The year's best-performing
real estate investment trusts , or REITs, have been those with holdings in lodgings and resorts, up nearly 36%. Industrial real estate REITs are up more than 32%. Apartment complex REITs are up some 26%. I found this out not from some press release but on the Web site of the National Association of Real Estate Investment Trusts, where aggregate performance stats are refreshed monthly. (The ones I cite are from Sept. 30.) As you'll see, it's one of a handful of spots on the Web where you can comparison-shop and perform due diligence on REITs. For the uninitiated, REITs are asset-management companies that own real estate -- everything from trailer parks to prime downtown office buildings to state prisons. Another species of REITs holds mortgage debt. For tax purposes, REITs are organized a little like limited partnerships. Instead of paying taxes on their profits, they pass them along to shareholders in the form of dividends. However, unlike limited partnerships, REITs trade just like stocks. REITs fared poorly during the recent tech-stock boom. In 1999, for example, the average REIT returned a negative 6.48%, according to NAREIT. Back then, investors scoffed at the 7% to 10% annual yields. After all, you could buy an Internet stock in the morning and make 33% on it by noon. But, alas, the world has changed. This year, REITs have outperformed the major indices, returning more than 21%, on average, through Sept. 30. No surprise that in this bear market, REITs have garnered lots of attention. Last month, for example, TSC chief markets columnist Brett D. Fromson wrote favorably about Annaly Mortgage Management ( NLY), a mortgage REIT yielding close to 15% as of midweek. But some analysts worry REITs may become overbought. That was the fear TSC Contributing Editor Christopher Edmonds relayed in his column earlier this month. That issue also came up in a REITs roundtable discussion , which Edmonds reported on this week. One fear is that momentum investors searching for a safe place to stash cash until tech stocks bottom will park their money in REITs and drive up prices. That's a little like what occurred in 1996. Back then, yields averaged around 6% and total returns topped 30%. As a result, REITs became a magnet for growth investors. Knowing they needed to grow their companies to meet shareholder expectations, REIT managers turned to the equity markets for capital -- a big mistake, as it turned out, says Ralph L. Block, author of Investing in REITs (Bloomberg). "A lot of REITs issued too much equity in '97-'98," says Block. Some REITs issued so many new shares in the spring of '98, he says, they grew their market cap by more than 40%. Fearing further dilution, investors took flight. And share prices plummeted. Could the same thing happen again? Who knows? But it always pays to shop around. At last count there were 195 REITs to choose from, as well as dozens of mutual funds focusing on the sector. Betting on an individual REIT demands considerable judgment on your part. The following examples are not meant as recommendations, but rather to illustrate some of the choices you'll face. REITs that invest in mobile-home parks, such as Sun Communities ( SUI), aren't very glamorous, but they're consistent cash producers. That's because once folks park their homes on sites, they tend to stay put, even if rents rise. By the same token, if you invest in a prison-owning REIT such as Correctional Properties ( CPV), you can be pretty sure the tenants won't up and leave. Still other investors prefer REITs like Boston Properties ( BXP) or Vornado Realty Trust ( VNO). Both focus their holdings in specific regions. Theoretically, REITS like these should be able to consolidate their services and leverage their local knowledge. Once you've settled on one or more categories of REITs, you need to understand how Wall Street evaluates them -- and how it doesn't. Breakup value doesn't work because REITs' main assets -- the buildings themselves -- can take years to sell. Some analysts prefer net asset value , which factors in the value of a REIT's management team, along with bricks-and-mortar assets, then subtracts liabilities and obligations. But as a measure, net asset value may not take into account such things as when each building was appraised or how much it may have increased or declined in value since the appraisal. Most analysts gauge a REIT's health using something called funds from operations , or FFO. To calculate FFO, start with net income. Subtract out any extraordinary gains, like proceeds from the sale of a property. Then add in real estate depreciation. REITs are often valued at 14 to 15 times projected FFOs, for the 12 months going forward. You also have variations on FFO, such as adjusted funds from operations (AFFO), which take into account mandatory improvements to the properties that won't necessarily enhance their value -- things like new carpet in the hallways. Don't expect to see an FFO figure come up when you enter a REIT ticker symbol at a financial Web site. If you really want to deconstruct a REIT issue, you'll need to visit a site dedicated to REITs.
