I live in a middle class neighborhood in the south part of the county. I'm about a mile and half from Biscayne Bay as the crow flies, but have no view unless I happen to be on the roof and even then, binoculars help a lot. Most of the houses in my area were built in the 1950s. In other words, its an established neighborhood on the "right" side of US 1 (US 1 is kind of a boundary in the south part of Miami; east of it, where I am, is much more desirable).<BR/><BR/>From 1992 to 2000 the value of my home rose modestly, say roughly 10-15% for the entire time. From 2000 to the peak (2006) the value quadrupled. The price has now fallen, but from 2000 I'm still sitting on at least a double and more likely a triple. <BR/><BR/>Neither CS or OFHEO comes anywhere close to approximating my experience. And I guess that is the point; real estate is always local. National indices will never capture what is really going on. <BR/><BR/>Personally, I think the housing bubble, as a national phenomenon, was vastly over rated. Most of the activity was concentrated in the sand states and that is where most of the foreclosures are concentrated. Having lived through the 80s in CA and Florida now, I've had a front row seat for volatile home prices. It just seems fairly normal to me.Boomerhttps://www.blogger.com/profile/12580333039230290448noreply@blogger.comtag:blogger.com,1999:blog-7539577136486286096.post-7024330194982203332009-04-01T13:47:00.000-05:002009-04-01T13:47:00.000-05:00Firstly, when the Wall Street securitization machi...Firstly, when the Wall Street securitization machine of residential mortgage backed securities went into high gear between 2004-2007, and secondly, when Fannie & Freddie were under strict regulatory scrutiny due to the accounting scandals, Frannie's market share of originations (re-fis and sales) dropped to 35%.<BR/><BR/>Assuming that originations were equally re-fi and sales, the Frannie data only captured about 20% of national sales for FHFA purposes. <BR/><BR/>Why would anyone (including Alan <I>local froth</I> Greenspan) rely on such suspect, spurious data is a conundrum.

So you are. Curious.<BR/><BR/>The difference in the OFHEO data and CS must be almost entirely explainable by the selection bias between Freddie/Fannie conforming loan requirements that create a massive selection bias in the OFHEO samples, zeroing out the impact of every non-conforming mortgage origination, which came to dominate the market after 2003.buermannhttps://www.blogger.com/profile/14876839557540319179noreply@blogger.comtag:blogger.com,1999:blog-7539577136486286096.post-30890930961446701222009-03-31T14:28:00.000-05:002009-03-31T14:28:00.000-05:00If as CS speculates, house prices doubled relative...If as CS speculates, house prices doubled relative to construction costs, would not vacant landowners who sold for residential development capture most of this excess gain? If not, then possibly there is an underestimation of the costs to make necessary lot upgrades to make the land capable of supporting a house structure and of the costs to acquire the necessary regulatory approvals. Over time, in regions with limited development potential with an undersupply of homes, either due to regulatory or topographical factors, the marginal cost of buildable land should rise.<BR/><BR/>Are there any indices of regional or national vacant land prices so regional growth rates in land prices versus home prices can be compared?Milton Rechthttps://www.blogger.com/profile/02488660316957122768noreply@blogger.comtag:blogger.com,1999:blog-7539577136486286096.post-90653632826680289672009-03-31T13:31:00.000-05:002009-03-31T13:31:00.000-05:00CaseyI´m willing to take a shot!

Since the C-S index is heavily weighed with California prices, that should explain a good fraction of the difference with the OFHEO.João Marcushttps://www.blogger.com/profile/13658264244033012660noreply@blogger.com
