If my landlord sent me something like this (with the over the top “nice” overtones) is throw it away

The 3rd one is a heavy rehab though six figure budget and i got really cheap. 

You can find a cheap duplex that needs some love.

That being said, we focus on micro units (1-2 guests max) and have no problem having our units booked every weekend with scattered weekdays.The sad thing is we used to be at nearly 95% occupancy in 2017-2019 but once everyone started joining the party and our city started throwing up tons of hotels to keep up with tourism demad, we dropped to more like 65% occupancy.Keep your head up, man!

I have also negotiated to bond around future possibilities   These bonds use to be fairly cheap. 

I often wonder if the remote location (20 minutes up the mountain) is a turnoff and travelers are starting to prefer motel-like accommodations that are close to the main highways.Houses in the middle of the woods with no view, houses that are non-cabin style like they belong in a normal major city suburb, no game room, no deck to take in the view, no hot tub, no area for a fire pit, no room for extra activities like corn hole or throwing the football, poor driveway, steep entrance, tons of stairs etc.

I will also throw out another idea.

All in, I believe the entire build will be ~$300,000 (I haven't tallied lately) but we've been able to keep it cheap because we're doing a lot of the interior finishes ourselves.

If that is the approximate time frame, then throw them a bone and move on.If they have been unable to use the bathroom since the water incident because it was declared unhealthful, then it would have been much better to have made an insurance claim. 

Personally I would just consider either lease it cheap to nearby farmers, check with another solar developer if the reason is not prohibitive or sell at a loss.
