Normally, appraisals are sent into underwriting for the final approval of the loan. So, when the appraisal is issued, it may take a couple of days to get the documents out of underwriting and to the title company.
Bruce is right. You should have enough time to get everything done, but checking on the lender would be in your interest. Have your listing agent ask the buyer's agent or lender when the appraiser is scheduled to go out and when they expect documents to be at the title company.
1. Make sure they got the appraisal.
2. Make sure it got approved.
3. Make sure you got final loan approval and when will docs be sent to the title company?
You're almost there.
