Using a RE agent to buy FSBO or off market property?

[Tom V.]

Just wondering what the typical protocol is for this situation, and how the RE agent gets paid.

Flat fee? Percentage of sale price?

I have a great RE agent who is also an investor. I found the properties myself, but since I'm a newbie I'd like to utilize her expertise in the buying process. I'm going to contact my agent about it shortly, but just wanted to ask the smart people here first so I have an idea what to expect.

Thanks in advance for any advice you can provide.
