What Is Home Insurance?
A policy that pays to rebuild your house and replace belongings if they're damaged, and covers injuries on your property.

Buying your first house and getting the policy in place
Your lender sets the deadline because it holds a stake in the house until the mortgage is paid off, and it won't close without proof of coverage, usually a binder showing the policy starts on closing day. The number that matters most is dwelling coverage, what it would cost to rebuild the house at today's material and labor prices, not what you're paying for it or what it would sell for. Your lender will want that figure high enough to cover the loan, but it should actually match rebuilding cost. Your deductible is what you pay out of pocket before coverage kicks in on a claim, and a higher one lowers your premium. Many lenders fold the annual premium into your monthly mortgage payment through escrow, paying the insurer directly once a year.
Rebuilding cost varies a lot between insurers even for the same house, because each one prices materials, labor and local construction differently. Two policies can list the same dwelling coverage number and still charge very different premiums for it, or quietly set that number too low to actually rebuild. Checking more than one quote before closing is how you find out whether you're paying a fair price for coverage that actually matches your house.
What does the policy actually pay for, beyond the house itself
Dwelling coverage pays to rebuild the house, but a policy is built from several coverages stacked together, and the declarations page lists each one with its own dollar limit. Other structures covers things not attached to the house itself, a detached garage, a fence, a shed. It's usually a percentage of your dwelling coverage, set automatically unless you ask to change it.
Personal property covers what's inside the house, furniture, clothes, electronics, if they're stolen or damaged by something the policy covers. It's typically a percentage of dwelling coverage too, and it's worth checking that the number is realistic for what you actually own rather than accepting the default. Some policies pay what it costs to replace an item new, others pay what the item was worth used, and that difference matters a lot if you ever file a claim.
Liability coverage is the part that pays if someone is injured on your property and sues you, or if you accidentally damage someone else's property. It's a separate limit from dwelling coverage, often overlooked by first-time buyers because it doesn't relate to the house's value at all, it relates to what you could be on the hook for. Loss of use, sometimes called additional living expenses, pays for a hotel and meals if the house is damaged badly enough that you can't live in it while it's repaired. A lender won't ask about any of these, since its interest is the structure that secures the loan, but they're the coverages that protect the buyer directly.
Flood and earthquake damage aren't included in a standard policy no matter how high the dwelling coverage is set. If the house is in a flood zone, the lender will likely require a separate flood policy, and that requirement shows up during the mortgage process rather than on the homeowners binder. Worth confirming before closing which risks the area actually carries, since adding coverage later is still possible but costs more to arrange in a hurry than to plan for upfront.
What else shows up on the declarations page
Once dwelling, other structures, personal property, liability, and loss of use are set, a few more lines on the declarations page decide how a claim actually plays out. One is the deductible structure itself. Most policies carry a flat dollar deductible, something like a thousand or two thousand dollars, but in areas prone to wind or hail some insurers set a percentage deductible instead, a share of the dwelling coverage rather than a fixed number. On a house insured for three hundred thousand dollars, a two percent deductible comes out to six thousand dollars out of pocket before coverage starts. That's a very different number than a flat one thousand, and it's easy to miss if you're only comparing premiums.
Named perils versus open perils is another distinction worth understanding before signing anything. A named peril policy pays only for the specific risks it lists, fire, lightning, wind, and so on. An open peril policy, sometimes sold as a broader HO-3 or HO-5 form, covers any cause of damage except what it specifically excludes. Most standard policies written for a primary residence are open peril on the dwelling and named peril on personal property, which means the house itself is covered more broadly than what's inside it. The declarations page won't always spell this out in plain language, so it's worth asking directly which form applies.
Endorsements, sometimes called riders, are add-ons that extend coverage beyond what the base policy includes. Jewelry, musical instruments, and fine art often carry limits far below their actual value under personal property coverage, so a separate endorsement with its own appraisal may be needed to insure them properly. Water backup from a sewer or sump pump is excluded by default in most policies and has to be added on. None of these show up as a requirement from the lender, since they fall outside what secures the loan, but they're often the difference between a claim that's fully paid and one that leaves a gap.
Replacement cost versus actual cash value is worth checking on the whole policy, not just personal property. Replacement cost pays what it takes to rebuild or replace at today's prices. Actual cash value subtracts depreciation first, so a ten-year-old roof might only be paid out at a fraction of what a new one costs. Some insurers write the dwelling on a replacement cost basis but default personal property to actual cash value, and the only way to know which applies is to read that section of the policy or ask directly before the binder is issued.
Before you sign the binder
Pull up the declarations page before closing. Compare the dwelling coverage number to what it would actually cost to rebuild the house, check the deductible amount, and see whether personal property pays replacement cost or actual cash value.
