Summary answer: Lorton falls under Fairfax County's standard real estate tax rate of $1.1225 per $100 of assessed value. On a $650,000 home (near several recent median readings), that's roughly $7,296 per year, or about $608 per month.
I'm Johnny with JQ Real Estate. Here's exactly how this breaks down.
What this rate means at different Lorton price points
| Home Value | Estimated Annual Tax |
|---|---|
| $450,000 (townhome/condo segment) | ~$5,051 |
| $650,000 (typical median range) | ~$7,296 |
| $872,000 (upper-tier reading) | ~$9,789 |
Why Lorton's genuine price variance affects your budget planning
Given the wide swing across recent readings ($557,000-$872,000), your annual tax bill genuinely depends on which specific property and neighborhood you target — always confirm the current assessed value for a specific listing rather than assuming the countywide median applies.
A note on land-heavy Lorton properties
Some Lorton listings sit on larger wooded lots, particularly near Occoquan or the Potomac riverfront — these can carry meaningfully higher assessed values than a comparable home on a standard suburban lot, worth checking specifically for your target property.
What to bring to your lender conversation
Come prepared with your last two years of tax returns, recent pay stubs, and a list of any other debts or assets — the more complete your picture upfront, the faster and more accurate your pre-approval will be. Lorton's genuine mix of townhomes, condos, and single-family homes on varied lot sizes means your lender should also know which property type you're targeting, since this can affect loan program eligibility and appraisal requirements.
How reassessments affect your bill
Fairfax County reassesses property values every year, so your bill can change even when the rate stays the same. After a year of softer Lorton prices, it's worth reviewing your assessment notice and filing an appeal if it runs well above what comparable homes actually sold for.
Factor this into your real budget

One more thing worth mentioning: rate shopping across at least two or three lenders genuinely pays off, even a quarter-point difference adds up meaningfully over a 30-year loan term.
