20. Install a Water Filtration System
Something that few people consider as an addition to the value of their home is the quality of their water supply. “Install a water filtration system in your kitchen. Not only do these systems purify your water, they will also lower your grocery bills — no more bottled water. A water filtration system is an inexpensive addition, but it’s the sort of small luxury that homebuyers love.”

The cost of a water filtration system is going to vary drastically depending on what kind you get installed. For example, a carbon filter system can cost as little as $50, while a reverse osmosis system may cost as much as $4,000. It’s also something that may be missed during home tours if you’re thinking of selling your house. For more of a show-and-tell sort of water filter, consider buying one of those over-the-faucet water filters, which cost under $40. (via HGTV)
