I have to sort of agree with valkyrie.
Although, I'm going to take a far-fetched guess and say maybe some of the older people who are 'complaining' about the way their collegiate neighbors choose to display their furniture, etc., probably lived there long before the collegiate students moved in. Most colliegate students are around for 4-5 years, and I would guess no one would just want to move into a house next to someone who lived like that... at least I wouldn't.
Perhaps the houses the collegiates were living in weren't always like the way they are now with couches on the front porch and 10 cars in the front lawn. Maybe the people who lived there before didn't do that sort of stuff, moved out, and the house got rented to the students who put their rickety old ugly brown plaid upholstered chairs in the front of the house and now the homeowners next door are upset about it. Wouldn't having a neighbor like that lower your own property value if you wanted to move?
I've never been to Alabama though, so I don't know... I'm just taking a guess here.
