New York Consolidated Laws, Private Housing Finance Law - PVH § 403. Occupancy

1. The dwelling units in any existing multiple dwelling aided by a loan pursuant to this article shall be available solely for persons or families of low income during the period in which any part of such loan remains unpaid, any exemption and abatement from taxation on the property resulting from the installations, alterations or improvements made with such loan remains in effect or for a period of at least ten years from the occupancy date, whichever is the later.

2. Any person or family in occupancy whose income precludes the inclusion of such person or family within the definition provided in paragraph a of subdivision three of section four hundred one of this article may be required to pay a rental surcharge in accordance with a schedule of surcharges to be promulgated by the agency.  In determining imposition of any such surcharge, the agency shall consider factors such as the net operating income and debt service coverage ratio of the property aided by a loan pursuant to this article.  Rental surcharges collected pursuant to this section shall be paid by the owner to the municipality which has granted such owner tax exemption or tax abatement pursuant to any law authorizing the granting of same, as reimbursement to such municipality therefor.  In the event that such tax exemption and tax abatement have not been granted, or in the event that a sum equal to the total amount of tax exemption and tax abatement granted to the owner has been paid to the municipality, the excess, if any, of surcharges shall be paid to the municipality in reduction of the loan.
