Mostly people with minimal RE experience are adding a single ADU and they often make that choice based on cash flow without taking into account the negative equity position.  

If you added in the cash you should have to protect against contingencies, the actual return goes down (or the risk sykrockets, your choice)- If the $300K properties cashflow, definitely a better bet. 

Otherwise you’re saying you expect other people to subsidize bad choices over and over again.

Yes they can use a realtor of their choice.

Artwork is often personal choice, but you definitely need some stuff there.

Cities like Memphis and Columbus often have more affordable properties and good cash flow opportunities, making them popular choices for investors.

Zillow's closest competitor Realtor.com is another choice to drum up some business.

But if I had a lot more liquid capital and had the choice, I would buy newer ones.

But, all payments with Baselane goes via Stripe gateway, and they apparently have no choice but to honor those requests due to their agreement with Stripe.

You have a few choices, right.
