Does the difference between detached, semi-attached and attached change my Alpharetta home's value?

The difference between a fully detached, semi-attached and attached home changes an Alpharetta property's value mainly through privacy, noise and lot size, with fully detached homes generally commanding the highest price for comparable square footage. Semi-attached and attached homes can still hold value well if the HOA and shared-wall construction are well maintained. Joel Boss compares each structure type against its own set of comparable sales in Fulton County rather than one blended figure.
