Adding Siding: Fiber-cement siding is estimated to recoup a significant amount of money back from the initial investment because it holds up well against the elements and is resistant to fire, rotting, and termites.
Painting: Painting the interior of the home provides dramatic results with little investment. If you decide to hire a professional to do the work, expect to pay a few thousand dollars. Painting is also a great DIY project, depending on the amount of time you have, and the height of your ceilings. If you are selling your home soon, this is not the time to make your home your guinea pig by testing out your painting skills.
Building a Deck: Everyone love decks. They’re great for entertaining, and relaxing in the sun, and can reap an impressive return on investment; but be sure to use natural or rustic wood.
Updating the Kitchen: You really can’t go wrong with remodeling your kitchen, which can net up to 83% of the cost.

However, if your house is very, very small, don’t bother on making big splurges for fancy appliances. In a smaller home, you’ll never see money back from it. Instead, make some small cosmetic updates on a kitchen that’s in decent shape. For example, if your existing appliances are in good working order, coat them with electrostatic paint to give them a metallic or enamel-type finish. And you don’t have to rip out your cabinets, either.

Modifying a Bathroom: Bathroom upgrades, like updated countertops and new fixtures, provide solid returns―anywhere from 68 to 78 percent. But, avoid anything trendy. Choose classic features, like off-white tiles. Don’t splurge on all new features. Instead, quick touch-ups on existing sinks, toilets, and tubs are just fine.
Landscaping: The front of your house is the first thing people see, so it makes sense that any improvements—including buying a few trays of flowers. Don’t be afraid to spend money on perennials, which come back year after year.
Installing Central Air-Conditioning: Adding central air to an average house costs thousands of dollars; however, it will also boots your home’s value by 10-20%.
Fixing up the Basement: A dry basement is far more important than worrying about the right lighting or furnishings. If your basement is prone to flooding, leaks, or excess moisture, call in a pro. Basement remodels gain back anywhere from 50 to 100 percent, depending on the quality of the materials.
