Well, thank you, Jason, and welcome to our fourth quarter call. With me today are Kevin O'Shea, Sean Breslin and Matt Birenbaum. Sean, Kevin and I will provide some comments on the slides that we posted last night, and then all of us will be available for Q&A afterwards. Our comments will focus on providing a summary of Q4 and the full year results and a discussion of our outlook for 2020.
Starting on Slide 4. Highlights for the quarter and the year include core FFO growth of 5.2% in Q4 and 3.8% for the full year. Same-store revenue growth came in at 2.5% for the quarter and 2.8% when you include redevelopment. Full year same-store revenue growth came in at 2.9% or 3.1% including redevelopment. We completed $335 million of new development in Q4 and $665 million for the year at a 6.5% yield and started just under $800 million last year. And lastly, we raised $1.3 billion in external capital for the year in a mix of asset sales, new debt net of redemptions and common equity at an average initial cost of 4.3%.
The next few slides will provide a little more detail on 2019 performance and provide context for our 2020 outlook.
Turning first to Slide 5. During the year, we saw the East Coast surpass the West Coast in rent growth for the first time in 8 years. In Q4, the East outpaced the West by over 100 basis points led by Boston and the D.C. Metro area, while we experienced some softening conditions in California.
Turning now to Slide 6. Development continued to be a big contributor to NAV growth in 2019. Development completions of $665 million created approximately $300 million in incremental value and, at 30% margins, remain very healthy 10 years into the expansion.
Moving now to Slides 7 and 8. We made good progress in Southeast Florida and Denver over the last year, our expansion markets. To date, we've committed roughly $600 million to each market through a combination of acquisitions, development and partnering with local developers. These portfolios are comprised of new assets and, as you can see from the maps on Slides 7 and 8, are spread across a broad geography within the markets.
Turning now to Slide 9. We believe to be a great company, we need to take a multi-stakeholder approach to our business. We can only deliver strong financial results over a sustained period of time by having engaged associates, satisfied customers and the support of local communities by taking an active leadership role in addressing important environmental and social challenges. And while we always strive to be better, we've been recognized for doing a good job in many of these areas over the past year. And starting with our associates as engagement scores were in the top decile, and we were named in the Glassdoor's list of Top 100 Best Places to Work for the second consecutive year in 2019; with our customers as we ranked #1 nationally among apartment REITs by Online Reputation for the fourth consecutive year; and then lastly, with our communities where our efforts on the ESG front have been recognized by several organizations, including GRESB, who recognized AVB as the U.S. and global leader in the residential sector; by the Carbon Disclosure Project, or CDP, international organization that grades companies on their carbon emissions disclosure practices across all industries and who recently awarded AVB a grade of A-, 1 of 4 REITs and the only apartment company to receive such a grade; by the Science-Based Targets Initiative, who reviewed and approved AVB's submittal for targeted reduction in carbon emissions by 2030. We are 1 of 11 real estate companies globally and 1 of 5 REITs that have completed this process; and lastly, by CR Magazine, who ranked AVB in the top 100 corporate citizens globally for the second consecutive year out of a universe of over 1,000 companies.
Turning now to Slide 10. Now that the calendar has turned to 2020, we thought it made sense to look back on our performance over the last decade. In short, it's been a great decade and cycle for the apartment sector and for AvalonBay. Buoyed by strong demand fundamentals and attractive capital market conditions, we have seen healthy growth in earnings and NAV since 2010.
For AVB, core FFO growth has averaged 10% on a compounded annual basis since 2010 or about 200 basis points above the sector. The absolute level of growth has been fueled by both strong internal growth, as same-store revenue growth has averaged over 4%; and as can be seen on Slide 11, by strong external growth, mainly from contributions to new development as we consistently delivered new development at initial yields well above the marginal cost of capital and roughly 200 basis points above prevailing cap rates.
As you can see on the right-hand side of the slide, development deliveries since 2010 of just over $8 billion have generated more than $3 billion in initial value creation or roughly $26 per share.
Turning now to our outlook for 2020 on Slide 12. We're projecting core FFO growth of just over 5% this year mainly from a combination of same-store NOI growth of 3% and from stabilized new development, which is expected to generate more than $60 million in NOI in 2020.
Turning to Slide 13 and double-clicking on this a bit. The stabilized portfolio is expected to contribute roughly 3.5% of total core FFO growth in 2020. External growth or NOI from new investment net of capital costs is expected to contribute 2.7%. And overhead growth and loss of JV and fund income will actually provide a drag of about 110 basis points to growth, with about 1/3 of that 110 basis points coming from a loss of JV and fund fee income, about 1/3 from normal overhead growth in our base business and the remaining 1/3 coming from expensed overhead that represents investment in innovation or other overhead that is projected to generate future ROI, some of which we will benefit from in 2020.
At 5.1%, the level of core FFO growth is expected to be 130 bps higher than 2019. The biggest driver for this is stronger external growth of roughly 200 basis points on a net basis driven by higher levels of deliveries in late 2019 and 2020 as well as a lower cost of capital raised last year. This is offset in part by the headwind from the loss of JV and fund income as we wind these vehicles down.
Turning to Slide 14. This slide provides a summary of the key economic factors driving much of our outlook. I won't go through everything here but simply say while the GDP and job growth is expected to moderate from 2019, the strength of the consumer should provide a tailwind with tight labor markets, rising wages, healthy balance sheets, bolstering confidence, healthy consumption and household formation. The business sector is expected to provide more crosswinds in 2020 versus 2019 as sluggish business investment should be offset in part by less concern surrounding a potential trade war. And lastly, the government sector should bolster the economy in 2020 as the lack of fiscal constraint and an accommodative Fed should provide added support to economic growth.
So overall, it's shaping up as a good macro backdrop to support the economy and the housing sector for the year ahead.
I'll now turn it over to Sean who will provide more color on our outlook for the portfolio.
