Selling a property with "Subject To" Buyers

[Bobby Vernazza]

Hello Fellow BP'ers,

I just listed one of my flips this past weekend and had the first open house on Saturday.  It was a huge hit with 83 people going through the house and subsequent showings throughout the proceeding days.  However, as of now, we have only received 1 offer which is going to expire tomorrow.  This is a full price offer however, the buyer wants me to pay 6000 in closing costs and the offer is subject to the buyer selling their house.  They currently have a pending offer and are simply waiting on an appraisal for their house.  However, I am not too sure how long this will take and I will also have to wait for an appraisal of my house to be done as well.  I am looking to sell this house ASAP and get rolling on a few other properties.  Does anyone have any words of wisdom about these "Subject To" offers?  I am a little hesitant to take it due to the fact that its going to take an undisclosed amount of time to close, yet I do not want to decline this offer to only receive lower offers from then on.  Plus, if the buyers pending offer falls apart, I am going to be stuck waiting on them to sell their house.  Any insight that anyone has will be greatly appreciated!
