What Is an Escrow Shortage, and Why Do New-Home Buyers Get Hit With One?
In this article
An escrow shortage means your mortgage escrow account does not have enough money in it to cover next year's property tax and insurance bills, so your servicer raises your monthly payment to catch up. It is not a late fee or a penalty. For buyers of newly built homes, it can show up in year two, because the first tax bill can be based on land or a partly finished house instead of the finished home.
What is an escrow shortage on a mortgage?
When you have an escrow account, part of your monthly payment goes into a separate account. Your servicer uses that money to pay your property taxes and homeowners insurance when the bills come due. The CFPB says an escrow account is ""set up by your mortgage lender to pay certain property-related expenses.""
Once a year, your servicer must review the account. This is called the escrow analysis. Under the federal escrow rule, 12 CFR 1024.17, the servicer uses that analysis to decide whether a surplus, a shortage or a deficiency exists. It then sends you an annual escrow statement within 30 days of the end of the escrow year.
Here is how the rule defines the three outcomes:
Shortage: the balance is lower than the target balance on the day of the analysis.
Deficiency: the balance is negative, because the servicer paid a bill before you had paid that money in.
Surplus: the balance is higher than the target balance.
Why did my escrow payment go up?
Your principal and interest stay the same on a fixed-rate loan. Your taxes and insurance do not. The CFPB puts it plainly: ""Your property taxes and insurance premiums can change from year to year. Your escrow payment—and with it, your total monthly payment will change accordingly.""
So a higher payment after the yearly review usually comes from two things at once:
The new escrow amount. Next year's bills are bigger, so each monthly deposit has to be bigger.
The shortage repayment. Last year's deposits did not keep up, so the account has a gap to fill.
That is why some buyers see their payment jump by more than the tax increase alone. They are paying for the higher bills going forward and catching up on the gap.
How do you pay back an escrow shortage?
You do not always have to write one big check. The federal rule gives the servicer set choices, based on how big the shortage is compared with one month's escrow payment (12 CFR 1024.17(f)(3)):
Size of the shortage | What the servicer may do |
|---|---|
Less than one month's escrow payment | Leave it alone, ask you to repay it within 30 days, or spread it over at least 12 monthly payments |
One month's escrow payment or more | Leave it alone, or spread it over at least 12 monthly payments |
A deficiency (a negative balance) has similar rules, and the servicer must tell you at least once a year if either one exists.
You can ask whether paying the shortage in one lump sum is an option. That keeps your new monthly payment lower but takes cash now.
How much can my servicer keep as a cushion?
Servicers may hold a little extra, called a cushion. Under 12 CFR 1024.17(c), it ""must be no greater than one-sixth (1/6) of the estimated total annual disbursements from the escrow account,"" or about two months of escrow payments. If the yearly review finds a surplus of 50 dollars or more and you are current, the servicer must refund it within 30 days.
What does an escrow shortage look like in real numbers?
Here is a simple EXAMPLE. These are made-up round numbers to show the math. They are not a quote and not anyone's real tax bill.
EXAMPLE only | Year 1 | Year 2 |
|---|---|---|
Yearly property tax estimate | $1,800 | $6,600 |
Yearly homeowners insurance | $3,000 | $3,000 |
Monthly escrow deposit for the year | $400 | $800 |
Shortage repayment (EXAMPLE $2,400 shortage ÷ 12) | none | $200 |
Escrow part of the monthly payment | $400 | $1,000 |
Largest cushion allowed (one-sixth of yearly bills) | $800 | $1,600 |
In this example, the escrow part of the payment goes from $400 to $1,000 a month. Only $400 of that jump is the higher tax bill. The other $200 is the catch-up, and it drops off after 12 months if nothing else changes.
Why can new-construction buyers get an escrow shortage in year two?
It comes down to timing. Florida is a good example. Under section 192.042 of the Florida Statutes, real property is assessed on January 1, and ""improvements or portions not substantially completed on January 1 shall have no value placed thereon."" So if your home was still a slab or a frame on January 1, that year's tax bill may cover only the land, or the land plus part of the home.
Now picture closing in the summer. Escrow is set from the smaller bill. The next January 1, your finished home is on the roll at full value, the bill that follows is much bigger, and the account comes up short.
Other states pick their own assessment dates and rules, so ask your county or parish tax office how a new home is valued where you are buying. We explain the Florida side in detail in how property taxes work on a newly built Florida home.
How do you avoid an escrow shortage on a new home?
You cannot stop taxes from rising, but you can stop them from surprising you:
Ask what tax number your escrow is built on. Before closing, ask whether the estimate uses the land-only bill or the finished home. You can ask for the higher figure.
Check your county's tax estimator, if it has one, using your contract price as a rough guide.
File for any exemption you qualify for. In Florida, the homestead exemption on a new home requires owning and living in the home on January 1 and filing by March 1.
Watch your insurance renewal. A higher premium shows up in the next escrow analysis.
Set money aside each month if you know the jump is coming.
In Florida, bills go out on November 1, and early payment earns a discount: 4% in November, 3% in December, 2% in January and 1% in February, under section 197.162. Most servicers pay escrowed tax bills for you, so the timing of that payment is part of your escrow math. See our guide to Florida property tax bill due dates for the full calendar.
What this means for new-construction buyers
A new home's first year can make your payment look lower than it will be. Compare homes using the finished home's taxes, not the land-only bill, and ask your lender to show both payments side by side. A resale home's tax bill already reflects a finished house, so first-year payments may not be an apples-to-apples match. Our guide to what escrow is when you buy a house covers the deposit side, too.
Common Questions
What is an escrow shortage?
An escrow shortage is the amount your escrow account is below the balance your servicer needs on the day it reviews the account. Federal rules define it as the amount by which the current balance falls short of the target balance at the time of the escrow analysis. It usually happens because property taxes or insurance went up.
Is an escrow shortage the same as an escrow deficiency?
No. A shortage means your balance is lower than the target but still positive. A deficiency means the account went negative because the servicer paid a bill with money you had not yet paid in. The rules for paying each one back are a little different.
Do I have to pay an escrow shortage all at once?
Not usually. If the shortage is one month's escrow payment or more, federal rules let the servicer either leave it alone or spread it over at least 12 monthly payments. A 30-day lump sum can only be required when the shortage is less than one month's escrow payment. You can ask your servicer if paying it in one lump sum is an option for you.
Why did my mortgage payment go up if my rate is fixed?
A fixed rate locks your principal and interest, not your taxes and insurance. The CFPB explains that when property taxes and insurance premiums change, your escrow payment and your total monthly payment change with them. A shortage repayment can be added on top of that new escrow amount.
Why can a new home get an escrow shortage in year two?
In Florida, property is valued on January 1, and a home that was not substantially complete that day gets no value for the unfinished building. So a new home's first tax bill can be based on the land, or the land plus a partly built home. If the escrow was set from that smaller bill, the first bill on the finished home can leave the account short.
Do I get money back if my escrow account has extra?
Yes, if you are current on your payments. When the yearly review finds a surplus of 50 dollars or more, the servicer must refund it within 30 days. A surplus under 50 dollars can be refunded or credited to next year's escrow payments.
