There are several cost-effective ways to increase the value of a home. One of the simplest and most affordable is to take care of the front landscape by mowing the lawn weekly and pruning shrubs and trees. Adding mulch at the start and end of the season can also enhance the curb appeal of a home. Painting the interior and exterior of a home can also increase its value, with the average cost to paint a 400-square-foot room being around $1,000 for a professional job. Another way to increase a home's value is to make it more energy efficient, such as by upgrading appliances and installing smart home technology. Finally, cleaning and decluttering a home can make a big difference in its perceived value, especially when preparing it for sale.
