Joe Margolis
Chief Executive Officer at Extra Space Storage
Thanks, Jeff, and thank you everyone for joining today's call. We had a busy third-quarter. In July, we successfully completed our merger with Life Storage, adding over 1200 stores to our portfolio and over 2300 new members to the team Extra Space. The transition is going very smoothly and I'm proud of the teamwork and innovation our employees are demonstrating through the merger. Our combined portfolio of 3,651 stores provides greater diversification stability revenue opportunities and operational efficiencies that I believe will improve our property-level and external growth for years to come. From a performance standpoint, the third quarter was generally in-line with expectations.
Revenue growth moderation for the Extra Space same-store pool flattened meaningfully during the third-quarter and our 1.9% same-store revenue increase was modestly ahead of our expectations. Revenue growth was driven by high average occupancy in the quarter of 94.4%. Existing customer behavior continued to be strong with solid length of stay muted vacate and continued acceptance of rate increases. Rental volume was also steady Year-over-Year, albeit at lower new customer rates. Expenses came in higher than our estimates offsetting the revenue outperformance. This was driven by higher-than-expected property tax increases. The higher-than-projected expenses resulted in a modest miss in our same-store NOI, which was offset by a beat in G&A resulting in core FFO of $2.02, this was in-line with our internal forecast.
Short-term dilution from the merger with LSI was consistent with our estimates for the third-quarter. We have achieved our target G&A synergy run-rate of $23 million and we'll continue to gain additional synergies as we further integrate the team platform and portfolio. We have also started to realize property-level revenue synergies as we move existing LSI customers to rates more consistent with the Extra Space portfolio. The incremental FFO contribution from these improvements is partially offset initially by lower occupancy at the LSI properties due to catch-up auctions and lower new customer rates to drive rental demand. However, once we achieve stronger new customer rates and build occupancy the benefit to FFO will ramp-up and we remain confident we will reach our total expected synergy run-rate in the first-quarter of 2024. We have slowed our acquisition pace given the LSI merger, but we continue to be very active in third-party management adding 49 new stores, gross in the third quarter, not including the LSI managed stores.
Year-to-date, outside of the LSI merger, we have added 151 stores gross to the managed platform with only 17 departures. We have also continued to have steady bridge loan volume, despite the difficult interest-rate environment. In short, property-level performance is in-line with expectations. The integration of the Life Storage properties is on-track and we continue to be active in our capital-light external growth channels. As a result, we have tightened our annual core FFO guidance for 2023, maintaining the same midpoint. We will remain focused on maximizing performance at all of our stores and executing our integration plan in the fourth-quarter. As we have interacted with our shareholders throughout the quarter, it has been hard to miss the serious concerns people have about wars, the economy, interest rates, consumer health sector demand and our stock price. We absolutely share those concerns. That's said I think it is important to step-back and not lose sight of where we stand today.
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. Occupancy averaged over 94% in the quarter and it remains very healthy. New customer rates will not as strong as last year remained 20% higher than 2019 pre-pandemic levels and customer health remained strong. New supply continues to moderate and the headwinds to future new development are substantial and increasing.
Our external growth drivers continue to fire on all cylinders and I am confident in our ability to further scale our platform. And finally, I believe we have the strongest team and operating platform in the industry. It is still a great time to be in Storage and I believe the future of Extra Space remains very bright. I will now turn the time over to Scott.
