Seller Occupied After Closing

[Dustin Griesing]

Recently closed on a property in Michigan with the seller maintaining the ability to occupy the house after closing.   There is no specific language in our purchase agreement regarding the transfer of keys. 

Seller is reluctant to provide the keys prior to the transfer of occupancy date.  Though I don't anticipate needing keys and won't experience any damages ahead of this date, I'm uncomfortable with owning an asset that I cannot access in the event of emergency. Hindsight I wish this was stated in the purchase agreement, but foolishly didn't anticipate this being a problem. 

Anyone have any experience? Wanted to check here before calling a lawyer which is where I fear this will end up.
