Terraced houses (take 1)
Including a useful dog field

 
These cheap houses were built in 2014. They have thin aerated concrete inner walls, slightly sagging roofs, PVC plastic door- and window frames, and plenty of plastic foil to keep them free from moisture (out of sight). Still, with today's prices you can sell them for almost twice as much.
