Also if you have public transportation nearby, some tenants will not own cars. 

A modular home is built in a controlled factory environment in sections which are then transported to, and erected upon a foundation at the build site.Palm Canyon Mobile Club is a mobile/manufactured community. 

The buyers/tenants have already factored things like crime, schools, transportation, etc into what they're willing to pay.

We purchased a preowned 2020 manufactured home located in Bonanza from the MLS to transport and place permanently on the property in Burns.

Tenants that pay well are ones that live near major transportation.

think of the nightmare that a company would go through trying to get regulatory permission to transport truckloads of it across state lines).

My point is, people have to live, some people stay in "warzones" because it close to their job and they don't have transportation or family is close or its the only place they know or maybe they don't think it's a "warzone", it just home etc.

First reading your question I thought tenant was going to say she's building a greenhouse or some insulated contraption for a school...no.Bottles with sugar syrup attract ants and bugs.As I read your response maybe she has an emotional hoarder problem or no vehicle to transport the bottles.

My current method is to look at 5 key metrics to narrow down to 5 states and then narrow down further to 5 specific areas from those states- all in this order of importance :1- population growth/“opportunity”2- crime rates3- education4- landlord favorability5- economic stabilityOnce I have narrowed down further I would also likely include a few other potential things like public transport, specific school ratings etc.Is my approach way off? 

These are completely unregulated for now but regulations could be implemented in the future.
