Just any holes or concerns that I should have so that I could make an informed decision. 

I know this will be a large financial decision that impacts me for years to come and I want some thoughts on my strategy.

I am able to run reports on a dime and make decisions quicker on properties I am considering.

The problem with pointing a finger is a) at the decision making of a government entity who will have their own rules posted b) how long a time frame from close to the zone change and how long was vacant... c) what is the difference in value?

So take this into account in your decision.

You are never going to learn everything but the main thing is just feeling confident enough to be able to make an educated investment decision. 

It all starts with decisions driven by data.

Did this influence your decision to rent to this person?? 

(Every decision you make from here forward is based on this decision.)2) I always suggest working with a broker, preferably a national broker who is licensed in all 50 states, so if you decide to invest elsewhere or want to bundle your personal protection and you're in another state, you can keep everything consolidated. 

Typically we request to review their financials and make a decision regarding their creditworthiness ourselves.
