>I don't it's possible for a multi-unit apartment building to sell single units. Ok. I own one unit of a 4-unit building, which was as far as I know built to sell, not rent, roughly 30 years ago. It is definitively not a condo, in terms of the ownership structure and the portion that I own. No HOA either. So your point is that it's not an apartment? Empirically, it is true that people don't call it an apartment. But it has the same square footage and decor as nearby apartments. The only thing approaching a fundamental difference is that it's on two levels, with bedrooms upstairs.
