Shaky floor

[Jonas Beiler]

I was in a house yesterday that had very unstable floors in two second story bedrooms. Sort of like a trampoline effect when you jumped on them (maybe not quite that bad but it was bad enough that you could easily see the ceiling bounce when you were downstairs in the living room and dining room. House was built in 1920. Stick built. Seems solid otherwise. Could this possibly be termite damage? What is the best way to fix it (providing it isn't termites)

I don't own the house. It is on the MLS and seems like a good opportunity if i can overcome this problem.
