Can a REIT be evaluated using the same metrics as regular stocks? Perhaps no and if so are there any REIT specific tools?
E.g. These symbols "O", "DLR" are considered overvalued by regular metrics.
REIT's are a different beast than your normal corporate stock (such as $AAPL). Here is a good article to get you started. From there you can do some more research into what you think you will need to truly evaluate an REIT.
When evaluating REITs, you will get a clearer picture by looking at funds from operations (FFO) rather than looking at net income. If you are seriously considering the investment, try to calculate adjusted funds from operations (AFFO), which deducts the likely expenditures necessary to maintain the real estate portfolio. AFFO is also a good measure of the REIT's dividend-paying capacity. Finally, the ratio price-to-AFFO and the AFFO yield (AFFO/price) are tools for analyzing an REIT: look for a reasonable multiple combined with good prospects for growth in the underlying AFFO.
