Well-kept lawns and tidy entryways boost home value and attract buyers, studies confirm.

First impressions matter, and poorly maintained lawns, chipped paint, or cluttered entryways can turn buyers away before they set foot inside. Studies show that homes with strong curb appeal sell faster and at higher prices. Even small efforts like mowing the lawn or adding plants can elevate a property’s exterior.

Bold colors and eccentric décor choices may deter buyers seeking neutral, move-in-ready spaces.

Vivid colors, quirky wallpaper, or unconventional fixtures might reflect personal style but can alienate prospective buyers who prefer neutral palettes. Overly personalized interiors can make it hard for buyers to envision themselves in the space and may require costly updates to appeal to the wider market.
