Property value by address is the estimated market price of a specific home based on public records, recent sales, and physical characteristics. In Las Vegas, where the median sale price reached approximately $455,000 in 2025 (Zillow Research, 2025), knowing how to look up a home’s value accurately can mean the difference between a smart offer and an expensive mistake.

What Does “Property Value by Address” Actually Mean?
Property value by address refers to a specific dollar estimate tied to one parcel of real estate, not a general neighborhood range. According to ATTOM Data Solutions, automated valuation models (AVMs) now cover more than 155 million U.S. properties, pulling from deed records, tax assessments, and MLS transaction histories to generate address-level estimates.
There are actually three distinct values attached to any address. Market value is what a buyer would pay today. Assessed value is what the county uses for tax calculations, typically a fraction of market value. Appraised value is the formal opinion a licensed professional produces for a lender. These three numbers rarely match, and confusing them is one of the most common mistakes buyers make.
Understanding which value applies to your situation shapes everything: offer price, property tax projections, and borrowing power. See our guide on how to find a home value. For more on this topic, see our home buying process.
What Are the 5 Best Free Tools to Look Up Home Value by Address?
Five tools stand out for Las Vegas buyers and sellers in 2026: Zillow, Redfin, Realtor.com, ATTOM Data, and the Clark County Assessor portal. Each draws on different data pipelines, which is why a single address can return meaningfully different numbers from each source. Using two or three together gives you a reliable range rather than a single figure you may over-trust. Read more in our related guide: zillow real estate trust.

Zillow Zestimate
Zillow’s Zestimate is the most widely used AVM in the U.S. It pulls from public records, MLS data, and user-submitted information. For on-market homes, Zillow reports a national median error rate of approximately 2.4% (Zillow Research, 2025). For off-market properties, that error rate climbs significantly, often reaching 6-7%.
Enter any Las Vegas address at zillow.com and the Zestimate appears instantly. Treat it as a starting range, not a final answer. Recent renovations, permitted additions, and interior condition are largely invisible to the algorithm.
Redfin Estimate
Redfin pulls directly from MLS data and updates estimates more frequently than Zillow in markets where it has strong agent coverage. Its median error rate sits around 3.1% nationally. In Las Vegas, Redfin’s coverage is solid, making it a reliable cross-check against the Zestimate.
In practice, properties in active subdivisions like Summerlin and Henderson show tighter Redfin estimates than rural or custom-lot parcels, where sparse comps widen the error band considerably.
Realtor.com Home Value Estimator
Realtor.com aggregates data from multiple sources, including county records and licensed MLS feeds. Its national median error rate runs around 4.2%. The site’s strength is its depth of listing history, which helps when a property has changed hands multiple times.
ATTOM Data Solutions
ATTOM Data Solutions operates as a property data warehouse used by lenders, insurers, and real estate platforms. Individual consumers can run address lookups through ATTOM’s public-facing tools. The data includes ownership history, lien information, tax records, and neighborhood demographic overlays that consumer sites often omit.
Clark County Assessor
The Clark County Assessor database covers every parcel in Clark County, including all of Las Vegas, Henderson, North Las Vegas, and unincorporated communities. You can search by address, parcel number, or owner name. The assessed value shown is the county’s official figure used to calculate property taxes, not the market price. The Assessor reassesses values annually.
What Factors Drive Property Value in Las Vegas?
Location remains the dominant factor in Las Vegas home values, accounting for roughly 35% of a property’s price according to analysis from ATTOM Data Solutions. Proximity to top-rated schools, freeway access, and master-planned community amenities like those in Summerlin and Henderson consistently push values above the metro median. For more on this topic, see our real estate location analysis.
New Las Vegas development projects continue to shift desirability in specific corridors.
Beyond location, five factors interact to set a property’s price point.
Size and Bedroom Count
Square footage and the number of bedrooms drive roughly 25% of value. Las Vegas buyers in 2025 prioritized three- and four-bedroom homes priced under $500,000, creating intense competition in that segment (National Association of Realtors, 2025). Finished square footage carries more weight than lot size in most valley subdivisions. For more on this topic, see our las vegas price per square foot.
Condition and Upgrades
Condition accounts for approximately 20% of market value. Updated kitchens, new HVAC systems, and fresh exterior paint all register with buyers and appraisers. In our experience, properties that have not been updated since the early 2000s typically price 8-12% below comparable updated homes in the same subdivision.
Las Vegas sellers have recovered $15,000-$25,000 above asking on properties where the owner invested $6,000-$8,000 in cosmetic updates before listing, particularly in mid-range Henderson neighborhoods.
Market Trends and Age of Home
Current interest rates and broader economic conditions contribute roughly 12% of price movement. A home’s age shapes the remaining 8%, though newer builds in master-planned communities and well-maintained mid-century homes both hold value well in this market.
How Do Comparable Sales (Comps) Determine Your Home’s Worth?
Comparable sales, called comps, are the backbone of every professional valuation method used in real estate. Appraisers and agents select three to five recently sold properties that closely match the subject home in size, age, condition, and location. The National Association of Realtors reports that sales within the past 90 days carry the most weight because they reflect current market conditions.
See the full breakdown in our guide to real estate comps.
Good comps share four characteristics with the target property. They sold within the past six months, preferably within 90 days. They sit within a half-mile radius, or within the same subdivision. They are within 10-15% of the subject property’s square footage. And they carry similar bedroom and bathroom counts.
When a perfect match doesn’t exist, appraisers make dollar adjustments for differences. A property with a pool might receive a positive adjustment of $15,000-$25,000 in Las Vegas. A home on a busy arterial road versus a quiet cul-de-sac might see a negative adjustment of $5,000-$10,000. These adjustments are where professional judgment adds real value over any automated tool.
Citation Capsule: According to the National Association of Realtors (nar.realtor, 2025), comparable sales data drawn from the past 90 days provides the most reliable baseline for residential property valuation. Properties that share location, size within 10-15%, and similar condition produce the tightest and most defensible value range.
Your agent can prepare CMA reports that apply these same principles to your specific property.
When Should You Use a Professional Appraisal vs. Online Tools?
Online tools work well for casual research and initial price orientation, but a licensed appraisal is necessary in specific situations. Professional appraisals carry a median error rate of approximately 1.5%, compared to 2.4-4.2% for consumer AVMs, and lenders require them before funding any mortgage. In Nevada, a licensed residential appraisal typically costs between $300 and $500.
Use an online tool when you want a quick ballpark for any address, you are browsing neighborhoods and comparing general price levels, or you are tracking market trends over time. These tools are fast, free, and adequate for early-stage research.
Get a professional appraisal when you are finalizing a purchase offer on a high-value property, you suspect the list price is significantly above or below market, you are refinancing or applying for a home equity loan, or the property has unique features that algorithms consistently undervalue, such as custom construction, large acreage, or historic designation.
Las Vegas new construction presents a specific valuation challenge. Builders rarely discount list prices, but they offer incentive packages worth $20,000-$50,000 in upgrades or rate buydowns. Online AVMs often miss these incentives, making builder-community comps look artificially high compared to resale. A licensed appraiser familiar with this market will adjust accordingly.

How Has the Las Vegas Median Sale Price Changed Over Time?
Las Vegas home values rose sharply between 2021 and 2022, then corrected modestly before resuming growth through 2025. The metro median climbed from $380,000 in 2021 to a peak of $430,000 in 2022, dipped to $410,000 in 2023 as mortgage rates rose, then recovered to $445,000 in 2024 and approximately $455,000 in 2025 (Zillow Research, 2025).
This trajectory matters when you look up a property by address. An estimate generated in 2023 may understate current value by $40,000-$50,000. Always verify that any valuation tool is pulling from recent data, ideally sales from the past three to six months.

How Can You Use This Data as a Buyer or Seller?
Buyers and sellers use property value data differently, but both need accurate numbers before making financial commitments. The National Association of Realtors reports that 87% of recent buyers used an online tool at some point during their home search (nar.realtor, 2025), yet many rely on those estimates too heavily when writing or evaluating offers.
For buyers: Start with two or three online tools to establish a price range for any address you are evaluating. Then request a formal CMA from your agent once you are seriously considering a property. If the list price falls within 3-5% of the CMA range, you are in normal territory. A gap larger than that warrants deeper investigation or a negotiation strategy.
For sellers: Know your online AVM estimate before listing, because buyers will look it up. If Zillow or Redfin shows a figure significantly below your target price, plan to address this with your agent before going live. A well-documented CMA with strong recent comps can support your price even when automated tools lag behind actual market movement.
Use our closing cost calculator to factor purchase costs into your total budget.
Citation Capsule: The National Association of Realtors 2025 Home Buyers and Sellers Generational Trends report found that 87% of buyers used online resources during their home search, with property value tools cited among the most referenced. Despite this, buyers who also worked with an agent were significantly more likely to report satisfaction with their final purchase price.
FAQ
How accurate are online home value estimators?
Online estimators are moderately accurate for on-market homes and less reliable for off-market properties. Zillow’s Zestimate carries a median error rate of approximately 2.4% for listed homes, rising to 6-7% for homes not currently for sale (Zillow Research, 2025). Redfin and Realtor.com show similar patterns. Use these tools to establish a range, not a precise number.
How do I find the assessed value of a property by address in Las Vegas?
Visit the Clark County Assessor website and search by property address. The result shows the official assessed value, which the county uses to calculate annual property taxes. The assessed value is typically well below market value. Nevada law limits how quickly assessed values can rise year to year.
What is the difference between assessed value and market value?
Market value is the price a willing buyer and seller agree to in an arm’s length transaction. Assessed value is the county’s official valuation used strictly for property tax purposes, often set at 35% of taxable value in Nevada. The two numbers serve different functions and almost never match exactly.
How often does the Clark County Assessor update property values?
The Clark County Assessor reassesses property values annually, with new values typically applied each July 1 for the upcoming fiscal year. Nevada statute limits the annual increase in assessed value to a maximum of 3% for owner-occupied primary residences, which can cause assessed values to fall significantly behind rising market prices during strong appreciation cycles.
Should I get an appraisal before making an offer on a house?
A pre-offer appraisal is not standard practice, but it can be worthwhile on high-value or unusual properties. Most buyers instead rely on a comparable market analysis from their agent before writing an offer. Your lender will order a formal appraisal after the offer is accepted. In competitive markets, some buyers waive the appraisal contingency, which increases risk if the home appraises below the purchase price.
Conclusion
Finding property value by address in Las Vegas starts with free online tools and ends with verified data from the Clark County Assessor, recent comparable sales, and a professional appraisal when the stakes are high. The median Las Vegas home price of approximately $455,000 in 2025 reflects a market that has climbed steadily despite rate headwinds. No single tool gives you the complete picture.

Use at least two AVM tools, cross-reference with county records, and involve a licensed agent before committing to a purchase price or a listing strategy. The gap between a good estimate and a bad one can easily reach $20,000-$40,000 in this market. That is a gap worth closing.
