&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;We have various operating leases for office space and equipment. We moved into our current headquarters in Seattle, Washington in August 2011 under an operating lease for which we will be obligated to make escalating monthly lease payments beginning in December 2012 and continuing through November 2022. We lease additional office space in San Francisco, California, Irvine, California, Chicago, Illinois and New York, New York. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The operating lease for our headquarters prior to August 2011 expires in February 2013. As a result of vacating the office space, during the year ended December 31, 2011 we recorded a facility exit charge for $1.7 million related to costs that will continue to be incurred under the operating lease for the remaining term. As of March 31, 2012, there was $1.3 million of accrued facility exit costs included in accrued expenses and other current liabilities. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In March 2011, we entered into a loan and security agreement with a financial institution to establish a line of credit of $4.0 million, secured by substantially all our assets other than our intellectual property, to be used for general business purposes. The line of credit contains financial and non-financial covenants. As of March 31, 2012, we were in compliance with all covenants. The line of credit is available through March 2013. In March 2011, we executed a standby letter of credit of $1.5 million in connection with the lease of our new Seattle offices and reserved this amount against the line of credit, which reduces the available line to $2.5 million. As of March 31, 2012 there were no other amounts outstanding under the line of credit. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;We have four outstanding letters of credit totaling $0.6 million as of March 31, 2012, payable to the landlord of our prior headquarters office in Seattle, Washington, in the event we default on our lease, which expires in February 2013. The letters of credit are secured by our investments and are effective until 60 days after the expiration date of the lease. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Legal Proceedings &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;There have been no material developments in legal proceedings during the quarter ended March 31, 2012. For a description of previously reported legal proceedings, refer to Part I, Item 3 (Legal Proceedings) of our Annual Report on Form 10-K for the year ended December 31, 2011. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;From time to time, we are involved in litigation and claims that arise in the ordinary course of business. Although we cannot be certain of the outcome of any litigation and claims, nor the amount of damages and exposure that we could incur, we currently believe that the final disposition of such matters will not have a material effect on our financial position, results of operations or cash flow. This forward-looking statement is based on management's current understanding of the relevant law and facts, and it is subject to various contingencies, including the potential costs and risks associated with litigation and the actions of arbitrators, judges and juries. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. &lt;/font&gt;&lt;/p&gt; &lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Upon execution of the underwriting agreement related to our initial public offering of our Class A common stock ("IPO") on July 19, 2011, our 2011 Incentive Plan (the "2011 Plan") became effective. The 2011 Plan is administered by the compensation committee of the board of directors. Under the terms of the 2011 Plan, the compensation committee of the board of directors may grant equity awards, including incentive stock options or nonqualified stock options, to employees, officers, directors, consultants, agents, advisors and independent contractors. After the effective date of the 2011 Plan, all equity awards have been, and will be, granted under the 2011 Plan rather than the Amended and Restated 2005 Equity Incentive Plan (the "2005 Plan"), which was the preexisting plan. On August 5, 2011, we filed a registration statement on Form S-8 under the Securities Act of 1933, as amended (the "Securities Act"), to register 6,816,135 shares of our Class A common stock for issuance under our 2005 Plan and 2011 Plan. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Stock Options &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;All stock options outstanding under the 2005 Plan and the 2011 Plan are nonqualified stock options. Options under the 2011 Plan are granted with an exercise price per share not less than 100% of the fair market value of our Class A common stock on the date of grant, and are exercisable at such times and under such conditions as determined by the compensation committee. Under the 2011 Plan, the maximum term of an option is ten years from the date of grant. Any portion of an option that is not vested and exercisable on the date of a participant's termination of service expires on such date. Employees generally forfeit their rights to exercise vested options after 3 months or 12 months following their termination of employment, depending on the reason for the termination. Options granted to date under the 2011 Plan have been granted with seven-year terms. Options granted under the 2011 Plan typically vest 25% after 12 months and ratably thereafter over the next 36 months, except for options granted under the Stock Option Grant Program for Nonemployee Directors ("Nonemployee Director Awards"), which are fully vested and exercisable on the grant date. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;During the three months ended March 31, 2012, stock options for 45,005 shares of our Class A common stock were granted as Nonemployee Director Awards. The fair value of options granted for the Nonemployee Director Awards, $11.52 per share, is estimated at the date of grant using the Black-Scholes-Merton option-pricing model, assuming no dividends, and expected volatility of 51%, a risk-free interest rate of 0.43%, and a weighted-average expected life of 3.5 years. During the three months ended March 31, 2012, share-based compensation expense recognized in our statement of operations related to Nonemployee Director Awards was $0.5 million, and is included in general and administrative expenses. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Restricted Stock &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In consideration for the acquisition of substantially all of the operating assets of Diverse Solutions, Inc. ("Diverse Solutions") under the terms of the asset purchase agreement, Zillow issued to Diverse Solutions 75,000 restricted shares of Zillow's Class A common stock effective on October 31, 2011. The grant date fair value of the restricted shares is approximately $2.2 million. One-third of the restricted shares will vest and no longer be subject to forfeiture on the first anniversary of the vesting commencement date, which is October 31, 2012, subject to Justin LaJoie's (the controlling shareholder of Diverse Solutions) continued employment or service to Zillow until such date. The remaining shares will vest ratably over the twenty-four months following such first anniversary, subject to Mr. LaJoie's continued employment or service to Zillow. In the event of Mr. LaJoie's termination of service by Zillow without cause or by Mr. LaJoie for good reason, any unvested shares on the date of such termination will become vested and no longer subject to forfeiture. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The fair value of the restricted shares relates to post-combination services and will be recorded as share-based compensation expense over the vesting period. As of March 31, 2012, there was $1.9 million of total unrecognized compensation cost related to the restricted shares. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Basic net income (loss) per share is computed by dividing net income (loss) attributable to common shareholders by the weighted-average number of common shares (including Class A common stock, Class B common stock and Class C common stock) outstanding during the period. For the three months ended March 31, 2011, no losses were allocated to Series A, B and C convertible preferred shareholders, as these shareholders did not have contractual obligations to share in or fund the losses of the Company. Thus, for the three months ended March 31, 2011, the net loss is allocated entirely to the Class A common stock, Class B common stock and Class C common stock. &lt;/font&gt;&lt;/p&gt;

Potential Class A common stock equivalents consist of Class A common stock issuable upon exercise of stock options using the treasury stock method, and for the three months ended March 31, 2011, include Class A common stock issued upon the automatic conversion of our Series A, B and C convertible preferred stock on July 19, 2011. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;For the three months ended March 31, 2012, 2,579,693 Class A common stock equivalents underlying stock options were included in the computation of diluted net income per share attributable to common shareholders because they had a dilutive impact. For the three months ended March 31, 2012, 66,653 shares of Class A common stock underlying nonvested restricted shares were included in the computation of diluted net income per share attributable to common shareholders as they had a dilutive impact. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;For the three months ended March 31, 2011, 5,477,032 shares underlying stock options and 9,276,190 shares of Class A common stock issued upon the automatic conversion of our convertible preferred stock on July 19, 2011 have been excluded from the calculations of diluted net loss per share attributable to common shareholders because their effect would have been antidilutive. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The standards also establish a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;We applied the following methods and assumptions in estimating our fair value measurements: &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;i&gt;Cash equivalents &lt;/i&gt;&amp;#8212; Cash equivalents are comprised of highly liquid investments, including money market funds and certificates of deposit with original maturities of less than three months. The fair value measurement of these assets is based on quoted market prices in active markets and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 1 in the fair value hierarchy. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;i&gt;Short-term and long-term investments&lt;/i&gt; &amp;#8212; Our investments consist of fixed income U.S. government agency securities. The fair value measurement of these assets is based on observable market-based inputs or inputs that are derived principally from or corroborated by observable market data by correlation or other means, and therefore is classified as Level 1 in the fair value hierarchy. Our government agency securities are classified as held-to-maturity and are recorded at amortized cost, as we do not intend to sell the investments, and it is not more likely than not that we will be required to sell these investments prior to maturity. The amortized cost of our government agency securities approximates their fair value. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;We have one reportable segment. Our reportable segment has been identified based on how our chief operating decision-maker manages our business, makes operating decisions and evaluates operating performance. The chief executive officer acts as the chief operating decision-maker and reviews financial and operational information on an entity-wide basis. We have one business activity and there are no segment managers who are held accountable for operations, operating results or plans for levels or components. Accordingly, we have determined that we have a single reporting segment and operating unit structure. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The accompanying condensed financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP") and applicable rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed financial statements should be read in conjunction with the audited financial statements and accompanying notes as of and for the year ended December 31, 2011 included in the Company's Annual Report on Form 10-K, which was filed with the SEC on March 2, 2012. The condensed balance sheet as of December 31, 2011, included herein, was derived from the audited financial statements as of that date. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The unaudited condensed interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly our financial position as of March 31, 2012, our results of operations for the three months ended March 31, 2012 and 2011, and our cash flows for the three months ended March 31, 2012 and 2011. The results of the three month period ended March 31, 2012 are not necessarily indicative of the results to be expected for the year ended December 31, 2012 or for any other interim period or for any other future year. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The preparation of financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Estimates are used for revenue recognition, the allowance for doubtful accounts, website development costs, goodwill, recoverability of intangible assets with definite lives and other long-lived assets and for share-based compensation. To the extent there are material differences between these estimates, judgments, or assumptions and actual results, our financial statements will be affected. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In May 2011, the FASB amended existing rules covering fair value measurement and disclosure to clarify guidance and minimize differences between GAAP and International Financial Reporting Standards ("IFRS"). The guidance requires entities to provide information about valuation techniques and unobservable inputs used in Level 3 fair value measurements and provide a narrative description of the sensitivity of Level 3 measurements to changes in unobservable inputs. The guidance is effective during interim and annual periods beginning after December 15, 2011. We adopted this guidance on January 1, 2012. The adoption of this guidance did not have any impact on our financial position, results of operations or cash flows. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In June 2011, the FASB issued guidance on the presentation of comprehensive income to increase the prominence of other comprehensive income in the financial statements. An entity has the option to present the components of net income and comprehensive income in either one or two consecutive financial statements. This guidance is effective for interim and annual reporting periods beginning after December 15, 2011, with earlier adoption permitted, and must be applied retrospectively. We adopted this guidance on January 1, 2012. The adoption of this guidance did not have any impact on our financial position, results of operations or cash flows as we do not have any items of other comprehensive income in any period presented and therefore we are not required to report other comprehensive income or comprehensive income. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In September 2011, the FASB issued guidance on testing goodwill for impairment to permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This guidance is effective for fiscal years beginning after December 15, 2011, with earlier application permitted. We early adopted this guidance for our annual goodwill impairment test performed in our fourth quarter of 2011. The early adoption of this guidance did not have any impact on our financial position, results of operations or cash flows. &lt;/font&gt;&lt;/p&gt; &lt;/div&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

&lt;p style="margin-top: 12px; text-indent: 64px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In April 2012, we amended our loan and security agreement with a financial institution to increase our line of credit from $4.0 million to $25.0 million. The line of credit is secured by substantially all our assets, including our intellectual property. The revolving line of credit contains customary financial covenants, including the maintenance of a minimum adjusted quick ratio, measured on a monthly basis, of 1.50 to 1.00, and minimum Adjusted EBITDA, measured on a quarterly basis, of greater than or equal to negative $5.0 million for each quarterly period through December 31, 2012 and greater than or equal to $0 for each quarterly period thereafter. In addition, the revolving line of credit contains restrictions on our ability to, among other things, engage in certain mergers and acquisition transactions and create liens on assets. The line of credit is available through April 2016. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 64px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In May 2012, Zillow, RentJuice Corporation, a Delaware corporation ("RentJuice"), Renegade Acquisition, Inc., a Delaware corporation and wholly owned subsidiary of Zillow ("Merger Sub"), and Shareholder Representative Services LLC, acting as the stockholder representative, entered into an Agreement and Plan of Merger (the "Merger Agreement") providing for the acquisition of RentJuice by Zillow. Under the terms and subject to the conditions of the Merger Agreement, Merger Sub will merge with and into RentJuice, with RentJuice remaining as the surviving company and a wholly owned subsidiary of Zillow (the "Merger"). The total Merger consideration payable to RentJuice equity holders is approximately $40 million in cash, less certain transaction expenses and other costs. All vested options to purchase shares of RentJuice's common stock will be cancelled and, in settlement of such cancellation, the holders of such options will receive cash payments representing a portion of the Merger consideration. A portion of the Merger consideration will be attributed to the substitution of unvested stock options of RentJuice outstanding as of the closing for stock options to purchase shares of our Class A common stock at an exchange ratio implied by the Merger consideration. The Merger is expected to close in the second quarter of 2012. Pursuant to the terms of the Merger Agreement, we have agreed to adopt a retention bonus plan after the closing pursuant to which restricted stock units for 280,978 shares of our Class A common stock will be granted to employees of RentJuice who accept employment with Zillow in proportion to each employee's total equity holdings in RentJuice prior to the closing of the Merger. Twenty-five percent of each restricted stock unit award will vest on the one-year anniversary of the closing of the Merger and the remainder will vest in substantially equal installments each three-month period thereafter for the next three years, subject to the recipient's continued full-time employment or service to Zillow. &lt;/font&gt;&lt;/p&gt; &lt;/div&gt;</us-gaap:SubsequentEventsTextBlock>
