I am a new graduate from California State University, Sacramento with a bachelors in psychology.

I have degrees in education and psychology. 

Psychologically I think this is tougher play. 

(That was an attempt at Psychology 101).

I have a Masters Degree in Psychology which gives me great insight into the motivations of the person on the other side of the negotiating table

These types of things are psychological and matters of local knowledge and that's kind of hard to program into an algorithym.In the long run, real estate investing is very forgiving of mistakes you make as you learn.  

I have seen some that have CPI based bump every couple of years.Is there psychological about 3% every 3 rather 1%/yr?

However recognising that some landlords have terrible business practices and struggle psychologically with the responsibility of efficient tenant turn over it is conceivable they see a benefit in paying a portion of their tenants rent.  

Attended college in Michigan majoring in Networking/ IT Security then switching to Psychology.

Mathematically, it seems to make sense to just say $1,000/mo "take it or leave it", but I'm just trying to see if there's a strategy that allows me to have 0% vacancy by keeping 10-year+ tenants.I think that anybody facing a $300/mo rent increase psychologically would just say "I'm out of here," whereas a $100/mo rent increase, I'm pretty sure they can get on board with.
