Joseph D. Russell
President, Chief Executive Officer at Public Storage
Thank you, Ryan, and thank you all for joining us today. Tom and I will walk you through a few highlights for Q3 and then open up the call for questions.
Each team at Public Storage is successfully exercising our platform-wide advantages in a more competitive environment as demonstrated by third quarter performance and our raised outlook for the remainder of 2023. As we entered this year unexpectedly, we saw new move and customer demand for the sector shift lower, particularly with softening, existing home sales due to the rapid rise in home mortgage rates.
On the flip side, there has been solid and increased demand from new customers that are renters. They have proven to be very good customers as well, particularly from a length of stay perspective. We have the right team, technologies, and analytics to determine the appropriate mix of marketing, promotions, and rental rates. Drawn by these top-of-funnel tools, along with our leading brand, self-storage users are clearly choosing Public Storage. Our strong move-in volume coupled with healthy in-place customer behavior has led to better-than-expected occupancy trends with our same-store occupancy gap narrowing from 250 basis points at the beginning of the year to 120 basis points at the end of September and to 60 basis points, as of today.
Our digital and operating model transformation continues to be a significant enhancement to customer experience and our financial profile. Customers benefit from having digital options at their fingertips across their entire journey. Our proprietary digital ecosystem is a compelling reason to choose us with over 60% of our customers running through our online leasing platform. And today we have more than 1.4 million PS app users and our financial profile benefits as well. We are putting these digital tools in the hands of our customers and employees for convenience combined with in-person onsite customer service, when and where it is needed. The result is a better customer experience and enhanced margins, particularly in regard to labor efficiencies.
We are also growing our portfolio amidst broader market dislocation. Our industry-leading NOI margins, multi-factor in-house operating platform, access and cost-of-capital, and growth-oriented balance sheet put us in a very unique position. So far this year, we have acquired more than $2.6 billion worth of properties, including the $2.2 billion simply self-storage portfolio comprising 127 properties. As is our regular practice every property was fully integrated into the Public Storage platform on day one and we welcomed over 50 new associates and approximately 90,000 customers.
We are also ahead of schedule on re-imaging the entire portfolio to Public Storage to ensure the maximum benefit from our industry-leading brand. We will have also delivered $375 million in development by year-end and have a pipeline of nearly $11 billion of development to be delivered over the next two years. Since we updated you last quarter, the sharp move-in interest rates has backed up the acquisition market with fewer deals likely to trade by year-end, typically a busy time of year for asset closings. We are actively engaged with a full range of owners that give us confidence that some sellers' expectations will adjust as the cost of capital has clearly increased.
Our advantages enable us to acquire and develop when others can't. We have a strong appetite to grow our portfolio as seller expectations continue to correct and we have a matching ability to execute.
Now, I will turn the call over to Tom.
