Things to look for while entering the crawlspace of a house I'm considering buying?
Some things we found under our crawl space that you can keep an eye out for:


Joist hangers weren't secured to code, not enough nails.
Insulation wasn't properly secured and was sagging.
If the crawlspace is part of an addition, make sure ducts and vents arn't coverd up and carry through to the exterior of the house. Make sure any vents aren't leaking air and flow is good.
