These projects can add significant value to a home, with some estimates putting the return on investment (ROI) at around 60-80%.

3. Painting: A fresh coat of paint can add a few thousand dollars to the value of a home, depending on the size of the home and the cost of the paint.

   adding more light to a home can make it feel brighter and more welcoming. This can be achieved through the use of natural light, as well as through the addition of new light fixtures.
