Perhaps I may be of some assistance.
There are a number of issues here, but fundamentally, if the house is still habitable, he should be paying you rent. If there's a written lease between you and the tenant, that probably addresses who is responsible for rent payment, in the event that an intervening cause such as Hurricane Sandy reduces the habitability of the house. Please call 212-350-9576 to discuss.
