Joseph D. Margolis
Chief Executive Officer at Extra Space Storage
Thanks, Jeff, and thank you, everyone, for joining today's call. We had another strong quarter to cap off an exceptional year. Our 2022 same-store revenue growth of 17.4% is the highest in our company's history. And for the second consecutive year, core FFO growth was above 20%. I am proud of the Extra Space team for another year of strong performance across all aspects of the business. Now speaking to the fourth quarter, despite difficult comps in the return of seasonality, same-store revenue growth was ahead of our expectations at 11.8%.
Vacates continued to normalize during the quarter, and demand remained seasonally steady, leading to strong same-store occupancy levels ending the year at 94.2%. Our high occupancy allowed us to maximize revenue and grow customer rates across the portfolio. Despite offering lower rates to new customers, total net rent per square foot increased 12.8% year-over-year. We experienced expense pressure across many line items with same-store expense growth of 6.7%, resulting in same-store NOI growth of 13.4%.
We were busy on the external growth front, acquiring 10 stores in the REIT or in joint ventures, adding 46 stores gross to our third-party management platform and closing over $250 million in bridge loans. We were also very focused on integrating our 2022 strategic acquisitions, including the Storage Express portfolio, which is already slightly ahead of our underwriting. We anticipate full integration of the properties onto our platform by the end of the second quarter, which will provide additional digital marketing, revenue management and operational efficiencies.
We have also started to test new operational strategies at both Storage Express and Extra Space stores and we are beginning to see some early external growth opportunities in new and existing markets for Storage Express. Our strong property NOI, plus our external growth efforts, resulted in core FFO growth of 9.4% in the quarter and 22.1% for the year. This allowed our Board of Directors to increase our first quarter dividend by 8%, contributing to a total five year increase of 108%. As we look forward to 2023, we are encouraged by the fundamentals of the business.
New supply continues to moderate from 2018, 2019 peaks, and we expect even lower competition from new supply in our markets in 2023. Customer demand has been steady, occupancy has remained high, and same-store revenue growth remained above 10% through December. Our strong occupancy has allowed us to sequentially increase rates month-over-month to new customers since November. And we believe elevated occupancy will give us greater pricing power with new and existing customers as we move through the leasing season.
We expect to face continued expense pressures, but at lower levels than experienced in 2022, resulting in same-store NOI guidance of 3% to 5.5%. While this level of growth represents moderation from 2022 levels, it is in line with historical norms, and we believe it will compare well to other asset classes in the current environment. Our investment strategy is long-term focused. And we have made strategic decisions we believe will result in solid long-term returns for our shareholders. In the fourth quarter, we modified the term of our $300 million preferred investment in NexPoint, trading yields for longer duration and additional managed properties.
We also continued our acquisition strategy, which focuses on asset-light structures, non-stabilized stores or acquisitions with long-term strategic implications, including Storage Express. While some of these initiatives caused short-term dilution, we believe they provide more total value for our shareholders over time and unlock additional growth channels for years to come.
Before handing the time over to Scott, I would also like to congratulate the Extra Space team for receiving our third consecutive Leader in the Light Award, NAREIT's highest ESG and sustainability honor for real estate companies. We are proud to be recognized as a REIT that delivers strong financial results and has also created a sustainable portfolio and company that is positioned to continue providing results for the long haul.
I'll turn the time over to Scott now.
