I live in a nice neighborhood. They also included about 12 'low income' style houses in the mix. I believe it is a requirement where I live.
These are houses, which are purchased. Not rental units. I have no idea how they maintain the 'low income' ideal when houses are sold.
But here is what I have found:
The turnover rate of the low-income housing is probably triple of the 'regular' (somewhat high-end) houses.
MOST of the people are good/fine. No problems.
I would say that 75% of the 'problems' in the neighborhood stem from the low-income section. (My house is close by, I see what is happening) 75% of the problems yes, but this is in a neighborhood that has very, very few problems. So we're talking about maybe 3 police actions per year that I see.
75% of the traffic is also generated by that small collection of homes. Like these people drive a lot.
The biggest difference though is the age of the residents. In the 'regular' homes, the homeowner age is well above 50. I am on the young side, and I turn 50 in two weeks. I think two other guys are below 50, the rest are much older.
The low-income housing is made up of lots of younger people. 20 somethings, 30 somethings.
I don't think income has much to do with the 'problems', I think it has more to do with age. And honestly, the number of 'problems' is very low. It seems like a bunch of normal people, who couldn't afford $700,000 homes, but were able to live in a nice neighborhood for maybe a third of that price.
OH! The only issue I have is with parking overflow. Every once in a while a new group of people will move in with a plethora of cars which they start parking in front of other houses. The low income area is more like a condo complex (but they are detached) and they have their own parking areas, but they do get full. So people park on the normal street. All of the houses have at least 3 car garages, and giant driveways. We aren't even supposed to park on the street overnight...but the low-income residents didn't have to sign a CC&R stating they wouldn't park on the street...we did.
That's it. These are all really small issues. But I do believe that the people living in the low-income area benefit greatly from being in a nice neighborhood. I think it's fine.
