I am considering doing a 1031 exchange for two properties (1) a SFR ($230Kish) I will turn to a shor term rental (STR) and (2) about 27 acres ($200K) of raw timber land I would subdivide and develop into more SFR-STRs within the next three years. 

Has anyone had experience with a Boston-region prefab building company for multi-family development?

As for Zoning, I gave a call to my friendly town development team today and they were extremely nice and helpful.

I immediately identify wrong moves and missed opportunities that had the borrower been educated ahead of time, they would not be in such a position.My advice is the 5 PsPrior Planning Prevents P_ ss Poor Performance  It's what you do in advance as well as what you do after the purchase, that collectively over time will net more wealth.

Investing defined:  expend money with the expectation of achieving a profit or material result by putting it into financial schemes, shares, or property, or by using it to develop a commercial venture.  

.- The 45 day timeline to identify up to 3 properties, 1 of which I absolutely must purchase (required by the 1031 exchange), is obviously a very short timeline. 

I've spoken to a few sellers with enough equity to develop a relationship but some of these FSBOs are smart.

First thing would be to identify what state you want to invest in.

If something breaks between pre and post walkthrough its far easier to identify the tenant causing the issue.Tenant screening is important; some folks have suggested some ideas to help.

In my opinion your first step is identifying your team.
