We'll get there next year, but to take the price leap, we have some new tech to get ready for market.
CA has Title 24, which mandates net zero for new homes, so that is the long term focus.
Check out the home we just completed for $145K, looks great, great performance and very comfortable. It's just hard to do at scale with out a bit of a war chest.
As you know, blowing foam, sealing leaks, upgrading HVAC, and good windows will run most folks close to $60-$100k to upgrade. That will still leave it fairly leaky, have an un-insulated foundation and be an older structure. Wish there was an easier solution to upgrading existing homes, but that is a tough business.
