The only place that is not reflected is in the appraisals .... and I am trying to understand why.
Even according to Randolphs numbers of the community in SD in the report I provided with and without Solar the solar homes sold for more .... not the 17% the headline wanted to indicate .... but still more. Yet no one here is willing to say that they would increase the amount of their appraisal because of Solar even a little. I just don't see why.
Spartacus, my bold.
You do not understand how buyers operate in the housing market. You do not understand the report that was written and the flaws in the statistics. You don't see a problem with grouping homes into homes with solar panels and homes that do not have solar panels and then attributing a cause and effect that solar panels are responsible for the total price difference between the two groups. That is what the report did and to make matters worse, it did it over several years in a rapidly rising price market. (Prices of the homes in the SheaHomes communities ranged from $437,900 to $840,938. The mean price was $601,984.)
The primary variable that drives the home's value is the GLA. Larger homes sell for more however, they sell for less in a price per square foot bais.
Look at this page in the report. Maybe you will understand.
There are other variables at play that are not isolated. Looking at the 2006 data from the MLS, 5 homes sold with solar panels for a median sold price of $1,130,000. 3 of the 5 homes had swimming pools and ranged from $1,130,000 to $1,395,000 sold price and had GLA sizes of 3,215 to 3,638 square feet GLA.
The 2 homes that sold with out swimming pools ranged from $997,000 to 1,050,000 with GLA size of 2,612 to 3,188 square feet GLA.
Clearly GLA size and swimming pools matter in either case of homes with solar panels. That same correlation shows up in homes with out solar panels.
There are other factors that were not isolated that make more of a difference than solar panels such as location (view) and quality of upgrades.
Let me make a point to you about buyers of million dollar homes.
If you have to ask how much are you utility bills, you can't afford the home. That does not enter into the buyer's mind when shopping for a home.
Just for reference, the property taxes on a sale of a million dollar home will be $10,000 a year not county other assessments. Anybody who thinks about utility bills ought to think about property taxes since they will be paying much more every year than their utility bill.
