Los Angeles's own numbers show that ADUs are not being built in high rent locations.

Also, from what I’m reading house hacking doesn’t really seem to be scalable since you have to reside in the location?

You don't say where you are located so I say start close to home and work from there. 

Therefore, your financial freedom hinges on new companies continuously moving into the city, creating replacement jobs.Companies have many options when selecting a location to set up operations.

And location makes a huge difference. in Markets that dont move much in value then door count can be critical but in markets where prices may have 2X to 3X over the last say 15 years door counts are not as critical to net worth .

In the long term I expect Miami to outperform CPI because it is a destination location and coastal land is more constrained than inland (such as Midwest, central, etc).  

I do manage these myself through a small STR management company that I own that manages about a dozen locations.

Property is in downtown San Jose location with possibility of new parks next to our location being built and also new constructions around our neighborhood.2.

The house was in a terrible location, at night there was gun shots.

@Adam OrtizRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?
