Typical bait & Switch tactic! Then they say that the "good faith estimate" is just that - an estimate made n good faith but which you can't hold them to.
(as a guide here are the current average rates - National Averages: Low - 6.00% Average - 7.53% High - 10.75% )
We nearly fell foul of the same tactic and now have a friend who works in the mortgage industry who told us to be aware that most companies try to use this trick. If you want to PM me I can give you his details so he can perhaps give you some solid advice - no strings or anything.
I don't know what to suggest in view of your timescale deadline but if your credit history is as good as you say there shouldn't be any problem whatsoever in getting yourself a great rate somewhere else.
Here are a few examples of “bait and switch” tactics to avoid:
Advertising low interest rates and points, but making it up with undisclosed very high closing costs. An extra, undisclosed $1,200 in closing costs and fees is the same as a discount point on a $120,000 loan! Some lenders that advertise low interest rates have huge fees that serve as hidden discount points.
Offering a “no closing cost” option and making it sound like there are no loan fees. You can get a “no closing cost” loan from almost any mortgage lender if you choose to have a higher interest rate or a larger loan amount. This is not necessarily bad unless it is presented in a deceptive way.
Advertising a low sounding interest rate and not disclosing high fees to you until after you have paid a non-refundable “application fee”. An honest and ethical mortgage lender should not have to collect an up-front application fee that you can’t get back if the deal turns out not to be as good as you first thought.
Advertising for refinance that claims “no out of pocket expenses” without explaining that your closing costs are either added to your loan balance or the loan has a higher than market interest rate. Again, not always a bad idea, if it is properly disclosed up front in the ad. Otherwise, it is a “bait and switch” tactic. There are no free lunches!
Advertising interest rates and terms that are not really available. This is a very common practice in the mortgage industry. Mortgage lenders who advertise their rates know that they only get your interest if the rate they are advertising is the lowest. Consequently, many will offer a low rate that they cannot actually deliver to you! They avoid the legalities of false advertising with numerous disclaimers. “The rates had to be submitted days before going to print and those rates are no longer available.” (They never were!) “The rate quoted was for a loan larger than yours.” (Or the lock period quoted was shorter than the one you need. Or, or, or ….. It’s always something.) If the rate looks better than the current market dictates, they cannot deliver the loan and you should not reward that lender with your business!
