Use Saint Joseph to sell a house?

A friend of mine called me today to tell me that they sold their house. It had been on the market about 8 months. She had heard that if you buried a Saint Joseph statue in the yard, your house would sell quickly. She buried it Saturday June 23, had a buyer on Friday the 29th and closed on it today. 9 days. Wow, that's awesome. Maybe I need to bury one in our yard so we can sell quicker.
