If an owner of premises who is not the person in receipt of the rents and profits gives notice to the local housing authority of his interest in the premises, the authority shall give to him notice of any proceedings taken by them in relation to the premises under any of the preceding provisions of this Part.
Nothing in the preceding provisions of this Part prejudices or interferes with the rights or remedies of an owner for breach, non-observance or non-performance of a covenant or contract entered into be a lessee in reference to premises—
and if an owner is obliged to take possession of premises in order to comply with such a notice, the taking possession does not affect his right to avail himself of any such breach, non-observance or non-performance which occurred before he took possession.
