As do private dirt roads. Very handy.
I'd rather live in a real suburb - e.g. large plots, wells, septic. I'm not ideally fond of dirt roads in general, but nobody is going to be road racing a 1AM. It's at worst a minor inconvenience.
But for 80% of people its a deal breaker. Good! Now I found something I don't mind too much that saved me loads of money. And dirt roads come with no HOAs as a bonus.
Find something where your preferences run counter to the masses and profit!
