This has taken longer to establish but you are exposed to a greater number of people including international listing sites and being in New England you might have success with marketing to Europeans who travel here.

One thing is to select some form of a corporation company or a LLC depending on your personal wealth and to protect you personally from any of your action that may have a lawsuit involved.  

Is there any liability in wholesaling that would require corporate protection?

Going forward once i start signing agents on, how do i want to structure my llc ( s corp c corp or sole proprietor ).Also if i plan to do property management is it okay if that money commingles with my agent commission splits?

You would have to file as a partnership or s corp.Every state is different, but in most states there are minimum taxes due on S Corporations.

@Debra BeeIs your property in a business such as an LLC, S-Corp or C-corp?  

Another thing you might want to do before investing is to form some sort of a corporation or a LLC.  

Or should we just form a blanket corporation (or group) to encompass all of these aspects until we've grown large enough to split into the various entities?  

Excuse me but I hate corporate america.

Corporations blindly buying properties.
