I just went through this myself. Here is a little advice I can give. You should be able to get something in the 3.75% range with 0.25% juice on top of it.
1) don't use a bank
2) private mortgage professionals are one of your best options
3) don't discredit online e-lenders. they will offer you the best deal, but all their customer service sucks. I was surprised the deals they offered. I could buy 1/8s off at around $1400/eighth. Not the best choice for short term investments, but worth considering.
4) some Dave Ramsey ELPs (particularly Churchill Financial) can very shady
I contacted 4 different banks while mortgage shopping. One being the bank I got my last mortgage with and another being the bank I do ALL of my banking with. Plus 2 others. None of them would get under 4.125%. They all capped right there. All the other options were getting to 3.75% without batting an eye. Maybe I chose the wrong 4 banks, but they all gave me the same line.
To your point, I should have said "Don't assume a bank will give you the best deal."
Nugdawg is the guy. He is who I use as well.
....my local Regions bank. They charged me $400 closing cost. I also quoted with Quicken Loans and their closing cost was around $4,000. Easy decision.
