Maybe I'll let Landmark answer that first.
There have been programs over the years for homeowners to buy green homes. I think a percentage of homeowners will buy those homes, but there's not enough supply on the market. I would say that there's probably about 30% who will buy them because they want to buy them. They believe in it. Honestly, I don't think there's enough supply on the market across the country.
You talked about homeowners needing to be incentivized to buy a home like that. For me—and this always comes back to this cost discussion—actually, I don't necessarily believe that a green home is that much more expensive than a normal home, just like a green building is not necessarily more expensive than a conventional building. It depends on how you look at it. There have been many studies where they put down a list of green versus non-green, and the costs were.... It depends on what you want. People spend more on countertops—
