Builder's risk insurance for house flippers: the complete guide

Every flip carries two timelines: the one in your pro forma, and the one where the city inspector reschedules twice and your cabinet order arrives broken. Builder's risk insurance is what keeps the second timeline from becoming a financial disaster — it's the policy that covers an investment property while it's vacant, gutted, and full of expensive materials.

What builder's risk insurance covers

A builder's risk policy (sometimes called course-of-construction insurance) covers a structure while it's being built or renovated. For a flipper, the policy typically protects three things:

• The structure itself — against fire, lightning, wind, hail, and similar perils, at its completed value.
• Materials and fixtures — lumber, cabinets, appliances, HVAC equipment — whether installed, stored on site, or in transit to the job.
• Vandalism and theft — the most common claims on vacant job sites, from stolen copper to broken windows.

Most investor policies pair this with premises liability, which covers injuries to third parties at the property — a neighbor's kid wandering onto the site, an appraiser tripping on debris. Limits of $1 million per occurrence are standard; $2 million is available.

Why flippers can't use a regular policy

Homeowners and landlord policies are written for occupied homes in stable condition. A flip violates both assumptions. Nearly every standard policy contains a vacancy clause that restricts coverage once the home is empty for 30–60 days, and most exclude properties under renovation outright. The result: investors who "save money" by keeping the seller's old policy are usually carrying paper that won't pay.

What builder's risk costs

Pricing depends on five inputs, roughly in order of impact:

Because terms are short and the structure is the main exposure, most flippers find builder's risk costs less than they assumed — and far less than one month of holding costs on a stalled, uninsured project. The only way to know your number is to quote the actual property.

What your hard-money lender will require

If you're borrowing, the lender drives the insurance checklist. Expect them to require:

• A builder's risk policy with a dwelling limit at or above the loan amount (often the full completed value).
• The lender named as mortgagee / loss payee on the policy.
• Liability coverage, commonly $1M per occurrence.
• Proof of insurance before funding — usually as a condition of closing.

This is where speed matters. A quote that takes a week can push a closing; Lumin policies can be bound in as little as one day, with the certificate sent directly to your lender or title company.

Five gaps that catch flippers off guard

1. The gap before demo day. You closed three weeks ago; permits are pending. Builder's risk may not have started yet, and the home is vacant. A short vacant property policy bridges it.
2. The project that runs long. Policies have terms; projects have delays. Extend before expiration, not after — a lapsed policy can't be reinstated retroactively.
3. The contractor without insurance. Your builder's risk doesn't cover your GC's workers. Always collect certificates of general liability and workers' comp before crews start.
4. The finished flip sitting on market. When renovation ends, builder's risk ends its job. If the sale takes months, you're back in vacant territory.
5. The flip that becomes a rental. BRRRR investors need the handoff to a landlord policy the day the tenant gets keys — not at the next renewal.

How to buy it without slowing your deal

Have four things ready when you quote: the address, your rehab budget and scope, your expected timeline, and your lender's insurance requirements (they'll email you a one-pager if you ask). With those in hand, an online quote takes about four minutes — and you can have the policy bound and the certificate in your lender's inbox before your next draw inspection.
