PROPERTY UPDATE

The twelve properties owned by Rancon Realty Fund IV as a part of the Tri City Corporate Centre include the following five office buildings and seven retail properties.

As of September 30, 2013, the weighted average occupancy of the twelve properties was 76%, up from 71% at September 30, 2012. Rental revenue and other increased by $71,000, or 4%, and $91,000, or 2% for the three and nine months ended September 30, 2013, compared to the three and nine months ended September 30, 2012, respectively. The increase is primarily related to lease cancellation fees from a tenant at One Vanderbilt who is vacating in the fourth quarter of 2013.

Property operating expenses increased $19,000, or 2%, and $91,000, or 3%, for the three and nine months ended September 30, 2013, compared to the three and nine months ended September 30, 2012, respectively. These increases are primarily the result of increased earthquake insurance premiums and utility expenses, net of a reduction in utility costs due to less usage of after hours HVAC by tenants.

VALUATION ESTIMATE FOR 2014

The per Unit valuation estimate for Rancon Realty Fund IV as of December 31, 2013, is $607 per Unit. The General Partners have established the per Unit valuation estimate based solely on the estimated net asset value of the Partnership’s properties and other assets. For further detail on how the valuation was determined, please refer to our Current Report on Form 8-K, dated December 19, 2013, which has been filed with the SEC, and can be obtained by request to Investor Services or from the SEC’s website at www.sec.gov.

Unlike stocks and mutual funds, which experience daily price changes, the Partnership’s valuation of its outstanding Units is made once a year, as of December 31, and is not revised throughout the year. It thus does not reflect changes in the net asset value of the Partnership’s properties and other assets that may occur throughout the year. No third-party appraisals were obtained in connection with the General Partners’ valuation of the Units, and the General Partners’ valuation and the methodology they employed to value the Units has not been verified or reviewed by any third-party advisor, including Rancon IV’s auditors. The actual amount for which the Partnership’s properties are eventually sold may be materially lower than the current estimates of their fair market values made by the General Partners. The General Partners’ valuation of the Units also does not represent the price Units can be sold for on the informal secondary market. That price is generally 10 to 40% of the current per Unit valuation, less any fees or commissions that may be charged.

PARTNERSHIP DISSOLUTION APPROACHING

As we have mentioned in previous correspondence, Rancon IV is required, by the terms of its partnership agreement, to dissolve on December 31, 2015. During the course of this year, we have been exploring the options available in connection with the anticipated dissolution of the Partnership. The current plan is to develop and prepare a Consent Solicitation Statement (“Consent Statement”) in compliance with the partnership agreement and the SEC’s proxy rules, and to send the Consent Statement to all Limited Partners in the first half of 2014. Limited Partners do not need to do anything now; the Consent Statement will be mailed to you at your address of record as maintained by the Partnership.

The Consent Statement will request the approval of the Limited Partners to dissolve and to begin an orderly liquidation of the Partnership’s assets, which would include selling all the properties of the Partnership and distributing the net proceeds to the Limited Partners. The Consent Statement would include information about the Partnership and the proposed dissolution in accordance with the SEC’s proxy rules. Dissolution of the Partnership prior to December 31, 2015, will require approval by the Limited Partners holding a majority of the outstanding units of the Partnership.

During the consent solicitation process, we plan to interview one or more real estate brokerage firms for the purpose of identifying those that could create a comprehensive marketing plan to sell the properties owned by Rancon IV. Retention of any firm would be conditional upon approval of the Partnership’s dissolution by the Limited Partners of Rancon IV. The firm or firms selected would then move forward in presenting the properties in their best light to attract the most promising potential buyers. Many factors will influence the timing of the sale of the properties, including the local markets in which the properties of the Partnership are located and the state of the local and national economies.

This letter also includes unaudited financial information for the quarter ended September 30, 2013. Reference is made to the Partnership’s Quarterly Report on Form 10-Q, as filed with the SEC, for further information on the Partnership’s result of operations for the quarter ended September 30, 2013.
