Where to find your property value right now

Your property value is public record in most places, and you can find it through your county assessor's office, which maintains records on every parcel of land and building in the county. Start by visiting your county assessor's website (search "[your county] assessor" online) and look for a search tool or database—most let you search by address or parcel number. The assessor's estimate is what your property is worth for tax purposes, not always what it would sell for, but it is a solid starting point.

If your county assessor's site is hard to navigate or doesn't have an online tool, call the assessor's office directly. They can tell you the assessed value over the phone or mail you a property record card. You can also visit in person if you live close enough; many offices keep records available during business hours.

Beyond the assessor, three other sources give you different angles on value: real estate websites like Zillow and Redfin show estimated market values (what homes like yours have sold for recently), your mortgage lender's records show what you paid and what they think it's worth now, and a professional appraiser can give you a formal valuation if you need it for a loan or legal matter.

Key Takeaways

  • Your county assessor's office keeps the official property record and can tell you the assessed value by phone, website, or in person.
  • Real estate websites like Zillow and Redfin show estimated market values based on recent sales of similar homes in your area.
  • Assessed value (for taxes) and market value (what it would sell for) are usually different numbers, so check both.
  • A professional appraiser gives you a formal valuation if you need it for refinancing, a home equity loan, or legal purposes.
  • Property records are public, so you can look up your neighbors' values too to see what homes like yours are worth.

Using your county assessor's database

The assessor's database is the official source because it is maintained by the government office responsible for property tax. When you search your address, you will see the assessed value, the land value, the building value, and sometimes the year it was last assessed. Some counties reassess every year; others do it every three to five years. The assessed value may lag behind actual market conditions, especially in fast-moving real estate markets.

Write down your parcel number while you are in the database—it is a unique identifier for your property and makes it easier to reference if you call the assessor's office later. If the assessed value seems wrong (too high or too low), most counties allow you to file a formal challenge called an appeal or protest, usually once a year. The assessor's office can tell you the deadline and what documents you need.

Reading estimates from real estate websites

Zillow, Redfin, Trulia, and similar sites use recent sales data and property details to estimate what your home is worth on the open market. These estimates are called automated valuation models (AVMs) and they are useful for getting a ballpark figure, but they are not appraisals and they can be off by thousands of dollars, especially if your home is unusual, recently renovated, or in a neighborhood where few homes have sold recently.

To use these sites, search your address and look for the "Zestimate" (Zillow), "Redfin Estimate," or similar label. The site will show you the estimate, the range of uncertainty around it, and a list of comparable homes that sold nearby. Pay attention to the date of those sales—if the most recent comparable sale was two years ago, the estimate may not reflect current market conditions. You can also see what your neighbors' homes are estimated at, which gives you context for your own value.

These estimates update as new sales data comes in, so if you check again in a few months, the number may change. They are free and quick, but they should not be your only source if you need an accurate value for a major financial decision.

When to get a professional appraisal

A professional appraiser is a licensed person who inspects your home in person, compares it to recent sales of similar homes, and produces a formal written report. You need an appraisal if you are refinancing a mortgage, taking out a home equity loan, or dealing with a legal matter like a divorce or estate settlement. The appraisal is binding for the lender's purposes and carries more weight than an online estimate.

Appraisals cost between $300 and $700 depending on your home's size and location. If you are refinancing, your lender will order and pay for the appraisal. If you want one for your own information, you can hire an appraiser directly—search "[your city] certified appraiser" or ask your real estate agent for a referral. The appraisal takes one to two weeks to complete after the inspector visits.

Comparing assessed value and market value

These two numbers often confuse people because they measure different things. Assessed value is what your county thinks your property is worth for property tax purposes. Market value is what a buyer would pay for it today. Assessed value is usually lower than market value, but not always—it depends on when the last assessment happened and how fast your local real estate market has moved.

For example, your assessed value might be $250,000 (set five years ago), but Zillow might estimate your market value at $320,000 (based on recent sales). If you are selling, the market value is what matters. If you are disputing your property taxes, the assessed value is what you want to challenge. If you are borrowing against your home, the lender will order an appraisal to get their own number, which may differ from both.

Using property value to make financial decisions

Once you know your property value, you can calculate your home equity—the difference between what your home is worth and what you owe on your mortgage. If your home is worth $350,000 and you owe $200,000, your equity is $150,000. This number matters if you are thinking about a home equity loan, a line of credit, or refinancing.

You can also use your property value to understand your net worth, compare your home's value to others in your neighborhood, or decide whether to invest in repairs or upgrades. If your assessed value has jumped significantly, it might mean your property taxes will rise at the next reassessment—check your county's reassessment schedule so you are not surprised.

Frequently Asked Questions

How often does my property value get reassessed?

It depends on your state and county. Some reassess every year, others every three to five years. Check your county assessor's website or call to find out the schedule for your area. You can also look at your property record card to see when the last assessment was done.

Can I dispute my assessed value if I think it is too high?

Yes. Most counties allow you to file a formal appeal or protest once a year, usually within a set window (often 30 to 60 days after you receive your assessment notice). The assessor's office can tell you the deadline and what documents you need—usually comparable sales or a recent appraisal showing a lower value.

Why is my Zillow estimate so different from my assessed value?

Assessed value is set for tax purposes and may not update every year, while Zillow's estimate changes as new sales data comes in. Zillow also uses a different calculation method than the assessor. For the most accurate number, compare your Zillow estimate to recent sales of similar homes in your neighborhood, or get a professional appraisal.

Do I need an appraisal to know my home's value?

No. You can get a free estimate from Zillow or Redfin, or check your assessed value through the county. An appraisal is only necessary if you are refinancing, taking out a loan, or need a formal valuation for legal reasons.

What if my home is unique or very old—will online estimates work?

Online estimates work best for homes that are similar to others in the area with recent sales. If your home is unusual, historic, or sits on a large lot with few comparables, the estimate may be less accurate. In that case, a professional appraisal is worth the cost for a reliable number.
