How to approach a new bank?

[Bryan Dahn]

I have several rental properties and have either used owner financing or one particular bank. I have a pretty good relationship with this bank but they have recently gotten bought out. It is a small local bank. I am thinking ti may be in my best interest to begin building a relationship at another bank. I am finishing up a full remodel on a house that is currently paid for. I plan to do a cash-out refi so I can do a full remodel on the next couple places that are paid for and need some attention. 

My question is this - What is the best way to approach a bank and explain to them that I would like to start doing business with them and that after I finish a few more houses, I would like to go back to buying more properties? Should I try and schedule an appointment? Or just show up and ask to speak to a loan officer? Are there any specific tips or tricks that you have used to successfully get a bank on board with financing your expansion?
