Property Taxes and Escrow Explained

When most people budget for a mortgage, they focus on the interest rate and principal payment. But your actual monthly obligation is almost always higher — because your lender bundles property taxes and insurance into a single payment called PITI. Understanding how this works, how your escrow account is managed, and what happens when the numbers change will help you avoid unwelcome surprises and keep your housing costs under control.

What Are Property Taxes?

Property taxes are levied by local governments — counties, municipalities, and school districts — to fund services like public schools, roads, emergency services, and parks. The amount you owe is based on two factors: the assessed value of your home and the local tax rate, often called a mill rate.

Assessed Value vs. Market Value

Your home's assessed value is determined by the local tax assessor and is often — but not always — close to market value. Many jurisdictions assess at a fixed percentage of market value, such as 80% or 100%. If your home is worth $400,000 and your county assesses at 100% of market value, the assessed value is $400,000. If the local mill rate is 15 mills (1.5%), your annual property tax bill would be $6,000.

Mill Rates and How They Vary

Mill rates differ dramatically by location. A mill represents $1 of tax per $1,000 of assessed value. A mill rate of 10 means $10 per $1,000, or 1% of assessed value annually. Rates in low-tax states like Alabama or Hawaii can be well below 0.5%, while parts of New Jersey and Illinois regularly exceed 2.5%. When comparing homes in different areas, property taxes can easily add or subtract hundreds of dollars per month from your true cost of ownership.

How Escrow Accounts Work

Rather than requiring you to pay a large property tax bill once or twice a year, most lenders collect a portion of your estimated annual tax obligation with every monthly mortgage payment. This money is held in an escrow account — a separate, lender-managed account — and disbursed to the taxing authority when the bill comes due.

The same account typically holds your homeowners insurance premium. Together, these items make up the "TI" in PITI: Principal, Interest, Taxes, and Insurance. When a lender quotes you a monthly payment, ask whether it includes PITI or just principal and interest (P&I), since the difference can be significant.

Your Full PITI Payment

On a $400,000 loan at 7.00% for 30 years, the P&I payment is about $2,661. Add $500/month for property taxes ($6,000 annually) and $150/month for homeowners insurance ($1,800 annually), and your PITI climbs to roughly $3,311 — 24% higher than the P&I alone.

The Initial Escrow Deposit at Closing

When you close on a home, you will not only start your escrow account — you will be required to fund it with an initial deposit. Federal law (RESPA) allows lenders to collect up to two months of escrow payments as an initial cushion, in addition to the prepaid amounts needed to bring the account current to your first payment date.

In practice, this means your closing costs will include a line item labeled "Initial Escrow Payment at Closing" or "Prepaids." On a home with $6,000 in annual taxes and $1,800 in annual insurance, that upfront escrow deposit could run $1,300–$1,500 or more depending on the timing of your close date relative to the next tax due date.

This is one of the most commonly underestimated closing costs. Our closing cost calculator includes escrow prepaids in its estimates so you can budget accurately for what you will owe at the table.

Annual Escrow Analysis and Adjustments

Your lender is required by law to perform an escrow analysis at least once a year. The analysis reviews what was collected, what was paid out, and what the account balance looks like going forward. Because property taxes and insurance premiums change — often upward — your required monthly escrow contribution will likely change too.

Escrow Shortfall

A shortfall occurs when your escrow account does not have enough funds to cover upcoming disbursements. This typically happens when your property tax assessment increases, your insurance premium rises, or both. When the analysis reveals a shortfall, your lender will notify you with two options: pay the deficit in a lump sum, or have it spread across your next 12 monthly payments, increasing your PITI temporarily. Lenders are required to send this notice at least 30 days before the change takes effect.

Escrow Surplus

If your account has more than one month's worth of cushion over the required minimum after the analysis, federal law requires your lender to refund the excess to you — typically as a check or direct deposit. A surplus usually means your taxes or insurance came in lower than estimated. Enjoy the refund, but remember that next year's analysis could swing the other direction.

Waiving Escrow: Is It an Option?

Some borrowers prefer to manage property taxes and insurance themselves and pay in lump sums rather than through an escrow account. This is sometimes allowed, but comes with conditions.

Most conventional loans allow escrow waivers if your loan-to-value ratio is below 80% — meaning you have at least 20% equity. FHA and VA loans, however, generally require escrow accounts for the life of the loan regardless of equity. When a waiver is granted on a conventional loan, lenders often charge a small fee (typically 0.125%–0.25% of the loan amount added to the rate) to compensate for the additional risk they assume if you fail to pay your tax bill and the government places a lien on the property.

Self-managing your escrow requires discipline: you need to set aside the right amount each month in a separate savings account and make sure the payment is sent before the due date. Missing a property tax payment can result in penalties, interest, and in extreme cases, a tax lien that takes priority over your mortgage.

How to Appeal Your Property Tax Assessment

If you believe your home has been over-assessed — meaning the taxing authority thinks your home is worth more than it actually is — you have the right to appeal. A successful appeal can lower your annual tax bill permanently, reducing both your escrow payment and the total cost of homeownership.

The appeals process varies by jurisdiction, but generally involves:

Review your assessment notice carefully. When you receive your annual assessment, check the assessed value against recent comparable sales (comps) in your neighborhood. If similar homes sold for less than your assessed value, you have a basis for appeal.

Gather evidence. Pull three to five recent sales of comparable homes — similar size, age, condition, and location — from public records or real estate sites. Document any condition issues with your property that might reduce its value relative to comps.

File a formal appeal. Most counties have a deadline of 30–90 days after the assessment notice is issued. Miss it and you wait another year. The appeal is typically heard by a local review board; many decisions are made based on written submissions alone.

Property tax appeals succeed surprisingly often — particularly after a fast-rising market corrects or when assessors rely on automated models that miss property-specific issues. Even a 10% reduction in assessed value on a $400,000 home at a 1.5% tax rate saves $600 per year — and reduces your escrow payment by $50 per month going forward.

The Bottom Line

Property taxes and escrow are not optional details — they are core components of your monthly housing cost and your total cost of homeownership. A home in a high-tax jurisdiction can cost hundreds of dollars more per month than an otherwise identical home across a county line. Understanding how your escrow account is funded, analyzed, and adjusted puts you in control of your budget rather than being caught off guard by a shortfall notice or a closing-day escrow deposit that exceeds your estimate.

Before you make an offer, research the property tax history for the specific address and model the full PITI payment — not just the principal and interest. Our mortgage calculator and affordability calculator both let you include taxes and insurance so your numbers reflect reality from the start.
