Joseph Daniel Margolis
Chief Executive Officer at Extra Space Storage
Thanks, Jared, and thank you, everyone, for joining today's call. As many of you know, Jeff Norman has transitioned into another role within the organization as the Head of Treasury and Capital Markets. Many of you on this call have worked with Jeff and experienced his professionalism, responsiveness, fast knowledge and good nature. I recognize and appreciate his efforts to make Extra Space a leader in the industry, and look forward to his continued contribution to the company. I would also like to introduce Jared Conley, our new Vice President of Investor Relations. Jared has been with Extra Space since 2002 and has worked in various roles, most recently as our Head of Financial Planning and Analysis. We look forward to introducing him in person next month at NAREIT. Turning to this quarter's performance.
We have seen sequential improvement in occupancy and rate since our fourth quarter earnings call in late February. Operationally, occupancy at the Extra Space same-store pool grew every month during a period normally recognized for seasonal declines, ending the quarter at 93.2%, a 50 basis point increase year-over-year. Our revenue strategy has allowed us to both improve occupancy and average move-in rate in the quarter, with the latter growing sequentially by approximately 8% from a seasonal low in January. The combination of improving move-in rate, higher occupancy, and steady existing customer rate increases have provided a 1% lift in Extra Space's same-store revenue performance, which is in line with our internal projections. Also, as expected, Extra Space same-store expense growth increased by 5.5% year-over-year. The legacy Life Storage same-store pool performance continues to improve, outpacing the Extra Space same-store properties.
Revenue gained 1.7% year-over-year, which was in line with internal projections and against the backdrop of a difficult comp, where prior management pushed hard on rates in 2023 at the expense of occupancy. Occupancy at our Life Storage improved to 92%, a 220 basis point improvement over last year, narrowing the gap between pools to 120 basis points at quarter end. At the end of April, this gap, which was over 400 basis points in closing, has further narrowed to 90 basis points on our platform. To do so, we have maintained lower rates through the quarter with the strategy of higher occupancy, leading to stronger new and existing customer rates through the remainder of the year. We believe improved rate performance will continue to lift these properties and ultimately bring them to parity with legacy Extra Space store rate and occupancy levels. Life Storage same-store expenses increased 6.7% year-over-year, also due to an exceptionally hard 2023 comparable, but below internal projections.
Expenses increased particularly in the areas of payroll and repairs and maintenance, as we address areas that were underinvested at this time last year. On the external growth front, the transaction market continues to be muted. However, we expanded our capital-light external growth activities, adding $164 million in new bridge loans meaningfully ahead of our projections. In addition, we added 97 third-party managed stores gross and 72 stores net. We continue to have the fastest-growing third-party management platform in the industry. Overall, the year is unfolding as expected with wins in capital-light growth and G&A and expense savings. We are working hard and I am confident of our teams and infrastructure are well prepared to optimize performance during the important upcoming leasing season.
I will now turn the time over to Scott.
