Summary answer: For a firm 2-year assignment, this is a genuinely closer call in Ashburn than in a lower-priced market — the $800,000+ typical price means transaction costs (typically 6-8% combined, $48,000-$64,000+) are a real dollar amount to recoup, though Ashburn's genuine market tightness suggests less price-decline risk than in a softer market.

I'm Johnny with JQ Real Estate. Let me walk through the actual trade-offs.

The core math for a 2-year window

Factor Favors Buying Favors Renting
Selling costs (typically 6-8% combined)   ✓ — $48,000-$64,000+ on a typical Ashburn home, hard to recoup in 2 years
Genuine market tightness ✓ — reduces the risk of having to sell into a soft market later  
$0 down VA financing ✓ — removes the capital lockup that makes short-term ownership riskier elsewhere  
Loudoun's low tax rate ✓ — reduces your monthly carrying cost regardless of hold length  

Why Ashburn's tightness is a genuine mitigating factor

Unlike a market with real price-decline risk, Ashburn's tight inventory (just 119 active listings recently) suggests you're less likely to be forced to sell into a weak market in 2 years — a real, if partial, offset to the transaction-cost concern.

What tips the decision toward renting

  • Certainty that you're leaving the area entirely after this assignment
  • Discomfort with the upfront transaction cost math

What tips it toward buying

  • A VA loan available, removing the down payment barrier
  • Openness to keeping the property as a rental afterward, given Ashburn's strong rental demand
