Exhibit (a)(9)

May 18, 2007

TO:      UNIT HOLDERS OF CONSOLIDATED CAPITAL INSTITUTIONAL PROPERTIES 2

SUBJECT: EXTENDED AND FURTHER INCREASED OFFER TO PURCHASE UNITS

Dear Unit Holder:

We are amending the Offer to Purchase and related Letters of Transmittal sent to
you on March 26, 2007, as amended May 4, 2007 (the  "Offer"),  which was made by
the Purchasers  identified in the Offer. The Purchasers are offering to purchase
up  to  181,811  Units  of  limited   partnership   interest  (the  "Units")  in
CONSOLIDATED  CAPITAL  INSTITUTIONAL  PROPERTIES  2 (the  "Partnership")  at the
further increased Offer Price of:

                                  $12 per Unit

The Offer will provide you with an  opportunity  to liquidate  all, or a portion
of, your investment  without the usual  transaction costs associated with market
sales or  partnership  transfer  fees.  Reasons  you may wish to sell your Units
include:

o     HIGHEST  OFFER PRICE YET.  This offer is 20% HIGHER than what an affiliate
      of the General Partner is currently  offering,  as amended.  Withdraw your
      Units from AIMCO and tender them to us for $2 per Unit more!

o     NO  DISTRIBUTIONS!  The Partnership has paid no distributions  since 2001!
      The  Partnership  has  stated  that  "there can be no  assurance  that the
      Partnership will generate sufficient funds from operations,  after planned
      capital expenditures,  to permit any distributions to its partners in 2007
      or subsequent periods." (emphasis added)

o     UNCERTAINTY  OF PARTNERSHIP  TERMINATION.  Our offer provides you with the
      opportunity  to  receive  liquidity.  The  general  partner  has  given no
      indication when the partnership will be liquidating.  The Partnership term
      extends through 2013! Therefore,  investors may not see liquidity for some
      time.

o     NO FUTURE  IRS  FILING  REQUIREMENTS.  The tax year in which you sell your
      Units will be the final year for which you will be obligated to file a K-1
      for the Partnership  with your tax return.  This may represent a reduction
      in costs associated with filing complicated tax returns.  Your decision to
      sell  may  have  other  favorable  or  unfavorable  tax  consequences  and
      potential sellers should consult their individual tax advisers.

The Purchasers  are extending the Expiration  Date to June 5, 2007. You can view
the amended  Offer  materials at  www.mpfi.com  (Click on MPF  Tenders).  If you
already  completed and sent a Letter of Transmittal to the Depositary,  you need
not send another, you will automatically receive the higher price. You no longer
have to get a Medallion Guarantee.

After  carefully  reading the enclosed Offer, if you elect to tender your Units,
mail (using the  enclosed  pre-addressed,  postage  paid  envelope) or fax (then
mail) a duly completed and executed copy of the Letter of  Transmittal  (printed
on pink paper) and change of address forms, and any other documents  required by
the Letter of Transmittal, to the Depositary for the Offer at:

                         MacKenzie Patterson Fuller, LP
                               1640 School Street
               Moraga, California 94556 Facsimile: (925) 631-9119

We've  enclosed a Notice of Withdrawal  that you can fax or deliver to the agent
for AIMCO  Properties,  LP if you already  tendered  your Units to AIMCO and you
wish to receive  more  money!  The AIMCO Offer  expires on May 30, 2007  (unless
further extended), so its depository, The Altman Group, must receive your Notice
of  Withdrawal  by midnight  Eastern Time on that date for you to withdraw  from
that  offer.  You must also  deliver  to us an  executed  copy of our  Letter of
Transmittal to accept our Offer.  If you have any questions or need  assistance,
please call the Depositary at 800-854-8357.
