         Re: FURST Mortgage Loan Trust 1998-B, Mortgage Pass-Through
             Certificates, Series 1998-B

Ladies and Gentlemen:

           We have acted as special counsel for First Union Residential
Securitization Transactions, Inc. (the "Depositor"), a North Carolina
corporation, in connection with the purchase of certain first lien, fixed rate
mortgage loans (the "Mortgage Loans") pursuant to the Mortgage Loan Purchase
Agreement, dated as of July 1, 1998 (the "Purchase Agreement") between First
Union National Bank, as seller (the "Seller"), and the Depositor, and the sale
by the Depositor of the Mortgage Loans to FURST Mortgage Loan Trust 1998-B (the
"Trust") created by the Pooling and Servicing Agreement, dated as of July 1,
1998 (the "Pooling and Servicing Agreement") among the Seller, as master
servicer and as trust adminstrator, the Depositor, and Norwest Bank Minnesota,
National Association, as trustee and document custodian (the "Trustee" and the
"Custodian"). In exchange for the Mortgage Loans, the Trust has issued to the
Depositor two groups of Mortgage Pass-Through Certificates, Series 1998-B, with
the first consisting of Class 1A-1, Class 1A-2, Class 1A-3, Class 1A-4, Class
1A-5, Class 1A-6, Class 1A-7, Class 1A-8, Class 1A-9, Class 1A-10, Class 1A-11,
Class 1A-12, Class 1A-PO, Class 1A-WIO, Class A-R, Class 1M, Class 1B-1, Class
1B-2 (collectively, the "Group 1 Offered Certificates"), and Class 1B-3, Class
1B-4 and Class 1B-5 (collectively, the "Group 1 Private Certificates" and
together, with the Group 1 Offered Certificates, the "Group 1 Certificates") and
the second consisting of Class 2A, Class 2M, Class 2B-1 and Class 2B-2
(collectively, the "Group 2 Offered Certificates"), and Class 2B-3, Class 2B-4
and Class 2B-5 (collectively, the "Group 2 Private Certificates" and together,
with the Group 2 Offered Certificates, the "Group 2 Certificates") (together,
the Group 1 Certificates and the Group 2 Certificates, are sometimes
collectively referred to herein as the "Certificates").

           The Depositor has sold the Group 1 Offered Certificates to First
Union Capital Markets, a division of Wheat First Securities, Inc. ("First Union
Capital Markets"), and Salomon Brothers, Inc. ("Salomon Brothers" and, together
with First Union Capital Markets, the "Group 1 Underwriters") pursuant to the
Underwriting Agreement, dated July 24, 1998

(the "Group 1 Underwriting Agreement") among the Depositor, the Seller and the
Group 1 Underwriters.

           The Depositor has sold the Group 2 Offered Certificates to First
Union Capital Markets and PaineWebber Incorporated ("PaineWebber" and, together
with First Union Capital Markets, the "Group 2 Underwriters") pursuant to the
Underwriting Agreement, dated July 24, 1998 (the "Group 2 Underwriting
Agreement") among the Depositor, the Seller and the Group 2 Underwriters.

           The Certificates represent the entire undivided beneficial interest
in the assets of the Trust. The assets of the Trust will consist primarily of
the Mortgage Loans. Terms not defined herein shall have the meanings set forth
in the Pooling and Servicing Agreement.

           In arriving at the opinions expressed below, we have examined such
documents and records as we have deem appropriate, including the following:

           1.         Signed copies of the Group 1 and Group 2 Underwriting
                      Agreements.

           2.         The registration statement (No. 333-3574) of the Depositor
                      on form S-3 on file with the Securities and Exchange
                      Commission (the "Commission"). Such registration statement
                      on the date it was declared effective herein referred to
                      as the "Registration Statement".

           3.         The Prospectus, dated July 24, 1998 (the "Base
                      Prospectus"), as supplemented by the Prospectus Supplement
                      dated July 24, 1998, relating to the Offered Certificates
                      (the "Prospectus Supplement") (such Base Prospectus, as so
                      supplemented by the Prospectus Supplement, the
                      "Prospectus").

           4.         A signed copy of the Purchase Agreement.

           5.         A signed copy of the Pooling and Servicing Agreement.

           6.         Specimens of the Certificates.

           As to any facts material to the following opinions which we did not
independently establish or verify, we have relied upon statements and
representations of the responsible officers and other representations of the
Depositor and of public officials and agencies.

           Based upon the foregoing and consideration of such other matters as
we have deemed appropriate, we are of the opinion that the statements in the
Base Prospectus under the headings "SUMMARY OF TERMS--Certain Federal Income Tax
Consequences" and "--ERISA Considerations," "CERTAIN LEGAL ASPECTS OF THE
MORTGAGE LOANS," "ERISA CONSIDERATIONS" and "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES," and

the statements in the Prospectus Supplement under the headings "SUMMARY OF TERMS
OF THE OFFERED CERTIFICATES--Certain Federal Income Tax Consequences" and
"--ERISA Considerations," "CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS,"
"CERTAIN FEDERAL INCOME TAX CONSEQUENCES" and "ERISA CONSIDERATIONS," to the
extent that they constitute matters of federal law or legal conclusions with
respect thereto, have been reviewed by us and are correct in all material
respects with respect to those consequences or aspects that are discussed.

           In giving the foregoing opinions, we express no opinion as to the
laws of any jurisdiction other than the State of North Carolina and the federal
laws of the United States of America. We hereby consent to the filing of this
opinion as an exhibit to the Registration Statement and to the use of our name
wherever appearing in the Registration Statement and the Prospectus. In giving
such consent, we do not consider that we are "experts," within the meaning of
the term as used in the Securities Act of 1933, as amended, or the rules and
regulations of the Commission issued thereunder, with respect to any part of the
Registration Statement, including this opinion as an exhibit or otherwise.

                                Sincerely yours,

                                KILPATRICK STOCKTON LLP

                                /s/ Kilpatrick Stockton LLP
