Depending on if you'd like to flip houses or grow a buy & hold empire will determine which is better.

A number of empirical studies have shown post market knowledge is very weak, a broken process. 

Owner occupancy and parking requirements were dropped for ADU's last year, which is a huge opportunity for you to leap-frog your single family house-hacks into a rental empire (this is what we're doing)Unfortunately almost nothing turnkey will cashflow here - which makes sense.

I am not trying to build an empire.
