That's the only reaction you can have to Stuart Miller's comments about the spike in mortgage rates, at least when it comes to the business of Lennar ( LEN), one of the nation's largest homebuilders. Miller's quarter, a strong one by any stretch of the imagination, was, to me, the test I have been waiting for. It's a gauge of what has happened in this incredibly important industry after the 10-year Treasury yield almost doubled and mortgage rates went from roughly 3.5% to 4.85% in a matter of months. This is the first quarter that really encompasses that rise. Some of the company's sales were no doubt saved by mortgage lock-ins, the period defined by August -- but a glimpse of September that Stuart offered "Mad Money" viewers shows that it was, indeed, no more than a speed bump along a road to a very strong housing recovery. June, the first month of the rate impact rise, was very strong for this national homebuilder. July, however, seems like it was the exact opposite. Yet it came roaring back in August, and it looks like, between the lines, that September remained strong. What could explain this conundrum? The cost of a product is going up substantially, and yet sales do not get hurt that badly and orders still go higher, although not as high as some analysts expected. Miller says everything hinges on the production deficit and easier credit year over year. In other words, the U.S. is building far fewer residences than we needed -- between 900,000 and 950,000 -- and we can't possibly make up for the "production deficit" that the downturn has caused. Many believe the overbuilding hangover of the mid-2000s is still with us. That's not apparently the case any longer, Miller said. Plus, there's the difficulty of building new units, because of a shortage of entitled land and the dearth of smaller homebuilders, who could not survive the downturn. This makes it so there's much more room to build homes than what people had recognized. We know that Lennar's 18,250 to 18,500 prospective units are far fewer than what's needed. Otherwise, gross margins wouldn't be on the rise, despite the hefty increases in labor, moderated by a declining price of the key ingredient of lumber.
So we have more affordability of credit -- something confirmed by Richard Smith, CEO of Realogy ( RLGY), the nation's largest real estate broker -- and a slightly higher price of homes year over year, as well as interest rates still at historically acceptable levels. That combination means the housing industry remains on a growth track. I think that strength's not in Lennar's stock or in the zeitgeist of the investing public, which remains convinced of the long-lasting damage that the rate increase is causing. Lennar, and to some extent KB Home ( KBH), have shown this: Unless rates go up again, business will be just fine. They show that, after a gigantic pause when the homebuilders bided their time, they are now ready to advance, even if rates go back to where they were a couple of weeks ago. Lennar in particular has an excellent perspective on things, because it is also a huge builder of apartments and it provides housing financing. There simply is no reason to believe that Miller's view can be questioned. I didn't feel that way after the previous quarter, because I was worried about the rate increases coming, as a tapering from the Fed seemed to be in the cards. Now that the market has boosted rates already, it looks to have been digestible -- certainly more digestible then the common wisdom holds. That means this group, and all of its accoutrements, can be owned again. July was aberrant, for certain, but the rates haven't defeated the home buyers. Meanwhile, the lack of supply should allow the home resurgence to last far longer than people expect. That's particularly so for those who believe there are now bubbles all over the place and prospective homebuyers have been defeated by the higher rates now prevailing across the country. The Lennar release, the conference call and the interview, I thought, made for an irrefutable thesis. The industry can be "go-to" once again after a prolonged period in the wilderness.
