Is It Illegal to Have a Mortgage Without Home Insurance?
No law requires it, but your mortgage lender does, and can buy costly coverage for you if you don't.

Why your lender is the one asking
No state makes you carry homeowners insurance. The requirement comes from your mortgage contract, where the lender makes it a condition of the loan, because the house is their collateral too. Before closing, your lender will want a binder, a short document showing coverage starts on the closing date, naming them as mortgagee. If you close without it, the loan doesn't fund. Once you own the house, let coverage lapse and the lender can buy a lender-placed policy on your behalf, add the cost to your mortgage payment, and charge you more for less coverage since it only protects their interest, not your belongings or your liability. Your loan documents say how much coverage they require, usually tied to the loan amount or the rebuild cost.
A lender-placed policy only exists to protect the loan balance. It skips your belongings, your liability if someone is hurt on the property, and often costs more than a policy you pick yourself would for real coverage on the house. Comparing options before closing, while you still control the choice, is how you get a binder that satisfies the lender and actually covers what you'd lose in a fire or storm.
How does escrow fit into paying for this
Most lenders fold your homeowners premium into an escrow account, which is just a holding fund attached to your mortgage. Instead of paying the insurer directly each year, you pay a monthly amount to the lender along with your mortgage payment, and the lender pays the insurer when the bill comes due. The same account usually covers property taxes too. At closing you will likely see a cushion of two or three months' worth of premium collected upfront, which is normal and not an extra fee someone is pocketing.
Your first year's premium is often paid in full at closing, either by you directly or through the escrow setup, and that payment is what makes the binder valid on the closing date. After that, the lender recalculates your escrow payment once a year based on the actual cost of your insurance and taxes. If your premium goes up at renewal, your monthly payment goes up too, sometimes by more than you'd expect, because the lender is adjusting for a full year of the new rate plus rebuilding the cushion.
Escrow does not mean the lender picked your insurer or that you are stuck with whatever policy they set up initially. You can shop and choose your own policy before closing, then give the lender the binder and declarations page so they know where to send the premium payment. If you switch insurers later, the same thing applies. You tell the lender, give them the new policy information, and the escrow payment adjusts to match.
One thing worth checking on your loan estimate or closing disclosure is whether escrow is required at all. Some loans, particularly those with a large enough down payment, let you waive escrow and pay your insurer directly. That gives you more control over timing and who gets paid, but it also means the full annual premium is your responsibility to track and pay on time, since a missed payment risks a lapse the lender will notice through the mortgagee clause on your policy.
What happens if your dwelling coverage doesn't match the rebuild cost
Your lender sets a minimum amount of dwelling coverage, usually tied to either the loan balance or the home's appraised value, but neither number is actually what it costs to rebuild the house. Rebuilding cost depends on local construction prices, the size and materials of the house, and what it takes to bring it up to current building code, not on what a buyer would pay for the lot and the house together. A $400,000 purchase price might sit on a house that would cost $280,000 to rebuild, or one that would cost $500,000, depending on the market.
If you insure to the loan amount because that's the number the lender gave you, and that number is lower than what rebuilding actually costs, you can end up underinsured. After a total loss, the payout is based on your dwelling coverage limit, not your mortgage balance or your home's market value. Come up short and you're covering the gap yourself, on a house that may no longer exist to live in while you do it.
Most insurers will estimate rebuild cost for you using the home's square footage, age, roofline, and finishes, and that figure is what should set your dwelling coverage, not the purchase price or the loan amount. It's worth asking directly how that number was calculated, since two houses that sell for the same price can cost very different amounts to rebuild depending on what's inside the walls. Setting coverage too low to save on premium is the most common way people end up underinsured without realizing it until a claim.
Once you have a dwelling coverage number that reflects actual rebuild cost, check that it still satisfies the lender's minimum. In most cases a correctly calculated rebuild cost comes in above the loan amount, so this resolves itself, but it's the dwelling figure, not the loan figure, that determines what you're actually protected for if the house is destroyed.
Before you lock in a quote
Check how your lender's minimum coverage was calculated against an actual rebuild cost estimate, not the loan amount or purchase price. If they don't match, that's the gap worth closing before closing day.
