Hi Everyone, Do you guys know about the best equipment that is not crazy expensive to detect if a wall is humid? 

Maybe they have a bette sense of smell and smell a toilet smell or a humid smell.

I see lots of cracking in the walls, pulling apart of door frames, ceilings, etc...all indicative of settling/foundation issues.The mold in the bathrooms is pretty common and doesn't scare me too much - but it appears every surface in the house is suffering from severe humidity - has it been sitting vacant without A/C, and was there a flood or plumbing leak that caused water damage?

The reason i asked about to remodel it and rent it or just flip and sell it is to know for Columbia what better, the neighbor hood are in A grade that is good , but I hear things about the city like cockroaches and humidity and less place to go out that make me think again about rent it to people.One thing I learned and correct me if I wrong , is when house is remodel and unique in neighborhood people will rent it 90% of cases.

We don't get snow, but we get a ton more water each year and it's way more humid so that's interesting.

@John Underwood from what we’ve read hardwood wouldn’t do well here due to humidity and we also like the easy install with eng hardwood since were doing it ourselves 

It also depends on rainfall and humidity. 

I figured it must be set off by the humidity of the shower, especially as the bathroom lacked a vent (it is an older mobile home). 

It is not as common and typically happens when there's water or prolonged humidity on a wooden beam. 

I think you would have a real humidity issue, as well as aesthetics, having a hot tub in the garage.I would probably either go big or go home on the game room.
