Floor is high in the middle and sloped to the outer walls

Q: I looked at a house with beautiful floors, except every floor (first floor and second) was high in the middle and sloped to the outer walls. Why is this? How can this be on the second floor also? Are houses built this way?

The floors were beautiful otherwise.

A: I couldn’t even attempt an answer on this one. Most old homes without poured concrete foundations will have some movement in time. If you were buying the house, I would have it checked out by a qualified inspector, just to make sure there hasn’t been incorrect renovations done in the past or that there isn’t a termite problem.
