Yeah. It's a really interesting question and you can imagine, Alan, we've dissected this pretty good. So, I'll start by saying kind of when I look at the rate in the fourth quarter, it's -- the absolute coupon rate that we close people at, it's probably the lowest we've seen in over a year. And I think that's just a kind of a point of time when we saw where rates were kind of late summer, early fall, where we're using and sorry to be redundant, but where we're really using and where we're seeing the most competitive pressure would be within our first-time buyer communities. There is not -- I mean unfortunately with those consumers it is very, very black and white that what they need to do to be able to qualify. Our pre-quals are more challenged. They're very, very patient or payment conscious. Their ratios are a little bit more difficult. But the numbers of that first-time buyer, they're still very large. It's a very large penetration, because they're trying to get out of what I would say are higher rents today. One of the examples I'll share that I think helps you understand really the benefit we're seeing with our consumers. That program that I mentioned, Alan, our Buy Build Secure flex program, instead of having to just discount the house or do a very expensive forward commitment where we're assisting a consumer, guaranteeing that they're going to have a 1% reduction to the market rate. Let's say on an average -- let me take a $500,000 house with a 20% down payment, a 400,000 loan, to do that it's costing me, let's say approximately $16,000. To get that consumer to the same monthly payment, it would cost me $60,000 to $65,000 price adjustment. So, when I can use these tools most efficiently to help that consumer and I'm using $16,000 as compared to what -- we're seeing things in the market today that are 299, 399, those can cost 700, 800, 900 basis points. We're doing some of these programs at a fraction, and we're not taking it off the price, which is also protecting our margin. But there's not just kind of one special pill here. It's very personalized to the consumer. But because we're not spreading these forward commitments across the portfolio and it is a much smaller, I think than probably what the industry is recognizing, it's really helping retain our margin strength.
