(If curious, my residential real estate investor clients from 10 years ago [you can find my 10 year old bigger pockets dot com posts :], at the time buying up 2-4 unit properties, a lot of them are now done with the 'human' tenants and want to 1031 into something that is ACTUALLY passive, so yes Starbucks comes up, thus I watch it).In my case I zoomed all the way into a specific brand (which then allows me to make very sweeping generalizations across an entire state -- but still not the entire country), I'm not suggesting you do that, but SOME of the variables need to be narrowed down, before you can gain any useful insights.
