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

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

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 .

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.

@Salome Ditmars there are many out there—but unfortunately there is no centralized repository to locate them.

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?

If you do not have those it will extremely hard to ever sell it to someone who will require bank/lender financing or refinance it down the road if you want to pull out cash on the ARV or future equity.The other rule of thumb is that you buy it New and that it was never on another property or location, simple built onsite or trailered in from warehouse. 

.: @Gash Nookala - if your property is not in the Hampton Cove area of Owens Cross Roads, you honestly are not in an ideal location for a rental.
