No, this is not an adult community. My sister is 38 years young. These are Single Family Homes but they are "attached" to another Single Family Home, like a "duplex".
For more details, check out the web reference below or contact me directly.
These planned communities are "Attached" Single Family Homes; which means 2 homes share a common wall. Recent market data indicates resale values around $200,000.
As far as your question, "Is this a good neighborhood?" I can only answer by saying, My sister and her husband live in Southwinds 1.
