However I haven't found any clarification on this aspect yet. 

My preliminary research on Zak has not shown much negative things yet.

This implies renting is initially cheaper than buying and at high LTV, rentals are initially cash flow negative.  

I have always been willing to take vouchers, so that aspect did not affect me when the law changed. 

Personal usage will negate the losses from the cost seg in the first year, so we suggest avoiding it.

IE if you were to be "negative" you could be thrown out which is a pretty stiff penalty given the costs. 

I'm not sure why not - one of the great parts about real estate investing is that you can build a team around you for aspects you aren't as strong at or simply want to delegate to someone/expert and do the others yourself - look up "Core 4" for example - where you can have an agent, lender, manager, contractor all at once for your investments and can theoretically just let them do all the interactive work

Plus I recently got a brand new calculator, wanted to see what out of state investors though the most important aspects of deciding between to similar rates cap rates in 2 varied size apartment. 

Before buying or renting in an unfamiliar neighborhood, you should check the following two sites: SpotCrime, AreaVibes,These sites provide valuable information, including Livability Scores, which cover aspects such as crime rates, employment, health, housing, schools, shopping, and more.well, anything can happen anywhere.

Prices haven't fallen, and rents haven't moved up enough.Investors either need to work harder, be more creative, accept negative cash flow, or sit on the sidelines.
