Aggregate Adjustment in Your Mortgage | GO Mortgage

When you’re gearing up to close on your new home, every dollar matters—especially those listed on your final mortgage paperwork. One often misunderstood item is the aggregate adjustment, a small line item that can have a big impact on your closing costs and your future escrow payments.

Let’s break down exactly what an aggregate adjustment is, how it works, and why it’s actually there to protect your money, not take more of it.

What is an aggregate adjustment?

An aggregate adjustment is a calculation your lender uses to make sure you’re not being overcharged for your escrow account at closing. It’s part of your final loan settlement and appears on your Closing Disclosure.

Think of it as a balancing act: Lenders need to collect enough money to fund your escrow account, but federal law prohibits them from collecting too much. The aggregate adjustment helps ensure they strike that balance.

How aggregate adjustments protect you

Mortgage lenders are required to comply with the Real Estate Settlement Procedures Act (RESPA), which limits how much cushion they can keep in your escrow account. 

Specifically, RESPA caps that cushion at no more than one-sixth (or two months) of your annual tax and insurance costs.

If the initial escrow payments would result in exceeding this cushion, your lender must issue an aggregate adjustment to lower the amount you fund upfront. 

This prevents overcollection and ensures you’re only paying what’s necessary to keep your account balanced.

What to expect in your Loan Estimate

When you apply for a mortgage, your lender is required to give you a Loan Estimate within three business days. 

This document outlines the expected costs of your loan, including:

• Your interest rate and monthly payment
• Projected property taxes and homeowners’ insurance
• Any upfront costs like loan origination or title fees
• An estimate of your escrow funding and potential aggregate adjustment

At this stage, the numbers are still estimates. Your escrow contributions may change as your closing date approaches, especially if your tax or insurance quotes are updated.

Your Closing Disclosure: Finalizing the numbers

At least three business days before closing, you’ll receive a Closing Disclosure with final figures. Here’s where the aggregate adjustment comes into play.

The Closing Disclosure will list:

• Final escrow deposits
• The aggregate adjustment (as a credit or debit)
• Final interest rate and loan terms
• Total closing costs

If your escrow deposits exceed what’s legally allowed, the aggregate adjustment reduces your required contribution. It’s a borrower-friendly correction, designed to maintain fairness and transparency.

Escrow accounts: Year-to-year impact

Your escrow account continues to play a role in your homeownership long after closing. 

Each year, your lender performs an escrow analysis to check whether the monthly payments you’ve been making are still enough to cover taxes and insurance.

If those costs increase, you may face a shortage. If they go down or are overestimated, you may see a surplus.

Handling a shortage: Your repayment options

Escrow shortages happen when property taxes or insurance premiums increase, and your current monthly contributions aren’t enough to keep up. 

When that occurs, your lender will notify you and offer two repayment options:

1. Pay the full shortage as a lump sum
2. Spread the shortage over 12 months, adding it to your monthly mortgage payment

For example, if you’re short $600, you could pay it all at once—or simply add $50 to your monthly payments for the next year.

Surplus refunds: What happens when you overpay

Sometimes, your lender collects more than necessary, often due to tax reductions or changes in insurance policies. In that case, you’ll have an escrow surplus.

If the surplus is $50 or more, you’ll usually get a refund check. If it’s less than $50, your lender may leave it in your account to offset any future increases.

You can also request to keep the surplus in your escrow account as a cushion against next year’s fluctuations.

Budgeting tips: Avoid escrow surprises

You can’t always predict changes in your escrow balance, but a little planning goes a long way. Here’s how to stay ahead of the curve:

• Review mail from your county tax assessor or homeowners insurance provider—rate hikes often show up here first
• Ask your lender for a mid-year escrow analysis if your insurance premium increases significantly
• Keep a small buffer in your budget for unexpected escrow adjustments each year

Why your first year’s escrow payments may feel “off”

Many homeowners are surprised when their monthly mortgage payment appears to fluctuate within the first year, often due to an escrow “catch-up” effect or changes in property taxes after the purchase.

Here’s what’s happening behind the scenes

When you buy a home, your initial escrow estimate is based on the seller’s tax and insurance figures. 

However, local taxing authorities often reassess your property after the sale, especially if the purchase price is significantly higher than the previous assessed value.

This can result in:

• Higher property taxes than initially projected
• An escrow shortage in your first annual analysis
• An unexpected increase in your monthly mortgage payment

Although your lender didn’t “miss” anything, the reassessment happened after closing. That’s why your escrow may need to be rebalanced within the first 12 months.

Pro tip: If you’re buying in a rapidly appreciating market, ask your lender to run a “what-if” scenario using your purchase price as the projected tax basis. This can help you plan ahead and avoid payment shock.
