If you are not getting showings it is likely you home is priced higher the than the current market will bear, for a home of your size, location and condition. Of course this assume you are in an area with a robust real estate market, if you home is in a very rural area or is priced in a range that limits the number of potential buyers it may take a little longer to get your home sold. Assuming you are listed in your local MLS with photos that accurately depict your home and there are no blocks on your showing schedule you should be getting showings and offers if you home is priced correctly.
