All right. Thanks, Tim. Turning to Slide 6. We experienced a year-over-year increase in prospect visits to our communities each month of the quarter. In total, visit volume was up about 20% year-over-year during Q3, which led to a roughly 10% increase in net lease volume. As you can see from Chart 2 on Slide 6, the most significant increase in net lease volume occurred in September, which is up about 35% year-over-year. And as of yesterday, traffic and leasing volume for October was up roughly 25% and 20%, respectively.
Moving to Slide 7. For the first time in more than 4 years, resident notices to vacate our communities increased by a meaningful amount on a year-over-year basis. During Q3, notices increased by roughly 17%, primarily as a result of the spike in lease terminations in urban submarkets, which is depicted by the hash bars on Chart 1 on Slide 7 and a topic I'll touch on in a minute.
Our leasing volume exceeded the pace of notices, however, starting in August and has continued through October. As a result, if you turn to Slide 8, you can see that beginning in September, move-ins exceeded move-outs and physical occupancy has increased from the low point at 93.1% in September to 93.5% for October and stands at 93.9% today.
Moving to Slide 9. Our suburban portfolio continues to perform substantially better than our urban assets. Charts 1 and 2 at the top of Slide 9 reflect notices to vacate our communities and lease terminations by submarket type. Notices to vacate our urban communities increased by roughly 40% during the quarter, driven by an approximately 70% increase in lease terminations, and led to a 340 basis point decline in physical occupancy from Q2 to 90.2% and double-digit decline in rent change. For our suburban portfolio, the increase in notices to vacate was more modest, supporting better physical occupancy and rent change.
The performance of our urban portfolio has been impacted by a variety of factors, including those mentioned by Tim in his prepared remarks. I'd highlight the combination of extended work-from-home policies and the civil unrest that occurred during the summer months, which impacted the quality of urban environments, is key factors driving residents to break leases during Q3 and leave urban centers for housing options and other geographies.
Shifting to Slide 10 to address regional performance. Increased turnover in Northern California, the Mid-Atlantic and New York/New Jersey impacted physical occupancy more than in other regions. In the New York/New Jersey region, the increase in turnover was primarily a function of elevated turnover in New York City, which is 87% on an annualized basis during the quarter. For the Mid-Atlantic, we experienced increased turnover in the District of Columbia and other urban or quasi-urban submarkets like the Rosslyn, Ballston and Tysons Corner submarkets in Northern Virginia.
In Northern California, annualized turnover during Q3 was 85%, driven by elevated turnover across all 3 markets, San Francisco, San Jose and the East Bay, but was most pronounced in San Francisco and in Mountain View where Google is headquartered.
On a positive note, turnover was relatively flat in New England, which is a testament to our primarily suburban Boston portfolio and was down in both Pacific Northwest and Southern California. Physical occupancy in all 3 regions exceeded the portfolio average.
And moving lastly to Slide 11. Same-store like-term lease rent change was down 3.3%, and effective rent change was down 5.8%. Metro New York/New Jersey and Northern California are 2 of the regions I identified on the last slide with elevated turnover and, therefore, available inventory to lease produced the weakest rent change during the quarter. Rent change in New England held up the best, again, supported by our suburban Boston portfolio, which, in many cases, offers differentiated products, including larger unit sizes to those departing urban environments.
So with that, I'll turn it over to Matt to address our development portfolio.
