Bank not accepting appraisal

[D.j. Wischmeyer]

Hello BP!! First time buyer here. I have two (1/1) duplexes under contract with a seller here in the burbs of Cincinnati, Ohio. The cash flow on them looks great, the appraisal came back for over the amount I am paying for them (107K each). I plan on putting 25% down to lock in a 3% 30 year rate from a local portfolio lender. Yesterday my bank rep called me and said the underwriter 'thinks' I am overpaying for the properties. What?!?! I don't understand that at all. I have a good relationship with the seller and all the numbers are phenomenal, the appraisal echos what I am thinking. I asked what he thought I should be paying and they said what the seller paid for them which was 20K less. First off does this make any sense at all what am I missing here? Second how do I handle this with the bank? 

Thanks BPeeps!! Appreciate the feedback in advance.

Well, it's hard to know if it's a good deal without seeing numbers. Can you tell us the purchase price, rent rates, age of the units, etc?

You can always take the information to a couple other lenders to see what they say.
