The more upgrades you have in the home, the higher the valuation is likely to be. This being said, you should be aware of the market cap because the price won’t keep rising endlessly. In Phoenix, we can expect between $1.50 and $2.25 to be added to a home’s value per watt installed on the roof of the property. In general terms, experts believe few will go beyond an additional 15% for energy improvements.
In Arizona, we have fairly respectable utility bills which means that energy upgrades don’t have the same impact as they do in other areas. If we use California as an example, their rates are much higher so energy upgrades become more beneficial to new owners; the difference they see in utility bills will be significant. With this in mind, energy improvements have a larger impact on the valuation.
