Summary

Climate risk scores are becoming a major factor in real estate, influencing insurance costs and potentially impacting investor profits. Hosts in high-risk areas could face higher insurance premiums and difficulty securing coverage. Hosts should assess their climate risk, consider property upgrades, and work with experienced insurance brokers.
