I hear you but I've given this guy 3 loans totaling almost $800K, and I think he's called me twice total. Said "thank you" zero times. It's the easiest money he's ever made actually. Truth be told, I'd get much better service from someone fighting for my business. So I'm not worried about him knowing I'm "professional" in the least. I also don't think he would fight one second for me to get a loan in a non "cookie cutter" situation. But, he has all my info, he does his job efficiently, and it's hassle free. So I go back for my own convenience really.
It sounds like for the most part I should just move forward from what most are suggesting. I'll just tell him if rates drop between now and when we close, I expect to get the better rate with all the business I've given him. If it happens, great, if not, then no biggie. I just did the calculation and it's actually more important I refinance my primary home asap. I can save $250 a month on my mortgage!
