Price-to-earnings of 108.6x for Sun Communities: Is it justified?
On a P/E basis, Sun Communities trades at 108.6x earnings, which is high relative to both its recent share price softness and its sector peers.
The P/E ratio compares the company’s share price to its earnings per share. For a residential REIT like Sun Communities, this multiple reflects how much investors are currently prepared to pay for each dollar of earnings, often influenced by expectations around income stability, growth in funds from operations and asset quality.
In Sun Communities' case, several factors sit behind this elevated multiple. The company only became profitable over the last year and its reported earnings carry large one off items, including a loss of $240.3m in the last 12 months to 30 June 2026 that affects the quality of historic results. Earnings are also forecast to grow 41.5% per year and are expected to grow significantly over the next 3 years, which can support a richer multiple, although current return on equity of 2% is considered low and is forecast to remain below typical high return thresholds in 3 years' time. Analysts’ target price is described as relatively close to the current share price, with the target less than 20% higher, which suggests only a modest upside implied by that reference point.
The comparison with peers is where the premium becomes clearest. Sun Communities' P/E of 108.6x is materially higher than the Global Residential REITs industry average of 20.6x and well above the peer average of 54.2x. It is also expensive compared to an estimated fair P/E of 61.4x, a level that regression analysis suggests the market could move towards if expectations normalise or if earnings track closer to sector norms.

Result: Price-to-earnings of 108.6x (OVERVALUED)
However, Sun Communities still faces risks if earnings quality remains distorted by one off items or if the Global Residential REITs valuation gap starts to close.
