In TN, KY & GA - Erie, State Auto and American Modern are great for rentals. 

I reconfigured the floor plan to open up the space and added a bathroom.

Being a broker in this space, the lenders offering 30 year terms (true 30) are non-bank, non-depository, usually backed by some type of hedge/debt fund or other type of institution. 

Probably don't get that money back if you do that and previous owner redeems.If the barn is in good shape, maybe you can rent that space month to month for the next two years and at least get some income.   

I would find a lender that lends in that space.

I have no experience with lots and new-builds, so I am making this post to get ahead of any "unknown unknowns" that may bite me in the rear.The key theme is that I'm open to comments, concerns, alternate suggestions and insights from those who have done something similar to my scenario.

What would you do with the RV space if it wasnt getting rented out?

The idea is to do some rehab to either section off part of the house or build out a room to airbnb (also planning to start a family this year so didn't want someone going in and out of our living space).Either we can build up equity in that property to refi into a multifamliy home or get creative for the second property which would be strickly a rental.

The US Naval Academy Alumni sold this portfolio of 3 properties with combined 12,000 sf. of space, it will be converted to a boutique historic inn that will have 20 suites.

They wouldn't cover the cost of housing the tenant somewhere else, but they will compensate for the amount of space that wasn't useable during the renovation.
