How Much Home Insurance Coverage Should a $400,000 House Have?
Base dwelling coverage on what it costs to rebuild the house, not its $400,000 price or purchase loan amount.

The $400,000 figure is the purchase price, which includes the lot, so it's not what dwelling coverage should be. Rebuilding cost depends on the house's square footage, materials and local construction rates, and often lands above or below the sale price. Some insurers run a replacement cost estimate during underwriting, or your agent can order one. Your lender will set a minimum, usually tied to the loan amount, but that's a floor, not the right number. Check the estimate against the actual house before closing, not the price you agreed to pay.
Rebuild cost, not purchase price, is what you're insuring
One quote might base dwelling coverage on an accurate rebuild estimate, another on your loan amount. Comparing quotes before closing shows which policy actually matches your house, not just your lender's minimum.
What about the other coverages besides dwelling?
Dwelling coverage sets the base, and the rest of the policy is usually built as a percentage of it. Personal property, which covers your furniture, clothes and belongings, is often set around half to seventy percent of the dwelling amount. Other structures, like a detached garage or a fence, is often around ten percent. Loss of use, which pays for a hotel and meals if the house becomes unlivable after a covered loss, is often around twenty percent. These are typical starting points an insurer offers, not fixed rules, and you can ask to raise any of them if the default seems low for what you own or where you'd need to stay.
Liability coverage is separate from all of this and doesn't scale off dwelling coverage at all. It pays for injuries or damage you're responsible for, like a guest hurt on your property, and legal costs if you're sued over it. A common starting point is $100,000, but many homeowners carry $300,000 or more, especially if you have savings or other assets a lawsuit could reach. This number is worth deciding on its own, not just accepting whatever the policy defaults to.
Your deductible, the amount you pay out of pocket before coverage kicks in, also shapes what you pay and what you'd owe after a claim. Some policies set this as a flat dollar amount, others as a percentage of dwelling coverage, which on a house insured for $400,000 could mean a deductible in the thousands rather than a few hundred dollars. A percentage deductible is worth checking for specifically, since it changes what a claim actually costs you in a way a flat number doesn't.
Once dwelling coverage is set correctly, these other numbers are what make the difference between two quotes that look similar on price. A lower premium sometimes comes from lower personal property limits or a higher deductible buried in the percentages, not from the insurer offering a better deal. Reading what each quote sets for personal property, liability and the deductible, not just the total cost, is how you see what you'd actually be covered for if something happened.
What does the lender actually need to see before closing?
The lender wants a binder, which is a temporary proof of coverage showing a policy is active as of closing day, before the final documents exist. It lists the dwelling coverage amount, the deductible and the lender's name as mortgage holder on the policy. Most agents can issue one within a day of binding coverage, but closings have been delayed waiting on this, so it's worth asking for it a few days ahead rather than the morning of.
Lenders also check that the dwelling amount meets their minimum, which is usually tied to the loan balance rather than the rebuild cost. If the rebuild estimate comes in above the loan amount, the lender's minimum is already satisfied, but it's not the number to stop at. If it comes in below the loan amount, which happens less often, the lender may require raising coverage to match their floor even if the house would cost less to rebuild. Either way, the loan amount and the rebuild cost are two separate checks, and passing one doesn't mean the other is right.
Once closing happens, the insurer bills the premium either directly or through escrow, an account the lender manages to collect property-related costs monthly along with the mortgage payment. Most lenders roll homeowners insurance into escrow automatically, meaning a twelfth of the annual premium is added to each mortgage payment rather than being paid as one lump sum at renewal. This is worth confirming before closing, since a few lenders allow paying the insurer directly instead, and the two paths show up differently on the monthly statement.
The policy also needs to be active on the exact closing date, not just purchased sometime before it. A gap between when the seller's coverage ends and the buyer's begins is the kind of detail a title company checks closely, so the effective date on the binder should match the closing date exactly rather than a day before or after.
Before you sign anything
Pull up the rebuild estimate and compare it against the dwelling amount on each quote, not the loan amount. Confirm the binder's effective date matches closing day exactly before anyone signs.
