Stephen, yes, let me try to hit each of those. So, you know, I think we've been talking about the markets where we've seen kind of the in - the rate of pace on year-over-year and quarter-over-quarter increases moved a level that I think we've been uncomfortable with. And I would tell you that's primarily Southern Cal, the Bay, Dallas. You know, Dallas - I mean, Denver interestingly enough has also had a very significant pace on price appreciation but we haven't seen the same consumer reaction in Denver as we have in what I would say are the California markets. And Dallas, we've been talking about that now for, gosh, probably two years Stephen. When I think about incentives, you look at a market like even an affordable community in Southern California where maybe a year ago the price was a half million dollars, today when you take the combination of that price appreciation, 6%, 7%, 8% in 12 months, and the change of interest rates, it is sticker shock for the consumer. I mean, that mortgage payment, with all things - all other things being equal could be up 20% to 25%. So what we're really doing with the incentive is obviously as we started to really feel the pace of mortgage interest rates moving. We made a, I think, strategic decision at the field level to make sure we align our incentives with the specific needs of the buyer. And if you can imagine, they're all very different. Some need help in closing costs, some need help with a lower rate, we'll use it for a buy down some, maybe an extended lock. So it's a little bit different but we have is the flexibility within those communities to work with the individual customer needs. As I look forward, I think we need to see, I mean, we'll continue to use the incentive dollars when you just want to talk about the sales floor incentive, I think more importantly it's really making sure that we use the time to help our customers understand what they have. You know, we prequalify our buyers, obviously before we get them into contract and that's been really important for us, but I think in today's environment it's so easy just to jump to interest rate. And what we really have to do is make sure our sales team and our loan consultants are properly trained to talk to the customer; the natural tendency is just to go right to rates. But, like I said in my prepared comments, the real issue is payment. So we need to walk them through the numbers. Don't lead with the interest rate, help them understand what they can afford because, like I said, on average they have somewhere between 300 and 500 basis points of room before they're priced out.
