INDEPENDENT AUDITORS' REPORT
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 "Fund") for the year ended
October 31, 1998 (on which we have issued our report
dated December 11, 1998), we considered its internal
control, including control activities 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, and not to provide
assurance on the Fund's internal control.
The management of the Fund is responsible for
establishing and maintaining internal control. In
fulfilling this responsibility, estimates and judgments
by management are required to assess the expected
benefits and related costs of controls. Generally,
controls that are relevant to an audit pertain to the
entity's objective of preparing financial statements
for external purposes that are fairly presented in
conformity with generally accepted accounting
principles. Those controls include the safeguarding of
assets against unauthorized acquisition, use, or
disposition.
Because of inherent limitations in any internal
control, errors or fraud may occur and not be detected.
Also, projection of any evaluation of internal control
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 Fund's internal control would
not necessarily disclose all matters in internal
control 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 one or
more of the internal control components does not reduce
to a relatively low level the risk that errors or fraud
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 Fund's
internal control and its operation, including controls
for safeguarding securities, that we consider to be
material weaknesses as defined above as of October 31,
1998.
This report is intended solely for the information and
use of management, the Board of Directors of The
BlackRock New York Investment Quality Municipal Trust
Inc. and the Securities and Exchange Commission.
December 11, 1998
