Fairfax County and Loudoun County sit next to each other in Northern Virginia, but a useful comparison starts with the exact home, tax district, and commute rather than a broad claim that one county is cheaper or better.
The counties publish different base real-property tax rates, but that does not make one exact home cheaper than another. Purchase price, assessment, financing, insurance, association fees, condition, and commute costs all affect the result.

Home prices and market pace
Compare current listings for similar property types, locations, lot sizes, and conditions. Then review the full monthly payment and property-specific comparable sales with an agent and lender. A countywide figure cannot tell you what a particular home is worth or what it will cost to own.
Property-tax rates
For tax year 2026, Fairfax County lists a base real-estate tax rate of $1.12 per $100 of assessed value. Check the Fairfax County real-estate tax-rate table for the applicable district and additional charges.
Loudoun County lists a 2026 real-property tax rate of $0.805 per $100 of assessed value. Check Loudoun County's 2026 property-tax rates for the property and district involved.
Assessment and sale price are not always the same. Verify the current assessment, district, exemptions, and additional levies for the exact property before relying on an estimate.
Commute planning
A countywide commute estimate hides too much. Travel time changes with the property's location, destination, departure time, toll-road choice, and transit access.
For a useful comparison:
- Test the two exact addresses at the same weekday departure time.
- Compare both driving and transit when either is realistic.
- Repeat the test for the return trip.
- Include tolls, parking, transfers, and first-mile travel.
Use the official WMATA Trip Planner for Metrorail and bus options and Virginia 511 for current road conditions. A home near a station or major route can have a different commute from another home in the same county.
School assignments
School assignments can change and are property-specific. smover does not rank neighborhoods or recommend a county based on schools.
Verify an address directly with the Fairfax County Public Schools Boundary Locator or the Loudoun County Public Schools attendance-zone maps. Confirm the assignment with the school division before making a housing decision.
