Redo floors?

[Michael Held]

So I'm on the verge of taking the plunge and renting out my home. The hardfloors haven't been done in about ten years and some areas look pretty bad. I'm thinking I should have them sanded and refinished but friends are saying don't waste the money. I would think (hope) that I might get a better class of renter and hopefully a few more dollars in rent if I do this. What's your take?
