Demographics show that the average age range runs from 25-35.

It's a specific and targeted scam on the REI industry's most vulnerable demographic, which makes it all the more infuriating.I know you've likely learned a ton from this experience, which is I guess the silver lining.

I think ListAbility has a bit more flexibility with demographic data. 

People left because the place was run down but not because of a bad area.When I look at value add I look at demographics and the crime going on.

I've seen "studies" that take the average rent in Chicago (which gets skewed by high income $10k/mo+ rents), and average that with say the average rent in say Urbana, and use that as the average to compare against without taking into account the # of rentals in each.Chicago neighborhoods are going through natural changes that cycle over the years and change the demographic makeups.

Should I be targeting a demographic?

The areas are comparable in my experience (rents, taxes, demographics).

Location and demographics matter here.

This could definitely be due to the demographics of FF users changing (i.e. more non-medical professionals using the site now). 

While the location is cheaper now because it's relatively close to I-5, it also attracts a lot of less-than-desirable demographics stemming from the major drug epidemic which the entire county is dealing with, especially the constant petty thefts and car prowls from homeless addicts seeking a few bucks worth of something to sell for their next fix.
