This kind of system doesn’t let people do something as simple as postpone repairs until they can get favorable financing, and ends up a tax on the poor or different to protect an asset for the majority landowners in my view.
HOAs started as a way to handle common infrastructure, like drainage. They allow a few homes to share drainage, without sticking all of the costs of maintenance to the homeowner who happens to have the pipe on their property.
In my case, my HOA carries property insurance for undeveloped land, maintains a grassy cul-de-sac, and maintains a fire road. (I personally spend about 2 hours a year trimming growth on the fire road because so many people walk on it.)
As far as saying that an HOA is to keep the loons out, we did have a hoarder live around the corner from the HOA. The people who lived across the street couldn't sell their home. (They had kids and wanted a larger house.) Could the HOA really do anything about the hoarder? I know the people who lived around the hoarder all put a lot of pressure on hee, the town condemned the house, and eventually it burnt to the ground. At least my with HOA, there isn't any good way to "evict" a loon who makes a mess.
In the case of the hoarder, she owned her home outright. The town put liens on the property to cover the cost of cleaning up the lot. But, she still owns the lot and hasn't put it on the market. (She also places things on it, too.)
Dramatic license aside, I'd hate to live anywhere where property value (or residents' senses of well-being) was so fragile that it couldn't handle a purple house.
Tangentially, Victorian houses were frequently very colorful. The lack of color photography leads people to think of them as drab, depressing shades of gray. But nothing could be further from the truth. HOAs that restrict colors to a boring beige are doing a disservice to their neighborhoods.
How is that someone else's problem? Ironically, in some areas around me properties without HOAs are priced and selling a couple of 100ks higher than ones within HOAs.
An understandable sentiment. How much are you willing to pay for it? If you have a $1.5 million mortgage and that loon shows up next door and paints their house purple, your house might lose $300,000 in value. Same with the other neighbors, who also pay mortgages but aren’t as compassionate as you.
What happens when your spouse gets a sudden offer to relocate and you can’t make your money back on the house?
