Do i need a contractor for my fix and flip (Massachusetts)

[Igor Komerzan]

Quick question:

Does anyone know what the laws in MA are regarding doing your own work on fix and flips, and when its mandated to have a licensed contractor? My father has been on the carpentry trade for almost 20 years (no Construction supervisor license) and i am also pretty knowledgeable about the trade, the plan is to work on the project together. I have a home improvement license, but not a Construction supervisor license.

I plan on buying my first fix and flip and plan to do as much of the work on it as i can. Electric,Plumbing and HVAC i wont touch. I will have licensed professional do that. But what about things like knocking down walls, building new ones, window replacement, kitchen remodel, etc... do i need to hire contractor with a Construction supervisor license?

Anybody with experience doing their own work on fix and flips, or contractor that know would be greatly appreciated. 

Thank you
