By that time I retire, I need to either pay off my primary home or rentals whichever is tax efficient at that time. 

Whats nice is that there are NO balconies so people arent outside on the balcony talking loudly on their cell phones.

Remember, whichever new tenant you put in will be locked in under rent control as well at the new rate, so in 5-10 years that rate will be relatively low as well.

I ended my contract with AT&T cell phone and internet and uverse.

I have an 11.37% Cap rate, and a 24% ROI and a solid 1.77 towards the 1% or 2% rule for whichever you follow.  

I can't negotiate with the cell phone co.

I'm young in the game, my mentor Christopher does it all; flipping, rentals, private/hardmoney lending (whichever distinction you choose to draw from those two i suppose).  

Choose which ever works best for you.

Here in WV the Landlord has to notify tenant within 30 or 60 days (which ever the lease states) How much of the deposit is being returned and an itemized list of what was deducted from it.You should have saved yourself $600.
