🛡️ Renters Insurance — Estimated Cost

Based on what Colorado renters actually paid: NAIC industry data for 2023 (average HO-4 premium, 555,939 policy-years), adjusted to July 2026 with the U.S. Bureau of Labor Statistics tenants' insurance index. It is a market average, not a price for this building and not a price for you.

Your own price depends most on your credit-based insurance score, your claims history and which carrier you choose. In published Ohio figures the same coverage ranges from $127 a year at excellent credit to $933 at poor credit. We do not ask for any of that, so we cannot narrow this for you.
