Finance approval, shop around or use your current bank?

[Keegan Mattick]

So I'm almost ready when it comes to credit to start making things happen.  I have a good amount of savings, $15k, always adding to it.  I'm looking to get a multifamily duplex or fourplex.  Is someone more likely to get approved for a loan through their own bank, or would random banks be just as likely to work with them?   

I'm currently looking in two areas, Killeen, TX(where I reside now), and Lawton, OK(where I move to in July for work).  I'm sure location makes no difference, but there it is.  Thanks in advance for any info.
