Does anyone know why the two available apartments in this building have a similar maintenance, yet one appears to be much bigger with more than 2x the asking price as the other? Apartment 124C is a 12 room 4 bed 4 1/2 bath with outdoor space currently asking $7,900,000 (original ask $9,250,000 on 1/15/2013, sold for $6,250,000 on 4/15/2008) with a maintenance of $5291/month. Apartment 8/9/10A is 6 room 3 bed 3 1/2 bath with odd layout currently asking $3,395,000 (original ask $4,350,000 in 2/16/2012, unknown last selling price) with a maintenance of $5215/month.
