Closed on purchase of the property. The sellers won't move out.

[Andrea Bailey]

I looked all through the forums and didn't find anything similar to the situation that we are in: We closed on a property on 6/30, the sellers negotiated 10 extra days of possession of the home because their next residence wasn't ready. The real estate co has a short term lease agreement that all parties signed to allow for them to stay. Wednesday of last (7/5) week my Realtor got a message asking if they could stay until August 1st, which we declined because we have contractors lined up all this week. This morning (day we are supposed to get the keys) my agent gets a message saying they won't be able to leave for "at least a week". These are the SELLERS -- they have our money and the house! Has anyone ever had this? Any advice? Thanks in advance!
