..How quickly can you deliver a written commitment?...The KEY word here is "Commitment"...a year or 2 ago that was an easy question to answer. If the lender was sophisticated enough to be using automated underwriting, in most instances, they ought to be able to deliver a commitment within 24 hours. Today, impossible. period.
First of all, in NJ, you cannot use the word "commitment" without having an appraisal(its illegal), and the appraisal is going to take at least a week.
Combine that with cautious underwritering, new government regulations, and tighter credit policies, and we are realistically looking at 2 weeks to 30 days.
The good news is that the market realizes this, and expectations have adjusted. Still it is best to pick a lender that has local underwriting, and doesn't have to ship the file to East Gibbip Minnesota, and cannot even talk to the underwriters.
SUGGESTION FOR BUYERS: Get a mortgage CREDIT APPROVAL BEFORE you go shopping for a house. This is a complete underwriting review and approval by the lender just short of an appraisal. Then, when you find a house, all you need is the appraisal. This I can do in 24 hours.
