Thank you, Tammy. Yesterday afternoon, we reported core FFO per share of $0.44, which represents an increase of 10% over the prior year period. As Tammy mentioned, this growth was fueled by a combination of strong acquisition volume over the past year and accretion from the internalization of SecurCare.
For the third quarter, same-store NOI increased by 0.2% over prior year, driven by flat same-store revenues and a 0.4% decline in property operating expenses.
Same-store occupancy averaged 91.1% during the third quarter, an increase of 100 basis points compared to the same period in 2019. This occupancy improvement was offset by an average rental revenue per occupied square foot that decreased 1.4% year-over-year. One nuance to point out is that the rental revenue per square foot metric includes auction, admin and late fees, which accounted for approximately 90 basis points of that decline, with the remainder attributable to rental rate declines.
Similar to last quarter, same-store OpEx growth benefited from diligent cost control measures across the board. Specifically, personnel costs declined 2.7% as we optimize staffing hours early in the quarter, with those expenses starting to normalize toward the end of the quarter. Utilities declined 4%, partially attributable to the benefits from our LED lighting initiative. And repairs and maintenance costs decreased 2.4%. These favorable expense controls were partially offset by property taxes that grew 2.2% from the prior year period.
Next, let me give some color on the positive trends that continued in October. Move-in volume continued to be higher year-over-year, while move-outs continue to be lower, which drove same-store occupancy at the end of October to 92.4%, which is up 420 basis points compared to the end of October 2019, and up 50 basis points sequentially from the end of September. This is an all-time high level of occupancy for our same-store portfolio.
As for Street rates, they turned positive in October, just under 1% year-over-year versus down about 3% in Q3. Our customer acquisition strategies are clearly proving effective at capturing demand while we remain disciplined on starting rate and discounts.
Now as Tammy noted, with only 1 quarter of the year remaining, we've reinstated full year 2020 guidance, which includes positive growth for both revenue and NOI in our same-store pool. For full year 2020, we expect the following: core FFO per share of $166 to $168 or 8.4% growth over prior year at the midpoint; same-store revenue growth of 0.75% to 1.25%; OpEx growth of 1.5% to 2%; NOI growth of 0.25% to 1%; and wholly owned acquisitions of $400 million to $500 million. Additional guidance assumptions are outlined in our earnings release.
I would like to highlight that we have a challenging year-over-year expense comp in the fourth quarter, primarily due to favorable property tax adjustments last year, which will mute same-store NOI growth for the quarter. But importantly, midpoint of our revenue range implies growth of over 2% for the fourth quarter. These positive expectations should set us up well for continued strong performance in 2021, assuming the current fundamental recovery is not derailed by a resurgence of COVID infections or material impacts on our business from the economic recession.
Now turning to the balance sheet. In September, we entered into an equity forward sale agreement to issue 4.9 million common shares for proceeds of approximately $160 million. We have 6 months from the time of the agreement to settle the forward and we plan to use proceeds primarily to fund acquisitions.
Further evidencing our access to multiple sources of capital, during the third quarter, we issued 182,000 shares of common stock through our ATM program at an average price of $34.36 per share for gross proceeds of $6.3 million. We also issued $3.4 million of OP and SP units in connection with our acquisition activity.
Subsequent to quarter end, we funded our previously announced $250 million private placement, which extends our weighted average maturity to 6 years, lowers our average fixed rate borrowing cost, and replenishes the capacity on our $500 million revolver. Our balance sheet is well positioned with only $4 million of debt maturing through 2022, healthy access to multiple sources of capital, and a net debt-to-EBITDA ratio of 6.0x at the end of the third quarter, down from 6.3x at the end of the second quarter.
The strength and flexibility of our balance sheet positions us well to take advantage of the pickup in acquisition activity we're seeing.
We remain committed to delivering our investors stable cash flow from an outstanding property type combined with disciplined external growth through accretive acquisitions.
