Mortgage Escrow Account Seattle: Why Your Payment Changed in Year Two

A mortgage escrow account Seattle homeowners pay into every month is a holding account your servicer uses to pay your property taxes and homeowners insurance when they come due. Your principal and interest do not change on a fixed-rate loan. The escrow portion is re-estimated once a year, and in King County the first re-estimate after a purchase is frequently larger than the one built at closing. That is the whole story behind most "why did my payment go up" calls, and it is fixable once you understand the two moving parts.

I get this call most often about twelve to fifteen months after closing, usually from a first-time buyer in Wallingford or Capitol Hill who did everything right and is now looking at a servicer letter that reads like a bill for something they never agreed to. Nobody did anything wrong. The escrow account was set up on the information available at closing, and the information changed.

What follows is how the account is funded, why the first-year estimate drifts, how King County's assessment cycle interacts with a sale, what a shortage is and how you cure it, and when waiving escrows is even an option. I have checked the federal rule and the county's published cycle rather than writing from memory, because the specifics are what make the letter make sense.

What a Mortgage Escrow Account Seattle Homeowners Pay Into Actually Does

Every month you send your servicer one payment. The servicer splits it. Principal and interest go to the loan. The rest goes into the escrow account, where it sits until the King County Treasury bill and your insurance premium are due. When those bills arrive, the servicer pays them from the account on your behalf.

A mortgage escrow account Seattle servicers administer is not an extra fee, and the servicer does not keep the money. It is your money, held in trust, disbursed for bills you would otherwise pay in lump sums. The reason lenders want it is simple: an unpaid tax bill in Washington becomes a lien that sits ahead of the mortgage, and a lapsed insurance policy leaves the collateral unprotected. Escrow removes both risks by making the payments automatic.

What goes into the account on a typical Seattle purchase:

• King County property taxes, paid in two halves, due April 30 and October 31.
• Homeowners insurance premium, paid annually to your carrier.
• Flood insurance where the property requires it, which in central Seattle is uncommon but not unheard of near the lake and ship canal.
• Mortgage insurance on a conventional loan with less than 20 percent down, which Fannie Mae requires to be escrowed and which cannot be waived while it is in force. My guide to removing PMI in Seattle covers how that line item eventually comes off, and I mention it here because escrow and PMI removal are the two things new homeowners most often confuse with each other.

HOA dues are not escrowed. If you bought a condo or a townhome in condo form, you pay the association directly, which is one more reason to read my piece on Seattle townhome financing before you assume a fee-simple townhome has no association at all.

How a Mortgage Escrow Account Seattle Buyers Open Is Funded at Closing

Your Closing Disclosure has a section labeled "Initial Escrow Payment at Closing." That deposit, plus the monthly escrow portion of your payment, is what the servicer uses to build the account. It is calculated to do three things.

First, cover the bills that come due before your monthly deposits catch up. If you close in March and the first-half tax bill is due April 30, there is not enough time to collect it a twelfth at a time, so the closing deposit covers the gap. This is why the initial escrow deposit is much larger on some closings than others, and it has nothing to do with your loan quality. It is a calendar question.

Second, hold a cushion. Federal rule allows a servicer to keep a reserve in the account to absorb small increases. Under Regulation X, the rule that implements the Real Estate Settlement Procedures Act, that cushion is capped at one-sixth of the estimated total annual disbursements from the account, which works out to about two months of escrow payments. A servicer may hold less. It may not hold more, unless your loan documents or state law set a lower ceiling.

Third, produce an initial escrow account statement. The servicer must give you one at settlement or within 45 calendar days of settlement. It lays out the anticipated disbursements month by month for the coming year and the balance the account is expected to carry. Keep it. When the first annual analysis arrives, that statement is what you compare it to.

The number every one of those calculations depends on is the estimated annual property tax. And that estimate is where a Seattle purchase goes sideways.

Why the Year-One Estimate Is Usually Wrong on a Seattle Purchase

At closing, the only tax figure anyone has is the seller's current bill. The mortgage escrow account Seattle buyers close with gets built on that number. It is a reasonable starting point and it is frequently the wrong number for you, for two separate reasons.

The assessment cycle runs a year behind the bill

King County's Board of Appeals and Equalization states it directly: "The assessment year is the year before the tax is due. For example, a 2019 assessment determines taxes payable in 2020." Washington counties value property as of January 1 of the assessment year, and the county mails valuation change notices "each year between May and November of the assessment year." So the bill you pay in your first year of ownership reflects a valuation set before you ever saw the house, and the bill after that reflects a valuation set while you were moving in.

Central Seattle values have risen more years than they have fallen, and the tax bill follows the valuation with a lag. Two consecutive bills built on two consecutive assessments can differ meaningfully even when nothing about the house changed.

The seller's bill may not resemble yours

King County revalues every year at market, and a recent arm's-length sale is exactly the kind of evidence the assessor's models consume. A closed sale does not mechanically reset the assessed value to the contract price the way some states handle it, and I want to be careful not to overstate the mechanism. What I can say from twenty years of watching Seattle closings is that a purchase price well above the prior assessed value tends to be followed by a valuation that closes the gap, and that the escrow account built at closing did not anticipate it.

There is a second version of the same problem that has nothing to do with the assessor. A seller who qualified for the state senior or disabled property tax exemption was paying a reduced bill. That exemption does not transfer with the deed. A buyer who does not qualify inherits the full levy, and if the escrow account was built on the exempt bill, the first analysis will show a shortage that is large and entirely predictable. Ask the listing agent whether any exemption is on the parcel before you write. It changes your real monthly cost.

Insurance adds a smaller version of the same drift. Your first-year premium was quoted for a house the carrier had never insured. Renewal pricing in the Pacific Northwest has been moving, and the renewal is what the second-year escrow gets built on.

The Annual Escrow Analysis and the Shortage That Comes Out of It

Once a year, at the end of what the rule calls the escrow account computation year, the servicer re-runs the numbers. It totals what it actually paid out, projects what it expects to pay next year based on the most recent tax bill and insurance premium, and compares the balance in the account to the balance it needs. Regulation X requires the servicer to send you the resulting annual escrow account statement within 30 days of the end of the computation year.

Three outcomes are possible.

• Surplus. The account holds more than it needs. If the surplus is 50 dollars or more, the servicer must refund it to you within 30 days, provided the loan is current. Under 50 dollars, the servicer may refund it or credit it against next year's payments.
• Shortage. The account is on track to hold less than it needs once the cushion is included. This is the common outcome after a Seattle purchase, for the reasons above.
• Deficiency. The account actually went negative, meaning the servicer advanced its own money to pay a bill. This is rarer and is usually the result of a tax bill that jumped sharply mid-year.

The new monthly payment on the statement has two components stacked on top of each other, and separating them is the key to reading the letter. One component is the higher ongoing escrow deposit, because next year's bills are estimated higher. The other is the shortage repayment, which is temporary. Once the shortage is repaid, that piece drops off, but the higher ongoing deposit stays.

Mortgage Escrow Account Seattle Shortage: Pay It in a Lump Sum or Spread It

Regulation X sets the floor on how a servicer may collect a shortage, and the floor depends on the size of the shortage relative to one month's escrow payment.

Nearly every mortgage escrow account Seattle servicer letter offers you both paths: pay the shortage in full now and your payment rises only by the ongoing increase, or do nothing and the shortage is spread over the coming year on top of the ongoing increase. Neither path carries interest. The shortage is simply your money that the account needs.

Illustrative example, general in nature and current as of September 2026. Suppose your escrow analysis shows the ongoing monthly escrow deposit needs to rise by 120 dollars, and there is a shortage of 1,440 dollars. Spread over 12 months, the shortage adds another 120 dollars a month, so your payment rises by 240 dollars for a year and then drops back to a 120-dollar increase. Pay the 1,440 dollars now and the payment rises by 120 dollars from the start. Same total money either way. The question is only whether you would rather hold the cash or hold the smoother payment. Figures are illustrative only and not a quote.

My general advice: if the lump sum comes out of an emergency fund you would then have to rebuild, spread it. If it comes out of cash that was sitting idle, pay it and keep the monthly obligation lower. What I would not do is ignore the letter, because the higher payment starts on the date the statement names whether you respond or not, and an autopay set at the old amount will come up short.

If the new tax figure itself looks wrong, that is a different conversation. Valuation notices in King County carry an appeal window, and the county publishes that petitions must be filed by July 1 of the assessment year or within 60 days of the date on the value change notice. Appealing an assessment is a county process, not a servicer one, and the outcome flows into a later escrow analysis rather than the current one.

Waiving the Mortgage Escrow Account Seattle Lenders Set Up

Sometimes, and the answer depends on the loan more than the borrower.

Conventional loans. Fannie Mae generally requires escrow for taxes and insurance on first mortgages, but allows a lender to waive it for an individual loan under the lender's own policy, as long as the standard escrow provision stays in the loan documents so it can be reinstated. The guide is specific that the waiver decision cannot rest on the loan-to-value ratio alone. The lender has to consider whether you have the financial ability to handle the lump-sum tax and insurance payments yourself. Two things cannot be waived on a conventional loan: borrower-paid mortgage insurance, which must be escrowed while it is in force, and certain refinances where property taxes were financed into the loan amount.

Higher-priced mortgage loans. If your loan's rate lands far enough above the average prime offer rate to be classified as a higher-priced mortgage loan under Regulation Z, an escrow account is mandatory for a minimum of five years after closing. After five years, you may request cancellation, but only if the unpaid principal balance is below 80 percent of the original property value and you are not delinquent or in default. This classification is rare on the well-qualified central-Seattle files I typically see, but it exists and it overrides lender discretion.

FHA and VA. FHA loans carry an escrow account as a program requirement. Waiving is not on the table. For VA borrowers, escrow is the standard lender practice and waivers are uncommon. Program requirements vary by lender and investor and are subject to change.

Pricing. Many investors charge a small loan-level price adjustment for an escrow waiver, because a loan without escrow carries more risk to them. Ask what the waiver costs before you assume it is free. I do not quote pricing on this site and the adjustment varies by investor and by the file.

Should you waive it, if you can?

The honest case for waiving is that you would rather hold your own money until the bill is due, which on a large Seattle tax bill is real money sitting in your account for months. The honest case against it is that two semi-annual tax payments and an annual insurance premium are large, irregular, and easy to be surprised by, and that the county does not send reminders in a way that fits everyone's attention. Most of the first-time buyers I work with are better served by the account for the first few years. Most of the borrowers who ask me for a waiver are on their third or fourth home and already run their finances on a calendar. Both groups are right for their situation.

An escrow waiver is also available to a borrower who is refinancing, which is one of the smaller reasons people pursue a refinance in Seattle even when the rate math is neutral. It is rarely a reason on its own.

What I Tell Buyers Before Closing So the Year-Two Letter Is Not a Surprise

Almost all of this is avoidable with a few questions asked before the mortgage escrow account Seattle closing builds is ever funded. My sequence, in the order I run it:

1. Estimate the tax bill on your price, not the seller's bill. During pre-approval I run the payment on a tax figure that reflects the current King County levy rate applied to something close to what you are paying, so the qualifying number is conservative.
2. Ask whether any exemption is on the parcel. A senior, disabled, or other exemption held by the seller does not transfer with the deed, and the full bill is yours from the first cycle you own.
3. Read the initial escrow account statement at closing. It is part of the closing costs package and it tells you exactly what tax figure the account was built on. If it is obviously the seller's reduced bill, ask escrow to re-run it on a higher figure. A larger initial deposit at closing is a much smaller shock than a shortage letter a year later.
4. Check the valuation notice when it arrives. King County mails them between May and November. That notice tells you what next year's bill will be built on, months before the escrow analysis catches up to it.
5. Update autopay the month the new payment starts. The statement names the effective date. Set the new amount before it.

Done in that order, the year-two letter is a confirmation of a number you already knew. Done in no order at all, it is a call to me at 7 a.m. from a client who is convinced the rate changed.

For neighborhood context on the homes and price points where this matters most, my Wallingford home loan guide and Capitol Hill guide cover the markets where first-time buyers most often close on a house with a tax bill that has not caught up to its value.
