Based on your scenario, you should have an smooth transaction.
A couple of questions:
1. Given that close is 7/31 will they wait until 3 days prior to give me the good to close all clear?
A: The CTC is issued once the Underwriter clears all conditions. Then the file will be moved into the Compliance/QC Department and into the Doc/Funding Dept. If your loan is handled correctly by the lender, this will be issued at least 3 days prior to you closing date.
2. New construction, so will the perform multiple appraisals?
A: If the lender ordered the appraisal prior to completion, then they have to order a 1004D (re-inspection). This is where the Appraiser goes back out and verifies the unfinished items called out in the report are rectified. The cost is usually $150.00 - $175.00 which should have been disclosed early on or you can't pay for it.
3. If the houses finishes early can I push for close to be moved up?
A: If the house is completed early, then the Builder will most certainly want to close early.
Best wishes to you!
