Yea I call bullshit. The actual article is on a rental blog pushing passive income and is just throwing around a bunch of misleading numbers while hand waving violently. This isn't analysis, it's just content farming.
Prepended this with a more informative title. This is an aggregate newsletter which I think is helpful if you're in the property management / real estate business. Hopefully this new title is a bit more informative, apologies for any misleading
