Do the same there and see if you find any common brokers who list a handful of the size property you want and connect with them. 

Good morning GP, If your property sells for $300,000, your "net sale price" after deducting your routine selling expenses (brokers commission, title, escrow, closing attorney, documentary transfer tax, etc.) will likely be around $275,000 (ish). 

I recently passed my North Carolina Broker's exam (excited!)

It's free to talk to a realestate agent/ broker.

This is pretty easy to obtain from calling a couple brokers, but could vary greatly between what you are quoted and what seller is paying.Age and condition of building?  

At this point I had found I was pretty good at finding and managing tenants so I partnered with a real estate broker and started managing for other investors.

Brad is one of the biggest players there, broker, investor, restaurateur. 

I am a real estate broker and have access to market data for valuations.

As of now, many potential sites were either identified by broker/developer or too expensive to acquire.

Also keep in mind that it's not legal in the US for someone to get paid a commission -- or be given equity -- in return for raising capital (unless they are a licensed broker).
