I'm making an offer on a for sale by owner home. The owner has already moved out and I am ready to move in.

What should I list as the closing date? I have been pre-approved for the loan, but need to finish the loan process and the home needs to be appraised and inspected. I want to give myself enough time to finish what needs to be done, but not too much time where the seller may want to back out. Any suggestions would be appreciated. Thanks in advance!
