What your lender needs before closing
Your lender will ask for proof of coverage, usually a document called a binder, showing a policy is in place before you own the house. That policy needs dwelling coverage equal to what it costs to rebuild the house, not what you paid for it or what it would sell for. The lender checks this number, and if it looks too low, they may ask you to raise it. You'll also pick a deductible, the amount you pay out of pocket before coverage kicks in. A higher deductible lowers what you pay for the policy. If you're escrowing, the yearly cost gets added to your mortgage payment and the lender pays the insurer directly from that account. Your closing agent will tell you the exact date the binder needs to be ready.
Dwelling coverage and deductible aren't fixed numbers tied to this house. Different insurers price the same rebuild cost differently, and the deductible you pick changes what you pay every year after. Since you're setting this policy up fresh, before any renewal history or habits lock you in, it's worth seeing what a few insurers quote for the same coverage before you tell your lender which one you're using.
What else a homeowners policy actually covers
Dwelling coverage is the part your lender cares about, but it's not the only part of the policy. Most policies also include coverage for your belongings, the things inside the house like furniture, clothes and electronics, usually set as a percentage of your dwelling coverage. There's liability coverage, which pays out if someone gets hurt on your property and sues you, or if you accidentally damage someone else's property. And there's loss of use, sometimes called additional living expenses, which pays for a hotel or rental if the house becomes unlivable after a covered loss while it's being repaired.
What counts as a covered loss depends on the policy, but most standard policies cover things like fire, windstorms, hail, lightning, theft and vandalism. They don't cover flood damage, that's a separate policy altogether, and in most states they don't cover earthquake damage either, which also needs its own policy or endorsement. If the house sits in a flood zone or an area with earthquake risk, the lender may require that coverage on top of the standard policy, and it's worth asking about before closing rather than finding out after.
Other structures on the property, like a detached garage, shed or fence, usually get their own smaller amount of coverage separate from the dwelling limit. This is often a percentage of the dwelling coverage automatically, but it's worth checking the declarations page once the policy is issued to see what number it actually lists. If there's anything unusual on the property, a pool, a workshop, an older structure, it's worth confirming it's accounted for rather than assuming it's covered.
All of this gets bundled into one policy with one price, but the pieces move independently. Raising dwelling coverage doesn't automatically raise liability coverage, and lowering the deductible affects the whole policy's cost, not just one part of it. When comparing quotes across insurers, it helps to look at all these numbers side by side, not just the price at the bottom, since two policies with the same price can cover very different amounts if one skimps on belongings or liability to make the dwelling number look competitive.
How insurers decide what it costs to rebuild your house
The dwelling coverage number your lender checks doesn't come from the purchase price or the appraisal you already got. Insurers calculate it separately. They use the square footage, the materials the house is built from, the age of the roof and systems, and local construction costs to estimate what it would take to rebuild the house from the ground up if it were a total loss. This is why two houses that sold for the same price can need very different amounts of dwelling coverage. A house with a slate roof and custom finishes costs more to rebuild than one with standard materials, even if they'd sell for the same number today.
The estimate usually comes from a questionnaire about the house, sometimes paired with a tool the insurer runs using public data. It can come in higher or lower than a buyer expects. If it comes in low, raising it before the policy is issued is straightforward. If it comes in high, it's worth asking what's driving the number, since an error in square footage or a misunderstanding about materials can inflate it. This number can be checked and adjusted before closing, and that matters. It's harder to catch a mistake once the policy is active and the binder is already in the lender's hands.
Most policies also include an option, sometimes built in, sometimes added for an extra cost, that covers the gap if rebuilding costs rise after a major disaster drives up demand for materials and labor. The dwelling coverage set at closing reflects rebuild costs on that date, not the cost five or ten years later, so this option matters more than it might seem to at first. Some policies adjust the dwelling number automatically each year, others require asking for a review. It's worth asking an insurer which approach they use before choosing a policy, not after filing a claim.
The details that shape this number are usually ones a buyer already has on hand. The inspection report and the seller's disclosures typically cover the roof's age, the type of siding, and whether the plumbing and wiring have been updated. Having those on hand before requesting quotes makes the dwelling coverage number accurate on the first try. That satisfies the lender's requirement. It also means the house is actually covered for what it would cost to rebuild, not just what it cost to buy.
Before you send the binder
Check the dwelling coverage number against your inspection report's square footage and roof age. A mismatch there is the easiest thing to fix now and the hardest to catch after the policy is active.
