While many environmentally-conscious or "green" updates such as solar panels, wind turbines and geothermal pumps are far too costly for the owner to realize any return on investment, some low-cost items can make a home more desirable. Â In most cases, the value prospect is that the updates show the owners attention to caring for the property. Â The owners proactive attitude toward the property will make many buyers see the home as more valuable. Â If the buyers see more value in the home, they will be more likely to put in a higher offer. Â Although buyers really don't consider most home updates as "green updates" they really should. Â Even a traditional-style large-tank hot water heater is much more energy efficient than models made 15 years ago. Â Any small improvement in energy efficiency adds up over time. Â So the lower up-front cost items like hot water heaters will provide a faster return on investment than something like a solar cell array.
