Is it a good time to buy commercial property near Boston?

[Tim Walls]

I've been looking at 5 + unit, mixed use, and commercial office buildings for sale in the Boston metro area over the past few months.  Most of what I am seeing is off-market or pre-mls properties, but everything still seems very over-priced or completely picked over.    

Do wholesalers exist in commercial like they do in residential?  

Thanks!
