24. Refresh the Walls
Painting your interior walls is one of the smallest home improvement investments you can make, but it can still bump your home’s value by up to 2 percent. Painting is a perennial DIY project that really fills the space with your unique personality, though if you’re planning on selling, sticking with neutral colors is the safest bet.
Average Cost: You can repaint a room DIY-style for about $300, or hire a crew to re-do the whole place for an average of about $1,700.*
