Many experts agree that the self-storage market has reached the high-water mark, but for the first time in my 20+ year real estate career, the industry is seeing both operational head winds and investment expansion.  Over the last three weeks I have attended several market updates and self-storage investment meetings.  While it is unclear how the self-storage sector will perform in 2018, the majority of the large operators and self-storage REITS are predicting slow to moderate revenue growth in the 3-5% range.  However, the biggest self-storage REIT, Public Storage, is not so bullish on 2018 performance.
