What Are the Differences Between HO-1, HO-2, and HO-3?
HO-1 covers only named perils, HO-2 covers more, and HO-3 covers your house for all risks except what's excluded.

Which one your lender will actually accept
Your lender sets the floor here, and almost every lender requires an HO-3 or better, not the bare-bones HO-1. HO-1 policies are rare now because they only pay out for perils spelled out by name, like fire or lightning. Anything not listed is not covered. HO-2 adds more named perils but still works the same way. If it's not on the list, you're on your own. HO-3 flips that. Your house is covered for any cause of loss except the ones your policy specifically excludes, which usually includes flood and earthquake. For closing, ask the lender what tier they require, then check the quote's declarations page to confirm it says HO-3. Your belongings inside the house are often still covered on a named-peril basis even under an HO-3, so that part is worth a separate look.
Two HO-3 quotes can still land far apart in price, and the gap usually comes from the dwelling coverage amount and the deductible, not anything about the policy tier. One insurer might base your dwelling coverage on what it actually costs to rebuild the house. Another might quote lower by underestimating that number. Comparing quotes before closing is how you catch that difference while you still have time to fix it.
What HO-3 actually leaves out
An HO-3 covers your house for any cause of loss except what the policy names as excluded, so the exclusions list matters more than anything else on the declarations page. Flood is excluded on every standard homeowners policy, no matter the tier. If the house sits anywhere near a floodplain, the lender may require a separate flood policy through the National Flood Insurance Program or a private carrier, and that gets arranged separately from the HO-3.
Earthquake is usually excluded too, and in most states it's an endorsement you add to the same policy rather than a policy you buy elsewhere. Whether you need it depends on where the house is. A few other exclusions show up on nearly every HO-3 regardless of state. Sewer backup is one, and it has to be added back as its own endorsement. Mold is covered only up to a small payout. Damage from neglect or a lack of maintenance is not covered, and neither is ordinary wear and tear, since insurance pays for sudden loss, not for things breaking down over time.
Dwelling coverage is the number tied to most of this, and it's worth understanding before you sign anything. It's what it would cost to rebuild the house at today's labor and material prices, not what you're paying to buy it and not what the county says it's worth for tax purposes. Those three numbers are often close, but they come from different calculations, and a policy built on the wrong one can leave the rebuild underfunded after a total loss. The quote should show how that figure was reached, whether from a contractor estimate, a builder's calculator, or the sale price with a markup applied.
The deductible is the other piece worth reading closely before closing. Standard policies list one deductible for most claims, but many states allow or require a separate, usually higher, deductible for wind or hurricane damage. That one is often written as a percentage of the dwelling coverage rather than a flat dollar figure. If the quote has a wind or hail deductible, it is worth working out in dollars what that percentage actually means. It can run into thousands more than the standard deductible for everything else.
What else is worth checking before closing
Personal liability coverage sits on every HO-3 alongside the dwelling coverage, and it is easy to skip past since it is not what the lender is asking about. It pays out if someone is hurt on the property and sues, or if you are responsible for damage to someone else's property. Most policies default to a standard amount, often lower than what a homeowner with any savings or equity would want. Raising it costs little compared to the dwelling coverage, and it is worth asking the quote to show what the increase would run.
Loss of use coverage is the piece that matters if the house becomes unlivable after a covered loss, say a fire or a burst pipe that floods the main floor. It pays for a hotel or rental while repairs happen, plus the difference in cost for things like meals out. It is usually set as a percentage of the dwelling coverage, so a policy with dwelling coverage set too low on purpose will also come with less help here, and that is another reason the rebuild figure matters beyond just the structure itself.
Scheduling personal property is worth a look for anyone bringing in jewelry, art, musical instruments, or similar items into the new house. The standard personal property coverage on an HO-3 caps what it pays for categories like these, sometimes at a figure far below what the items are worth. Scheduling an item means listing it separately with its own coverage amount, usually after an appraisal, and it costs more but removes the cap. This has nothing to do with the house itself, but it is the kind of thing that gets missed when the whole process is centered on satisfying the lender.
Finally, the binder the lender wants by closing is not the full policy, just proof that coverage will take effect on the closing date. It is worth confirming with whoever is issuing it that the dwelling coverage, deductible, and effective date on the binder match what was actually quoted and agreed to. Binders are sometimes generated early in the process and not updated if numbers change afterward, and a mismatch discovered at the closing table is a bad place to find one.
Before you sign anything
Pull up the declarations page from the quote. Check that it lists HO-3, shows the dwelling coverage figure you agreed to, and spells out the deductible. Then confirm the binder matches all three before closing day.
