I am worried that over time the house has settled and now there is a problem with moisture. In these pictures you can see that the sidewalk and the side of the house is divided by a row of cinderblock. Im not sure why. We bought this house at auction, so it did not need to pass inspection. We have made improvements and now want to sell it. I think that there will be a problem with the soil line and the bottom of the siding being less than 6 inches apart. Additionally, when it rains it seems the water accumulates in this small area (because the cinderblock) and the fact that the house now sits lower than the back yard that slopes toward it and it sits lower than the driveway. Water goes under the house. In these pictures its the area to the left of the doors, and closest to the home on the left side of the blocks. Advise?
