Nuclear refurbishment could bring a new cycle of project-related accommodation demand from 2027, while Seaton's school and recreation investments arrive on separate schedules. That mismatch favours a closer look at existing rental homes and practical commutes before assuming the benefits will flow first into new family-home sales.",
