Depreciation - How to Account for on Income Statement?

[Billy Raz]

Hi,

I'm working on the financials section of my BP.  How do you calculate and include depreciation on the income statements?

If I use a depreciation calculator and calculate an annualized deprecation amount of $3k, should I add this is a month gain...  I'm confused.  

The properties will be SFR with a buy and hold.

Thanks,
