Inner City vs. Suburban Absentee Owners

[Alvin Grier]

I've noticed that our response rates for our absentee owner mailings in the suburbs are nowhere near as high as they are in the city.  

I was just wondering if anyone else has ever experienced or observed that as well.

The big city I'm closest to is Detroit, and I compare the responses there with what we get on the surrounding suburbs.

I've also noticed that very few SFR's in the suburbs sell FSBO, and it's the complete opposite with the city of Detroit.

Outside of the huge difference in property values in the city vs. in the 'burbs, are suburban sellers just more sophisticated, and tend to sell via REALTORS more so than their inner-city counterparts?
