Some will simply ask the buyer to purchase and additional $10k coverage but some, like the one we were working with insisted on a double closing.Long story, shorter version: We now have a double closing in the works, us buying the property from our seller at $160k, then same day simultaneously selling to our end buyer for $180k. 

But not in Double or Simultaneous closings.I am not sure if this applies to you are a Broker or not.

All you need to do is find a real estate lawyer in your market and ask if they know how to do a double close or simultaneous close.

@Mark Maire A double close is two simultaneous closes.

If they say you qualify, then set a budget including paying for the house and paying down the debt simultaneously and then go buy a house. 

Your deciding factor is how many simultaneous users do you have for QuickBooks?
