But I know there are some uses where it makes a strong case to outperform traditional developing and when the industry works out some of the initial kinks in design, manufacturing, and transporting I think there is tremendous upside and possibilities. 

I'm a Boston area multi-family investor and fed up with the landlord-unfriendly laws here.  

@Oluwasegun Oluwadele Try Boston National Title out of Plano.

Plumbers and builders get discounts there, and often pass most of that savings onto you (but not all, they have to make money on it if they're going to guarantee the work for any time and transport the stuff for you).

Nearby cities with universities and good transportation to/from Barcelona will offer higher ROIs in the short term.

I am on my second house hack just north of Boston.

Can anyone recommend any structural engineers (or firms) that handle this size work in the greater Boston area?

yup MH dealer would probably be a good thing.. then buy them direct from factory. trying to find used MH is a full time job.. then you have to break them down transport them then put them back up.and they are just maintenance hogs..

Looking back, Maine saw record summer bookings due to urban exodus from Boston and New York trying to escape the a record hot July and now record rainfall all summer has broke a regional multi-year drought pattern, which appears to also be extending New England foliage another several weeks, which is helping (somewhat) offset losses in ADRs due to the a longer autumn season. 

The bill goes before the Transportation, Housing and Local Government committee on March 1.
