leapy88 - You will have no capital gains to report. You are shifting the future tax burden to your sister.
The link to the other AnswerXchange question (post) explains how to handle the 1099-S. Your sale price is $180K. Your cost basis for reporting is $180K. You may not claim a loss, since you are selling to a related party.
Your sister's cost basis in the property is $410K.
Your accumulated depreciation also transfers to your sister and she will continue depreciating on the same schedule you were using. She will have to "recapture" (pay tax on) the depreciation when she sells. If your sister uses the home as her primary residence, for the required 2 years, she can avoid tax on the ordinary capital gain (up to the limits) but not the depreciation recapture.
You will be required to file a gift tax return (explained above).
