Interesting article with a few stats about the magnitude of real estate speculation in some markets: Mortgage lenders warn about speculators in the market Nationâs Housing KENNETH R. HARNEY WASHINGTON-- One of the key players in the home mortgage market quietly signaled this year that it believes real estate speculation in some parts of the country is approaching worrisome levels. PMI Mortgage Insurance Co. told its network of lenders in March that it would no longer insure new loans made to borrowers who already have more than four mortgages outstanding or who represent more than $350,000 worth of "risk exposure" to the company. A second large underwriter, MGIC Mortgage Insurance Corp., confirmed that it, too, is carefully monitoring real estate speculation in hot housing markets, and has serious concerns about certain interest-only mortgages that investors are using to buy multiple houses or condos. Both companiesâ comments came in the wake of a study that found that nearly one house out of four purchased in the United States during 2004 Was bought for investment, not for owner occupancy. Another 13 percent of all purchases were vacation homes, according to the National Association of Realtors. Mortgage insurers, who underwrite loans with low down payments, are highly vulnerable to defaults by speculators who find themselves with negative cash flows on multiple houses. Mortgage insurers generally cover the first 25 percent of a lender's losses on a home loan that goes belly-up, but in some cases they cover even more. "Weâre seeing an increase in investor loans," said PMI spokeswoman Beth Haiken, "so from a risk management standpoint" the company decided to tighten its guidelines for borrowers with home loan debt on multiple properties or who present high potential loss exposure. MGICs vice president for credit policy, David Greco, said "we are watching a number of markets closely" for signs of excess speculation, such as individual investors buying houses or condos solely to hold for short periods, then flip for quick profits. The problem, say insurers and others in the mortgage industry, is that when property appreciation rates decline in the hottest markets, speculators are likely to be stuck with properties they canât sell at the prices they need. Negative cash flows are then likely to push them into default. Anecdotal evidence has mounted for a year or more that speculation is helping push prices higher in southern California, Las Vegas and Reno, Nev., Miami and metropolitan Washington, D.C. All those areas racked up substantial double-digit home-price gains in 2004, but also showed signs of significant cooling in the final quarter of the year. For instance, Las Vegas saw a heady 36.2 percent average gain in home prices during the past calendar year. Yet prices in the fourth quarter gained just 6.7 percent on an annualized basis, according to a new survey by the Office of Federal Housing Enterprise Oversight. In San Diego, prices in the fourth quarter jumped by an annualized 8.96 percent versus a 24.4 percent rate for the year as a whole. In metropolitan Washington, annualized price gains slowed to 9.8 percent from 21 percent. PMFs Haiken said certain r types of mortgage financing plans commonly used by investors can worsen the problem. Interest-only adjustable-rate mortgages with two- and three-year initial periods of low monthly payments followed by sharply increased costs can force investors to sell on disadvantageous terms, when appreciation rates are on the decline. "We are approaching interest-only loans very carefully," said Haiken, particularly when these are the types of mortgages small- scale investors are using to buy multiple houses or condos for speculation in hot markets that may have hit their cyclical peaks. Haiken's firm has identified a handful of high-froth metropolitan areas that have the greatest likelihood of home value declines over the next 24 months. The PMI Risk Index looks at median household incomes, median mortgage payments, employment changes and home affordability. Tops on the list are Boston and San Jose, Calif., both of which have better than a 50 percent chance of seeing home price reversals in the next two years, according to PMI, followed by San Francisco (48 percent chance), Providence, R.I. (40 percent), metropolitan New York and Los Angeles (36 percent). Metropolitan Washington D.C. is rated an "average" risk by PMI, with just a 15 percent chance of property value declines during the coming 24 months The takeaway here: Before you start playing Monopoly with real houses and condos, give serious thought about whether you might be buying into the top end of the current boom, and may not reap the big, quick gains you want or need.
