How many cfm do you acutally need? 

However, the more your brokerage knows about your off-market deals, the more they want a cut.

It definitely helps knowing that side of real estate and then you can represent yourself and negotiate the 3% commission into the deal, though remember that you will be working under a broker that will expect to get a cut of the commision, so you'll need to address that when the time comes. 

I have only heard it in joking terms.I am more acutely aware of the recent disdain in the media and government for landlords en masse.

You might be able to partner with an established broker for a cut of the revenues. 

If the property appraises for higher than you thought, he gets a cut.

Its a cute house in a GREAT school district and currently rents for $1250/mo on 1 year leases (leases same day, sight unseen, any time it's on the market).

I have offered taking a cut on my commission to get their house sold quicker, because I want to show them that I am not in it for the money.

I am sure they would want a cut for using their license.

You may have to offer more of a cut in your commissions, answer the phones more often, in order to make it worth their while.
