There will likely be significant traffic noise, including big trucks using jake (engine) brakes to slow down. 

Mom and pop tenants tend to just want to be in a good location but national tenants are very picky about the placement in a center and their tenants walk ability and traffic flow. 

If you get a place on a small side street thats not really developed and theres not much foot/car traffic it may feel a little rougher as compared to if you purchase something on a main street such as 20th or Wharton.

I stumbled upon BP's podcast (then the forum) when searching for a way to learn on-the-go in the lovely LA traffic each and everyday, I was hooked when I heard more stories of building wealth the right way.I currently own my house in Huntington, however searching for ways to take my first step in REI, whether that is in CA, where cap rates are low and prices high, or OOS, but very wary of D class neighborhoods. 

More or less all traffic/license related issues.

It is right on a highway that gets a lot of traffic.

I’d also check out Hayward/Castro Valley/Union City areas since they’re nice, relatively cheap, and fine as long as you have no need to cross 92 because it’s a bear for traffic.

Indoor and outdoor safety considerations.Talk with your insurance broker about proper coverage for you and for their business, especially liability.Consider the impact on the neighbors.... noise, traffic, parking.Consider the extra wear and tear and how you would be compensated.You say these tenants are just renting until they have enough in savings to purchase a house of their own.

Certainly all of the items on your list and Alina's list are part of the discussion because income or expenses being out of whack originate from things like occupancy, turnover, traffic, evictions, leasing ratios, etc.3.
