This is a question you can ask your Realtor if your home is on the market. How many showings on average before a home gets an offer. What got me thinking about it is that over the weekend one of my clients made an offer on a condo the first day that it was on the market. The unit got very few if any showings.
Since only one person can buy the home it is a matter of having the right people stop by and take a tour. In St. Paul right now it will take about 8 showings to sell a house and about 6 to sell a downtown condo.
