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.
