I'm an investor and flipper in the city, and I work for a developer focused specifically in Lowell as well.

Please be aware that all national homebuilders, and I would assume solar developers as well, will want enough time in the contract to conduct substantial due diligence, rezone (if needed), and get all required land development permits in place before closing on the land. 

I invest out of state in Pittsburgh from DC and self-manage everything, but it's taken me years to establish the right contacts, develop seamless processes etc. that allow me to handle everything remotely with confidence.

Do you plan to further develop the agent side and turn that into a full time thing?

So, if a developer comes along and buys the mobile home park you will lose your entire investment.

Also, a contractor may not be the best person to develop your scope of work! 

Best bet is likely (not absolute - everyone's situation is different) is to look at a national lender or broker that has options in lots of states - its a great development versus 20 odd years ago, with technology, internet, places like this - can have access to many more options than before (local broker or lender thats it)

They're already there and given the holiday season, probably the traffic is light, so you can chat then up for 10-15m about the area, rental class, as well as any remarkable developments in the area that would positively impact that home/area. 

Our ultimate goal is to get into real estate development along with buying rental properties.

Your development deal will look much like a flip in the eyes of the IRS since it is 6-9 months as well you'll have the short-term side of taxes, not the capital gains taxing on it.
