Yes, the St Joseph statue REALLY works!
Just make sure you plant him UPSIDE DOWN FACING YOUR HOUSE!
You don't want to sell your neighbors house. lol
Put him in, then when house is sold and closing is done, go and fetch the little guy out the ground.
Here's what you do along with a prayer....
"Oh, St. Joseph, guardian of household needs, we know you don't like to be upside down in the ground, but the sooner escrow closes, the sooner we will dig you up and put you in a place of honor in our new home. Please bring us an acceptable offer (or any offer!) and help sustain our faith in the real estate market."
Custom dictates that once the house is sold, St. Joseph be dug up and put in a place of honor in the new home.
