There are good and bad points to the associations, but I live in one and I would not want to be without it.
Some folks move to the country so they can do whatever they want on their land. Others move out looking for a nice place to live. If you fall into the latter category, then you should look at an association as a thing that will protect your investment and protect you from people who have different values than you may have.
In our assocation we are only allowed to maintain the neighborhood and to enforce the covenants. But a new family moved in next door, they let their dogs run everywhere, they parked a large commerical truck in the driveway. Both are forbidden by the covenants. A letter from the association stopped both. Another neighbor decided not to cut his lawn. Again that was fixed by the assocation. Another wanted to build a pole barn sized building of dubious quality that did not match his home. Rules prevented it; he is allowed to build a pole barn, but it must use materials and colors that match his home. Lot sizes where I live run from 2 to 6.5 acres, some folks own multiple lots, but when your property is 2, 5 or even 10 acres, it is hard not to see what your neighbors do with their property.
So if you are the type who wants "anything goes" on your property, or you won't mind if the property next door to you is allowed to run down, complete with cars on blocks, etc, then do not move into an association. If you want to see your property values protected, and can live with some reasonable rules, then look at buying into an association. But realize that all associations have their own rules, you may find some that are very rigid, and others that are very lax. Read the rules before you buy and make sure they will suit you and your needs.
Personally, I don't want a neighbor parking a semi-truck on the 5 acre lot next to me, nor do I want a commercial chicken operation down the block, or a home based business on my street that draws extra traffic on my road. I want people to build out buildings that match their homes. I don't want yards littered with junk cars, yapping dogs, or leaking septic fields.
Don't get me wrong, I am not in favor of strict restrictions, I've seen some places that determine your paint colors! But there is a reason that some people prefer to live in an area that has an association and restrictions.
