SUB - ITEM 77J
Reclassification of Capital Accounts
The Trust accounts and reports for permanent
differences between financial and tax reporting
in accordance with the American Institute of
Certified Public Accountants' Statement of
Position 93-2: Determination, Disclosure and
Financial Statement Presentation of Income,
Capital Gain and Return of Capital Distributions
by Investment Companies. The effect of applying
this statement for the year ended October 31,
1997 was to increase accumulated net realized
loss and increase undistributed net investment
income by $1,544. Net investment income, net
realized gains and net assets were not affected

To the Shareholders and Board of Directors of
The BlackRock New York Investment Quality
Municipal Trust, Inc.:
In planning and performing our audit of the
financial statements of The BlackRock New York
Investment Quality Municipal Trust, Inc. (the
"Trust") for the year ended October 31, 1997 (on
which we have issued our report dated December
12, 1997), we considered its internal control
structure, including procedures for safeguarding
securities, in order to determine our auditing
procedures for the purpose of expressing our
opinion on the financial statements and to
comply with the requirements of Form N-SAR, not
to provide assurance on the internal control
structure.
The management of the Trust is responsible for
establishing and maintaining an internal control
structure. In fulfilling this responsibility,
estimates and judgments by management are
required to assess the expected benefits and
related costs of internal control structure
policies and procedures. Two of the objectives
of an internal control structure are to provide
management with reasonable, but not absolute,
assurance that assets are safeguarded against
loss from unauthorized use or disposition and
that transactions are executed in accordance
with management's authorization and recorded
properly to permit preparation of financial
statements in conformity with generally accepted
accounting principles.
Because of inherent limitations in any internal
control structure, errors or irregularities may
occur and not be detected. Also, projection of
any evaluation of the structure to future
periods is subject to the risk that it may
become inadequate because of changes in
conditions or that the effectiveness of the
design and operation may deteriorate.
Our consideration of the internal control
structure would not necessarily disclose all
matters in the internal control structure that
might be material weaknesses under standards
established by the American Institute of
Certified Public Accountants. A material
weakness is a condition in which the design or
operation of the specific internal control
structure elements does not reduce to a
relatively low level the risk that errors or
irregularities in amounts that would be material
in relation to the financial statements being
audited may occur and not be detected within a
timely period by employees in the normal course
of performing their assigned functions.
However, we noted no matters involving the
internal control structure, including procedures
for safeguarding securities, that we consider to
be material weaknesses as defined above as of
October 31, 1997.
This report is intended solely for the
information and use of management and the
Securities and Exchange Commission.
