In order for you to [ay a coop without approval you will need to buy a condo or a sponsor coop unit which requires no board approval. You will need a preapproval letter from a reputable mortgage broker or bank.
I have been living in Riverdale for 11 years and selling here for 11 years I work with Weichert Realtors House and Home
I do have sponsor units for sale if you would like further information I can be recahed on my cell 917-570-8420
What you probably need to be looking for is a sponsor unit. An apartment where you do not need board approval to get accepted (there is more to a sponsor unit than that, but it is easier to explain verbally). There are several that would suit your needs in Riverdale, but you should make sure your credit is good enough to get a mortgage (unless you are paying casn). Banks are pretty difficult these days so you should go with a mortgage broker that you can trust and has experience with Co-ops. I have some suggestions if you would like, or if you have a good person, go use him/her.. Please contact me if you have any questions. I own Weichert Realtors - House & Home in Riverdale on Kappock street and my kids go to PS 24 so I do have quite a bit of experience in the area.
All the best,
