Quick Summary
Selling a $750,000 home in Fairfax County typically costs 7.5% to 9.5% of the sale price before the mortgage payoff, roughly $56,000 to $71,000. Commissions are the largest line, averaging about 5.46% nationally in 2026.

That is the full cost to sell a house in Fairfax County, and the tax line is the part sellers most often leave out.
What do real estate commissions cost Fairfax County sellers in 2026?
What do real estate commissions cost Fairfax County sellers in 2026? Commissions are the largest single cost of selling, bigger than taxes, title fees, and prep combined. 2026 industry data (Clever, citing HousingWire tracking) puts the national average total commission at about 5.46%, roughly 2.88% to the listing side and 2.82% to the buyer's side per Bankrate's May 2026 analysis. On a $750,000 sale, 5.46% is $40,950. Since the August 2024 NAR settlement, buyer-agent compensation is no longer advertised on the MLS, and buyers sign written agreements defining what their agent is paid. Sellers may still offer buyer-side compensation as a concession, and Clever found 73% of agents say sellers in their market are likely to cover it. Every line is negotiable, and in Fairfax County's market, with NVAR's August 2026 Bright MLS data showing a $750,000 median and 21 days on market, sellers who treat commission as strategy keep more equity.
What closing costs does a Fairfax County seller pay?
What closing costs does a Fairfax County seller pay? Beyond commissions, budget 1% to 3% of the sale price in seller-side closing costs: $7,500 to $22,500 on a $750,000 home. The usual lines are the settlement or closing fee, deed preparation, any concessions negotiated into the contract, courier and wire fees, and tax prorations. Virginia custom puts most title costs on the buyer, but the split is negotiable and your settlement agent's fee estimate will spell it out. Fairfax County property taxes are billed semiannually, due July 28 and December 5, at the FY2027 rate of $1.12 per $100 of assessed value, so the closing agent prorates taxes between you and the buyer on the settlement date. Most Fairfax sellers land around 1.5% to 2% in this bucket before any prep spending.
How much is Virginia transfer tax on a $750,000 sale?
How much is Virginia transfer tax on a $750,000 sale? Virginia taxes the seller three ways on the deed. The state grantor's tax is $0.50 for every $500 of consideration (Va. Code Sec. 58.1-802), which is $750 on a $750,000 sale. Two regional fees apply in Northern Virginia: the WMATA Capital Fee of $0.10 per $100 (Sec. 58.1-802.3), another $750, and the regional Congestion Relief Fee of $0.10 per $100 (Sec. 58.1-802.4), another $750. Total: $2,250, or 0.30% of the sale price. The grantor pays these unless the contract says otherwise. Recordation taxes sit on the buyer's side: $0.25 per $100 to the state plus Fairfax County's one-third local rate ($0.083 per $100), per the Fairfax Circuit Court's fee schedule effective July 1, 2026. Fairfax County's own deed of conveyance tax is $0.05 per $100 in the FY2026 adopted budget.
What does it cost to prep a Fairfax County home before listing?
What does it cost to prep a Fairfax County home before listing? Prep is the only cost you control completely, and it can pay for itself. Most Fairfax County sellers spend $2,000 to $10,000 on paint, landscaping, minor repairs, deep cleaning, and staging. The highest-return projects are unglamorous: a steel entry door, a new garage door, fresh paint, and manufactured stone veneer all return more than their cost nationally in the 2025 Cost vs. Value report, while major upscale kitchen remodels return roughly a third. See our breakdown of the highest-ROI repairs before selling in Northern Virginia. The rule: fix what photographs badly and what an inspector will flag, and skip the $40,000 project that adds $15,000 of value.
What this means for values
What this means for values: Fairfax County's August 2026 median of $750,000 (NVAR, Bright MLS) makes this the market center, not a hypothetical. At that price, a typical seller's walkthrough looks like this: $750,000 minus $40,950 in commissions at the 5.46% average, minus $2,250 in Virginia transfer fees, minus roughly $15,000 in closing costs and prep, leaves about $691,800 before the mortgage payoff. Your equity is whatever remains after the loan balance. Two implications follow. First, every $25,000 of additional sale price is worth roughly $22,800 after costs, so pricing it right the first time matters more than it feels like. Second, the cheapest way to raise your net is avoiding the price reduction, because a market with 21 median days on market punishes stale listings.
