It's long term renters that increase the probability of issues/squatting/ill-maintenance cropping up, and generally start a long term degradation of the neighborhood. Long term renters also seem to buy ridiculously overpowered audio systems, and run them in such a way that one can hear the thump-thump bass, a block away. Not to mention they often pack like sardines into a place, and then you have 4 or 5 autos per residence.
