Escrow Explained: What It Is and How It Works

Escrow means two different things in a mortgage. During your home purchase, it's a neutral third party that holds funds and documents until closing. After you own the home, it's an account your lender uses to collect and pay your property taxes and insurance. Both protect you.

Escrow during the purchase

When you're buying, "escrow" refers to a neutral third party (an escrow company or agent) that holds your earnest money deposit, the purchase funds, and key documents while the sale is being finalized. Neither you nor the seller controls that money directly, which protects both sides: the seller knows the funds exist, and you know your deposit isn't released until the conditions of the sale are met. It's a core part of the home buying process, the mechanism that lets two parties who don't know each other transact safely, and it works alongside the other money you bring to the table, like your closing costs.

Escrow after you own the home

Once you're a homeowner, escrow usually means your escrow account (sometimes called an impound account). Your lender collects a portion of your annual property taxes and homeowners insurance with each monthly payment, holds it, and pays those bills when they come due. This is why your monthly payment is more than just principal and interest, it includes those escrowed amounts, part of the full PITI payment (principal, interest, taxes, insurance).

Why lenders require escrow accounts

Lenders want your property taxes and insurance paid, because unpaid taxes can become a lien ahead of their mortgage, and a lapsed insurance policy leaves their collateral unprotected. Escrowing these bills guarantees they get paid on time. For most loans with less than 20% down, an escrow account is required; with 20% or more equity you can sometimes waive it and pay taxes and insurance yourself, though many homeowners keep escrow for the convenience of spreading those big bills across 12 months.

Escrow analysis and why your payment can change

Once a year, your lender runs an escrow analysis to check whether they collected the right amount. If your property taxes or insurance premiums went up, your escrow portion, and your monthly payment, will rise to cover it. If they over-collected, you may get a refund. This is why a fixed-rate mortgage payment can still change year to year: the principal and interest stay fixed, but the escrowed taxes and insurance move. It's worth understanding so an increase doesn't catch you off guard.

The shortage or surplus at year-end

If your taxes or insurance rose more than expected, you can end the year with an escrow shortage, and the lender will either ask for a lump sum or (more commonly) spread the shortfall across your next 12 payments, raising them. A surplus works the opposite way. None of this is a penalty, it's just the account truing up to real costs. Knowing it happens helps you plan for the possibility of a payment adjustment each year.
