You didn't read here that you have to give a reason....because you don't.
I had a unit a long time back that I wanted to get empty and renovate. Because I didn't have rent control, I was able to raise the rent by $100 each month. It took only 2 months ($200) to get them to move. I had no problem with them hanging on till I had to file for holdover eviction...they were glad to be leaving. (knowning that I was raising the rent by another $100 for the 3rd month in a row was powerful motivation for them to get gone).
