Tenants in Common vs Joint Tenants: Home Insurance Impact
Ownership type doesn't change your policy. All owners can be named as insureds either way, so coverage works the same.

Why your lender still cares how you hold title
The way you and a co-owner hold title decides who inherits the house, not who the insurer pays. For the policy, what matters is that every person with a financial stake in the house is listed as a named insured on the declarations page. If you're buying with a partner, a parent or a friend, whether you're tenants in common or joint tenants, tell the insurer both names before the binder is issued. Leaving one owner off can cause problems later if that person needs to file a claim or if the lender checks the policy against the title. Your lender will compare the names on the deed to the names on the insurance binder, so matching them up before closing avoids a delay.
Getting the named insureds right before closing is worth checking now, since a mismatch between the deed and the binder is one of the more common reasons lenders send a policy back for correction. Comparing quotes side by side lets you confirm each insurer handles multiple owners the way yours needs, while also seeing what dwelling coverage and deductible actually fit the house you're buying.
What happens to the policy if one owner leaves or passes away
Tenants in common and joint tenants differ most in what happens after one owner is gone, and that difference reaches the insurance policy even though the insurer didn't cause it. With joint tenants, the surviving owner typically takes full ownership automatically. With tenants in common, the departing owner's share passes to whoever they named, which might not be the co-owner at all. Either way, the policy needs updating once title changes, since the declarations page should reflect who actually owns the house now.
If a co-owner dies and their share passes to someone outside the household, through a will under a tenants in common arrangement, that new owner may need to be added as a named insured or the policy may need to be rewritten entirely. An insurer paying out a claim wants the names on the policy to match who has a legal interest in the house at the time of loss. A gap here doesn't usually surface until there's a claim, which is the worst time to find out the paperwork is behind.
The same issue comes up with divorce or a falling out between co-owners, which is more a tenants in common situation since joint tenants usually buy with the expectation of staying joint. If one owner moves out but remains on the deed, they likely still need to stay on the policy too, since removing a named insured who still has a financial stake can leave their share of the house uninsured if something happens. The reverse causes problems as well. Taking someone off the deed without telling the insurer means the policy may still list someone with no ownership stake, which can raise questions when a claim is filed.
None of this needs solving before closing. What's worth doing now is asking how each insurer handles adding or removing a named insured later, since some make it a quick call and others want a new application. For a shared purchase, especially one between people who aren't married, knowing that answer up front saves a scramble if the ownership changes down the road.
What if the co-owners aren't a couple, like siblings or friends
Buying a house with a sibling, a friend, or a parent raises questions a married couple buying together usually doesn't, and insurers see this arrangement often enough to have an answer. The policy itself doesn't ask why the owners are grouped the way they are. It only asks who has a financial stake in the house, and it treats a group of friends holding title as tenants in common the same way it treats siblings or a couple. The named insureds go on the declarations page regardless of the relationship between them.
Where the relationship matters is in how a claim gets paid out and how decisions about the policy get made. If the house is damaged and a claim is filed, the insurer typically cuts one check made out to all named insureds, which means the owners need to agree on what happens to that money, whether it goes toward repairs or gets split. This isn't an insurance rule so much as a practical reality of shared ownership, but it's worth sorting out between the co-owners before a claim happens rather than during one.
Unmarried co-owners also run into a question married couples rarely face, which is what happens if one person wants out while the other wants to keep the house. Since tenants in common can sell or will their share independently, one owner moving out and selling their stake to someone new means a new named insured joining the policy, possibly someone the insurer and the remaining owner have never dealt with before. Checking now how the insurer handles that kind of change, whether it requires a new application or just a phone call, is a reasonable thing to ask before closing even if nobody plans to sell anytime soon.
None of this changes what coverage costs or what the dwelling coverage needs to be. It affects paperwork, not price. For co-owners who aren't married, it's worth having a short conversation about how the insurance side of a shared purchase works alongside the legal side, since a lender cares about the binder matching the deed today, but the owners are the ones who'll deal with the policy for as long as they own the house together.
Before you request a binder
Check the deed for every name on it, then make sure the same names go on the declarations page as named insureds. That match is what your lender checks before closing.
