The main concernas mentioned my seth is water and moisture problems.

Police shut that one down in a raid too. normally they break a big hole in the house and tap into the electrical wire before the meter to steal juice. and the excess moisture destroys the plaster/drywall.my buddy was asked if the tenant can section off an area in the garage for legal pot growing. outside is -20 and he needed temps of 60F+. lol

Likely have moisture damage unless it's absolutely bullet proof.

There is a serious moisture problem that needs to be fixed.

However, I would imagine any siding that is warping and losing its integrity would present a problem, particularly in an area with the moisture that Everett has. 

- Up-front cost difference- Energy (heating) costs- Comfort- Resale value impact- Anything else that's relevantWhen I say crawl space, I mean a non-ventilated, moisture-protected (vapor barrier, waterproof spray, and sand/gravel), heated space, NOT the dirt-covered, ventilated space of old.Thanks!

Take a look at this link. http://www.homedepot.com/p/DRIcore-7-8-in-x-2-ft-x...You can also install a vapor barrier to prevent cold air, moisture, etc from coming up through.

You have to regularly inspect it.You might have a moisture problem.

You may see this moisture escape in brick that has white streaks or areas known as efflorescence.

So, you could be developing moisture damage in a major way.
