Insurance Binder
Temporary written proof of coverage issued before the full policy is printed — what most closings actually require to fund.
An insurance binder is a short document a carrier or agent issues confirming coverage is in force, before the full policy document itself is issued. It's a legally binding temporary contract, typically valid for 30–90 days, and it's what most mortgage closings actually accept as proof of insurance to fund the loan — the full policy usually arrives afterward.
Why it matters
- "Bindable" and "insurable" aren't the same question — a property can be technically insurable in principle while no carrier is currently willing to bind a policy on it before closing.
- A lender needs the binder (or equivalent proof) days before closing, not at closing — leaving it until the final week is the single most common way an otherwise-ready deal stalls.
- A binder can be cancelled or non-renewed just like a full policy if underwriting later declines to issue the full policy — it's not an unconditional guarantee.

Non-Renewal
A carrier's decision not to renew a policy at its next term — distinct from a cancellation, and the leading edge of a market pulling back from a geography.
Insurability
Whether a property can realistically be insured at all, and how hard that placement will be — a distinct question from what it will cost.
