                           EXPLANATORY NOTE
                           ----------------

Diversified Historic Investors IV  (the "Registrant")  is  filing
the  following  Annual Report on Form 10-K for the  period  ended
December 31, 2003 containing  consolidated financial statements.

On July 11th, 2005 the Securities and Exchange Commission ("SEC")
notified   the  Registrant  of  its  non-compliance  in   meeting
reporting  requirements  under Section  13(a)  or  15(d)  of  the
Securities  and Exchange Act of 1934. The Registrant's  inability
to  meet its reporting requirements is due to the dissolution  of
its  former auditor, Gross Kreger & Passio, LLC. This  event  was
discussed in Item 4.01 of the Registrant's Form 8-K filed on June
27th, 2005.

The Registrant engaged a new firm, Russell Bedford Stefanou
Mirchandani, LLP to audit and review the Registrants' outstanding
consolidated financial statements.  Accordingly, the Company is
re-filing the Original Filing in its entirety with an updated
Item 8 and 14 of the Original Filing.  The Company has not made
any other changes to the Original Filing.   This Amendment No. 1
on Form 10-K/A continues to speak as of the date of the Original
Filing, and the Company has not updated the disclosures contained
therein to reflect any events that occurred at a later date.

                                ------

Item 1.   Business
          --------

          a. General Development of Business

              Diversified Historic Investors IV ("Registrant") is
a  limited partnership formed in 1987 under Pennsylvania law.  As
of December 31, 2003, Registrant had outstanding 8,285.7 units of
limited partnership interest (the "Units").

              Registrant is presently in its operating stage.  It
originally  owned  three  properties or interests  therein.   One
property  has  been sold.  It currently owns two properties.  See
Item  2.  Properties, for a description thereof. For a discussion
of  the  operations  of  the Registrant, See  Part  II,  Item  7.
Management's  Discussion and Analysis of Financial Condition  and
Results of Operations.


          b. Financial Information about Industry Segments

             The Registrant operates in one industry segment.

          c. Narrative Description of Business

             Registrant is in the business of operating, holding,
selling,  exchanging  and  otherwise dealing  in  and  with  real
properties  containing improvements that are "Certified  Historic
Structures," as such term is defined in the Internal Revenue Code
(the   "Code")  for  use  as  apartments,  offices,  hotels   and
commercial  spaces,  or any combination thereof,  or  low  income
housing eligible for the tax credit provided by Section 42 of the
Code, and such other uses as the Registrant's general partner may
deem appropriate.

             Since the Registrant's inception, all the properties
acquired  by  the  Registrant, or the subsidiary partnerships  in
which  it  has an interest, have been rehabilitated and certified
as  historic structures and have received the related  investment
tax  credit.   All the properties are held for rental operations.
At  this time it is anticipated that the two remaining properties
will continue to be held for this purpose until such time as real
property values in
  the  areas  in  which  these properties are  located  begin  to
increase.   At  that  time, the Registrant will  re-evaluate  its
investment strategy regarding the properties.

              As  of  December  31,  2003, Registrant  owned  two
properties,  one each located in North Carolina and Pennsylvania.
In  total,  the  properties contain 22 apartment  units.   As  of
December 31, 2003, 21 of the apartment units were under lease  at
monthly rental rates ranging from $413 to $1,150.  Rental of  the
apartments  is  not  expected  to be  seasonal.   For  a  further
discussion of the properties, see Item 2. Properties.

              The  Registrant is affected by and subject  to  the
general  competitive  conditions of the residential  real  estate
industry.  As a result of the overbuilding that occurred  in  the
1980's,  the  competition for residential tenants  in  the  local
markets   where  the  Registrant's  properties  are  located   is
generally  strong.  The  properties  held  for  rental   by   the
Registrant  are  located  in the Old City  Historic  District  in
Philadelphia, Pennsylvania and Concord, North Carolina.  In  both
areas   there   are   several  similar   historically   certified
rehabilitated buildings. However, there is no organization  which
holds  a  dominant position in the residential housing market  in
either   of  the  geographic  areas  in  which  the  Registrant's
properties  are located. The apartment market remains  stable  in
both areas and new construction remains virtually nonexistent  in
Concord,  North Carolina although the availability  of  favorable
home financing has placed pressure on the rental tenant base. The
Registrant is able to raise rental rates and stay fully  occupied
in  the  Philadelphia property but at the same time,  competitive
pressure exists from other buildings in the Old City area and the
emerging Northern Liberties neighborhood.

               Registrant   has   no   employees.    Registrant's
activities  are overseen by Brandywine Construction & Management,
Inc., ("BCMI"), a real estate management firm.

Operations and Export Sales.

              See  Item 8. Financial Statements and Supplementary
Data.


Item 2.   Properties
          ----------

              As  of  December  31,  2003, Registrant  owned  two
properties, or interests therein, as follows:

           a. The Brass Works - consists of 12 apartments located
at 231-237 Race Street, Philadelphia, Pennsylvania.  In May 1987,
Registrant acquired and rehabilitated the Property for $1,200,000
($111 per square foot)("sf") funded by its equity contribution.

              The  property is managed by BCMI.  At December  31,
2003,  11  of  the  apartment units were under lease  (92%)  with
monthly  rents  ranging  from $875 to  $1,150.   All  leases  are
renewable,  one-year leases. The occupancy for the previous  four
years was 92% for 2002, 99% for 2001, 100% for 2000 and 100%  for
1999.  The  monthly rental range for the previous four years  was
$850  to $1,125 during 2002, $650 to $1,095 during 2001, $650  to
$925  during  2000,  and $690 to $875 during  1999.  The  monthly
rental  range increased to its present level due to the  increase
in  popularity of the Old City neighborhood in which the property
is located, and the sustained ability of the property to be fully
occupied (other than transitory vacancies) at increasing  monthly
rental  rates.  For tax purposes, the building and  land  have  a
federal  tax  basis of $1,135,324 and the building is depreciated
using  the straight-line method with a useful life of 27.5 years.
The  annual real estate taxes are $12,694, which is based  on  an
assessed value of $153,600 taxed at a rate of $82.64 per $100. No
one  tenant occupies ten percent or more of the building.  It  is
the opinion of the management of the Registrant that the property
is adequately covered by insurance.

           b.  Locke  Mill  Plaza - consists  of  10  residential
apartment  condominium  units in a 169 condominium  unit  project
located  on  Buffalo  Avenue at Union Street  in  Concord,  North
Carolina.  In  November 1988, Registrant acquired the  units  for
$665,000 funded by its equity contribution.

             The property is managed by BCMI.  As of December 31,
2003, 10 units were under lease (100%) with monthly rates ranging
from $413 to $560. All leases are renewable, one-year leases. The
occupancy as of year end for the previous four years was 80%  for
2002,  100% for 2001, 60% for 2000, and 80% for 1999. The monthly
rental range was $500 to $560 for 2002, 2001 and 2000 and $525 to
$560  for 1999.  For tax purposes, the building and land  have  a
federal  tax  basis of $664,252 and the building  is  depreciated
using  the straight-line method with a useful life of 27.5 years.
The  annual  real estate taxes are $4,803 which is  based  on  an
assessed value of $475,550 taxed at a rate of $1.01 per $100.  No
one  tenant occupies ten percent or more of the building.  It  is
the opinion of the management of the Registrant that the property
is adequately covered by insurance.

Item 3.   Legal Proceedings
          -----------------


          To the best of its knowledge, Registrant is not a party
to,  nor  is  any  of its property the subject  of,  any  pending
material legal proceeding.

Item 4.   Submission of Matters to a Vote of Security Holders
          ---------------------------------------------------

          No matter was submitted during the fiscal years covered
by this report to a vote of security holders.

Item  5.    Market  for  Registrant's Common Equity  and  Related
            Stockholder Matters
            -----------------------------------------------------

           a.  There is no established public trading market  for
the  Units.  Registrant does not anticipate any such market  will
develop.   Trading  in  the Units occurs solely  through  private
transactions. The Registrant is not aware of the prices at  which
trades  occur. Registrant's records indicate that 33  units  were
sold or exchanged in 2003.

           b.  As  of December 31, 2003, there were 1,013  record
holders of Units.

           c.   Registrant did not declare any cash dividends in 2003
or 2002.

Item 7.   Management's Discussion and Analysis of Financial
          Conditions and Results of Operations
          -------------------------------------------------

     (1)  Liquidity

            At   December  31,  2003,  Registrant  had  cash   of
approximately $249,100.  The Registrant expects that those  funds
plus the cash generated from operations at each property will  be
sufficient to fund the operating expenses of the properties.

          As of December 31, 2003, Registrant had restricted cash
of  $26,761  consisting  primarily  of  funds  held  as  security
deposits,  replacement reserves, escrows for taxes and insurance.
As a consequence of these restrictions as to use, Registrant does
not deem these funds to be a source of liquidity.

     (2)  Capital Resources

            Any   capital   expenditures  needed  are   generally
replacement  items and are funded out of cash from operations  or
replacement reserves, if any. The Registrant is not aware of  any
factors  which would cause historical capital expenditure  levels
not  to  be indicative of capital requirements in the future  and
accordingly,  does  not  believe that  it  will  have  to  commit
material  resources  to capital investments for  the  foreseeable
future.

     (3)  Results of Operations

          During 2003, Registrant incurred a net loss of $126,413
($15.10  per  limited partnership unit) compared  to  a  loss  of
$116,040 ($13.86 per limited partnership unit) in 2002 and a loss
of $69,298 ($8.28 per limited partnership unit) in 2001.


           Rental income was $208,819 in 2003, $199,638 in  2002,
and $203,679 in 2001. The increase in rental income from 2002  to
2003  is  due to an increase in average occupancy at Brass  Works
(91%  to  96%), partially offset by a decrease in average  rental
rates  at Locke Mill. The decrease in rental income from 2001  to
2002 is due to a decrease in average occupancy at Locke Mill (88%
to  80%)  and a decrease in average occupancy at the Brass  Works
(99% to 91%).

          Interest income was $2,792 in 2003, $5,604 in 2002, and
$8,944 in 2001. The decrease in interest income from both 2002 to
2003  and  from  2001  to 2002 is due to a  decrease  in  average
invested cash balances and a decrease in interest rates on  money
market accounts.

            Rental  operations  expense  was  $152,112  in  2003,
$151,436  in 2002, and $117,380 in 2001. The increase  in  rental
operations  expense from 2002 to 2003 is due to  an  increase  in
insurance  expense at Brass Works and Locke Mill, an increase  in
maintenance expense and utilities expense at Brass Works  and  an
increase in condominium fees at Locke Mill, partially offset by a
decrease  in maintenance expense and wages and salaries at  Locke
Mill.  The increase in insurance expense at Brass Works and Locke
Mill  is  due  to  insurance market conditions. The  increase  in
maintenance  expense  at Brass Works is due  to  an  increase  in
maintenance service and snow removal.  The increase in  utilities
expense  at  Brass  Works is due to an increase  in  electricity,
water  and sewer charges.  The increase in condominium  fees  are
due  to an increase in budgeted operating expenses at Locke Mill.
The  decrease in maintenance expense at Locke Mill is  due  to  a
decrease  in  apartment painting and maintenance  supplies.   The
decrease in wages and salaries expense at Locke Mill is due to  a
decrease  in maintenance wages. The increase in rental operations
expense  from  2001  to 2002 is due to an increase  in  insurance
expense at Brass Works and Locke Mill, an increase in maintenance
expense, leasing commissions and real estate tax expense  at  the
Brass   Works,  and  an  increase  in  wages  and  salaries   and
condominium  fees,  partially offset by  a  decrease  in  leasing
commissions at Locke Mill. The increase in insurance  expense  at
the  Brass  Works  and  Locke Mill is  due  to  insurance  market
conditions.  The  increase  in maintenance  expense  and  leasing
commissions at the Brass Works is due to an increase in  turnover
of  apartment units. The increase in real estate tax  expense  at
the Brass Works is due to an increase in the property's appraised
value  on  which the taxes are based. The increase in  wages  and
salaries  expense  at  Locke  Mill  is  due  to  an  increase  in
maintenance wages. The increase in condominium fees are due to an
increase  in  budgeted  operating expenses  at  Locke  Mill.  The
decrease  in  leasing  commissions at Locke  Mill  is  due  to  a
decrease in turnover of apartment units.

          Bad debt expense was $15,823 in 2003 and $2,861 in 2002
due  to  the  write-off of tenant accounts receivable  that  were
deemed uncollectible.

          General and administrative expense was $72,000 in 2003,
2002 and 2001.
           During  2003,  a  loss  of approximately  $20,000  was
incurred at the Registrants two properties compared to a loss  of
approximately $11,000 during 2002, and income of $36,000 in 2001.

           Risk
           ------------------------------------------------------

                  Independent Auditor's Report

To the Partners of
Diversified Historic Investors IV

We  have  audited the accompanying consolidated balance sheet  of
Diversified   Historic  Investors  IV  (a  Pennsylvania   Limited
Partnership)  and subsidiaries as of December 31,  2003  and  the
related statements of operations, changes in partners' equity and
cash   flows  for  the  year  ended  December  31,  2003.   These
consolidated financial statements are the responsibility  of  the
Partnership's  management. Our responsibility is  to  express  an
opinion on these consolidated financial statements based  on  our
audit.

We conducted our audit in accordance with standards of the Public
Company  Accounting Oversight Board (United States  of  America).
Those  standards require that we plan and perform  the  audit  to
obtain   reasonable  assurance  about  whether  the  consolidated
financial statements are free of material misstatement.  An audit
includes  examining,  on  a test basis, evidence  supporting  the
amounts and disclosures in the consolidated financial statements.
An  audit also includes assessing the accounting principles  used
and  significant  estimates  made  by  management,  as  well   as
evaluating  the  overall  financial statement  presentation.   We
believe  that  our  audit  provides a reasonable  basis  for  our
opinion.

In our opinion, the consolidated financial statements referred to
above  present  fairly, in all material respects,  the  financial
position of Diversified Historic Investors IV as of December  31,
2003  and  the results of operations and cash flows for the  year
ended  December 31, 2003 in conformity with accounting principles
generally accepted in the United States.

Our audits were made for the purpose of forming an opinion on the
basic  financial  statements taken as a whole.  The  Schedule  of
Real  Estate and Accumulated Depreciation on page 23 is presented
for  the  purposes of additional analysis and is not  a  required
part  of  the  basic financial statements.  Such information  has
been subjected to the auditing procedures applied in the audit of
the  basic  financial statements and, in our opinion,  is  fairly
stated  in  all  material  respects  in  relation  to  the  basic
financial statements taken as a whole.

                   DIVERSIFIED HISTORIC INVESTORS IV
                   ---------------------------------
                        (a limited partnership)

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              ------------------------------------------

NOTE A - ORGANIZATION
---------------------

Diversified Historic Investors IV (the "Partnership") was  formed
in  January 1987, with Dover Historic Advisors III as the General
Partner  and  DHP,  Inc.,  (formerly Dover  Historic  Properties,
Inc.,)  as the limited partner.  Upon the admission of additional
limited partners, the initial limited partner withdrew.

The  Partnership was formed to acquire, rehabilitate, and  manage
real  properties  which  are  certified  historic  structures  as
defined in the Internal Revenue Code (the "Code"), or which  were
eligible for designation as such, utilizing the net proceeds from
the  sale  of  limited  partnership units.   Any  rehabilitations
undertaken by the Partnership were done with a view to  obtaining
certification    of   expenditures   therefor    as    "qualified
rehabilitation expenditures" as defined in the Code.



NOTE B - SIGNIFICANT ACCOUNTING POLICIES
----------------------------------------

A  summary of the significant accounting policies applied in  the
preparation of the accompanying consolidated financial statements
follows:

1.   Principles of Consolidation

The   accompanying  consolidated  financial  statements  of   the
Partnership include the accounts of one subsidiary partnership in
which   the   Partnership  had  a  controlling   interest,   with
appropriate  elimination  of inter-partnership  transactions  and
balances.   These  financial statements reflect  all  adjustments
(consisting only of normal recurring adjustments) which,  in  the
opinion of the Partnership's General Partner, are necessary for a
fair statement of the results for the year.

2.   Costs of Issuance

Costs  incurred  in  connection with the  offering  and  sale  of
limited  partnership units were charged against partners'  equity
as incurred.

3.   Depreciation

Depreciation is computed using the straight-line method over  the
estimated useful lives of the assets.  Buildings and improvements
are  depreciated  over 25 years and furniture and  fixtures  over
five years.


4.   Net Loss Per Limited Partnership Unit

The net loss per limited partnership interest (a "Unit") is based
on  the  weighted  average  number of limited  partnership  Units
outstanding during the period (8,285.7 Units in 2003,  2002,  and
2001).

5.   Income Taxes

Federal  and  state  income taxes are payable by  the  individual
partners;  therefore, no provision or liability for income  taxes
is reflected in the financial statements.

6.   Cash and Cash Equivalents

The Partnership considers all highly liquid investments purchased
with a maturity of less than three months to be cash equivalents.

7.   Concentration of Credit Risk

Financial  instruments which potentially subject the  Partnership
to  concentration of credit risk consist principally of cash  and
cash  equivalents.  The Partnership maintains its cash  and  cash
equivalents  in  financial institutions insured  by  the  Federal
Deposit  Insurance  Corporation up to $100,000  per  company.  At
December  31,  2003, uninsured funds held at one institution  are
approximately $200,000.

8.   Restricted Cash

Restricted  cash  includes  amounts  held  for  tenant   security
deposits,  real estate tax reserves and other cash restricted  as
to use.

9.   Revenue Recognition

Revenues  are  recognized  when rental  payments  are  due  on  a
straight-line  basis.  Rental payments received  in  advance  are
deferred until earned.

10.  Rental Properties

Rental properties are stated at cost.  A provision for impairment
of value is recorded when a decline in the value of a property is
determined to be other than temporary as a result of one or  more
of  the following: (1) a property is offered for sale at a  price
below  its  current  carrying value; (2) a  mortgage  loan  on  a
property   has  significant  balloon  payments  due  within   the
foreseeable  future  which  the Partnership  does  not  have  the
resources  to meet, and anticipates it will be unable  to  obtain
replacement financing or debt modification sufficient to allow it
to  continue  to  hold the property over a reasonable  period  of
time;  (3)  a  property  has been, and is expected  to  continue,
generating significant operating deficits and the Partnership  is
unable  or  unwilling  to  sustain such deficits,  and  has  been
unable,  or  anticipates  it  will  be  unable,  to  obtain  debt
modification, financing or refinancing sufficient to allow it  to
continue to hold the property for a reasonable period of time, or
(4)  a  property's  value  has  declined  based  on  management's
expectations  with respect to projected future  operational  cash
flows and prevailing economic conditions.  An impairment loss  is
indicated  when  the  undiscounted sum of estimated  future  cash
flows  from  an  asset, including estimated sales  proceeds,  and
assuming a reasonable period of ownership up to 5 years, is  less
than  the  carrying amount of the asset. The impairment  loss  is
measured  as the difference between the estimated fair value  and
the  carrying  amount of the asset. In the absence of  the  above
circumstances,  properties and improvements are stated  at  cost.
An analysis is done on an annual basis at December 31.

11.  Use of Estimates

The  preparation  of the financial statements in conformity  with
generally  accepted accounting principles requires management  to
make  estimates and assumptions that affect the amounts  reported
in  the  financial  statements  and  accompanying  notes.  Actual
results could differ from those estimates.


NOTE C - PARTNERSHIP AGREEMENT
------------------------------

The  significant terms of the amended and restated  Agreement  of
Limited  Partnership (the "Agreement"), as  they  relate  to  the
financial statements, follow:

The  Agreement  provides that beginning  with  the  date  of  the
admission  of  subscribers as limited partners, all distributable
cash from operations (as defined) will be distributed 90% to  the
limited partners and 10% to the General Partner.

All  distributable cash from sales or dispositions  (as  defined)
will  be distributed to the limited partners up to their original
capital  contributions plus an amount equal  to  six  percent  of
their  original capital contributions per annum on  a  cumulative
basis,  less  the  sum  of  all  prior  distributions  to   them;
thereafter,  after  receipt  by  the  General  Partner   or   its
affiliates  of  any  accrued  but unpaid  real  estate  brokerage
commissions,  the distributable cash will be distributed  15%  to
the General Partner and 85% to the limited partners.

Net  income  or  loss  from  operations  of  the  Partnership  is
allocated  1%  percent  to the General Partner  and  99%  to  the
limited partners.


NOTE D - ACQUISITIONS
---------------------

The   Partnership  acquired  two  properties  and   one   general
partnership  interest in a partnership owning  a  third  property
during  the  period from May 1987 to November 1988, as  discussed
below.

In  May  1987,  the Partnership purchased a three-story  building
located  in Philadelphia, Pennsylvania consisting of 12 apartment
units.   The  cost to acquire and rehabilitate this property  was
approximately $1,200,000.

In  July  1987, the Partnership was admitted, with a 95%  general
partnership interest, to a Pennsylvania general partnership which
owned a building located in New Orleans, Louisiana consisting  of
61  apartment units, for cash contributions of $4,620,000.  As of
December 31, 1996, all of the units were sold. As of December 31,
1997,  the  mortgages  from  the  seller  provided  financing  in
connection with the sale of the units were sold.

In November 1988, the Partnership purchased 10 condominium units,
in a building located in Concord, North Carolina, for $665,000.

Item  9.    Changes  in  and Disagreements  with  Accountants  on
Accounting and Financial Disclosure
-----------------------------------------------------------------

          None.


Item 9A.   Controls and Procedures
----------------------------------

          We maintain disclosure controls and procedures that are
     designed to ensure that information required to be disclosed
     in  our Securities Exchange Act of 1934 reports is recorded,
     processed,   summarized  and  that   such   information   is
     accumulated  and  communicated to our management,  including
     our  managing  partner's  principal  executive  officer  and
     principal financial officer, as appropriate, to allow timely
     decisions  regarding required disclosure.  In designing  and
     evaluating  the  disclosure  controls  and  procedures,  our
     management  recognized that any controls and procedures,  no
     matter  how  well  designed and operated, can  provide  only
     reasonable  assurance  of  achieving  the  desired   control
     objectives,  and our management necessarily was required  to
     apply   its   judgment   in  evaluating   the   cost-benefit
     relationship of possible controls and procedures.

          Under   the   supervision  of  our  managing  partner's
     principal executive officer and principal financial  officer
     we  have  carried out an evaluation of the effectiveness  of
     our adopted disclosure controls and procedures as of the end
     of  the  period  covered by this report.   Based  upon  that
     evaluation,  our managing partner's president and  treasurer
     concluded  that  our disclosure controls and procedures  are
     effective.

          There  have been no significant changes in our internal
     controls   over  financial  reporting  that  has  materially
     affected, or is reasonably likely to materially affect,  our
     internal  control over financial reporting during  our  most
     recent fiscal quarter.
