As a real estate agent in the St. Louis area, I have worked with a number of "wholesalers" who have asked me for info on properties they were taking under consideration.
I'd ask you guys to ask BP Member Ryan Dossey if he feels a real estate agent can provide better insight into a property than your own internet Google Search. Do you guys really think Zillow, Homes, Realtor, and other sources are providing reliable sales figures? Ever check the margin of error on their pricing? Swing those prices by 20% and you have a better idea of the "actual" price you should be dealing with in buying and/or selling.
Also, there are TONS of wholesale deals available through a realtor than your standard Yellow Letters, hit-and-hope, direct mail marketing campaign. I can dig up properties at any value that have NOT sold, for whatever period of time, that are perfect candidates to contact and wholesale.
3% for the effort in working with a realtor is a small fee to pay for the data that can be mined.
Just sayin'.
