While I agree that HOA's can be a good thing, my one and only experience with them was awful.
After my divorce, I bought a townhouse on a private road, with approx 25-30 townhouses on it. The unit I bought was owned by an eldery lady who had passed away. It was just myself and my 2 year old son living there. I didn't realize until I moved in that the entire street was pretty much older/retired people. There was one other "single mom" on the street with one child, and a man who had his kids every other weekend and maybe a night or two during the week. As soon as I moved in there was a notice sent around about that leaving "children's toys and bikes" out in the yards was not acceptable. My son was 2, he didn't have a bike, and the only toy that we had even put outside at that point was a big bouncy ball, that was kept next to my back stairs, hidden from view unless you were standing on my back stairs. I thought it was weird, until I met the other single mom and she told me that the older people were not happy about having kids in the neighborhood. Ummmmmmmm, this was NOT 55+ community, it was just a dead end street of townhouses. Whatever.
My next issue came when I realized that the "guest" parking spots were pretty much "assigned" parking by unwritten rule. Each townhouse had a spot to park in front, then there were a bunch of guest spots... no designation as to which spots were for which units, it was just general guest parking. Well, I worked nights (and still do) and at the time my ex and I weren't on friendly terms, and he didn't take my son on the nights I worked all the time. My brother generously offered to stay at my townhouse the nights I worked so that my son didn't have to go to my moms, so he could have some stability and sleep in his own room. Well, at a meeting I guess it was brought up that I was having a "frequent overnight male guest" park in a spot that someone else felt was their guest spot due to the location of it. I was furious. It turns out that no one held specific claim to any guest spot, but the fact that someone was being that snarky pissed me off. I also told one of the HOA leaders that MY BROTHER will park in any guest spot that is open on the nights he babysits MY SON, HIS NEPHEW so I can GO TO WORK to pay my mortgage. I was SO glad to move out of that townhouse 2 years later.
