Dumpster, permits, and inspections $15,000.

Some of the laws in NY changed recently and you are required to obtain a certificate of no harassment, No permits will be issued until it is resolved.You will need to work with the current tenants for this certificate to be approved which can take up to a year or more, Definitely something big to consider.
