Statistical argument for 401k vs REI

[Chris Walter]

Hey BP! First time post - super excited to be a part of the community here!

I've given a first effort of searching for forums, but partly may be using poor keywords for my search and/or I may have been overwhelmed by the number of results that showed up - so asking for a breadcrumb.

Does anyone know if there has been a forum post, or blog article written, looking at the long-term returns of 401k investment vs. REI? Specifically, a rundown of sustained contributions to a 401k, its growth, and what post-retirement distributions look like, vs the long term value of cash flowing rentals (cash flow over the years, mortgage paydown, and assumed appreciation).

It's something that I have been thinking a lot about, and am ready to put the work into creating theoretical scenarios, but figured if the work has already been done, I'd love to save myself the time :)
