Additional Named Insured vs Co-Insured on Home Insurance
Both are covered under the policy. An additional named insured can make changes to it. A co-insured usually cannot.

On a new policy, this comes down to who's listed and how. If you're buying the house with someone, ask the agent to add both of you as named insureds, not one as the policyholder and the other as a co-insured. That way either of you can file a claim, request changes or add coverage without the other's sign-off. Your lender only cares that dwelling coverage matches the loan amount and that its name appears correctly for escrow. The declarations page will show exactly who's listed and how, so check it before closing.
Policies vary in how easily they let a second owner handle a claim or make a change, and some insurers charge differently depending on how names are listed. Since you're setting this up for the first time, it's worth comparing how different carriers structure named insureds before you lock in a policy, rather than fixing it after closing when changes get harder.
Does it matter who's listed first on the policy?
Yes, in how the paperwork reads, though not in whether the house is covered. The person listed first is usually called the primary named insured. Insurers send renewal notices, cancellation letters and billing statements to that name. If you and a co-buyer are both named insureds, pick whoever will realistically handle the mail and the calls. That's mostly what the order affects. It won't change what's covered or whose signature is needed to file a claim.
Order can matter more once there's a claim check to be issued. Insurers typically write claim payments to all named insureds listed on the policy, and for a check tied to a mortgage, the lender's name gets added too. If one buyer is a named insured and the other is only a co-insured, the co-insured's name might not appear on that check at all. That can slow things down when both people need to sign off on repairs or deposits.
Married couples buying together are sometimes told it doesn't matter since they share finances anyway. It still matters for the policy itself. If only one spouse is the named insured and that spouse moves out, dies, or the couple separates before a claim, the remaining spouse may find they have no standing to file one or make changes, even though they live in the house and pay for it. Adding both as named insureds avoids that gap, and it costs nothing extra to ask for it.
Ask the agent directly how claims checks are issued when there's more than one named insured, and whether that differs from how a co-insured would be handled. The answer varies by carrier. It's a cleaner question to ask before the binder is issued than after a pipe bursts and three names need to agree on a contractor.
What about unmarried co-buyers or a cosigner who isn't living there?
Unmarried couples, friends buying together, and parents cosigning without moving in all run into this question. The instinct is to list the cosigner as a co-insured since they aren't living in the house, but that's usually backwards. If the cosigner's name is on the title or the mortgage, most insurers want them listed as a named insured too. Their financial interest in the house is the same as yours even if their address isn't.
A cosigner who isn't on the title is a different case. If they cosigned the loan but have no ownership stake, they don't need to be on the policy at all. What matters for the policy is who owns the house, not who's paying the mortgage. Check the title and the deed before deciding who goes where on the declarations page, since that's what the insurer is actually matching coverage against.
For unmarried co-buyers, the stakes are higher than for married ones. There's no shared last name or joint assumption that both of you are automatically covered the way a spouse might be. If one person is the named insured and the relationship ends, or that person moves out, the other co-buyer could be left with no way to file a claim or change coverage on a house they still partly own. Getting both names on as named insureds from the start avoids a mess that's much harder to untangle later, especially if the relationship is the reason you're trying to sort out who's covered in the first place.
Raise this with the agent by name, not as something that'll get handled correctly by default. Say plainly who's on the title and ask to have each of them listed as a named insured. It's a short conversation before closing. It's a much longer one if it only comes up after something happens to the house.
Before you sign anything
Check the declarations page for exactly who's listed and how. If you're buying with someone else, confirm both names appear as named insureds, not one as policyholder and the other as co-insured.
