Mortgage escrow accounts: what your servicer collects, and why the payment moves
The mortgage payment you agreed to is not the payment you send. Most of it is principal and interest, fixed for the life of a fixed-rate loan; the rest is an escrow account that changes every year, and that is the part that surprises first-time buyers in month thirteen.
What the account is for
An escrow account — also called an impound account — is a holding account your servicer maintains to pay the bills that would otherwise arrive as painful annual lump sums. You pay one twelfth each month with your mortgage payment; the servicer pays the bill when it comes due. Typically inside the account:
- Property taxes, county and sometimes city or school district
- Homeowners insurance premiums
- Mortgage insurance, whether FHA annual MIP or conventional PMI
- Flood insurance where the property is in a mapped flood zone
- Occasionally special assessments levied by the taxing authority
Normally outside the account: homeowners association dues, which you pay directly to the HOA even though underwriting counts them in your debt ratio, and utilities.
The arithmetic, and the cushion
The base monthly figure is simply the total of the escrowed bills for the coming year divided by twelve. On top of that, federal escrow rules under Regulation X allow the servicer to keep a cushion of no more than one sixth of the annual total — two months of escrow payments — as a buffer against a bill arriving higher or earlier than projected. Two months is a ceiling, not a requirement; nothing in federal law obliges a servicer to collect any cushion at all, and some collect less. State law occasionally tightens the limit further.
| Line | Illustrative annual | Monthly |
|---|---|---|
| Property taxes | $4,200 | $350 |
| Homeowners insurance | $1,800 | $150 |
| Mortgage insurance | $1,200 | $100 |
| Escrow portion of the payment | $7,200 | $600 |
Those figures are illustrative round numbers, not a quote. Taxes in particular swing enormously by state and county — the state pages give the approximate effective property tax rate where you are buying, which is the fastest way to sanity-check a lender’s estimate before you fall in love with a house.
The annual escrow analysis
Once a year the servicer runs an escrow account analysis: it compares what it collected against what it paid, projects the next twelve months, and mails you an annual escrow account statement showing the new monthly figure. Three outcomes are possible.
Shortage
The account came up short of its target balance, almost always because a tax bill or insurance premium rose. Your payment goes up twice over — once for the higher ongoing bills, and again to refill the gap. Federal rules let you repay a shortage in equal installments over at least twelve months, and you may also write a check for it in one go, which avoids carrying the second increase for a year.
Surplus
The account holds more than the target plus permitted cushion. If the surplus is $50 or more and your loan is current, the servicer generally refunds it within 30 days of the analysis; below $50 it may be refunded or credited against future payments.
Deficiency
The balance actually went negative — the servicer advanced its own money to pay a bill. This is treated more strictly than a shortage and repayment terms are shorter.
The first-year trap
The single most common escrow shock for new buyers is the first reassessment. Your estimated escrow at closing may have been built on the seller’s tax bill, which can reflect a homestead or senior exemption you do not get, an assessed value years behind the price you just paid, or — on new construction — a lot with no house on it yet. When the county reassesses at your purchase price, the tax line can jump by hundreds of dollars a month, producing a shortage and a higher payment in the same statement.
Ask the closing agent, before you sign, what the taxes will be under your ownership rather than the seller’s. Then set aside the difference for a year. Nothing about this is a lender error, and there is no mechanism to undo it — the money is genuinely owed to the county.
Waiving escrow
Escrow is not always optional and not always required. FHA loans require it, and VA and USDA lenders effectively always require it. On a conventional loan many lenders will waive escrow when the loan-to-value ratio is at or below 80%, usually for a small fee or a slightly higher rate, since the lender is giving up its guarantee that the taxes get paid. Separately, federal rules require an escrow account for at least five years on higher-priced mortgage loans, regardless of preference.
Waiving suits disciplined savers who would rather hold the cash and earn on it for the year. It suits nobody who might spend it. A missed property tax bill leads to a tax lien with priority over the mortgage — the one bill you cannot let slide. If you are already at 80% LTV, look at the PMI removal rules in the same conversation; both hinge on the same threshold.
Frequently asked questions
Why did my mortgage payment go up if I have a fixed-rate loan?
Principal and interest are fixed; taxes, insurance and any mortgage insurance are not. A fixed-rate payment that rises is almost always the escrow portion adjusting after the annual analysis, and the statement will itemize which line moved.
Can I pay an escrow shortage in one lump sum?
Usually yes, and it is often the better choice — it removes the twelve-month repayment surcharge, leaving only the increase for the higher ongoing bills. Call the servicer and confirm how to apply the payment so it is credited to escrow, not to principal.
Do I earn interest on my escrow balance?
Only in the handful of states whose law requires servicers to pay interest on escrow funds. Federal law does not require it, so in most states the balance sits idle.
Does the escrow deposit at closing count as a closing cost?
It appears on the Closing Disclosure and it is cash you must bring, but it is a prepaid item rather than a fee — the money remains yours, held to pay your own bills. Our closing costs guide separates the fees from the prepaids.
