HM is right, St. Joseph sells houses. It is recommended that you bury him upside down, facing the street - I've also heard to put him near the For Sale sign. He's worked for me and all of my family.
Also, the usual tips. Bake something sweet before showing. (or dab vanilla on the light bulbs - I like the baking thing better). Feng shui - put live flowers around the house, especially in areas where you'd like to draw attention.
You've got plenty of people thinking good thoughts for you - this will happen.
