DIY renovations can increase home resale value when focused on cosmetic updates that require less than forty hours and a small budget. Cosmetic projects like painting, lighting updates, and staging can make your home look bright and move-in ready, which buyers notice most. However, for structural, electrical, or plumbing work, hiring licensed professionals is essential to avoid delays and protect your budget. Prioritize quick, clean improvements to maximize resale without risking your timeline or sanity.
