The terms and conditions of such leases or extensions of leases shall be as agreed upon by the lessor and the lessee, provided that the rent for such apartment or unit shall not be in excess of reasonable rent for comparable apartments or units in the same market area as such conversion building.
Such leases or extensions shall not be required, however, in the case of any apartments or units that will, in the course of the conversion, be substantially altered in physical layout, restricted exclusively to nonresidential use, or be converted in such a manner as to require relocation of the tenant in premises outside of the project being converted.
