What Is Escrow on a House?
An account your lender holds to pay property taxes and insurance for you, using monthly payments built into your mortgage.

Before closing, your lender needs proof your policy is active, usually a document called a binder or a declarations page. Once you close, your first year's premium is often collected upfront and paid through that escrow account, not billed to you directly. Each year after, your insurer sends the renewal cost to the lender, who adjusts your monthly escrow payment to cover it. This is why your mortgage payment can shift even when your rate doesn't. Your premium changed, and escrow is paying for it on your behalf.

Once your escrow account starts paying the renewal, that cost rolls into your mortgage payment automatically. Checking your options now, before closing, means the premium built into your escrow is one you chose, not just the one you were handed.
What happens if your escrow payment is wrong
Escrow accounts are reviewed once a year, usually around your mortgage anniversary, in a process called an escrow analysis. Your lender adds up what it paid out for taxes and insurance over the past year and compares that to what it collected from you each month. Then it adjusts your payment going forward. If your insurance premium went up at renewal, or your property taxes increased, your monthly payment goes up too, sometimes by more than you expected.
Lenders are required to keep a cushion in your escrow account, but they can't let it run short. If the account dips below what's needed, you'll see a shortage on your escrow analysis statement. You usually get a choice. Pay the shortage in one lump sum, or let the lender spread it across your next twelve monthly payments. Either way, it gets paid. The analysis statement shows you the math, so it's worth reading rather than filing away.
The reverse happens too. If your insurer's renewal came in lower than expected, or you switched to a cheaper policy mid-year, your escrow account can end up with a surplus. Depending on the amount and your state's rules, the lender may refund the difference to you directly or apply it to next year's payments. This is one reason it's worth knowing what your policy actually costs. A change you make to your coverage shows up in your mortgage payment, not a separate bill.
None of this changes what your policy covers. Escrow is just the mechanism that moves money from you to your insurer through your lender. If you cancel a policy or switch insurers, you're responsible for making sure the lender has proof of the new policy before the old one lapses. A gap in coverage on an escrowed loan can prompt the lender to buy its own policy on your behalf, usually at a much higher cost than anything you'd choose yourself.
What proof do you need before closing, and when
Your lender will ask for a binder before closing, not a full policy. A binder is a short document from the insurer stating that coverage will be active as of a specific date, usually the closing date. It names the property, the coverage amount, and the insurer, but it isn't the full policy packet with all the fine print. That comes later, often by mail or email, once the policy is actually issued.
The lender usually wants this a few days before closing, not the morning of. Title companies and lenders coordinate the closing date with the insurance start date, so the binder's effective date needs to match. If you bind coverage too early, you could end up paying for a policy on a house you don't own yet. Too late, and closing can get delayed while the lender waits on paperwork. Ask your lender exactly when they need the binder in hand, since this varies by lender and by state.
The dwelling coverage amount on your binder matters more than most buyers realize at this stage. Lenders typically require dwelling coverage at least equal to the loan amount, but that's a lending minimum, not necessarily what it would cost to rebuild your house. Those two numbers aren't the same thing. If your home would cost more to rebuild than your loan balance, and many would, buying coverage only up to the loan amount can leave you underinsured even though it satisfies the lender. Your insurer can help estimate rebuilding cost based on the home's size, materials, and local construction prices.
Once the policy is active, keep a copy of the declarations page somewhere easy to find. It lists your coverage amounts, your deductible, and the policy period, and you'll want it on hand anytime the lender's escrow analysis doesn't match what you expect, or if you're comparing policies at renewal. If anything changes between binding coverage and closing, a change in coverage amount, a different insurer, a new deductible, let your lender know right away so the paperwork on file matches the policy that's actually in force.
Before you lock in a number
Check your binder's dwelling coverage against what it would actually cost to rebuild the house, not the loan amount or the sale price. That's the figure escrow will be paying for every year.
