Generally I agree with Paul Ashworth especially for the exterior but if a restaurant goes in their restroom needs are going to be a lot different than a doctors office so I wouldn't spend too much upgrading bathrooms until you have a tenant.

What about maybe sealing the vent system in the restroom sounds like its seeping thru there, or maybe a wall you can build that divides the restroomsIn the attic.

Just look at how many people say "bathroom" when they mean "restroom" or "toilet".

A lady left her loaded gun in the restroom of a church up here a couple years ago.  

And def some modernization maybe new kitchen and slightly updated restrooms. 

RVs also have added costs that can come with the requirements to have extended hours and public restrooms etc.
