1. Overpriced compared to other condos that have sold recently
2. When viewed in person, something is "wrong" with the condo that aren't shown in the photos. That could range from an old heating system, to an obviously junkyard neighbor, to a odd layout in general. It depends. You would have to look at the property.
3. Condo fees are super high
4. Problem with other condo units - people who live, condo association doesn't have funds, foreclosure on a condo or condos.
Anyway, my 2 cents (former realtor).
