Assuming that SFH remain the standard. Even with ADUs, that changes. (Idea: subsidize only based on the presence of multifamily on a lot?)

Hm. Knock-on effect. That homeowner now has to command the income to pay for the loan. That changes his job choice, consumption habits. Maybe his boss feels that he has to pay him more to keep him happy (and not another worker). If he has to sell, price has to be higher in order to break even/get a return. Solar is probably a good thing for municipal expenses, re: less strain on the power grid, but you also get a better turn in that regard converting multi-family or non-residential buildings.
