I was able to scrape up enough comps, with two recent sales in the neighborhood, one in a nearby city, one slightly older sale in the subject's city, and one older sale in the neighborhood, without having to use any three-units or two-houses-on-one-lot comps. I actually somewhat agree—I was thinking this may be over-improved—but there are a few blocks of these townhouse-style comparables with limited recent sales data. I performed a search farther back, up to five years, to analyze sales data, and they consistently show the highest sale prices in the whole city for two-unit properties when they do sell, with large increases year-over-year based on the limited sales data. The main issue is there are no recent sales of these as large as my subject nor as updated, but using an updated one from a nearby city, an updated older sale, and an older sale (two years old) that bracketed the GBA, and then two recent sales that adjusted up due to smaller size and inferior condition, my subject is just at the high end of the value range for two-units in the city based on the sales data—mostly due to the constricted housing stock of these townhouse-style duplexes in this city (which is predominantly owner-occupied), where, when they do sell, they are significantly higher than standard two-story/upper-lower duplexes, and resale history of these sales (which is limited) shows large increases year-over-year. So I think using the older and farther sales as support, along with more recent sales in the neighborhood, provides good support for the value, albeit still at the high end of the neighborhood range for duplexes.
