Some great points. Since these REITs are large companies, I'm guessing that they have staff, and won't be paying the same commissions you or I would pay, but you're definitely right they wouldn't get the total appreciation as a net.
I also suspect their model is not pure appreciation, since with anything less than 25% vacancy should cash flow for them. In the sample I provided above with the 11 properties, they were cash-flowing at about $3k/yr each with a still pretty high 15% vacancy rate. Since AH4R is a publicly-traded company (AHR), we can look into their books. They claim that their Operating Margin is 21.2% which is the amount of cash left over after paying expenses on every dollar earned. How much of that comes from appreciation or cash-flow is a mystery without reading their full-reports--a task I'd rather not perform.
I'd further assume that if interest rates are still reasonable, and the math dictates it's still profitable, that they will just roll over the loans on these properties rather than sell them. That, or sell off a percentage as homes age past whatever their model dictates, and reinvest in newer homes to rebalance the portfolio.
Lastly, even if they only make appreciation of $15k/property, that means a company like AH4R will net $750 million since their portfolio is 50,000 properties. Probably not the return shareholders are hoping for, since that's only about a $3/share return, which is a pretty paltry 15% over a 10-year holding period, based on current stock price of about $20/share--so if there was no operating income, this wouldn't be a great stock investment.
There is definitely some risk baked into their model, which is why they have to pay bondholders a better rate of return than they would get investing in a Treasury Note where your principal is guaranteed by the US Government, or putting the money into CDs where it is guaranteed by FDIC.
