The process can take time and you are at the mercy of the Builder who is at the mercy of the processor.
If the spot approval did not fly there must be valid reasons. If FHA questionaire from the builder is in.. you have to wait it out. I am surethe builder wants the approval as much as you do.
Has you Mortgage rep been keeping you informed? This will be your best source of information.
This question appears to be better suited for a mortage professional. In my expertise "how long it takes to complete the process" is relative to the circumstances and as a RE professional prefer not to comment any further.
Feel free to contasct Dawn Benedickson, mortage pro @ firstname.lastname@example.org or 732.775.7765 to see if she can help. She's an upfront, straight shooter, like myself who'll tell u straight away whether she can help or not and possibly recommend alternative contacts. Feel free to tel her that I set you as her atennas will be up, knowing that I demand the same level of serivce from my associates that I give to my own clients.
