Tax Abatements Dumbo & OBBP

I cannot seem to find a clear answer to this question. How can I find out definitively when the tax abatements of 1 Main, 70 Washington and One Brooklyn Bridge Park expire? I’ve checked old posts and cannot find the answer either. Brokers seem too vague. This should have to be listed with the property details by the selling agent! Any help would be much appreciated.
