Demand for our facilities is also impacted by new supply of self-storage space and alternatives to self-storage.
Tenant reinsurance premium revenue generated from tenants at our Same-Store Facilities were $139.0 million and $133.9 million in 2022 and 2021, respectively, representing a 3.8% year over year increase in 2022. We expect future growth will come primarily from customers of newly acquired and developed facilities, as well as additional tenants at our existing unstabilized self-storage facilities.
Tenant reinsurance premium revenue generated from tenants at our Same-Store Facilities were $149.8 million and $144.4 million in 2023 and 2022, respectively, representing a 3.7% year over year increase in 2023. We expect future growth will come primarily from customers of newly acquired and developed facilities and the increase of tenant insurance participation at our same store facilities.
Our equity share of earnings from PSB contributed $57.7 million and $99.3 million to Core FFO in 2022 and 2021, respectively. As a result of closing the sale of PSB, we will no longer recognize equity in earnings from PSB in the future.
Our equity share of earnings from PSB contributed $57.7 million to Core FFO in 2022. Since the sale of PSB in July 2022, we no longer recognize equity in earnings from PSB.
We expect a moderate increase in other direct property costs in 2023 primarily driven by increase in credit card fees. Centralized management costs represents administrative and cash compensation expenses for shared general corporate functions to the extent their efforts are devoted to self-storage operations.

These amounts are net of $18.0 million, $17.4 million and $14.6 million in 2023, 2022 and 2021, respectively, in development costs that were capitalized to newly developed and redeveloped self-storage facilities. During 2023 and 2022, we wrote off $11.7 million and $7.0 million, respectively, of accumulated development costs for cancelled development and redevelopment projects.
The increase in 2021 is due primarily to (i) an 8.9% increase in realized annual rent per occupied square foot for 2021 as compared to 2020 and, to a lesser extent, (ii) a 1.9% increase in average occupancy for 2021 as compared to 2020.
The increase in 2023 is due primarily to (i) a 6.3% increase in realized annual rent per occupied square foot for 2023 as compared to 2022, partially offset by (ii) a 1.6% decrease in average occupancy for 2023 as compared to 2022.
Our developed facilities have thus far leased up as expected and are at various stages of their revenue stabilization periods. The actual annualized yields that we may achieve on these facilities upon stabilization will depend on many factors, including local and current market conditions in the vicinity of each property and the level of new and existing supply.

However, in the short run, our earnings are diluted during the construction and stabilization period due to the cost of capital to fund the development cost, as well as the related construction and development overhead expenses included in general and administrative expense. We typically underwrite new developments to stabilize at approximately an 8.0% NOI yield on cost.
