Let's say you already own a duplex in Salemtown and you don't buy my whole argument that we need to develop a more balanced housing stock for the sake of long-term growth in our neighborhood. Let's say that you are perfectly happy with your duplex and you do not understand what this scrape over the Salem Gardens properties is all about. I have not encountered any local duplex owners who feel that way, yet. But let's say there are some out there among the silent readers.
Allow me to take an economic angle and suggest to you that saturating the Salemtown market with more duplexes actually decreases demand for duplexes here, which decreases the value of your duplex at resale time. I own a single family home, which might lose a little value if more single family homes are built, but all strata of potential buyers in a market have an interest in single family homes if they can afford them. That is a shot in the arm to my home's resale value. A much more limited strata of the market demands duplexes, especially when single family homes are available.
So, it is a mistake to glut the market with duplexes, which will generally take longer to sell than single family homes. It hurts the long-term development of the neighborhood. But more importantly it hurts those of you who already have duplexes that will eventually be resold. It is in no Salemtown resident's interest to put 6 duplexes at the corner of 6th and Garfield; it only suits the narrow interests of the absentee landlords.
