When you think you might be selling your house soon, average your utility costs for the previous 12 months and have it available for agents and prospective buyers to see when looking at your home. A lot of people like to know and it makes you look good to have information available for people.
Be careful not to post comments on social networks that might adversely affect your negotiations.
Your closets should be cleaned out to half full so buyers can envision their items there. If needed, put some of the clothes you're not currently using in storage. Don't let your closets and shelves look like they're overflowing.
