There's nothing wrong with asking St. Joseph to pray for you, in order to sell your home. But burying his statue crosses into superstition. The listing eventually gets around to saying that:
Selling a home or know someone who needs a little help? Ask St. Joseph! He's helped thousands! This best-selling home sale kit includes one 3.5" plastic statue and laminated prayer card for prayer as he's buried in your yard. For centuries people have prayed to St. Joseph for his help. In more recent times it has become common practice to bury a St. Joseph statue to help sell your home. While customs vary, we have found that it is your faith and prayers that matter the most, not where or how you bury the statue. Pray to St. Joseph daily and witness the power of prayer!And this company is not owned by or affiliated with the Church.
