Quick U&O Question

[Mark Beekman]

I've never rehabbed a house in a township that required a U&O, so I suppose I've been lucky in that sense. I am, however, currently looking at a property in a township that does require a U&O.

My main question is: How long is a U&O good for? In other words, if in an auctioned property where the buyer is responsible for the U&O, and one is received soon after closing, can that same U&O be "used" again after the rehab when I resell the property a short time later? Or, would I have to get another one?
