Remove any unnecessary pieces of furniture and you will immediately make your rooms seem more spacious. Traditionally, viewers pay most attention to the bathroom and the kitchen, so take care to ensure that these rooms appear bright and clean. Treat any serious problems such as damp or dry rot before you put the house on the market. Do not hide their existence from viewers, as they will simply be uncovered at a later date when the property is surveyed. Tidy the garden, particularly at the front of your home, as this will have a huge bearing on the viewers first impression as they drive up to the property.
Window boxes can add colour and are fairly inexpensive.
Pay attention to detail. Fix faulty door latches and squeaky hinges. Make sure that windows do not stick. Mend guttering and fix loose roof tiles. In the summer, open windows and turn up the heating in winter to make the house cosy and welcoming.
