Homeowners Insurance and Escrow
Escrow is a lender account that collects part of your premium monthly and pays the insurer when it's due each year.

How your premium gets paid once escrow is set up
Before closing, the lender wants a binder, which is proof you've bought the policy, and the full first year's premium is usually due then, either from you directly or through the closing costs. After that, the lender opens an escrow account and divides your annual premium into monthly pieces, added to your mortgage payment along with property tax. Each year, when your policy renews, the insurer bills the lender directly, and the lender pays it from what's built up in escrow. If your premium goes up at renewal, your monthly escrow payment goes up too, since the lender has to collect more to cover the new bill. Your mortgage statement will show the escrow balance and the breakdown between insurance and tax, so you can see what's being collected and why.
The premium you pick now sets your escrow for the year
Whatever premium you lock in before closing becomes the number your lender divides into monthly escrow payments. A policy that costs less to start keeps that monthly piece smaller, not just the upfront bill.
What happens if your escrow account runs short or has extra
Once a year, the lender reviews your escrow account in what's called an escrow analysis. It looks at what came in, what went out for insurance and property tax, and whether the account kept the cushion it's required to hold. If your insurance premium or tax bill went up during the year and the lender didn't collect enough to cover it, the account runs short. You'll get a notice showing the shortage. You usually have two options, pay the difference in one lump sum, or let the lender spread it across the next year's payments, which raises your monthly mortgage payment until it's made up.
The opposite can happen too. If your premium came in lower than expected, or the lender collected more than it needed, you end up with a surplus. Depending on the amount and your lender's policy, you might get a refund check or see your monthly payment adjusted down. Either way, the yearly analysis is when these differences get caught and corrected, not spread out quietly over time.
A policy that renews at a much higher rate creates a bigger shortage for the lender to collect later, on top of whatever the new premium costs. Shopping again before each renewal, rather than letting the policy auto-renew untouched, is one way to keep that yearly escrow adjustment from catching you off guard. The premium chosen before closing sets the pattern, but it isn't the only number that matters once renewals start arriving.
If coverage changes, like raising the dwelling coverage limit or adding an endorsement for something the policy excludes, the lender needs to know once the change is made. Escrow is built around whatever premium the insurer bills, so a change that isn't reflected yet can throw off the next analysis. The declarations page shows the current premium and what it covers, and that figure should match what the lender has on file.

What if you change insurers or coverage after closing
Nothing locks you into the policy you bought before closing. If a renewal comes in high, or another insurer offers the same dwelling coverage for less, switching is allowed and doesn't require the lender's approval first. What matters is that the lender ends up with the right information once the switch happens.
When you buy a new policy, the new insurer issues a declarations page showing the dwelling coverage, the deductible and the premium. That needs to go to the lender, usually through whoever services the mortgage, so escrow gets billed correctly going forward. If the old policy is canceled before the lender is told about the new one, there can be a gap where the lender thinks there's no coverage at all. Some lenders respond to that by buying force-placed insurance on your behalf, which costs more than almost anything available on the open market and gets added straight to the mortgage payment. Lining up the new policy's start date with the old one's cancellation date avoids that.
Switching mid-year also means a new premium figure for the lender to work with, and it won't match what was collected in escrow so far under the old policy. This usually sorts itself out at the next escrow analysis, but if the new premium is significantly lower, letting the lender know sooner can mean a smaller monthly payment sooner, rather than waiting a full year for the adjustment. If it's higher, the same applies in reverse, and getting ahead of it avoids a shortage notice later.
Raising or lowering coverage works the same way. Increasing dwelling coverage to match rebuilding costs, or adding an endorsement for something the standard policy excludes, changes the premium the insurer bills. That new figure needs to reach the lender the same way a new policy would. Escrow only works with the numbers it's given, so keeping the declarations page, the insurer and the lender's file in agreement is what keeps the monthly payment accurate instead of catching up all at once.

Before you lock in a policy
Check your declarations page against what the lender has on file, now and after any change. Matching numbers keep escrow accurate instead of catching up later with a shortage notice.
