Exhibit 99.1

January 28, 2013

Dear Limited Partner in Rancon Realty Fund IV:

During the time that Rancon IV has existed, the investment culture has gone full-circle several times. Real estate investments, stocks and mutual funds, municipal bonds, even gold and precious metals have been in and out of favor. Revisions to state and federal income tax regulations have had an impact on the perceived and actual value of investments. Today, the media is filled with concerns about unemployment, gas prices and even the fiscal cliff. Throughout it all, the long-term goal of your partnership has remained the same – to create, improve and maintain the value of the properties owned by Rancon IV.

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.

Combined occupancy at the properties increased from 69% as of September 30, 2011, to 71% as of September 30, 2012. According to the recent CBRE MarketView report on the Inland Empire Office Market, “Since the fourth quarter of 2008, the overall vacancy rate in the Inland Empire has been above 20% and is expected to remain at this level…through the third quarter of next year.” Occupancy at the Rancon IV Office Properties is at the 79% level, reflective of CBRE’s observations. The corresponding CBRE MarketView report on the Inland Empire Retail Market

indicates that “The Inland Empire retail market was among those hardest hit…[however] rental rates should begin to slowly tick upwards into the second half of next year.” Our goal is to strengthen property values by increasing occupancy, and by managing the upkeep and appearance of the properties and grounds.

Rancon IV is required, by the terms of its partnership agreement, to dissolve by no later than December 31, 2015. In 2013, we intend to explore the options available in connection with the anticipated dissolution of the Partnership.

VALUATION ESTIMATE FOR 2013

The per Unit valuation estimate for Rancon Realty Fund IV as of December 31, 2012, is $610 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 January 25, 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.

Some investors have contacted us, asking how to liquidate (sell) their Partnership Units. Remember that Rancon Realty Fund IV is not publicly traded, so options for selling are extremely limited. Upon request, we can provide a list of potential buyers that you can contact and possibly negotiate with to facilitate the sale of your Units. While we can provide a list of potential buyers, we cannot confirm the potential buyers’ ability to follow through on any proposal they may make to you to purchase your Units. Anyone who purchases Rancon IV units does so at prices between 10% and 40% of the current valuation estimate (noted above).

This letter also includes unaudited financial information for the quarter ended September 30, 2012. 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, 2012.
