As these are newer townhomes, and as there are two styles available, you can see from their website that there is a price range related to each style. I agree with the earlier answer about supply and demand regarding condos and single family homes, that the market, supply and demand in particular, will dictate resale value of any property.
As a Nurse Practitioner and a Realtor, my answer also includes recognizing the aging of the population related to baby boomers. The benefits of a condo that will prove valuable to baby boomers and affect resale to this population include: no outside maintenance, the beauty of all of the townhomes around you having been maintained in a lovely fashion, snow removal, trash removal, rules and regulations to maintain the complex in a favorable fashion which can be related to pets, etc., pool maintenance, fitness facilities, standards for using and maintaining the club room, energy star appliances and more. All of these items are what my clients who are looking to downsize, live more carefree in their later years, but don't forget the young population who have two people working who don't have time or desire to maintain a single family, as well.
Ultimately, the best way to determine if you are interested in a property or to make decisions regarding townhome or single family and more is to have a Realtor at your side throughout the entire process. I can provide you with the details you need to make the best purchase possible in today's market and to assist you in selling your current home, as well.
