Department of Real Estate Assessments FAQs

Fair market value is the price your property would sell for under normal market conditions.

When determining the fair market value of residential  properties, the assessor considers several factors: 

• The price a typical buyer would pay for the property in its current condition in a competitive and open market 
• The value that similar properties are selling for in a specified area 
• Estimated cost to replace the property with today’s materials and labor costs

Assessments are effective as of January 1 each year. 

The Virginia state code requires that the total assessed value be allocated between land and building when reported.

A private appraisal typically limits analysis to a single, specific property on a certain date, usually based on the recent sales of a few comparable properties. Also, a private appraisal may be made for a variety of purposes, such as for purchase or sale, mortgage financing, a home equity loan, an estate settlement, or income tax purposes.

For real estate assessments, the mass appraisal method is used which is “the systematic appraisal of groups of properties as of a given date using standardized procedures and statistical testing.” Real property in Arlington is assessed annually, using mass appraisal methods, with an effective date of January 1. The annual January 1 assessments must equalize market values among all properties. Since the County's appraisals depend on the reconciliation of all sales in a neighborhood within a 12-month period, an assessment represents a typical, or average value for a property in relation to other property values.

Assessments are based on typical values within neighborhoods for the type and condition of the property. While the sale price of a property will affect its assessment, the effect will be diluted by the mass appraisal method, which considers all sales within a neighborhood to determine assessed values. Also, the County uses a 12-month sales period that begins 16 months before the effective date of assessment (January 1). For example, for the 2025 assessments, the period is September 1, 2023, thru August 31, 2024. Because of this time lag, assessments of properties that have sold more recently may differ from sale prices if real estate markets are changing.

Normally, a property's assessment is based on sales activity in a defined neighborhood. The assessed value of a particular property depends on the sales of other properties in the nearby area. Assessments are not typically based on sales outside the defined neighborhoods. Assessments are not determined by ZIP codes or larger areas of the County as often reported in the press.

The January 1, 2025, assessment relied on sales within defined neighborhoods between September 1, 2023, and August 31, 2024. Sales occurring after the analysis period in each neighborhood are reviewed and tested against the statistical models used to test the accuracy of the assessment models and to identify where refinements are needed.

Lot sizes do affect assessed values. The total value will be higher for a larger lot, but the rate per square foot will diminish as the lot size increases. The County assesses residential land by the buildable site. For example, if zoning requires a 6,000-square-foot lot for a single-family home, a parcel that is 10,000 square feet is valued at less per square foot than a 6,000-square-foot parcel. It's the principle of diminishing return.

Refinance appraisals have a specific intended use—to derive market value to secure lending from a financial institution. The approach and scope of that work are not intended to value properties for real estate assessments. Because the intended use and scope of work are different and different approaches are used, it is generally not recommended to use refinance appraisals to contest your County assessment.

Land in Arlington is valued using the per-home site valuation method, which places most of the value on the home site itself. Each lot in Arlington is unique in size and physical attributes, but the existence of a home site is the driving factor of value. Each neighborhood in Arlington has a base land value, and adjustments are made for properties above and below the average lot size. Each year, the Department of Real Estate Assessments monitors and analyzes sales of properties that are either vacant, unimproved parcels of land or that have been purchased and the improvements demolished for new construction. Given each lot’s unique features, the department determines the average lot size for each neighborhood and sets a base rate using market data.

Arlington County is a densely populated urban area that is scarce on land, which makes all home sites valuable regardless of each lot’s features. Assessments do not factor in potential use, so land values are not based on what could be potentially built on the lot in the future but only on the current home site and improvements. All excess land, whether wooded, sloped, un-buildable or unused, must be valued Its value is reduced by adjusting the base value rate depending on the size of the lot when compared to the neighborhood’s average lot size.

Each year condo market sales are analyzed to determine if an adjustment is appropriate and what the adjustment should be to the total assessment. Virginia state code requires that the total assessed value be allocated between land and building. This means that the total property value is derived first and changes to the land and building allocations occur after. An analysis of land sales also is conducted to determine the appropriate land adjustment for each condo neighborhood.  Land analysis may suggest an increase, reduction or no change. If there is no change in total market value, the allocation of the value between the separate land and building is adjusted. In most cases, when condo land value increases, the building value will decrease, if there is no change in overall market value.

The Department of Real Estate Assessments does not determine the amount of taxes owed on a property. The assessor’s primary responsibility is to determine the fair market value of your property. Once the assessments are determined, the County Board adopts the tax rates which are applied to the property. The Arlington County Treasurer then bills and collects the real estate taxes.

The Calendar Year 2024 tax rate is $1.033 per $100 of assessed value. Commercial tax rate for properties such as office buildings, hotels, general commercial properties, have an additional tax rate of $.125 per $100 of assessed value.

The annual tax rate is adopted each April by the County Board.

The assessment is multiplied by the real estate tax rate, which is set by the County Board each year.

Tax rates in Arlington are expressed in dollars per $100 of assessed value. For example, a tax rate of $1.026 per $100 would result in a real estate tax of $4,104 on a property assessed at $400,000.

The below chart shows two different ways to calculate taxes based on the tax rate and the property assessment.

All properties in Arlington County, except those designated for operating railroads, interstate pipelines or public utilities, are assessed.

Real estate taxes are billed in two equal installments each year: June 15 and October 5.

If the due date falls on a Saturday, Sunday, or holiday, late payment penalties will not be assessed for payments made the following business day. Per the code of Virginia, taxpayers are responsible for knowing the due dates and ensuring timely payment. The Arlington County Treasurer collects real estate taxes.

The property assessment can be found on the County’s website. Enter the physical address or Real Property Code (RPC) of the property, then select View. The tax rate for your property will be listed under tax balances link, located in the left column.

The 2024 General Assembly of Virginia session added language to VA Code § 58.1-3330 which amended section B to include the following: 

“If the overall total assessed value of real property in the locality, excluding additional assessments due to new construction or improvements to real property, would result in an increase of one percent or more in the total real property tax levied in the locality, the notice shall set forth the tax rate that would levy the same amount of real estate tax as the previous year when multiplied by the new total assessed value of real estate, excluding additional assessments due to new construction or improvements to real property.” 

Due to this change to VA Code § 58.1-3330, Arlington County now provides a hypothetical tax rate on the assessment notice to show what the new tax rate would have to be for there to be no change to the overall tax levy from the previous year. The notice will also state how much all real property changed from the previous year to the current. All real property includes commercial and residential properties. The hypothetical rate is based on this all real property change calculation. 

Below is a link to VA Code § 58.1-3330 which provides further information regarding the requirements for assessment notices. 

§ 58.1-3330. Notice of change in assessment

Property owners may request that an appraiser review their assessment by filing an Application for Review. Applications must be delivered, postmarked, or filed online before midnight on March 3rd.  

An appraiser will contact the property owner and schedule an appointment. The appraiser will review the information on which the assessment is based, and information identified by the property owner. Property owners will be notified of the results by mail or email, depending on their preference. An owner who has not received the results by April 1 may wish to file an appeal with the Board of Equalization to preserve that option in case they are not satisfied with the departmental assessment review.

Property owners who are not satisfied with the departmental review of their assessment may appeal to the Board of Equalization by filing an Appeal from Real Estate Assessment. Appeal forms must be delivered, postmarked, or filed online before midnight on April 15. The Board of Equalization is appointed by the Arlington County Board and Circuit Court to hear objections to real estate assessments. While the departmental review should be a property owner’s first step, appeals may be made directly to the Board of Equalization without a formal Departmental review by the department.

No; however, County appraisers cannot address conditions for which they are not aware. An exterior inspection will provide some information about the property, but it will fall short of a complete review, and the outcome of the contested assessment may be affected by a lack of information.

When determining the fair market value of commercial properties, the assessor considers several factors: 

• The price a typical buyer would pay for the property in its current condition in a competitive and open market 
• The value that similar properties are selling for in a specified area 
• Estimated cost to replace the property with today’s materials and labor costs 
• How much it takes to operate and maintain the property 
• Potential rental earnings

If the property being valued has more than one commercial component (for example, an apartment component with a retail component), each component would be valued using the market data for their respective property types and any available operating history. That would determine an overall market value that represents all components of the property.

The Department of Real Estate Assessments analyzes market-rate and committed affordable multifamily projects separately. If an apartment building has both market units and committed affordable units, the department would value the different units based on their respective data, while also incorporating actual operating history at the property.

Property assessments can be found on the County’s website. Enter the physical address or Real Property Code (RPC) of the property, then select View. The tax rate for your property will be listed under tax balances link, located in the left column. 

Tax rates in Arlington are expressed in dollars, per $100 of assessed value. For example, a tax rate of $1.033 per $100 would result in a real estate tax of $413,200 on a multifamily property assessed at $40,000,000.

Commercial properties, such as office buildings, hotels, general commercial properties, have an additional tax rate of $.125/$100 of assessed value. 

If the properties are located in one of Arlington’s three Business Improvement Districts (BIDs) there is an additional BID commercial rate: 

Commercial BID rate (CY 2025) 

• Ballston BID: $.045/$100 
• National Landing: $.043/$100 
• Rosslyn BID: $.078/$100
