I'm starting to wonder how much affiliate commissions/earnings a podcast typically makes with these.  

You are a new agent and should not focus on commissions, teams, solo, etc.

Even if you offered to pay them a flat fee commission for helping you through the transaction.

That way if they leave you have room to increase the rents closer to market and can justify TI,attorney, and leasing commission costs.For this post office analyze if it is one of the top spots in town where if vacant lot's of local tenants would want it or is it an old building off to the side where would be very hard to release and at low rent?

Many locations appeared to have the tax homestead exemptions, which farther kill the cash flow.Land in Midwest- no rental income but no depreciation as well+ usually higher selling commissions +waste of property taxes.

I worry that the realtors will try to sell what would be best for them when it comes to commission instead of cash flow for me.

Crosby, A rough profit os $20K means after all costs/commissions? 

Of course, he wants the commission, but according to what I'm seeing, I don't believe he's not being candid. 

Is it common place for non-agents to write up a "referral contract" to collect a similar commission that would be due to a broker?   

How much of YOUR Broker commission are YOU giving up?"
