weird smell- closing soon

Hi,
my husband and I are closing on a house soon. The problem is this- they removed the washer-dryer and now there is a weird funky chemical/musty smell in the laundry room. There is also a floor drain in there. Their realtor told us we should deal with it after we close. I thought that was not such a good idea. What could it be? Should I have the inspector come back?
thanks,
