LLC doing business in another state

[Jochy Perez]

Hello,

Before I go down the road, I want to run this by you guys for advice.

I want to file an LLC in NH, however, it will be doing business in MA (purchases, rehabs, rentals, etc).

Are there any tax complications or legal complications? 

I do have a mailing address in NH so it would be much easier for me to go through NH. The state filling fee is also cheaper in NH. 

Thoughts?
