Below is an exert from an article, written by Kimberly Young at HM Properties (June 26, 2014):

“A Duet, in real estate, is defined as two homes that are owned individually but are housed under one roof; one building. A Duet is not a Duplex. A Duet is similar to a townhome or a condominium, except for the fact that it shares just one common wall. And, unlike a duplex, Duets are individually owned.

As seen recently in the Charlotte Business Journal, Grandfather Homes, is introducing this new housing option to the Charlotte market. Grandfather Homes is currently working on their first Duet project at 725 Ideal Way in Dilworth, and delivery is expected in the first quarter of 2016. Both Duet units at 725 Ideal Way will be around 2,500 square feet and will start at around $625,000.”
