Curb appeal refers to the attractiveness and good first impression of a house as seen from the street. It is impacted by factors like landscaping, maintenance of the lawn and outdoor garden, and the quality of exterior finishes. To improve curb appeal, homeowners should ensure the front yard is well-maintained by trimming bushes, planting flowers, and keeping the grass green. They should also focus on maintaining elements of the exterior like the roof, siding, paint finishes, windows, and gutters. Driveways and walkways should be kept clean and clear of weeds and debris.
