At the townhome I was at, our HOA funds were debited often by having to fix it. The association president was called often to come manually open it. And it becomes a liability in trying to attract drive-bys when you go to sell it.
The semi-plusses: the illusion of security (robbers on foot could have jumped our 4′ side gate)–maybe there are other models that actually are more secure. “Gated community” sounds nice when you sell it. Less drive-through traffic, but that wasn’t a problem in the first place since the street leading into my community was an obvious dead end.
