Got my ACRE designation just days ago and already have 2 consulting appointments but I have a question.  I will be asking for a set amount up front as a non refundable deposit but as for the remaining balance (if they choose a program other than commission) I will be expecting it at settlement or 3 days before they remove their property from the market, but am concerned that makes for an open ended contract since they can keep the property on the market with no intention to sell for months or even years to delay paying the balance of my fee.  Any suggestions on how to overcome this dilemma? Would appreciate any advice on this matter but please help me soon I only have 2 days before I will need these answers. THANKS!
