Hmmm, Streeteasy's on stats are a little bit off.

It's because generally one-bedrooms don't appeal to either of the two important categories of buyers--singles just starting their careers (studio) and folks with families (2 ). Studios also appeal to students and pied-a-terre buyers. Usually by the time someone is purchasing a real 'home' they're looking for something they can grow into. A one-bedroom is far less appealing for that than a 2.

without factoring in individual views, reno, bldg amenities, etc.., typically larger apartments are in less supply trade for a higher $ per sft

With that said, every bldg is its own little market and I would look at the trend in the targeted bldg
