There is a case of a family who was in the process of contracting a townhouse in Centreville. They found a property they liked and completed the offer and contract in just two months, but just before closing, they received HOA documents that included plans for special assessments for roof and exterior wall repairs. Because they only checked the monthly management fee before signing the contract, they ended up with unexpected costs starting in their first year of residency.

The median home value in Centreville is around $631,224, which is a 2.4% increase from a year ago (as of 2026, according to the Zillow Home Value Index). In the broader Fairfax County area, the median sales price for the first half of 2026 is $780,000, up 2% from $765,000 a year ago, and as of June, the median sales price has risen to $810,000 (according to the Northern Virginia Association of Realtors, Bright MLS). While the numbers suggest a gradual trend, actual listings often stay on the market for only 24 to 35 days, which aligns closely with the real market experience.

In such a fast-paced market, it is common for buyers to only calculate the mortgage principal and interest when budgeting, neglecting property taxes, homeowners insurance, HOA fees, and maintenance costs (CFPB Homebuying Guide). In areas like Centreville, where townhouses and condos are prevalent, communities often require HOA membership, and it is essential to check not only the management fees but also the reserve fund status and any planned special assessments to accurately gauge total ownership costs. Virginia sets property tax rates separately by county and city, with the statewide average effective tax rate reported to be around 0.671% (as of 2026, according to WorldPopulationReview). The actual tax rate in Fairfax County may differ, so it is advisable to check with the county tax office for the exact rate for a specific address.

In a market where properties are sold within a month, buyers often visit listings without mortgage pre-approval, only to find that their paperwork is not ready when it comes time to make an offer, causing them to miss competitive opportunities (CFPB, NAR data). In a seller's market, it is not uncommon for offers to forego inspection contingencies, and the NAR's survey of first-time homebuyers consistently shows cases where buyers skipped inspections due to competition, leading to unexpected repair costs for plumbing or roofing after moving in.

Closing costs are another item that can be easily overlooked. They are typically reported to be between 2% and 5% of the sale price (according to the Bankrate Closing Cost Guide), meaning that for an $810,000 property, an additional $16,000 to $40,000 may be needed at closing. If buyers do not account for this amount while preparing their down payment, they may find themselves short on funds at the last minute.

Families moving to Centreville from other states may overlook certain aspects based on their previous tax systems. If they are coming from a state with relatively low property taxes, they might find Virginia's rates to be low, but it is more accurate to compare total ownership costs, including insurance and HOA fees. If prioritizing school districts favored by Korean families, it is advisable to refer to metrics like GreatSchools or Niche, but since school district boundaries change frequently, it is important to verify the assigned school for the specific address before purchasing.

Another common mistake is exhausting all reserves for the down payment. Even in a consistently in-demand area like Centreville, unexpected expenses can arise shortly after moving in, such as for a boiler or roof. Instead of maximizing the down payment, it is safer to leave reserves equivalent to three to four months of living expenses after closing. It is also wise to maintain vigilance over credit scores and debt-to-income ratios until the contract is finalized. Large expenditures, such as purchasing a car or putting furniture on a credit card, can negatively impact loan conditions if they occur between the contract and closing (according to CFPB guidance). Lastly, some buyers make emotional decisions without thoroughly considering long-term residency plans, commute distances, and future resale potential. Since many families moving to Centreville consider both commuting conditions and school districts, the type of property that is suitable may vary depending on whether they plan to stay for more than five years or if they might move again within a few years.
