My general answer is yes, that's what we do. We try to make sure that dollars and programming are used effectively and that we're seeing results, and we do that regularly.
I'll maybe turn to Alison if there are specifics on the housing front, but one observation would be that some of these things have long time frames, so it's difficult to know. We were talking earlier about incentives that improve the financing of multi-unit rental construction. It's a multi-year process to put your financing and permitting together, so the exact efficacy of those, the evaluation of their effectiveness, will take a number of years. You can look at things in the middle.
Alison, is there anything specific on the housing side?
