You are at the very low range of condos in Garden City, if at all, but there might be one-bedrooms in the range. Check out
www.gcnews.com for all the local real estate listings, including condos. The GC school district is always in the Top 10 of Long Island, and by all accounts, outstanding. You will be much more in your price range in Westbury, but the school district there is really underperforming and faces many challenges.
