Auction.com purchase,needs advise

[Kay Kay Singh]

I bought an occupied house at the auction.com and after signing the purchasese agreement ,I went to the house and asked the occupants politely to vacate the house in a week and they happily agreed and did vacate the house and now we changed the locks etc. and have the possession of the property but the closing in in about 2 weeks as told by auction.com,So my question is should be go ahead and start working on it or should we wait for the closing.
