No what he is saying that it is better to sell off along with giving up your residency. If you eg: rent out for 2 years while you are away you will need to pay taxes on the rent and then pay the capital gains for the 2 y ears. You will need to get a specialized attorney and appraiser to review your assets 2 years back at that point in time. The attorney will withold 20% - 30% of cash in escrow etc. Pain.
Oh, okay. We weren't going to rent out the house anyway. Seemed too much a pain without the tax mess added on!
