That brings up an interesting point about net lease assets: Growth comes largely via portfolio expansion (contractual rent increases are nice, but generally track along with inflation). Because of the scale of a mall, and the fact that being in wealthy and well populated regions is vital, it can't just add assets willy nilly -- each property must be capable of standing on its own. The sky isn't falling Realty Income's portfolio has held up very well (its occupancy is over 98%) despite the increasing pain being felt in the retail sector as consumers shift toward online shopping.
