South Riding's 2027 assessments were adopted in October. Starting in January, the South Riding Proprietary's townhome assessment rises to $122.40 a month, up from $110.80 this year. The association's own comparison, based on unrounded figures, puts the increase at $11.55. Any townhome buyer who closes after the new year will pay the new rate from their first statement. No other main home type in the community is getting a larger percentage increase. Over the same period, the Loudoun County townhome market has loosened faster than the detached market. That means buyers of attached homes have more room to push on price, and the cost they cannot negotiate is the one that is climbing.
Taken together, these two facts change what a good townhome offer looks like in South Riding this fall. The useful target is the total monthly cost of owning the home, and the purchase price is only one part of it.
The assessment that rises fastest is the townhome assessment
The South Riding Proprietary board adopted the 2027 operating budget and assessment schedule at its October 7 meeting. Here are the 2027 rates for the three main home types, using the association's own comparison with 2026:
| Home type | 2026 monthly | 2027 monthly | Change |
|---|---|---|---|
| Detached home | $101.95 | $110.30 | +8.16% |
| Detached home with common drive | $115.75 | $126.80 | +9.51% |
| Townhome | $110.80 | $122.40 | +10.42% |
The gap between a townhome and a standard detached home goes from $8.85 a month this year to $12.10 in 2027. In the association's breakdown, the townhome rate is made up of the same common and recreation charges every detached owner pays plus a $48.60 townhouse component.
According to the Proprietary's budget announcement, the extra revenue keeps current services in place and does not add new ones. The board applied $400,000 in surpluses from past years and $425,000 in interest income to keep the increase down. Reserve contributions for 2027 are budgeted at $1,853,900, up from $1,666,800 in 2026. The reserve accounts held $9,604,492.51 as of September 30, 2026. A well-funded reserve means future buyers are less likely to face a special assessment. It also means the monthly assessment carries a steady replacement cost, and that cost does not go away.
The association still describes its fees as among the lower monthly fees in the greater Northern Virginia region. That remains true. What changed for 2027 is the direction of the cost, and townhomes are moving fastest.
Why the price conversation has softened on the attached side
The county numbers explain where the negotiating room comes from. The most recent Loudoun breakdown by property type is the Dulles Area Association of Realtors' August 2026 Market Indicators Report, with data pulled September 15, 2026. It shows the two halves of the market moving apart:
| Loudoun County, August 2026 | Townhome & condo | Single-family detached |
|---|---|---|
| Active listings | 458, up 34.7% year over year | 389, up 12.1% |
| New listings | up 12.1% | down 4.1% |
| Average days on market | 27, up from 24 | 22, down from 24 |
| Average sold/ask ratio | 99.2% | 99.5% |
| Median sales price | $607,500 | $1,050,000 |
| Months of supply | 2.0 | 1.9 |
DAAR combines townhomes and condos in one category. Even with that limit, the pattern is clear. In August, attached listings grew almost three times as fast as detached listings, attached homes took longer to sell, and attached sellers kept a slightly smaller share of their asking price. On the detached side, new listings fell and homes sold faster than a year earlier.
September's countywide figures point the same way. The Northern Virginia Association of Realtors' September 2026 report shows Loudoun active listings up 34.1% to 1,031, average days on market up to 31, and closed sales down 17.8% to 338, while the median sold price edged up 0.8% to $758,500. NVAR's regional figures do not include Loudoun, but they show the same trend nearby: condo and townhome inventory grew for a third straight month while detached inventory rose just 5.7%.
The median price barely moved in either month. The leverage shows up in listing counts and time on market, and those are the measures that decide whether a seller takes a request for closing help seriously.
In 20152, there are more listings than last year, and buyers are still signing contracts
DAAR reports South Riding under ZIP 20152, which it labels Chantilly. These figures cover every property type in the ZIP, including detached homes, so they describe the whole local market and not only townhomes. In August 2026:
- New listings rose to 41 from 34, up 20.6%.
- Active listings rose to 49 from 37, up 32.4%.
- Months of supply rose to 1.8 from 1.5.
- Closed sales fell to 27 from 32, and the median sales price was $720,000, up 0.3%.
One figure runs against the county trend. Pending sales in 20152 rose 13% in August, to 26, while pending sales countywide fell 24.6%. Buyers in this ZIP kept signing contracts while much of the county slowed.
So the leverage is real, but it is limited. NVAR notes that 2.5 months of supply is still well below the five to six months usually associated with a balanced market. At 1.8 months, 20152 is further from balanced still. A townhome buyer here can reasonably ask for concessions. A buyer who assumes every seller is under pressure is likely to lose the well-priced homes to the buyers who are still writing offers.
A builder on Tall Cedars Parkway is selling the same kind of home
Resale townhome sellers in South Riding also face a competitor that the county numbers only partly capture. Toll Brothers is building Cedar Terrace behind the Home Depot, off Route 50 along Tall Cedars Parkway between Riding Center Drive and Pinebrook Road, as an extension of South Riding Market Square. The Loudoun County Board of Supervisors approved the project on February 14, 2024. The plan includes more than 220,000 square feet of commercial space, and the Proprietary's project timeline names Life Time as a future tenant.
Toll announced the community's opening on May 21, 2026, with townhome and condominium collections priced from the mid-$500,000s. It is selling two product lines:
- Towns Collection: townhomes from 1,776 to more than 2,300 square feet, three bedrooms and two-car garages.
- Lofts Collection: condos from 1,470 to 2,586 square feet, three bedrooms and one-car garages.
In late October, the builder's community page listed nine quick-move-in homes priced from $520,000 to $770,000, with move-in dates running from December 2026 to March 2027. That range sits right around the $607,500 county median for attached homes in August. A buyer touring South Riding resales this winter can tour a new build with a near-term delivery date a few minutes away.
The builder advertises its own future amenities, including an outdoor pool with a bath house, a tot lot and pocket parks. Toll's published materials do not state Cedar Terrace's monthly association fee, and they do not say whether owners also pay a South Riding Proprietary assessment. The Proprietary's condo listings name Amberlea, Lakeside and Town Center, each with its own SRP rate. A buyer comparing a resale townhome with a new one cannot compare monthly costs fairly without both figures in writing.
Turning the leverage into a lower monthly number
When attached inventory is up, homes are taking longer to sell and a new-construction alternative is nearby, the price is not the only term a South Riding townhome buyer can negotiate. These questions help turn the market conditions into an actual monthly figure:
- What will the assessment be on the first statement? For a closing after January 1, the townhome rate is $122.40 a month, so use that figure in the budget and not the 2026 rate shown in older documents.
- Does this home pay more than the base townhome rate? Detached homes with a common drive pay $126.80, and condo units pay the SRP rate plus whatever their own association charges, billed through their management companies.
- What does the new-build alternative cost each month, in full? For Cedar Terrace, get the association fees and any South Riding Proprietary obligation in writing from the builder before comparing it with a resale.
- What has this listing's time on market been compared with 27 days? That was the August average for Loudoun attached homes. A listing well past it gives the buyer more to work with on concessions.
- Would a seller credit do more for you than a price cut? In a market where sold/ask ratios have slipped below 100%, both are reasonable requests. Your lender can tell you which one lowers your monthly payment more.
A few direct questions
Are South Riding townhome prices falling? No. The August 2026 median for Loudoun townhomes and condos was $607,500, up 0.4% year over year, and the 20152 median for all home types was $720,000, up 0.3%. What changed is the number of listings and how long homes take to sell. That affects the terms buyers can get more than the sale price.
Does the higher assessment fund anything new? According to the Proprietary, it does not. The increase keeps current services in place and funds reserves at the levels recommended in the association's January 31, 2024 Replacement Reserve Study.
Is a detached home a better value now? The detached market is the tighter one. In August, its listings grew more slowly and its homes sold faster, so a detached buyer generally has less room to negotiate even though the monthly assessment is $12.10 lower.
