Do they charge a fee since there is no commission on their end?  

Wholesale assignment fees are higher than commissions even though they could still use a Net listing agreement.

Was paid sales commission to sell it to myself.

I know Reunion West is a very STR friendly rental area with access to ample amenities.

Although it isn't some miraculous contract that will hold a buyer hostage, there can be repercussions to you and/or the agent you eventually earn a commission with.

Having a real estate license, I would credit the commission payed out I would receive for being my own agent towards closing costs for the new property.

I am selling through a realtor since I believe the commission is worth it.

If they refuse, file a complaint with the state commission.

(if so, salary or commission or both)2.

I'm also considering finding a seller that would pay more than me to help my father-in-law out and perhaps get a wholesale commission that I could use on my next (ok, first) brrrr, but I'm not sure the best way to validate a fair price or know what a fair wholesale commission would be.
