Not easy change a title company, but

Not easy change a title company. The bank with always use their title company. You can use yours, but they'll charge you more for doing that.
What I do is call the title agent, and stress that I'm an investor and plan to buy many properties. Then I ask if it's possible to reduce the closing fee a bit. I've had the fee reduced a few times. Possibly saved $200-300, total.
