I don’t think a twin home has an advantage here… but I owned one in the Philly suburbs… a 100 year old, victorian style, twin home.

The advantages
– I had one less exterior wall to heat. That’s not a value in our climate… but back east it reduced my heating bills.
– I had the benefit of a guard dog, without the work. (neighbors dog barked at people coming onto my porch, lol.)

Mine was fee simple… property line ran exactly through the fire/party wall. No HOA’s. Only covenant prevented me from having a tannery or a manure pit in my back yard. (Seriously.) My neighbors on the other side of the wall were great… it was a good experience.

That’s funny about the tannery and manure pile. I’ll have to check my CCRs to see if there’s anything like that.
