YOUR MORTGAGE, EXPLAINED

Is my property tax assessment the same as my home’s market value?

Not necessarily. A tax assessment follows local rules and timing, while market value is an estimate of what a buyer may pay under current conditions. Different dates, exemptions and assessment methods can create differences. Use the local assessor for tax questions and appropriate market evidence for a sale or lending decision.

Identify the number

A notice may show assessed value, taxable value or another local measure. Read its definitions before comparing it with a listing price. An exemption may affect taxable value without changing a possible sale price.

Check the effective date

Assessments and market estimates may refer to different periods. A recent neighborhood sale does not automatically change the current bill. Ask the assessor how and when changes are reflected.

Use the right review process

If information is wrong, look up the official local correction or appeal process and deadlines. A lender or servicer cannot simply lower the assessment through an escrow adjustment.

Keep financing separate

Loan approval may require its own valuation process. A tax figure or online estimate is not automatically acceptable collateral value. Ask which value is being used and why.

Sources and scope

General U.S. education. Program, investor, company, servicer and state requirements vary. Agency references describe their own scope, not universal eligibility. Illustrations are hypothetical, not quotes or approvals.

Your next questions

What does my mortgage escrow account pay?

An escrow account is money your mortgage servicer collects and holds to pay certain property bills, commonly taxes and homeowners insurance. It is separate from principal and interest. Read your own statement to confirm which bills are included, which you still pay yourself and when the servicer expects to pay them.

Is an escrow shortage the same as higher taxes or insurance?

They are related but different. A higher tax or insurance bill changes the ongoing cost of owning your home. An escrow shortage means the account is below the amount needed under the analysis. A payment increase can include both. Paying the shortage does not automatically reverse the higher annual bill.

Escrow, lender reserves and emergency savings: what is the difference?

Escrow holds money for specified property bills. Lender reserves are assets a loan program may require you to have after closing. Emergency savings are cash you choose to keep for unexpected needs. These amounts can have different rules and purposes. Do not count money assigned to one job as freely available for another.

Why did I receive a property tax bill if my mortgage has escrow?

A bill or notice can be sent to you even when your servicer pays property taxes from escrow. Check the document, the account arrangement and the payment deadline. Do not assume every tax or assessment is included, and do not automatically pay twice. Confirm responsibility with the servicer and local tax office.
