What Is an Escrow Account, and What Is an Escrow Shortage?

Short answer: An escrow account is an account your mortgage company uses to pay your property taxes and homeowners insurance for you. Part of each monthly payment goes into it, and the servicer pays those bills when they come due. An escrow shortage means the account balance came in below the target when the servicer did its yearly review. Because taxes and insurance can change, your payment can change even with a fixed rate.

Escrow confuses a lot of first-time buyers, usually the first time the payment goes up. Let's make this simple.

What is an escrow account on a mortgage?

An escrow account, also called an impound account, is set up by your mortgage lender to pay certain property-related expenses. The servicer, which is the company that collects your payment, takes part of each payment and holds it for your property taxes and homeowners insurance.

Your monthly payment then has two parts: principal and interest, plus the escrow amount. On a fixed-rate loan, the principal and interest stay the same. The escrow part can move.

This is different from the escrow you hear about while buying a home. That one is the closing process, handled by a title company or escrow office. The escrow account starts after closing and runs for as long as your loan requires it.

Do you have to have an escrow account?

Often, yes. The Consumer Financial Protection Bureau (CFPB) says many lenders require one, and sometimes the law does. Your loan documents will say whether yours does, so ask your lender before closing.

If you do not have one, you pay those bills yourself. VA's Buyer's Guide warns that failing to pay your taxes can lead to a tax lien on your home and could lead to foreclosure.

How much money can they keep in escrow?

Federal rules set a limit. Under Regulation X, the servicer can collect one-twelfth of your expected yearly tax and insurance bills each month. It can also keep a cushion of up to one-sixth of those yearly bills, which works out to about two months of escrow payments.

Here is a made-up example, not a Las Vegas estimate. Say your taxes and insurance total $4,800 a year:

• Your monthly escrow amount would be $400.
• The largest cushion allowed would be $800.

You also fund the account at closing. That is why your closing paperwork shows escrow money on top of your other costs.

What is an escrow analysis?

An escrow analysis is the servicer's yearly check of what the account collected, what it paid, and what it needs next year. Federal rules require the analysis at the end of each escrow account year. You also get an annual escrow statement within 30 days after that year ends.

Your first statement, the initial escrow account statement, comes at closing or within 45 days after it.

Read the annual statement when it shows up. It tells you if you owe money, if you are owed money, and what your new payment will be.

What is an escrow shortage?

An escrow shortage means your current balance is lower than the target balance at the time of the analysis. It usually happens because a tax or insurance bill came in higher than the servicer planned for.

Your servicer's options depend on the size of the shortage:

• Less than one month's escrow payment. The servicer can do nothing, ask you to repay it within 30 days, or spread it over at least 12 months.
• One month's escrow payment or more. The servicer can do nothing, or spread it in equal payments over at least 12 months.

Back to the example. Say your bills rise to $5,400 a year and the analysis finds a $240 shortage. Your new escrow amount would be $450 a month. If the servicer spreads the $240 over 12 months, you pay $20 more on top, for $470 a month in escrow.

So a payment increase usually has two pieces: the higher bills going forward, and catching up on the shortage. Once the shortage is repaid, that catch-up part ends.

How is a shortage different from a deficiency or a surplus?

These three words sound alike and mean different things:

• Shortage. The balance is positive but below the target.
• Deficiency. The balance is negative. The servicer paid a bill with its own money, and you owe it back.
• Surplus. The balance is above the target. If the surplus is $50 or more and your payments are current, the servicer must refund it within 30 days of the analysis. If it is under $50, the servicer can refund it or credit it to next year.

Who makes sure your taxes actually get paid?

The servicer has to pay on time, and you should still check. Under federal rules, the servicer must pay escrow bills on or before the deadline to avoid a penalty, as long as your mortgage payment is not more than 30 days overdue. It has to advance its own money if the account runs short, then it can collect that money back from you.

In Clark County, property taxes come due in four installments: the third Monday in August, and the first Monday in October, January, and March. The Clark County Treasurer says it is your responsibility to make sure your mortgage company pays on time. You can check status on the Treasurer's property tax site.

If a tax bill lands in your mailbox and your mortgage company holds escrow, the Treasurer says to write your loan number on it and send it to your mortgage company. If your servicer missed a payment, the CFPB says to contact the tax office or insurance company as soon as you can and send the servicer a written notice of error.

Common escrow mistakes

• Thinking a fixed rate means a fixed payment. Only principal and interest are fixed. Taxes and insurance can change every year.
• Throwing away the annual statement. That page explains any change in your payment before it surprises you.
• Keeping an old autopay amount. If you set a fixed amount at your bank, it will not change when your payment does. Ask your servicer how a change gets handled.
• Not telling the servicer about an insurance change. If you switch insurance companies, the servicer needs the new policy so it pays the right bill.
• Assuming the seller's tax bill will be yours. Ask your lender how they estimated your taxes before you budget around that number.

Frequently asked questions

What is an escrow account in a mortgage?

It is an account set up by your mortgage lender to pay certain property-related expenses, usually property taxes and homeowners insurance. Part of each monthly payment goes into it, and the servicer pays those bills for you.

What is an escrow shortage?

An escrow shortage means your current escrow balance is lower than the target balance at the time of the yearly analysis. It usually happens when a tax or insurance bill comes in higher than expected.

Why did my mortgage payment go up if I have a fixed rate?

The escrow part of your payment probably changed. A fixed rate keeps principal and interest the same, but property taxes and insurance premiums can change from year to year.

Do I have to pay an escrow shortage all at once?

Not when the shortage equals one month's escrow payment or more. Federal rules let the servicer spread that repayment over at least 12 months, but not demand it all at once. If the shortage is less than one month's payment, the servicer can ask you to repay it within 30 days.

Do I get money back if there is extra in my escrow account?

If the surplus is $50 or more and your payments are current, the servicer must refund it within 30 days of the analysis. If it is under $50, the servicer can refund it or credit it to next year's escrow payments.
