Lesson learned on this most recent deal: Make sure the sellers start to look for a new place as soon as you start the short sale process! If the bank only wants to give you two weeks to sell the house, your sellers may have trouble finding a place.
That’s cutting it close for them to get out and find a place if any are still available. You could try looking for some sort of rooming type house.
Who knows maybe work a deal with a local inn or motel for a short term stay until they find a place. This is a tough one but thats I could think of.
