3 days from closing seller now wants "seller rent back" option

[Eric P.]

We are closing on our first house in 3 days.  Obviously this is a stressful time for us only made more stressful by the seller wanting a very fast closing (divorce) and us trying to make everything happen in as close to 30 days as possible.  We are now fully packed, we've told our current landlord we will be out in 4 days and hes been showing the place to new tenants,  My wife and I have put in the time off from work and we've got the movers all set.  Now the seller wants to do a rent back.  I feel like there is just no time to do this properly and get all the paperwork setup and be sure we are fully protected.  I feel bad, but I think given the short notice this would be foolish for us to allow.  Thoughts?
