To these responses I just cut/paste the ad narrative into an email reply.

Rehab is nice so I don't think that will be a concern, this is also off street parking so ones with garage will be favored more if you are priced the same. 

One concern that I have is that I need to be able to sustain this during a downturn.

I'm definitely still looking at it, but one concern is the population growth, it seems to be decreasing slightly? 

The tenant is understandably frustrated and has mentioned safety concerns due to slipping hazards caused by the water.

This discrepancy has left me confused—should I be concerned about this?

We could cut things and not rely on it, but it would be a little uncomfortable.

The advice is downright bad; not applicable to the average Billy & Barbara, some signs of bragging among other concerns.

To answer your question (that wasn’t actually aimed at me) my concerns are investing in an area that I’m completely new to and building an out of state team that will be effective. 

For example, I am a little concerned about some aspects of the business cycle recovery and a potential for a double-dip so I lean toward the safest part of capital stack which is debt (or low-debt equity).
