Personally, I love REITs. A lot of people just see them as a stock, but they're really not. Yes, most of them are traded publicly so the prices fluctuate with the market, but they're still backed by the hard assets and a lot of them pay out some great dividends.
Purchasing your own properties is still a better potential investment in most cases. Unless you don't want to hunt down the deals, do the due diligence, and manage the properties. REITs own some of the greatest pieces of real estate in the world, they're managed by the most qualified asset managers out there, and they have the best tenants.
I think investing in REITs and real estate can go hand-in-hand, though. You can stick income from a rental property into your REIT portfolio to earn passive dividend income while you're saving up for your next down payment. They're liquid, so you can cash them out in a matter of minutes. You just have to be aware of the risk that the prices could drop...
REITs are also a great way for somebody that doesn't have enough cash to buy a property to start investing. My favorite REIT right now is about $30/ share, and there are some others with great upside potential for less. Somebody that only has $100 available to invest can buy a few shares, and transfer whatever extra money they have each week into their brokerage account to build their portfolio. Most of my REITs are paying me a 7% - 10% yield because I bought them at the right price, and the payouts have been increasing. So you might as well build up a portfolio of cash flowing REITs while taking advantage of the knowledge you gain in real estate while you're researching which ones to buy.
Real estate people have an upper hand over stock investors when it comes to REITs. While a stock investor or analyst is focused on the number, the real estate investor can look at the properties the REIT owns, the markets they're in, and have better insight into what the future of that portfolio looks like. There are REITs that investors are running from that I'm snagging up for a great price, and I'm extremely confident that they're going to pay off. On the other hand, there are others that investors are loving that I won't touch.
There's a lot that goes into picking the right REITs, though. Even with a strong portfolio, you want to look closely at the balance sheet, particularly the debt/EBITDA ratio (a good rule of thumb is a ratio of 6.0x or less), the debt maturity schedule, the weighted average lease term, and the FFO payout ratio. The FFO payout ratio will tell you how much of their Funds From Operations they're paying in dividends. If it's above 90% there's a good chance they won't be able to maintain their dividends. I like to see less than 85%, but a lot of other investors like to see less than 80%.
It's not enough to just see that they're in a strong financial position, though. You also want to make sure you're getting a good deal. Just because a REIT is priced at $60/ share doesn't mean it's worth that.
