Just for future reference, you are entitled to the correct documentation shortly after you sign an agreement of sale in PA for a property with any type of planned community docs. Then you have 5 days to terminate if you are not happy with what they say. My experience is that the papers you are given by the seller or if you call the management company are not always correct.
If you like the neighborhood, I would suggest you interview and hire a good buyer's agent and have them help you with the due diligence. That should include recent sales, any known capital improvements and any other potentail expenses that the HOA might be talking about (but have not yet adopted), etc. Best of luck to you. The Strafford area is a very good one to find a home in.
