Should I, if so how?

[Cameron Ellis]

I have a purchase contract on 5 properties, w/ a selling price of 700k in the suburban outskirts of Memphis. I have spoke with a couple of potential buyers and thy seem interested. I received a call tonight from a gentleman wanting to put a option contract and also a non disclosure contract on the properties for 60-90 days. This will take away all right for me to market this property and sell it if a serious buyer comes before those 60-90. This gentleman said during that time he will market the property to his potential investors which immediately rung a bell. I have no problem working with other wholesalers I actuall love it but for someone to put a hold on a property for that long is crazy. Bp what would you suggest I do
