When Insurance Enters Your Purchase
Start requesting quotes as soon as you are seriously considering a property — not after your offer is accepted. Insurance availability and terms are part of what makes a home workable, and you want that information while you still have room to negotiate.
A signed binder is required before closing, the policy goes into effect at closing, and your lender needs proof of coverage in hand before it will fund the loan. A binder is simply the insurer's written confirmation that coverage is in place as of a specific date.
Insurance shopping is not a step to leave until the last week. If quotes come back slowly, or a carrier asks for an inspection you have not scheduled, it can affect whether your deal closes on time.
