Capital Gains Exclusion for Sale of Rentals

[Steve Testori]

I've read that you can exclude paying capital gains on the sale of a rental property if you occupy it for two of the previous five years of ownership; does anyone have any experience with this? Any potential pitfalls?

I'm trying to decide if it's worth the inconvenience of moving multiple times - OTOH, my three properties will wind up costing about $90,000 in capital gains when it comes time to sell, and I'm loathe to part with that much cash ...

Any insights/advice appreciated!
