While showing a property today, I noticed that there was a sump pump in the corner of the basement that looked to be a part of a waterproofing system. Since 95% of the basement was finished, it was not possible to know if the waterproofing went all of the way around the foundation. That's what property disclosure forms are supposed to tell you.
I then started looking closer at the unfinished area near the furnace and after moving a some stacked items, I noticed what appeared to be some mold across the bottom section of the back-side of the drywall. Obviously with the basement being waterproofed, they previously had water in the basement.
When looking at properties, make sure you "carefully" check out things whenever possible, so that you can get a better idea of the true condition of the home. Now don't try moving an entertainment center or start unplugging the computer or stereo system, but you can do many non-invasive things to see what the home really has to offer.
I always look under rugs. Once in a home, I pulled up a small area rug and was I ever surprised. The hardwood floor had a hole in it big enough for most people to get their shoe stuck in it or at the very least, a strained foot.
I also do a lot of looking "UP" to see if there are any water stains or major cracks on the ceiling or walls.
Now I believe most people are honest, but it is amazing what one sees when showing homes.
What have you found lately by keeping a closer eye as you walk through homes?
