One option is to have a local attorney there be the agent. 

Sarah, I am a small local direct lender in the Houston area.

Both are local investor associations with plenty of vendor members that are local to us. 

I am not sure how you are intending to manage, but beware the local labor pool is not the greatest and I think you may have some issues finding either decent management or finding decent workers if you intend to self manage. 

They did give you info that they love your place, plan to stay forever, and accordingly you should increase the rent $250 per month if allowed by your local laws for the aggravation of dealing with them. 

The local rules and regulations for building in our area is what is keeping the volume of building low.

If you are planning on investing in Maine, make sure you work with one of us realtors that understands investing and knows the local market so we can advise you properly.

Labor, materials, insurance, interest, local property taxes - yes.

I would suggest you find a good local hard money lender.

If not you, where could I get this type of mentoring and learning in my local area?
