Good question. I wrote a blog right here on Trulia to give buyers a pros and cons comparison.
By the way I personally would not recommend Parkchester condos to anyone. I have had clients that have told me stories of maintenance issues as well as the high maintenance (after all it is a condo and you are paying taxes on top of the maintenance) that this is more like a coop cost wise and yet without the benefits of a coop.
If you have any more questions I would be happy to answer them for you.
