I have heard that people having similar problems selling their house use a statue of St Joseph to speed things along. I found an inexpensive one on Amazon and thought I would give it a try.

It comes with a prayer and instructions. All for less than $10! It's worth a shot, right?
I waited for the ground to thaw and dug a hole by the front steps. I buried the statue upside down, as instructed. I said the prayer and then one more specific to me as I really want this house to go to a family that will love it.
When, yes, I said it, WHEN the house sells, I am to dig up Joe and take him with me to the new house. Not a problem. He can come with us. I just hope it is soon.
