There's no singe answer to your question. Some older communities and rural areas have no HOA fees. If you are looking at "regular" subdivisions, I usually see HOA's from 25-50 dollars per month. These are communities with little or no amenities. Sometimes these subdivisions are in larger PUDs (Planned Unit Developments), and then there is a second HOA fee for that as well. Then you can be looking at communities with lots of amenities, clubhouses, pools, restaurants etc., and those fees can be much larger, $100+ per month. Then there are the country clubs...huge fees!
If you are looking to purchase a new home, make sure your agent double checks the stated HOA fees on any home that you're interested in. I've seen many mistakes on listings, even the best agents can be unaware that the fees/dues have gone up or can miss the PUD fees. And if you get really serious about a home, check to see if there are legal charges or pending litigation that involves the HOA. It might not be a deal breaker, but definitely something you want to know about!
