GC Recommendations for first investment property - Marlborough MA

[Ryan Judy]

I have recently purchased my first investment property - a two family in Marlborough, MA.

I was somewhat lucky that the first floor came already rented with a long term tenant. The 2nd floor was gutted by the previous owner who gave up on the reno. There is a large attic I would like to convert in to a studio apartment if I can make the numbers work. (have already had an architect do plans)

Have met with a few contractors that I found off Home Advisor / Houzz , but keep feeling that they are too targeted towards retail / consumer jobs . I don't need design centers and fancy sales presentations, I'm looking for someone with more experience contracting for investors. 

I would appreciate any recommendations for contractors that fellow Bigger Pockets investors have used and were happy with. Thanks!
