Every fix and flip loan requires insurance, and most investors treat it as a box to check before closing. Then a claim happens, a burst pipe floods the subfloor or a fire starts in a half-finished kitchen, and they discover the landlord policy they bought does not cover a property under renovation, or the standard homeowner policy they carried over from the seller was voided the moment the house went vacant. The insurance a flip actually needs is not the insurance a rental needs, and buying the wrong one is a mistake that stays invisible until the day you need to file. This guide walks through builder’s risk and vacant-property insurance on a fix and flip loan in 2026, why lenders require it, what it costs, and how to avoid the coverage gap that catches investors mid-rehab.
We arrange fix and flip and bridge loans for investors across Pennsylvania and additional states, and insurance is one of the closing conditions that quietly stalls deals when it is wrong. The property is under contract, the loan is approved, and then the insurance binder comes in as a standard homeowner policy that the lender rejects because it does not cover a vacant home under construction. Understanding what the right policy looks like before you shop for it keeps the coverage from becoming the thing that holds up your funding.
Why a flip needs different insurance than a rental
A standard homeowner or landlord policy is written for an occupied property in normal condition. It assumes someone is living there, the systems are working, and the building is not a construction site. A fix and flip breaks all three assumptions. The property is usually vacant, it is under active renovation with tools, materials, and open walls, and its condition is changing every week. Insurers price and underwrite around occupancy and condition, so a policy written for an occupied home often contains a vacancy exclusion that voids coverage once the house sits empty for thirty or sixty days, which is exactly the situation a flip creates.
That is where builder’s risk and vacant-property coverage come in. Builder’s risk insurance is written specifically for property under construction or renovation. It covers the structure and often the materials on site against fire, weather, theft, and vandalism during the rehab. Vacant-property coverage addresses the empty-house risk that standard policies exclude. Many investors carry a combined builder’s risk policy that handles both the vacancy and the construction exposure for the length of the project, which is what most lenders on a flip actually want to see.
What the lender requires and why
The lender’s interest in your insurance is direct: the property is its collateral, and the rehab money it is advancing is riding on that collateral surviving the renovation. So the lender requires coverage that protects the structure through the rehab, and it requires that the coverage name the lender as an additional insured or mortgagee, so that if the property burns down mid-project the insurance proceeds go toward protecting the loan rather than disappearing. This is the same logic that governs insurance on a pool of properties, which we cover in our guide to blanket loan insurance, applied to a single active project.
Lenders also care about the amount of coverage. On a flip the coverage generally needs to be enough to rebuild the structure, not the purchase price and not the after-repair value, but the cost to physically replace the building if it is destroyed. Underinsuring to save on premium is a false economy, because a partial loss on an underinsured property can leave you covering the gap out of pocket while the loan still expects the collateral restored. The insurance requirement usually sits right alongside the title and closing conditions, which we walk through in our guide to fix and flip loan title insurance and closing requirements.
What builder’s risk insurance costs
Builder’s risk on a flip is usually priced as a percentage of the coverage amount for the term of the project, and it is a real line item in your carry. As a rough frame, a builder’s risk policy commonly runs somewhere in the range of one to three percent of the structure’s insured value on an annualized basis, though the number moves with the property’s location, condition, the scope of the rehab, and how long the project runs. The heavier the construction and the longer the vacancy, the higher the rate.
Put numbers on it. Say you are rehabbing a house you bought for 140,000 dollars, the structure’s replacement cost is about 180,000 dollars, and a builder’s risk policy is quoted at roughly two percent of that insured value for a six-month project. That is about 3,600 dollars annualized, or somewhere around 1,800 dollars for the six months you actually hold it, depending on how the carrier prorates the term. On a flip projected to net thirty or forty thousand dollars, that eighteen-hundred-dollar premium is a small and necessary cost, but it is a cost, and it belongs in your holding-cost math from day one. We cover where it fits in our guide to fix and flip holding costs, and you can build the full carry into a deal on our DSCR deal calculator when you plan the exit into a rental. The premium also shows up alongside interest reserves as part of what a flip costs to carry while it produces no income, which we detail in our guide to interest reserves on fix and flip loans.
The coverage gap that catches investors
The most common and most expensive mistake is the gap that opens between policies. It happens like this. You buy the property, and either you carry over the seller’s homeowner policy or you take out a standard policy at closing to satisfy the lender quickly. The house sits vacant while you line up contractors. Somewhere around day thirty or sixty the vacancy exclusion in that standard policy quietly kicks in, and now you are renovating an uninsured property without realizing it. A loss during that window is not covered, and the first time you learn the exclusion existed is when the claim is denied.
The fix is to have the builder’s risk policy in force from the day you take title, not to bolt it on after the standard policy fails. If you are buying and immediately renovating, the property is a construction site from closing, so the construction policy should start at closing. If there is a real gap between acquisition and the start of work, you still need vacant-property coverage for that stretch, because an empty house is the exposure insurers price around most heavily. The cleanest approach is one policy that covers vacancy and construction for the full expected hold, with a little buffer past your target timeline in case the project runs long.
What happens when the project runs long
Flips run past their timeline constantly, and builder’s risk policies are written for a term. If your six-month policy expires and the rehab is not done, you have to extend or renew the coverage, and letting it lapse re-opens the exact gap that causes denied claims. Build the possibility of a long project into the coverage on the front end by matching or slightly exceeding your loan term, and put the renewal date on your calendar the same way you track your loan maturity. A project that runs long also affects your loan, and we cover that in our guide to fix and flip loan extensions, so keep the insurance and the loan term in sync.
The same discipline applies if you flip through an entity. The policy should be written in the name of the entity that holds title, and the lender named as mortgagee, so the coverage lines up with how the deal is actually structured. Investors who run flips through an LLC or another entity need the insurance, the title, and the loan all pointing at the same borrower, which we cover in our guide to fix and flip loans for LLCs and other entities. A policy in the wrong name is another quiet gap that surfaces at claim time.
The bottom line on builder’s risk and vacant-property insurance
A fix and flip does not need landlord insurance, it needs builder’s risk and vacant-property coverage, because the property is empty and under construction, and standard policies exclude both conditions. The lender requires the coverage, wants to be named as mortgagee, and wants enough insurance to rebuild the structure, and the premium, commonly a small percentage of insured value for the term, belongs in your holding-cost math from day one. The mistake that costs investors real money is the gap that opens when a standard policy’s vacancy exclusion kicks in mid-rehab, so put the right policy in force from the day you take title, match it to your loan term with a buffer, and renew it before it lapses if the project runs long. Handled correctly, insurance is a cheap and boring line item. Handled wrong, it is the reason a total loss becomes your loss.
