What would you do in this situation?

[Jason Muenchow]

Hello all. Thanks in advanced for the replies. 

So here is my situation. My day job is doing social work. My side job is being a realtor. I have a lender I like to work with and is always helpful with my clients. I went through him to buy a triplex last year. I wouldn't say we are friends...but have a good relationship. 

Ok, enough of the background...I've got two duplexes under contract. One will be a primary, the other will count as an investment. He quoted me 4.25 on the primary and 5 interest rate on the investment.

Fast forward a week...I was hosting a open house for one of my listing and a different lender walked in and was peddling his product. He asked about my situation and I told him about buying the two duplexes. He asked me to give him a chance to show what he could offer. I didn't think much of it and said sure why not.  He got back to me with 3.75 on the primary and 4.75 on the investment no points. 

I went back to my original lender and said...hey this guy offered 3.75 and 4.75...I like you and would prefer to go with you...can you come close? He came back to me at 4.125 for the prim.

Now I'm at a loss of what to do...most investors will say take the better numbers...but I might destroy this business relationship. Maybe I'm just looking for confirmation I'm not doing the wrong thing. I've already bounced 100 questions off my original lender. Just feel bad not going with him.
