Economic Downturn Sensitivity: Rental income and property valuations for AvalonBay Communities are highly sensitive to overall economic conditions, including employment levels, wage growth, and consumer confidence, which can lead to reduced demand for apartments, higher vacancy rates, and slower rental growth or even declines in their markets.

Interest Rate Volatility: Rising interest rates can significantly increase AvalonBay's borrowing costs for new acquisitions and development projects, potentially reduce property valuations by compressing capitalization rates, and negatively impact the overall cost of capital and profitability.

Market Competition and Supply: AvalonBay operates in highly competitive urban and suburban markets that are subject to substantial new apartment supply from competitors, which can lead to increased vacancy, slower rent growth, or rent decreases as tenants have more options, impacting financial performance.
