Buying a house that has been remodeled will give you some surprises. A house that has had a remodel on top of an older remodel may really give you a surprise... and most likely not in a good way. While our house's first remodel (from the '50's or '60's?) is weird, it's not terrible on its own. When the second more recent remodel came along with new landscaping, it made for a bad situation.
The warning signs were the dogs sniffing and being obsessed with weird spots around the house. No wonder they use beagles for drug sniffers or hunting dogs! Well, our Moose is a hunter. The project started with Moose catching a rodent. It was living in a gap under the siding, as we found out when we started to take things apart. Other interesting things were found as well - an oddly cantilevered wall, exposed ducting for the HVAC, a small amount of dry rot (did we catch this just in time?!), and more. Without totally rebuilding the wall, we flashed it better and are patching it all back so it doesn't house rodents and doesn't allow water intrusion.
