Some of the Items you mentioned are good way to add value, but are not key factors.Main key factors i can think of right now are:1.

I think Phoenix is an interesting spot because the x-factor is that people are moving there with an overflow from unaffordable spots like LA and Seattle. 

I deal with inspector in NYC and Westchester County and you tread lightly and sometimes you can't do anything about it. 

Some of the people I deal with are very confrontational, others we have a drink and write checks to make the numbers work out regardless of the paper work.I'd say if there is a good level of trust why doesn't the borrower just pay you for Y note from the proceeds of the sale without anything extra on the payoff demand. 

Another complicating factor is that several have sprinkler systems, which makes the “separating” more difficult.

After factoring in closing costs it is unlikely to be to your Beirut to refinance.

A lot of factors and options are available.  

This will have considerable factors as well.

I am looking to purchase a multifamily property in the Atlanta, GA area. 4-12 unit is ideal.

There will be ups and downs and market swings based on both internal and external factors beyond our control but I expect your home will continue to outperform inflation rates.
