Stockton is block by block so anything south of hwy 4 is typically bad. 

From everything I read, I understand that it would be accessible through there.

In my defense, it's a cinder block house, cinder block walls, and it's boarded up now, so it's a legit prison scenario!

@Taylor Chiu it’s across the street from that property same block literally kitty corner and that house hasn’t been updated.

Maybe starting with a property close to you is a good building block...

This is something a property manager will have access to along with accounting software for managing the tenants.

You could also add in that you will be allowed access for showings, for example, each Saturday from 1-3PM, beginning July X, whenever you return from your vacation, but if you're doing repairs after they leave, anyway, I'd usually just let them go without disturbing them, especially if they have pets, then put a sign in the yard while I'm working on it.    

Many of the good PM's will run monthly cash flow reports or give you access to their Property Management software. 

These have good access to Ferry to SF and BART stations.Are these good investments long term (10 years ) ? 

@Allison MeggisonI would strongly suggest working with a local real estate agent, as they will have access to a great deal of information that will be of use to you (comps, previous sales, rental rates in the area, etc.) when it comes to apartments.
