Nov 1 (Reuters) - Public Storage said on Monday it bought 56 self-storage properties mainly in the Dallas-Fort Worth region from All Storage for $1.5 billion.

The purchase, funded by unsecured debt, would immediately add to Public Storage's funds from operations - a measure of cash flow.

Self-storage companies rent storage space to people. (Reporting by Sanjana Shivdas in Bengaluru; Editing by Aditya Soni)
