How much in tax deductions should I really take

[Greg Seivert]

I'm reading Amanda Han's Book On Tax Strategies, about taking every possible tax deduction.  A question the book doesn't seem to answer- If I deduct everything I can doesn't that make the property cashflow less or even take a loss on paper?  And when I try to buy my next investment property, mortgage brokers don't want me owning properties taking a loss.  So would I be shooting myself in the foot when trying to scale and deduct as much as possible at the same time?  How do you find a balance with this?  What am I not understanding?
