I went to view what looked like a potentially perfect house. 4 beds, two reception rooms, decent sized kitchen, en-suite, garage, good garden, good catchment areas, and (what really seemed like the USP) and basement area that looked on the floor plan to be big enough to convert into two separate offices/hobby rooms.
DH was working, so I went.
The basement was like something from the Blair Witch Project house. It had a dirt floor, no lighting other than what came from the (creaky... just to add to the vibe) entrance door, and crumbling internal brick 'walls' that I kept thinking I'd see something move if I looked through the holes from missing bricks for too long. There were fading symbols on the walls.
The piece de resistance, though, was the multiple metal support bars throughout the basement that were effectively propping up the ground floor.
The estate agent and I both left pretty quickly. She then cancelled viewings for the rest of the day while she tried to find out if the building was structurally sound.
We didn't put in an offer.
