using Comm real estate broker vs Residential broker

[Daniel Okeefe]

I own a commercial property in Mass and actively looking to sell. Been dealing with a commercial broker ( nothing signed or legal binding) and because of certain circumstances i wanted to start out and treat this as a pocket listing instead of the MLS. The property is located in a town that has approved an overlay zoning district which would allow Residential/ mixed use and is close to a developing downtown area which has drawn a lot of attention to developers. So unrelated to the broker i been taking to, i recently had unsolicited contact by another broker that knows a client looking for exactly my kind of property and knows the area and has given me an offer at the price i was willing to sell. What kinda strange is this unsolicited broker is officially disclosing that she is working on my behalf and has only asked for a 2% commission and would i be willing to pay that ? 2% in a commercial deal is darn low but suspect she is a residential broker, Of course i will find out for sure but my question is what perils lay ahead of me using a residential broker vs a Commercial broker in a commercial situation.. any thoughts or advice would be greatly appreciated
