How many houses does united states postal service own?

While the Postal Service holds much property, including Postal stations/branches and processing facilities, as well as extensive land holdings for future growth (in a Land Bank), the Post Office does not own residential houses. The United States Postal Service (USPS) is an "independent agency" of the United States government, established from its predecessor the U.S. Post Office Department, in 1971 as an independent establishment of the executive branch responsible for providing postal services within the United States, according to John Zodrow, who authored the textbook Postal Service Labor Arbitrations. "The USPS is funded through the sales of products and services, and receives no direct taxpayer funds. It is not a corporation, per se. It is still an agency of the federal government."
