Pretty good overview of how/why these deductions reduce your taxable income. Couple of things to note.
Depreciation is recaptured if you sell an asset for more than its depreciated basis. People sometimes get into trouble with this if they rapidly depreciate real estate and then sell it. Even if you sell for less than your purchase price it is possible to owe taxes.
You also aren't going to be able to pay no taxes since you do need to realize some income to pay for mortgage/rent, food, transportation, etc. I guess if you had assets you could borrow against it would be possible to pay for these using the loan proceeds (which are not taxable).
The thing I don't understand with these loan arguments is: don't you eventually need to pay taxes in the income you use to repay the loan? It seems to me that folks who take out such loans are just kicking the can down the road.
This is exactly why many people became landlords, but changed their mind and found that there is no way out. You might decide one day to buy some investment property, but after a few years when you lost interest in the pursuit, quitting would actually give you a huge tax headache in the form of unrecaptured section 1250 gain. This is unfair. You can quit a W-2 job or a hobby without tax consequences.

But in the U.S. you can't rapidly depreciate real estate, it is generally straight-line over 27.5 or 39 years (residential vs. non-residential). The gain on real estate due to depreciation is technically referred to as Section 1250 gain, and if there is no gain (which is calculated against your adjusted basis, not purchase price), then it follows that there is no Sec. 1250 gain (often mistakenly called "depreciation recapture").
