Are capitalization rate and net profit margin the same thing?
Both of these terms do refer to your profit; they're just different ways of evaluating it. First, your definition of capitalization rate is flipped.  As explained here, it should be: On the other hand, as explained here: So cap rate is like a reverse unit cost approach to comparing two investments.  If house A costs $1M and you'll make $50K (profit) from it yearly, and house B costs $1.33M and you'll make $65K (profit) from it yearly, then you can compute cap rates to see that A is a more efficient investment from the point of view of income vs. amount-of-money-you-have-stuck-in-this-investment-and-unavailable-for-use-elsewhere. Profit margin, on the other hand, cares more about your ongoing expenses than about your total investment.  If it costs less to maintain property B than it does to maintain property A, then you could have something like: So B is a more efficient investment from the point of view of the fraction of your revenue you actually get to keep each year. Certainly you could think of the property's value as an opportunity cost and factor that into the net profit margin equation to get a more robust estimate of exactly how efficient your investment is.  You can keep piling more factors into the equation until you've accounted for every possible facet of your investment.  This is what accountants and economists spend their days doing. :-)
