Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	10. Commitments and Contingencies Construction Contracts. As of September 30, 2013, we estimate the additional costs to complete 10 consolidated projects currently under construction to be approximately $412.2 million. We expect to fund these amounts through a combination of cash flows generated from operations, draws on our unsecured credit facility or other short-term borrowings, proceeds from property dispositions, equity issued from our ATM program, the use of debt and equity offerings under our automatic shelf registration statement, and secured mortgages. Litigation. One of our wholly-owned subsidiaries previously acted as a general contractor for the construction of two apartment projects in Florida which were subsequently sold and converted to condominium units by unrelated third-parties. One condominium association instituted a lawsuit against our subsidiary alleging a failure to comply with building codes. In June 2013, we entered into a settlement agreement with this association, which resolved this matter in full. Pursuant to this settlement agreement, we made a one-time payment to the association in an amount which was not material. The other association instituted a lawsuit against our subsidiary and other unrelated third-parties alleging negligent construction and failure to comply with building codes. This association is claiming damages for the costs of repair arising out of the alleged defective construction as well as the recovery of incidental and consequential damages resulting from such alleged negligence. We have denied liability to the association. Based upon the amount of discovery completed to date, it is not possible to determine the potential outcome or to estimate a range of loss, if any, which would be associated with any potential adverse decision. We are also subject to various legal proceedings and claims which arise in the ordinary course of business. Matters which arise out of allegations of bodily injury, property damage, and employment practices are generally covered by insurance. While the resolution of these legal proceedings and claims cannot be predicted with certainty, management believes the final outcome of such matters will not have a material adverse effect on our condensed consolidated financial statements. Other Contingencies. In the ordinary course of our business, we issue letters of intent indicating a willingness to negotiate for acquisitions, dispositions, or joint ventures and also enter into arrangements contemplating various transactions. Such letters of intent and other arrangements are non-binding as to either party unless and until a definitive contract is entered into by the parties. Even if definitive contracts relating to the purchase or sale of real property are entered into, these contracts generally provide the purchaser with time to evaluate the property and conduct due diligence, during which periods the purchaser will have the ability to terminate the contracts without penalty or forfeiture of any deposit or earnest money. There can be no assurance definitive contracts will be entered into with respect to any matter covered by letters of intent or we will consummate any transaction contemplated by any definitive contract. Furthermore, due diligence periods for real property are frequently extended as needed. An acquisition or sale of real property becomes probable at the time the due diligence period expires and the definitive contract has not been terminated. We are then at risk under a real property acquisition contract, but generally only to the extent of any earnest money deposits associated with the contract, and are obligated to sell under a real property sales contract. At September 30, 2013, we had made earnest money deposits of approximately $2.3 million for potential acquisitions of operating properties and land, of which approximately $1.3 million is non-refundable. Lease Commitments. At September 30, 2013, we had long-term leases covering certain land, office facilities, and equipment. Rental expense totaled approximately $0.7 million for each of the three months ended September 30, 2013 and 2012, respectively, and approximately $2.1 million and $1.9 million for the nine months ended September 30, 2013 and 2012, respectively. Minimum annual rental commitments for the remainder of 2013 are $0.7 million, and for the years ending December 31, 2014 through 2017 are approximately $3.1 million, $1.9 million, $2.2 million, and $2.2 million, respectively, and approximately $16.4 million in the aggregate thereafter. Investments in Joint Ventures. We have entered into, and may continue in the future to enter into, joint ventures or partnerships (including limited liability companies) through which we own an indirect economic interest in less than 100% of the community or land owned directly by the joint venture or partnership. Our decision whether to hold the entire interest in an apartment community or land ourselves, or to have an indirect interest in the community or land through a joint venture or partnership, is based on a variety of factors and considerations, including: (i) our projection, in some circumstances, that we will achieve higher returns on our invested capital or reduce our risk if a joint venture or partnership vehicle is used; (ii) our desire to diversify our portfolio of investments by market; (iii) our desire at times to preserve our capital resources to maintain liquidity or balance sheet strength; and (iv) the economic and tax terms required by a seller of land or of a community, who may prefer or who may require less payment if the land or community is contributed to a joint venture or partnership. Investments in joint ventures or partnerships are not limited to a specified percentage of our assets. Each joint venture or partnership agreement is individually negotiated, and our ability to operate and/or dispose of land or of a community in our sole discretion is limited to varying degrees in our existing joint venture agreements and may be limited to varying degrees depending on the terms of future joint venture agreements.
