Look around sill plates, joists, any load bearing wooden beams, etc. If you can see where the termites have left their trail, dig into the wood with a screwdriver and see how much wood they’ve eaten out. The most obvious sign of structural damage would be sagging floors, where the underlying support has been eaten away. As far as determining the amount of damage and the cost to repair such damage, you should take a structural engineer/contractor with you. Good luck!
