Coming from an accountant (not a tax accountant, but an auditor - my wife is the tax accountant).

I don't see how you could sell what I am assuming is not your primary residence, earn a gain on it and not have to pay any capital gains taxes.

No matter where income is derived - if you are a US resident you need to pay US taxes on it. Now - I'm not sure if you'd ever get caught - but I just don't see a way it could be "legal".
