I can’t imagine an ADU would be very beneficial, and most dont have a basement to convert into more bed/baths.

Renting for all my independent life now, I've noticed rentals I've found were on certain platforms being advertised, like craigslist, apartments.com, Facebook marketplace, and landlords posting to their personal social media accounts.However, I can't imagine these avenues being the only advertising methods, when you have something like vacancy to fill.

Just imagine if you had a property manager charging that much on a 400k house - that would be nearly $350 per month!

As you can imagine capital starts drying up quickly "trapping" 20% into each unit.

I couldn't have imagined it just a few years ago.

I can't imagine someone arguing with this (but I'm sure there will be someone).

Just like wealth, knowledge compounds overtime to something much larger than you ever imagined it could be.

But, if they are flippers/rehabbers, investors, property managers, I could see that being a benefit.And I would certainly be looking at flight options into either market, as I couldn't imagine putting hundreds of thousands of dollars into investments in a market with visiting those investments at least a couple times per year.  

I also know that they "didn't know about the sale ahead of time", so I have to imagine that played a role in the lien. 

I'd imagine having a roommate who also gains equity would turn into a legal nightmare when either of us decide to move.
