker and must be licensed.RCW 18.85.010:(1) "Real estate broker," or "broker," means a person, while acting for another for commissions or other compensation or the promise thereof, or a licensee under this chapter while acting in his or her own behalf, who:(e) Engages, directs, or assists in procuring prospects or in negotiating or closing any transaction which results or is calculated to result in any of these acts;then there are exceptions to this rule (although none apply to birddoggers):RCW 18.85.110So, according to the state of Washington, accepting ANY (commission or flat fee or chickens or cattle or sex, whatever) fee makes you a broker.......as I stated before, one should check the laws regarding it in their state first.

Honestly, whether they make enough income for the rent, and whether they have any violent felonies/are a sex offender is all that should matter.  

Being on probation for recent sex crimes is.
