New electrical, new windows , siding , roof , paved 14 spot parking lot. , New handicap accessible bathroom on both sides etc....Owner is going to list at $429.

To top it all off the sellers agreed, in writing, to have a professional look at the electric and circuit breakers and baseboards in every room and fix/replace anything that needed repairs and provide a report stating it was all done and cleared.

If you live in an expensive area it makes a lot of sense to buy somewhere where you have more purchasing power and less risk. 

You have the deals and are going to be doing all the work, so you hold the power.

My day to day job is as a critical facility engineer for a data center, with my specialty being HVAC and commercial electrical. 

Could, if it works the way we think it's going to work, be a hell of a powerful thing...

We are huge fans of solar and put it on our primary residence, the numbers make sense for our purpose but I would have a hard time justifying putting it on a rental unless it was a MFH where I, the landlord, payed the electric bill.

That is usually enough to remind people that someone has to pay the electric.

Mostly cosmetic items in my opinion (new flooring, painting cabinetry, fresh paint, electrical and plumbing fixtures) etc and one bathroom is having a completely new tub, shower body (+ finishes) cement board walls, waterproofing and tile work. 

Of course, we will be having our local lawyer take a look at the lease.I'm hesitant mostly due to the overwhelming legal power and experience that this tenant would have compared to our small LLC.
