This lonely corner of the world is ripe for the picking after the current real estate hot spots dry out so lets get a leg up on them and make our small towns beautiful in the process.

What type wet/dry?

My concern is that with COVID changes are more students studying remotely and drying up the market for student housing?

Success stems from finding your drive.

I think that the market for short term rentals up here in the summer is great but in the winter it mostly dries up.

While I hope to purchase it, even if I don't this will be a good dry run.

Especially if they are dried first before you install them.

The only way the sale wouldn't go down would be if there some obvious contamination which there isn't, or a bad cleanup job which could be fixed; the offer's pretty cut and dry in that regard, and I know others who have gone through the process with no issues (none of them sold a residence, they were just holding raw land). 

Dry-cleaners of course can pose a significant contamination issue with a property, but would a regular self-serve laundromat have similar contamination potential?

For joists you are looking for anything with dry rot, bowing/splits in them, or sistered joists (shorter joist screwed/nailed into the other for support).
