Avoid overcrowding rooms with too much furniture or personal items as this overwhelms and confuses buyers. Another common mistake is poor lighting that makes spaces feel dark or uninviting. Not decluttering or leaving rooms messy also detracts from appeal. To avoid these, keep furniture minimal and functional, maintain clean surfaces, and use warm, consistent lighting to highlight best features. Clear sightlines create flow and help buyers imagine living in the space, making your home sell faster and for higher offers.
