Oakland Rent Control increases

[Daniel Antonetti]

I have a tenant that moved in June 15, 2016, and I would like to increase his rent as of July 1, 2017

The CPI starting July 1, 2016 was 2%

But the new Oakland CPI comes out in July 1, 2017.

So 

1) Can I increase his rent on July 1, 2017 by 2% even though at that point it will be the previous year's CPI?

2) Do I have to wait until I see the CPI for 2017 to know how much I can raise it? And then wait until September 1, 2017 to raise it?

3) At that point can I use the 2% from 2016 as a banked increase and increase it by 4% (Assuming 2017 is 2% also)?
