Here is a link to the Washoe County Assessor's site where you can download spreadsheets of transactions. They are in Excel format and by default sorted by APN, but you can resort them.
If the CL post is accurate I'm pretty sure he's renting - it would be hard to do a complete sale transaction that fast.
None the less, if you need any detailed info on any of the transactions I have an account with the Washoe County Recorder and can look up the original documents pertaining to any transaction from my desk.
I agree that if the perp has moved recently, he is a renter.
