@Jim G.Per the International Residential Code if the glazing is less then 60 inches vertically from a standing or walking surface then yes it’s required to be safety glass as it’s considered a hazardous area.  

We put our first home on the market for rent $1450.00 and right away, not even a week my realtor found some potential tenants.

Off grid sounds cool to some, but it really limits your potential guest pool.

If I have a potential tenant that I like then I work with them. 

It checks all my boxes for potential.

@Heather Bailey while I live in my duplex, I have a standard Hazard insurance policy and I also carry an additional 500k umbrella policy (optional); both policies cover the entire building, but there's no separating it. 

Also 4th quarter of last year Packwood and county officially did discuss potentially regulating STR's by either limiting numbers or adding a tax to cover increases in local services that are needed. 

Potential redevelopment or ADU play. 

The investors get much more profit out of the property.Recommend having a very open conversation with your FIL, expressing your interest in potentially taking over the property from him.

There are never full photos of the mechanicals and basement and roof line so you will never have even a bare inkling of what the potential repairs will be.
