Insurance on a flip: builder’s risk, vacant dwelling and what the lender demands
The last document that holds up a fix-and-flip closing is rarely the appraisal. It is the insurance binder. A hard money lender is about to wire money against a vacant house that is going to be torn apart for four months, and it will not fund until a policy exists that covers that exact situation with the lender’s name printed on it. The policy most first-time flippers try to buy is the one that would not have paid.
Why a homeowners policy fails on a flip
A standard homeowners policy insures an owner-occupied dwelling, and two features of a flip break it.
Vacancy. Most personal policies suspend or exclude significant coverages — vandalism and malicious mischief, glass breakage, water damage from freezing, sometimes theft — once the dwelling has been vacant beyond a stated period, commonly 30 to 60 consecutive days. The house is not uninsured; it is insured for fewer perils than the ones that actually happen to empty houses. The number of days and the list of suspended perils differ by carrier and by state, so read the vacancy clause in the policy you are being offered rather than the summary in the quote.
Construction. Renovation work, materials in the garage and crews coming through the door are outside what a personal policy contemplates. An insurer that learns at claim time that the dwelling was gutted and empty is not obliged to invent coverage for it.
The three coverages a project actually needs
- Builder’s risk (also sold as course-of-construction or renovation coverage). Insures the structure and, when scheduled, materials on site and in transit, while work is under way. Written for the completed value of the structure, on a term that matches the project, and usually on a special-form (open perils) basis at the better end of the market.
- Vacant dwelling coverage. For the weeks when nothing is happening — after closing and before permits, or after the punch list and before the sale. Some carriers write it as a standalone vacant policy on a narrower named-perils basis; many now sell a single investor policy with a vacancy permit endorsement so the coverage does not switch off between phases. Ask which one you are buying.
- General liability. Someone gets hurt on your site. Limits of $1 million per occurrence and $2 million aggregate are the common market ask. This does not replace your contractors’ own liability and workers’ compensation coverage — collect certificates of insurance from every trade, naming your entity, before they start.
Depending on the property, add flood, separate wind or named-storm coverage in coastal states, ordinance-or-law coverage on older housing stock where a rebuild would have to meet current code, and a theft-of-materials sublimit large enough to matter — copper, HVAC condensers and new appliances leave job sites constantly.
What the lender puts in the loan agreement
Business-purpose bridge lenders are not bound by the agency rulebooks, but most of them borrow the same standards, and Fannie Mae’s property insurance requirements for one- to four-unit properties are a useful benchmark for what any institutional lender considers adequate. Expect the loan documents to require most of the following:
- Replacement cost valuation on the dwelling, not actual cash value — depreciated payouts do not rebuild a house.
- A coverage floor tied to the loan: coverage at least equal to the loan amount, or to the replacement cost of the improvements, with some programs asking for a cushion above the loan amount. Land is not insured, so a coverage figure built from the purchase price rather than construction cost is a common and expensive mistake in both directions.
- The lender named as mortgagee and loss payee, exactly as its entity name and address appear in the note, usually followed by ISAOA/ATIMA, plus additional insured status on the liability policy.
- A deductible cap, often in the $2,500 to $10,000 range, with percentage deductibles on wind or named storms limited separately.
- A paid-in-full policy term covering the loan term plus any extension, and advance notice to the lender before cancellation.
- Flood insurance where the property sits in a mapped special flood hazard area.
- The binder before funding. Not the application, not the quote — the bound policy or binder, at or before closing.
If coverage lapses mid-project, the lender may force-place a policy at a price well above the market and add it to your balance. Force-placed coverage protects the lender’s interest, not your equity and not your liability, and a lapse is itself a default under most loan agreements — see what happens in a hard money default.
Indicative costs
Insurance is priced on the completed value of the structure, the scope of work, the construction type, the location and your claims history. Brokers commonly quote renovation projects on a rate per $1,000 of completed value, and rehab prices higher than ground-up work because an existing structure can burn on day one:
| Coverage | Indicative market range | On a project with $250,000 of completed structure value |
|---|---|---|
| Builder’s risk, renovation of an existing house | roughly $3.50–$5.50 per $1,000 of completed value | about $900–$1,400 for a 6–12 month term |
| Builder’s risk, ground-up construction | roughly $1.00–$2.50 per $1,000 | about $250–$625 |
| Vacant dwelling, no active work | priced above a landlord policy on the same house | a few hundred dollars per quarter |
| General liability, $1M/$2M | $500–$1,500 a year for a small investor | $500–$1,500 |
| Flood, mapped high-risk zone | highly location-specific | verify with a quote, not an estimate |
These are indicative market observations, not quotes, and premiums have moved sharply in catastrophe-exposed states. Budget $1,500 to $3,000 for a typical single-family flip and get real quotes early: a coastal or wildfire-exposed property can cost several times that, and occasionally cannot be placed in the admitted market at all. The number belongs in your carrying costs, listed in full in our guide to fix-and-flip financing.
Flood: the waiting period and the closing exception
The National Flood Insurance Program applies a standard 30-day waiting period before a new policy takes effect, which would make a normal purchase impossible in a flood zone. The waiting period does not apply when flood insurance is purchased in connection with the making, increasing, extending or renewing of a loan — coverage can be effective at closing. Private flood carriers set their own rules and often bind faster. Whether coverage is required at all is a federal question tied to the flood zone and the lender, explained on our page on the Flood Disaster Protection Act; the map, not your opinion of the terrain, decides.
Five ways a claim gets denied
- Vacancy was not disclosed. The single most common denial on investor property. If the house is empty, the policy has to know it.
- The work exceeded the described scope. Structural work insured as a cosmetic refresh, or a permit that was never pulled, gives the carrier a reason to look harder at everything else.
- Freeze damage with the utilities off. Many policies carry a heat-maintenance or winterization warranty. A burst supply line in an unheated house in January is a routine, avoidable, uncovered loss.
- Underinsurance and coinsurance. Insuring to the loan amount when replacement cost is higher can reduce a partial-loss payout proportionally, not just cap the total.
- The policy was never updated. The house sold, or it was rented instead of sold, and the builder’s risk policy still describes a construction project. Occupancy changes have to be reported.
Claude Loan is an information site — not an insurance agency, broker, lender or adviser, and nothing here is a quote or a promise of coverage. Policy language, vacancy periods and state availability vary enormously; the only terms that bind you are the ones in your own policy and loan agreement. An independent agent who writes investor property routinely is worth a call before you go hard on earnest money, not after. Draw mechanics are covered in rehab draws, and the loan rules themselves on our hard money state pages.
Frequently asked questions
Does the lender’s mortgagee clause protect me too?
No. The mortgagee or loss payee clause directs claim proceeds toward the lender’s interest in the property up to the balance owed. Your equity, your rehab spend and your liability exposure are protected only by the coverage you buy in your own name — and on a partial loss the lender may hold the proceeds and release them in draws as repairs are completed, which is worth knowing before it happens.
Can I rely on my contractor’s insurance?
No. A general contractor’s liability policy responds to that contractor’s negligence; it does not insure your building against fire, and workers’ compensation covers their crew, not your structure. Collect certificates from every trade anyway — uninsured subcontractors can leave your general liability policy responding to an injury you did not cause, and lenders on ground-up projects generally require proof of both.
How much coverage should the policy actually carry?
Enough to rebuild the structure at current construction costs, which is neither the purchase price (it includes land) nor the after-repair value (it includes the market). On a rehab, the usual approach is the completed value of the improvements: as-is structure value plus the renovation budget. If the lender’s minimum is higher than that figure, the lender’s minimum wins.
What happens if the flip takes longer than the policy term?
Builder’s risk is written for a defined term and frequently allows an extension for an additional premium if it is requested before expiration. Requested after expiration, it is a new policy with new underwriting, and any loss in the gap is yours. Put the policy expiry date on the same calendar as the loan maturity and the extension deadline; projects that run long tend to run long on every deadline at once.
