Should I expect unreasonable fees from a Realtor?

[Rob Douglas]

So within the last month I've connected with a Realtor who's willing to mentor and assist me as I begin my journey in to wholesaling. 

I connected with this individual via a local meet up they host. I've attended multiple and feel very comfortable with the information/knowledge they've delivered. It was on par with many of the things of heard and or read to this point regarding wholesaling/investing in general. 

During this time we've establish a great rapport where they are open to providing me with lists of properties with equity. This would save me hours of time in regard to driving for dollars (I would imagine) and money as I wouldn't have to spend cash on marketing right away. 

For doing so I'm willing to split proceeds from any deals acquired (naturally). While I understand anything can be negotiated verbally or via written agreement, are there any cost/fees that are standard for doing business this way?

Are there any rules of thumb that I should follow or expectations I need to understand while working with Realtors in this way?

Any and all feed back you guys provide would be greatly appreciated!

Respectfully,

Rob
