Painting walls, updating flooring, and adding finishing touches are recommended minor improvements to make a house look better. Painting walls will update the home's look and make it seem newer. Replacing carpeting, tile, wood flooring, and other flooring with more luxurious options will make the house look newer and more inviting. Finally, adding small finishing touches like window locks, door handles, and light switches that complement the other work will further improve the home's appearance. These minor cosmetic changes and updates won't cost a lot but will significantly change the look of the house.
