Joseph D. Margolis
Chief Executive Officer at Extra Space Storage
Thanks, Jeff, and thank you, everyone, for joining today's call. We had a solid fourth quarter where we focused on optimizing the performance of the recently added Life Storage assets while maximizing the performance of the legacy Extra Space locations. We were also very productive on the external growth front, adding another 74 third-party managed stores, eight stores through acquisition and $129 million in bridge loans. Operationally, the Extra Space same-store pool maintained high occupancy and solid in place rents, driving same-store revenue growth of 0.8% for the quarter. Core FFO in the quarter was $2.02 a share and full year core FFO was $8.10 per share.
On our last call, we outlined that in order to reach the high end of our guidance range, we would need achieved rates to new customers to improve on a year-over-year basis. While demand was steady and allowed us to maintain strong occupancy, it was not strong enough to eliminate negative new customer rates, which remained at approximately negative 10% during the quarter. As a result, we faced the headwind of higher negative churn and our full year performance was near the midpoints of our same store and FFO ranges.
Turning to Life Storage. One of the factors in our merger decision was our belief that we could enhance Life Storage property performance through our more sophisticated platform. Seven months removed from closing, we are happy to report that our assumptions have proved true. Customer acceptance of rent increases has been in line with our expectations, and we are seeing the net rent per square foot for legacy Life Storage customers move closer to that of nearby Extra Space locations. Occupancy is also responding positively, and we saw the occupancy gap between the LSI and Extra Space Storage same-store pools tightened through the quarter, improving from a gap of 350 basis points at the beginning of the fourth quarter to a gap of 250 basis points at year end. Today, that gap has tightened further and is approximately 200 basis points.
The occupancy improvement, together with the benefit of existing customer rent increases resulted in legacy LSI same-store revenue growth of 1.8%, an acceleration of 80 basis points over the third quarter growth rate. However, similar to the Extra Space properties, we continue to see new customer price sensitivity at the Life Storage locations, resulting in lower-than-anticipated new customer rates. So while we are achieving the anticipated incremental outperformance we expected for the Life Storage assets, reaching full property level synergies is taking longer than anticipated due to current market conditions, which we know will eventually normalize.
The current level of demand also influences our outlook for 2024. We are encouraged by our rental velocity, occupancy levels, existing customer health, length of stay, and the potential benefits of moderating new supply. However, these factors have not yet led to material improvement in new customer rates. We are confident we can hold strong occupancy and generally maintain current revenue levels, but we believe it will be difficult to drive a reacceleration in revenue growth until we regain pricing power with new customers.
We are seeing some positive signs that we are getting closer. And given our strong occupancy levels when pricing power returns, we are very well positioned to push rates quickly. We just have not seen enough progress to date to feel confident this inflection will be in time for the 2024 leasing season, or to include this scenario in our guidance.
So, while the industry as a whole will likely face headwinds from lower new customer rates in the near term, the long-term outlook for our sector and for Extra Space specifically remain bright. Storage has consistently proven to be a remarkably durable asset class and Extra Space Storage has the largest and most diverse portfolio in the industry. New supply continues to moderate and the headwinds to future new development are substantial and increasing.
We have very strong third-party management and bridge loan pipelines and a robust joint venture program, and I am confident in our ability to further scale our capital-light growth activities. We expect outsized relative growth from our LSI assets in 2024, with additional synergies to be unlocked as the rental environment improves. And as I mentioned, our occupancy today is over 93% at what is normally our low point for the year. Once demand improves, we are very well positioned to capture it.
I will now turn the time over to Scott.
