It might be that the moisture is coming from ductwork that's not insulated, since it is in an attic.

Hello All,I'm working on closing my first rental property and everything was going according to plan until the termite inspection revealed prior damage and higher than normal wood moisture content in the crawlspace.

As to "(if) we don't run out of water" I'm betting that one of two things will happen sometime in the future, 1) it will be decided to pipe the Columbia river from Washington the way oil is currently being piped across continents, or 2) a process will be developed to desalinate seawater cheaply or a process will be developed to bring moisture out of the air which can currently be done on a small scale.

The HVAC system was laying on its side underneath the house and moisture, flooding, humid Texas environment really did it in. 

, security cameras, moisture sensors etc might pay off) a quick call to your insurance agent to ask for a list of things that will reduce your premium is usually worthwhile.

The real estate agent that I've been using (who is fairly well versed in investment purchases) suggested placing a dehumidifier in the basement to help control the moisture.  

Hi @Norbin Cruz The spray foam is a great idea(as long as it’s not so tight that moisture can’t escape the house.)

i thought it would be a cool look, but obviously, moisture could be an issue. 

We live within a mile of the beach, so moisture and mold can be a problem.

Is there a foundation issue which is causing the water/moisture mold?
