Sure. So yes, just a few comments on the margins. So when you look at the company, scale helps a lot. Not only on leveraging some of the fixed costs that are included in margin but particularly on the supplier side, materials, labor, et cetera, in the market. So that's why there's such a focus within the company, within the company's divisions on achieving a large scale in each of our served markets. So that's been a very favorable factor for the company. Number two, as you know, Mike, we've done a tremendous amount of work on our capital structure over the years and particularly back to the period that you mentioned, our interest amortization is way down compared to prior, and that's a direct improvement in margin. That just went right to the margin line, and that is very sustainable and in fact, some future potential there as well as our inventory balance continues to grow, our debt levels stay either constant or slightly decreasing, and we have a really nice capital structure now. And now with our new Ba1 status with Moody's and the recent upgrade that we also received, we're in really good shape on the capital side of things and the interest side of things, so that's good. So as far as sustainability goes, if you look at 21% low-20s, let's call it, margins, I think they're very sustainable and in fact, things that we can build upon as we achieve higher levels of scale in our served market as we grow the total company topline. And as we move forward with some of our supplier and cost strategies, I certainly think margins are sustainable and could even expand from here. So we'll see as we go. I think the single largest tailwind that we could experience is just reduction of incentives. As you know, we're not really an incentive-based company. We've been playing that game for a while in the face of these higher interest rates in order to generate affordability for our buyers. But us along with most people don't think these rates are here to stay for the long-term. And although they may not reach the low levels that they once were at, there's a fairly sizable margin pickup that could be gained just from seeing that go away. So those are the – I guess, my high-level thoughts on that margin question. As far as option lot strategy, we're not seeing much change internally from a margin point of view on that side of things. We'll take the option lots if they're out there and available. If they're not, we're pretty focused on just expanding community count and developing our own lots as we go. So we'll see how that shakes out. But overall, pretty pleased with margins. Very pleased with the expansion and the sustained higher level that we've been experiencing in the last few years. And hopefully, we can build upon those in the future.
