For instance, you have ordinary income (income from performing a service like flipping a home, selling inventory, or working a W-2 job).

For instance, you wouldn't put expensive marble kitchen counters in a rental (unless the market supports doing so.)

For instance, I may work on a cost analysis excel spreadsheet today from my MacBook Pro, leave to see a property and take notes in the same excel spreadsheet on my iPhone and get back home and resume working on it again on my Mac.

For instance, a rudimentary example:Total $$ Invested: $100,000Primary Investment: $80,000Secondary Investment: $20,000Total Profit: $20,000CM @ 10% Fee off top = $2,000Remaining Profit: $18,000Primary Investor @ 80% of remaining profit = $14,400Secondary Investor @ 20% of remaining profit = $3,600My only thought is that I, as the primary investor, have put in a ton of time finding the deal and financing it in my name.

I find that the influx of people from other parts of the country (the soon to be 3 Californias, if they have their way, for instance)  and from the midwest have really brought back the Phoenix (Maricopa County) markets.

You don't have to accept all felons, for instance I know a lot of housing that accepts non-violent offenders, or first time offenders, etc. 

For instance every time you get a credit card bill, that new balance is reported.

For instance, they determine the formula for calculating bedroom size.  

Think for instance you go to your local drug dealer and sign a contract for 3 kilos of Cocaine at $50k a kilo and when it comes time to pick up your product he is selling for $55k.

For instance, changes to tenant laws, enactment of rent control, continual increase of property taxes, etc. could all throw the math out of whack.
