Some of the criteria I consider are:-Items of value have been removed-Utilities are disconnected-Neighbors have not seen activity at the house for several days-No return communication or communication that they have leftAgain, there is no need to go through the eviction process if they are gone

Great student population to rent to.Tracy is also a good location since there are alot of commuters to job locations in the east bay.Byron is a sleepy farm town. not good for investment.Sacramento is one of the best markets in the nation as you mentioned.Given all this, I would disconnect your passion with your investment criteria. 

Also, when I reread your post I think there’s a disconnect on your payments.
