                         Notes to Financial Statements
                                 June 30, 1995
                                  (Unaudited)

NOTE 1.
------

McNeil  Real  Estate  Fund  XX,  L.P.  (the  "Partnership"),  formerly  known as
Southmark  Income  Investors,  Ltd., was organized on July 19, 1984 as a limited
partnership  under the  provisions of the  California  Revised  Uniform  Limited
Partnership Act. The general partner of the Partnership is McNeil Partners, L.P.
(the "General Partner"), a Delaware limited partnership,  an affiliate of Robert
A. McNeil  ("McNeil").  The principal  place of business for the Partnership and
the General Partner is 13760 Noel Road, Suite 700, Dallas, Texas 75240.

In the opinion of management,  the financial  statements reflect all adjustments
necessary for a fair  presentation of the Partnership's  financial  position and
results  of  operations.  All  adjustments  were of a normal  recurring  nature.
However,  the results of  operations  for the six months ended June 30, 1995 are
not  necessarily  indicative  of the results to be expected  for the year ending
December 31, 1995.

NOTE 2.
------

The  financial  statements  should  be read in  conjunction  with the  financial
statements  contained in the  Partnership's  Annual  Report on Form 10-K for the
year  ended  December  31,  1994,  and the  notes  thereto,  as  filed  with the
Securities and Exchange  Commission,  which is available upon request by writing
to McNeil Real Estate Fund XX, L.P.,  c/o McNeil Real Estate  Management,  Inc.,
Investor Services, 13760 Noel Road, Suite 700, Dallas, Texas 75240.

NOTE 3.
------

Certain prior period  amounts have been  reclassified  to conform to the current
period presentation.

NOTE 4.
------

The  Partnership  pays property  management fees equal to 5% of the gross rental
receipts for its properties to McNeil Real Estate Management,  Inc.  ("McREMI"),
an affiliate of the General Partner, for providing property management services.

The  Partnership  reimburses  McREMI  for  its  costs,  including  overhead,  of
administering the Partnership's affairs.

The  Partnership  is paying an asset  management  fee  which is  payable  to the
General  Partner.  Through 1999, the asset management fee is calculated as 1% of
the  Partnership's  tangible asset value.  Tangible asset value is determined by
using the greater of (i) an amount calculated by applying a capitalization  rate
of 9% to the annualized net operating income of each property or (ii) a value of
$10,000 per  apartment  unit to arrive at the property  tangible  asset value or
(iii) on 1130  Sacramento,  the net  book  value of the  property  is used.  The
property  tangible  asset  value is then  added to the book  value of all  other
assets excluding intangible items.

The fee percentage decreases subsequent to 1999.

Compensation  and  reimbursements  paid to or  accrued  for the  benefit  of the
General Partner and its affiliates are as follows:


                                                                                  Six Months Ended

In May 1994,  the Idlewood  Nursing Home mortgage loan  investment was modified,
extending  the maturity date to March 1999 and reducing the interest rate on the
loan from 12% to 8.5%.  Unpaid  accrued  interest of $82,566 for  November  1993
through February 1994 was added to the principal balance at March 1, 1994 and is
no longer considered  interest.  Monthly payments of principal and interest were
reduced from $25,067 to $17,286  beginning  April 1, 1994. In February 1995, the
Idlewood Nursing Home mortgage loan investment was again modified.  The interest
rate remained at 8.5% and the maturity date was changed to February 1, 1998. The
borrower paid the Partnership  $33,200 in cash at the date of  modification  and
the  monthly  payments  on the loan  were  changed  such  that  cash  flow  from
operations of the property, with a minimum payment of $9,130, are due monthly.

In February  1995,  the  Lakeland  Nursing Home  mortgage  loan  investment  was
modified  extending the maturity date to February 1, 1998. The interest rate and
monthly  payment amount remain the same.  The borrower paid a $25,941  extension
fee which the Partnership recorded as a deferred gain.


ITEM 2.       MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
------        ---------------------------------------------------------------
              RESULTS OF OPERATIONS
              ---------------------

FINANCIAL CONDITION
-------------------

There has been no  significant  change in the  operations  of  Sterling  Springs
Apartments or 1130 Sacramento Condominiums since December 31, 1994.

The Partnership  reported net income of $70,240 for the first six months of 1995
as  compared  to  $143,363  for the same  period in 1994.  Revenues in 1995 were
$944,597 as compared to $912,710 in 1994,  while expenses  increased to $874,357
from $769,347.

Net cash provided by operating  activities was $229,460 for the six months ended
June 30,  1995, a change from the  $169,884  provided  during the same six month
period in 1994. The Partnership expended $32,555 for capital improvements,  made
$23,799 in  principal  payments on its  mortgage  note  payable,  and  collected
$81,958 of  principal  on mortgage  loan  investments.  After  distributions  of
$250,001 to the limited partners,  cash and cash equivalents  totaled $3,739,083
at June 30,  1995,  a net  increase of $5,063  from the balance at December  31,
1994.

RESULTS OF OPERATIONS
---------------------

Revenue:

Total  revenue  increased  by $27,250  and  $31,887  for the three and six month
periods  ended June 30, 1995,  respectively,  as compared to the same periods in
1994.  The increase was due to an increase in rental revenue which was partially
offset  by a  decrease  in  interest  income on  mortgage  loan  investments  as
discussed below.

Rental revenue for the three and six month periods ended June 30, 1995 increased
by $53,169 and $109,702,  respectively, as compared to the same periods in 1994.
The increase  was mainly due to an increase in rental rates at Sterling  Springs
Apartments in February 1995. Also contributing to the increase in rental revenue
was the increase in the occupancy rate at 1130  Sacramento  from 50% at June 30,
1994 to 100% at June 30, 1995.

Interest income on mortgage loan  investments  decreased by $49,050 and $122,451
for the three and six months ended June 30, 1995,  respectively,  as compared to
the same periods in 1994 due to the  modification  of the Idlewood  Nursing Home
mortgage  loan  investment in February 1995 (See Item 1 - Note 5). In accordance
with  Statement  of  Financial  Accounting  Standards  No.  114  "Accounting  by
Creditors for Impairment of a Loan" ("SFAS 114"), which the Partnership  adopted
in 1994,  the  Partnership  has  ceased  accruing  interest  on the loan and all
payments received are recorded as a reduction of principal.

Other  interest  income  earned  on  short-term  investments  of cash  and  cash
equivalents increased by $23,132 and $44,636 for the three and six month periods
ended June 30,  1995,  respectively,  as compared to the  respective  periods in
1994.  The  increase  was mainly due to an increase in interest  rates earned on
invested cash during the first six months of 1995.

Expenses:

Total expenses for the three and six month periods ended June 30, 1995 increased
by $46,629 and $105,010,  respectively, as compared to the respective periods in
1994.

Depreciation  expense  increased  by $9,321  and  $27,787  for the three and six
months  ended June 30,  1995,  respectively,  as compared to the same periods in
1994.  The increase was  primarily  due to the addition of  depreciable  capital
improvements at Sterling Springs Apartments and 1130 Sacramento Condominiums.

Property  taxes for the three and six months  ended June 30, 1995  increased  by
$6,159 and $15,576,  respectively,  as compared to the same periods in 1994. The
increase  was mainly due to an increase in the  property  tax  liability at 1130
Sacramento  due to an increase in the  assessed  taxable  value of the  property
after its completion in early 1994.

Personnel  costs  increased  by $4,591 and  $18,371 for the three and six months
ended June 30,  1995,  respectively,  as compared to the  respective  periods in
1994.  The increase  was due to an increase in bonuses paid at Sterling  Springs
and 1130 Sacramento, the result of an increase in the overall performance of the
properties in the first quarter of 1995.

Property  management  fees increased by $3,149 in the three months and by $5,782
in the six months ended June 30, 1995, in relation to the comparable  periods in
1994, due to an increase in gross rental receipts,  on which the fees are based,
at 1130 Sacramento Condominiums and Sterling Springs Apartments.

Other property  operating expenses increased by $8,114 and $13,854 for the first
three and six months of 1995,  respectively,  as compared to the same periods in
1994. The increase was mainly due to an increase in property  insurance costs in
1995.

General and administrative expenses increased by $8,941 and $9,814 for the three
and six month  period  ended June 30,  1995,  respectively,  as  compared to the
respective  periods in 1994.  The increase was due to an increase in legal fees,
the result of the Idlewood and Lakeland note modifications.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

The Partnership  generated  $229,460 through operating  activities for the first
six months of 1995 as compared to $169,884 for the first six months of 1994. The
increase  in 1995 was mainly due to an increase in cash  received  from  tenants
(see discussion of increase in rental revenue above).

The Partnership  expended  $32,555 and $110,174 for capital  improvements to its
properties in the first six months of 1995 and 1994, respectively. 1994 includes
improvements  to 1130 Sacramento for which  construction  was completed early in
1994.

The Partnership  collected $81,958 of principal on its mortgage loan investments
in the first six months of 1995 as  compared  to $17,552  collected  in the same
period in 1994.  As  previously  discussed,  in  accordance  with SFAS 114,  all
payments  received on the Idlewood  Nursing Home mortgage loan  investment  have
been recorded as a reduction of principal in 1995.

The  Partnership  distributed  $250,001  to the  limited  partners  in the first
quarter of 1995 from cash from  operations.  No  distributions  were made in the
first six months of 1994.

Short-term liquidity:
--------------------

At June 30, 1995, the Partnership  held cash and cash equivalents of $3,739,083.
This balance provides a reasonable level of working capital for the Partnerships
immediate needs in operating its properties.

In 1995,  operations of Sterling  Springs  Apartments  and 1130  Sacramento  are
expected  to  provide  sufficient  positive  cash  flow for  normal  operations.
Management  will perform  routine  repairs and  maintenance on the properties to
preserve  and  enhance  their  value  and  competitiveness  in the  market.  The
Partnership has budgeted to spend approximately  $86,000 on capital improvements
to its  properties in 1995,  which are expected to be funded from  operations of
the properties.

For 1995,  management  expects that cash from  operations of its  properties and
principal and interest collections on the mortgage loan investments,  along with
the  present  balance  of  cash  and  cash  equivalents  held,  will  allow  the
Partnership to meet its obligations as they come due.

Long-term liquidity:
-------------------

Only one property,  Sterling  Springs  Apartments,  is encumbered  with mortgage
debt. The mortgage on this property is not due until 2003.

In the event that the Partnership acquires ownership of other properties through
foreclosure, the cash and cash equivalent balances presently held will provide a
source for the maintenance and improvement of the properties. Because the timing
and number of  properties  which may be  foreclosed  is  uncertain,  there is no
assurance that the balances presently held will be sufficient for needed capital
improvements.  At  present,  there are no  commitments  nor any known  needs for
improvements to the properties securing the Partnership's loans. The Partnership
has no existing lines of credit from outside sources.

The General  Partner has  established a revolving  credit facility not to exceed
$5,000,000 in the aggregate  which is available on a "first-come,  first-served"
basis  to  the  Partnership  and  other  affiliated  partnerships,   if  certain
conditions are met.  Borrowings  under the facility may be used to fund deferred
maintenance,  refinancing  obligations  and working  capital needs.  There is no
assurance that the Partnership will receive any funds under the facility because
no amounts are reserved  for any  particular  partnership.  As of June 30, 1995,
$2,362,004  remained  available  for  borrowing  under  the  facility;  however,
additional  funds could become  available as other  partnerships  repay existing
borrowings.

Another possible source of funds is the sale of the Partnership's  mortgage loan
investments or properties securing the Partnership's  mortgage loans. Such sales
are  possibilities  only,  and  since  the  Partnership  does  not  control  the
properties  securing  its  loans,  sales of those  properties  may occur only if
initiated by the  borrower or in the event of  foreclosure  by the  Partnership.
There is no  assurance  that any sales can be  contracted  or closed to coincide
with the  Partnership's  future cash needs.  For the long term, the  Partnership
will  remain  dependent  on  operations  of the  properties  it  owns  or of the
properties securing its loans as the primary source of debt repayment, until the
properties can be sold.
