TO PROSPECTUS DATED SEPTEMBER 21, 2009

APPLE REIT NINE, INC.

The following information supplements the prospectus of Apple REIT Nine, Inc. dated September 21, 2009 and is part of the prospectus. This Supplement updates the information presented in the prospectus. Prospective investors should carefully review the prospectus, Supplement No. 11 (which is cumulative and replaces all prior Supplements), Supplement No. 12 and this Supplement No. 13.

TABLE OF CONTENTS

Certain forward-looking statements are included in the prospectus and this supplement. These forward-looking statements may involve our plans and objectives for future operations, including future growth and availability of funds. These forward-looking statements are based on current expectations, which are subject to numerous risks and uncertainties. Assumptions relating to these statements involve judgments with respect to, among other things, the continuation of our offering of Units, future economic, competitive and market conditions and future business decisions, together with local, national and international events (including, without limitation, acts of terrorism or war, and their direct and indirect effects on travel and the economy). All of these matters are difficult or impossible to predict accurately and many of them are beyond our control. Although we believe the assumptions relating to the forward-looking statements, and the statements themselves, are reasonable, any of the assumptions could be inaccurate and, therefore, there can be no assurance that these forward-looking statements will prove to be accurate. In light of the significant uncertainties inherent in these forward-looking statements, the inclusion of this information should not be regarded as a representation by us or any other person that our objectives and plans, which we consider to be reasonable, will be achieved.

We completed the minimum offering of Units (with each Unit consisting of one Common Share and one Series A Preferred Share) at $10.50 per Unit on May 14, 2008.

RECENT DEVELOPMENTS

Recent Purchases

On August 31, 2010, through one of our indirect wholly-owned subsidiaries, we closed on the purchase of three hotels located in Rogers, Arkansas, St. Louis, Missouri, and Kansas City, Missouri. On September 15, 2010, through one of our indirect wholly-owned subsidiaries, we closed on the purchase of a hotel located in Alexandria, Louisiana. The aggregate gross purchase price for these hotels, which contain a total of 530 guest rooms, was approximately $52.6 million.

Further information about our recently purchased hotels is provided in other sections below.

Loan Assumptions

The purchase contracts for three of the recently purchased hotels required us to assume loans secured by these hotels. The total outstanding aggregate principal balance of the assumed loans is $28.8 million. Each of the assumed loans has a non-recourse structure, which means that the lender generally must rely on the property, rather than the borrower, as the lender’s source of repayment in any collection action. There are exceptions to the non-recourse structure in certain situations, such as misappropriation of funds and environmental liabilities. In these situations, the lender would be permitted to seek repayment from the guarantor or indemnitor of the loan, which is one of our indirect wholly-owned subsidiaries.

Recent Purchase Contracts

We caused one of our indirect wholly-owned subsidiaries to enter into a series of purchase contracts for the potential purchase of 17 hotels.

The total gross purchase price for these hotels, which contain a total of 2,376 guest rooms, is approximately $297.8 million. Deposits totaling $5.1 million have been made and certain contracts require an additional aggregate deposit in the amount of $8.2 million at or after the end of our contractual review periods. A number of required conditions to closing currently remain unsatisfied under each of the purchase contracts. Accordingly, there can be no assurance at this time that any closings will occur under these purchase contracts. Upon a purchase, the deposit amounts would be credited against the applicable purchase price.

Further information about these purchase contracts and hotels is provided in the “Acquisitions and Related Matters” section below.

Source of Funds and Related Party Payments

Our recent purchases, which resulted in our ownership of four additional hotels, were funded primarily by the proceeds from our ongoing offering of Units. Our offering proceeds also have been

S-3

used to fund the initial deposits required by the hotel purchase contracts and will be used for the related additional deposits.

We have entered into a property acquisition and disposition agreement with Apple Suites Realty Group, Inc. to acquire and dispose of our real estate assets. A fee of 2% of the gross purchase price or gross sale price in addition to certain reimbursable expenses will be payable for these services. This entity is owned by Glade M. Knight, who is our Chairman and Chief Executive Officer. We used our offering proceeds to pay $1,052,901 to Apple Suites Realty Group, Inc., representing 2% of the gross purchase price for our recent purchases.

Overview of Owned Hotels

As a result of our recent purchases, we currently own 52 hotels, which are located in the states indicated in the map below:

SUMMARY OF CONTRACTS
FOR OUR RECENTLY PURCHASED PROPERTIES

Hotel Lease Agreements

Each of our recently purchased hotels is covered by a separate hotel lease agreement between the owner (one of our indirect wholly-owned subsidiaries) and the applicable lessee (another one of our indirect wholly-owned subsidiaries, as specified in the previous section). Each lease provides for an initial term of 10 years. The applicable lessee has the option to extend its lease term for two additional five-year periods, provided it is not in default at the end of the prior term or at the time the option is exercised.

Each lease provides for annual base rent and percentage rent. The annual base rent is payable in advance in equal monthly installments and will be adjusted each year in proportion to the Consumer Price Index (based on the U.S. City Average). Shown below are the annual base rent and the lease commencement date for our recently purchased hotels:

The annual percentage rent depends on a formula that compares fixed “suite revenue breakpoints” with a portion of “suite revenue,” which is equal to gross revenue from guest rentals less sales and room taxes and credit card fees. The suite revenue breakpoints will be adjusted each year in proportion to the Consumer Price Index (based on the U.S. City Average). Specifically, the annual percentage rent is equal to the sum of (a) 17% of all suite revenue for the year, up to the applicable suite revenue breakpoint; plus (b) 55% of the suite revenue for the year in excess of the applicable suite revenue breakpoint, as reduced by base rent paid for the year.

Management Agreements

Each of our hotels is being managed by the manager under a separate management agreement between the manager and the applicable lessee (which is one of our indirect wholly-owned subsidiaries, as specified in the previous section). The manager is responsible for managing and supervising the daily operations of the hotel and for collecting revenues for the benefit of the applicable lessee. The fees and other terms of these agreements are the result of commercial negotiations between otherwise unrelated parties. We believe that such fees and terms are appropriate for the hotels and the markets in which they operate.

Franchise Agreements

For the hotel franchised by Marriott International, Inc. or one of its affiliates, there is a relicensing franchise agreement between the lessee and Marriott International, Inc. or an affiliate. Each relicensing franchise agreement provides for the payment of royalty fees and marketing contributions to the franchisor. A percentage of gross room revenues is used to determine these payments. In addition, we have caused Apple Nine Hospitality, Inc. or another one of our subsidiaries to provide a separate guaranty of the payment and performance of the applicable lessee under the relicensing franchise agreement.

For the hotels franchised by Hilton Worldwide or one of its affiliates, there is a franchise license agreement between the applicable lessee and Hilton Worldwide or an affiliate. Each franchise license agreement provides for the payment of royalty fees and program fees to the franchisor. A percentage of gross room revenues is used to determine these payments. Apple Nine Hospitality, Inc. or another one of our subsidiaries has guaranteed the payment and performance of the lessee under the applicable franchise license agreement.

The fees and other terms of these agreements are the result of commercial negotiations between otherwise unrelated parties, and we believe that such fees and terms are appropriate for the hotels

S-7

and the markets in which they operate. These agreements may be terminated for various reasons, including failure by the applicable lessee to operate in accordance with the standards, procedures and requirements established by the franchisors.

FINANCIAL AND OPERATING INFORMATION
FOR OUR RECENTLY PURCHASED
PROPERTIES

Our hotels offer guest rooms and suites, together with related amenities, that are consistent with their operations. The hotels are located in developed or developing areas and in competitive markets. We believe the hotels are well-positioned to compete in their markets based on location, amenities, rate structure and franchise affiliation. In the opinion of management, each hotel is adequately covered by insurance. The following tables present further information about our hotels:
