It renders pattern recognition unnecessary.  

The reason I mention this is a rise in prices based on credit expansion is only sustainable if real wages increase (more income means higher mortgage payments are affordable) or interest rates go down (although amount of credit increases the monthly payment is not increased therefore an increase in income is unnecessary).   

Its unnecessary for all of this between both of us. 

However I am a smart investor that believes taking unnecessary risk is foolish. 

Do not create unnecessary turnover & do not expect the tenants to live how you live.

I won't stop shopping at Kohl's once I hit a million because it's unnecessary to shop at higher-end places.

A leasing fee of 1/2 or 1 month's rent is not unusual and 10% is pretty standard as well, but it may be unnecessary for high-end properties.

I think there's a lot of hype around this that is probably mostly unnecessary unless you're in a very tenant-friendly state.

I have determined that 0% interest reserves in savings account beyond about $5000 are unnecessary for me, regardless of how many properties I have.

My guess is the penalty to break the contract is less than what you are going to pay in unnecessary repairs.
