Why did my Arizona escrow payment go up?

How an escrow account works

With an escrow (or impound) account, part of each monthly mortgage payment goes into an account the servicer uses to pay your property tax bill and insurance premium, according to the CFPB. When those bills go up or down, your monthly payment goes up or down too.

The most common reasons it goes up

• Property taxes rose. In Arizona, tax bills come in two halves due October 1 and March 1, and the bill depends on the home's value, its classification and the tax rates and special district charges on it. See when Arizona property taxes are due and how they're calculated.
• Insurance went up. Arizona's insurance department says premiums are rising statewide. See what affects homeowners insurance cost.
• The account came up short. If last year's bills were higher than the servicer projected, the analysis finds a shortage, which gets added on top of the higher monthly amount (more below).

The CFPB lists other reasons a total payment can change that have nothing to do with escrow: a temporary buydown ending, an adjustable rate resetting, an interest-only period ending, a change in private mortgage insurance, or new fees.

What the federal escrow rules say

• Yearly analysis and statement. The servicer must analyze the account and send you an annual escrow statement within 30 days of the end of the escrow year (12 CFR §1024.17).
• Cushion limit. The servicer can hold a cushion of no more than one-sixth of the year's estimated escrow payments, about two months' worth.
• Shortage under one month's escrow payment. The servicer can leave it alone, ask you to repay it within 30 days, or spread it over at least 12 months.
• Shortage of one month's escrow payment or more. The servicer can leave it alone or spread it in equal monthly payments over at least 12 months.
• Surplus. If you're current on payments and the surplus is $50 or more, the servicer must refund it within 30 days of the analysis. Under $50, it can refund it or credit it to next year.

How to check your escrow increase

1. Find the annual escrow statement and compare last year's actual tax and insurance payments with this year's projection.
2. Look up the tax bill on the county treasurer's site and your current insurance declarations page. Check that the servicer used the right amounts.
3. If a shortage is spread over 12 months, you can ask whether a voluntary lump-sum payment would clear it. The CFPB's servicing FAQs say a servicer may accept an unsolicited lump-sum payment, though it can't list that as a required option on the escrow statement. The monthly escrow amount will still reflect the higher bills.
4. If you think the servicer made a mistake, the CFPB suggests calling first, then sending a written notice of error to the address the servicer lists for errors and information requests, which can differ from the payment address.

Buying? Plan for taxes and insurance from day one

Taxes and insurance vary a lot from home to home, even on the same street. Seeing each home's actual tax bill and an insurance estimate before you tour makes later escrow changes less of a surprise.
