How Often Do Lenders Do Escrow Analysis?
Once a year, usually. Lenders review escrow annually to check your insurance and tax costs match what you're paying in.

Why this matters before you've even closed
The escrow review itself is a future event, but the account starts the day you close, and what goes into it depends on the insurance policy you buy now. Your lender collects a portion of your annual premium each month along with your mortgage payment, holds it, and pays your insurer when the bill comes due. If you buy a policy with a low premium now and your dwelling coverage turns out to be too low to actually rebuild the house, you'll likely face a jump at the next annual review, either from a rate increase or from having to raise coverage. Picking a policy that matches what the house would actually cost to rebuild, not just what satisfies the lender's minimum, keeps that first review from being a surprise.
The premium set now is what your escrow account is built around for the next year, so the policy worth choosing is one priced to actually rebuild the house, not the cheapest one that clears closing. Comparing quotes before you commit shows where dwelling coverage and price actually line up, so the policy funding escrow is one that holds steady at the first review instead of forcing a correction.
What happens if the escrow analysis finds a shortage
When the annual review turns up a gap between what's in the account and what was actually paid out, the lender covers the shortage first and then fixes the monthly payment so it doesn't happen again. You'll get a notice showing the math. It lists what was collected, what went out for insurance and taxes, and the difference between them. That difference gets added to your new monthly payment, spread over the next 12 months, or you can usually pay it in one lump sum if you'd rather not raise your monthly bill.
A shortage after the first year is common even when nothing went wrong. Property taxes get reassessed. Insurance premiums go up at your own renewal, separate from the escrow review itself. Neither of those is a sign you picked the wrong policy. What you can control going in is the size of the gap. A policy bought to satisfy the lowest number your lender would accept tends to need a bigger correction later than one priced closer to what coverage actually costs to maintain.
The reverse happens too. If the account collected more than it needed, usually because your insurance or tax bill came in lower than estimated, the lender either cuts your next payment or sends you the surplus directly, depending on the amount and your state's rules. This is routine and doesn't mean anyone overcharged you. It just means the estimate used when escrow was set up didn't match the actual bill.
None of this is predictable to the dollar before you've closed, since taxes and premiums are both partly out of your hands once the policy is in place. What is in your hands right now is the premium itself. A policy that's priced honestly against the cost to rebuild the house gives the lender a more accurate number to build escrow around from the start, and that means less chance of a steep correction showing up in that first annual letter.
What changes your escrow payment between reviews
Your monthly payment isn't locked in for the year just because escrow was set up at closing. Two things can change it before the next scheduled analysis even happens. One is you switching insurers mid-year, which resets what the lender is paying out. The other is a tax bill coming in in a different amount than what was estimated at closing, which the lender usually can't do much about until the next review catches it.
Switching insurers is the one buyers have some say over. If you shopped quickly to make a closing deadline and want to compare options again once you're settled in, you can do that, and the new premium gets reported to the lender so escrow reflects the new number. This doesn't trigger an early full review of your account, but it does change what the lender is collecting each month going forward, usually adjusted at the next natural reset point rather than instantly.
Some states also require lenders to pay interest on escrow balances, and a few require an annual statement showing that interest separately from the shortage or surplus notice. Whether this applies depends on where the house is, and it has nothing to do with the policy picked. It's worth knowing about only so the statement doesn't look unfamiliar when it arrives.
What ties all of this back to the policy chosen at closing is simple. An escrow account is just a pass-through for whatever the insurance and tax bills actually are. It doesn't create cost or absorb it. A policy bought to actually cover rebuilding the house, priced honestly rather than to hit the lowest number a lender will accept, is the one piece of the escrow math that's set before closing and stays steady unless a reader chooses to change it.
Before you close
Check that the dwelling coverage on the policy matches what it would cost to rebuild the house, not the purchase price. That number is what escrow is built on for the first year.
