I suggest not putting yourself in a position where your defense for an illegal activity is that everyone else does it.

I suppose I could gather witness for my defense from all the brown people I rent to, which so far has been 100%.

Multiply those probabilities by one another, and you have a huge undercurrent of risk ballooning and compounding with each passing month. 

Your only defense is stringent selection criteria for tenants and to NEVER EVER EVER take a security deposit.

The real power of the ability to defer payment of capital gains tax in a 1031 exchange lies in the compounding nature of your use of that deferred tax.  

Compounding that we are replicating in other states with different trade bases, municipal guidelines, lending practices, etc.

Pumping the tank when it needs it and running a camera through the lines are the best line of defense. 

Which does not create profit, it's creates capital today via kicking-can and compounding future expense. 

The time savings compounds very quickly when you consider things like getting a property ready to rent (especially if it takes several days/weeks), semi annual inspections, repairs, and any other random reason you have to go to the property.

The concentration of these people in C-U is compounding: C-U feels more cosmopolitan while surrounding areas feel more strange to outsiders.
