         Re:      Registration  Statement on Form S-8 relating to the First Real
                  Estate Investment Trust of New Jersey Equity Incentive Plan

Gentlemen:

         We refer to the Registration Statement on Form S-8 under the Securities
Act of 1933, as amended (the  "Registration  Statement"),  filed on this date by
First Real  Estate  Investment  Trust of New  Jersey  (the  "Company")  with the
Securities and Exchange  Commission  (the  "Commission"),  to which this opinion
letter is attached  as an exhibit,  for the  registration  of 230,000  shares of
beneficial interest, without par value, of First Real Estate Investment Trust of
New Jersey  ("Shares"),  which have been  reserved for issuance  under the First
Real Estate  Investment  Trust of New Jersey Equity  Incentive Plan (the "Equity
Incentive Plan").

         We have  examined the original or a  photostatic  or certified  copy of
such  documents,  records,  and  other  information  as we deemed  relevant  and
necessary as the basis for the opinion set forth below. In such examination,  we
have assumed the  authenticity of each document  submitted to us as an original,
the  conformity to the original  document of each document  submitted to us as a
certified of photostatic copy, and the authenticity of the original of each such
latter  document.  In addition,  we have  assumed,  in rendering the opinion set
forth below,  that any share  certificate  evidencing  any Shares of the Company
registered  by  this  Registration  Statement,  when  issued  under  the  Equity
Incentive  Plan,  will have been duly executed on behalf of the Company and will
have been  countersigned  by the Company's  transfer agent and registered by the
Company's registrar prior to its issuance.


         On the  basis  of  our  examination  mentioned  above,  subject  to the
assumptions  stated and relying on statements of fact contained in the documents
that we have examined, we are of the opinion that the Shares registered pursuant
to the Registration Statement have been duly and validly authorized and reserved
for issuance and that upon the  issuance of such Shares in  accordance  with the
provisions  of the Equity  Incentive  Plan,  the Shares will be validly  issued,
fully paid and non-assessable.

         We  consent  to  the  filing  of  this  opinion  as an  exhibit  to the
Registration  Statement. In giving this consent, we do not thereby admit that we
are within the category of persons whose consent is required by Section 7 of the
Securities Act of 1933, as amended,  or the General Rules and Regulations of the
Securities and Exchange Commission.

                                                  Very truly yours,


                                                 /s/ Giordano, Halleran & Ciesla
