Accounting Policies, by Policy (Policies)	3 Months Ended
Apr. 30, 2013
Use of Estimates, Policy [Policy Text Block]	USE OF ESTIMATES The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Trust’s operations are affected by numerous factors, including the economy, competition in the hotel industry and the effect of the economy on the travel and hospitality industries. The Trust cannot predict if any of the above items will have a significant impact in the future, nor can it predict what impact, if any, the occurrence of these or other events might have on the Trust’s operations and cash flows. Significant estimates and assumptions made by management include, but are not limited to, the estimated useful lives of long-lived assets and estimates of future cash flows used to test a long-lived asset for recoverability and the fair values of the long-lived assets.
Assets Held for Sale [Policy Text Block]	ASSETS HELD FOR SALE OR USE The Trust considers assets held for sale when management approves and commits to a formal plan to actively market a property or group of properties for sale and a signed sales contract and significant non-refundable deposit or contract break-up fee exists. Upon designation as an asset held for sale, we record the carrying value of each property or group of properties at the lower of its carrying value or its estimated fair value, less estimated costs to sell, and we cease the recognition of depreciation expense. Any gain realized in connection with the sale of a property for which we have significant continued involvement (such as through a long-term management agreement) is deferred and recognized over the initial term of the related agreement. The operations of the properties held for sale prior to the sale date are recorded in discontinued operations unless we will have continuing involvement (such as through a management agreement) after the sale. No assets were deemed held for sale as of April 30, 2013 or January 31, 2013.
Liquidity Disclosure [Policy Text Block]	LIQUIDITY Our principal source of cash to meet our cash requirements, including distributions to our shareholders, is our share of the Partnership’s cash flow, quarterly distributions from Albuquerque, New Mexico property, and through the Partnership and our direct ownership of the Yuma, Arizona property. The Partnership’s principal source of revenue is hotel operations for the one hotel property it owns and quarterly distributions from the Tucson, Arizona and Ontario, California properties. Our liquidity, including our ability to make distributions to our shareholders, will depend upon our ability and the Partnership’s ability to generate sufficient cash flow from hotel operations and to service our debt. Hotel operations are significantly affected by occupancy and room rates. Occupancy increased from the first three months of fiscal year 2013 to the first three months of fiscal year 2014, while rates decreased. Results are also significantly impacted by overall economic conditions and specifically conditions in the travel industry. Unfavorable changes in these factors could negatively impact hotel room demand and pricing, which would reduce the Trust’s profit margins on rented suites. During fiscal year 2014, capital improvements are expected to be reduced by approximately $800,000 from the prior year and we expect increased cash flow from the reduction of principal and interest payments on the Ontario property. Additionally, we have a $600,000 bank line of credit which matures on June 23, 2013. On June 11, 2013, IHT renewed this line of credit to June 23, 2014 with all other terms and conditions remaining the same. As of April 30, 2013, the Trust had $178,201 drawn on this line of credit. With the expected decrease in capital improvements, the availability of the $600,000 bank line of credit and increased cash flow from the reduction of principal and interest payments on the Ontario property, management believes that it will have enough cash on hand to meet all of our financial obligations as they become due for at least the next year. In addition, our management is analyzing other strategic options available to us, including the refinancing of another property or raising additional funds through additional non-controlling interest sales; however, such transactions may not be available or available at terms that are favorable to the Trust. We anticipate a moderate improvement in the weak overall economic situation that negatively affected results in fiscal year 2012 and 2013, which could result in higher revenues and operating margins. Challenges in fiscal year 2014 are expected to include continued competition for all types of business in the markets in which we operate and our ability to maintain room rates while maintaining market share.
Revenue Recognition, Policy [Policy Text Block]	REVENUE RECOGNITION Room, food and beverage, management and licensing fees, and other revenue are recognized as earned as services are provided and items are sold. Sales taxes collected are excluded from gross revenue.
Earnings Per Share, Policy [Policy Text Block]	INCOME PER SHARE Basic and diluted income per Share of Beneficial Interest is computed based on the weighted-average number of Shares of Beneficial Interest and potentially dilutive securities outstanding during the period. Dilutive securities are limited to the Class A and Class B units of the Partnership, which are convertible into 3,693,972 shares of the Beneficial Interest, as discussed in Note 1. For the three-month periods ended April 30, 2013 and 2012, there were Class A and Class B Partnership units outstanding, which are convertible into Shares of Beneficial Interest of the Trust. At the beginning of each period, the aggregate weighted-average of these Shares of Beneficial Interest would have been 3,693,972 and 3,695,804 when converted in addition to the basic shares outstanding for the quarters ended April 30, 2013 and 2012, respectively. These Shares of Beneficial Interest issuable upon conversion of the Class A and Class B Partnership units were dilutive during both three-month periods ended April 30, 2013 and 2012.

Disclosure of accounting policy for computing basic and diluted earnings or loss per share for each class of common stock and participating security. Addresses all significant policy factors, including any antidilutive items that have been excluded from the computation and takes into account stock dividends, splits and reverse splits that occur after the balance sheet date of the latest reporting period but before the issuance of the financial statements.

Disclosure of accounting policy for reporting when there is a substantial doubt about an entity's ability to continue as a going concern for a reasonable period of time (generally a year from the balance sheet date). Disclose: (a) pertinent conditions and events giving rise to the assessment of substantial doubt about the entity's ability to continue as a going concern for a reasonable period of time, (b) the possible effects of such conditions and events, (c) management's evaluation of the significance of those conditions and events and any mitigating factors, (d) possible discontinuance of operations, (e) management's plans (including relevant prospective financial information), and (f) information about the recoverability or classification of recorded asset amounts or the amounts or classification of liabilities. If management's plans alleviate the substantial doubt about the entity's ability to continue as a going concern, disclosure of the principal conditions and events that initially raised the substantial doubt about the entity's ability to continue as a going concern would be expected to be considered. Disclose whether operations for the current or prior years generated sufficient cash to cover current obligations, whether waivers were obtained from creditors relating to the company's default under the provisions of debt agreements and possible effects of such conditions and events, such as: whether there is a possible need to obtain additional financing (debt or equity) or to liquidate certain holdings to offset future cash flow deficiencies. Disclose appropriate parent company information when parent is dependent upon remittances from subsidiaries to satisfy its obligations.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
