4. The receiver shall be discharged upon rendering a full and complete
accounting to the court when such condition has been removed and the
cost thereof and all other costs authorized by this paragraph have been
paid or reimbursed from the rents and income of the dwelling and the
surplus money, if any, has been paid over to the owner or the mortgagee
or lienor as the court may direct. However, at any time, the receiver
may be discharged upon filing his account as receiver without affecting
the right of the department of real estate to its lien. Upon the removal
of such condition, the owner, the mortgagee or any lienor may apply for
the discharge of the receiver upon payment to the receiver of all moneys
expended by the receiver for removal of such condition and all other
costs authorized by this paragraph which have not been paid or
reimbursed from the rents and income of the dwelling.
5. Anything herein contained to the contrary notwithstanding, a
temporary receiver appointed on the return of an order to show cause
served only in accordance with subparagraph two of paragraph c of this
subdivision shall not, without express order of the court, make any
repairs or improvements to the property or incur any expenses in the
operation thereof during the period of his temporary appointment except
such as may be necessary to remedy or remove the immediate condition
which called for his appointment and to the ordinary operation and
maintenance of the property. For such specific purpose the receiver
shall be entitled to let such contracts and undertake such expenses as
may be necessary to accomplish the specific results without
advertisements and without procuring competitive bids.
