Summary answer: For a firm 2-year assignment, this is genuinely a closer call than most PCS buyers assume — buying can still make sense given Arlington's structural appreciation in the single-family segment and the $0-down VA loan option, but the math depends heavily on selling costs, how much the property appreciates in that window, and whether you'd rent it out afterward rather than sell. If there's real uncertainty about extending or a follow-on assignment nearby, buying often wins more clearly.

I'm Johnny with JQ Real Estate. Let me walk through the actual trade-offs rather than a blanket answer.

The core math for a 2-year window

Factor Favors Buying Favors Renting
Selling costs (typically 6–8% of sale price combined)   ✓ — a short hold makes these costs harder to recoup through appreciation alone
Single-family appreciation trend (+3.8% projected) ✓ — meaningful equity growth possible even in 2 years  
$0 down VA financing ✓ — removes the capital lockup that makes short-term ownership riskier elsewhere  
Uncertainty about extending or follow-on DC-area assignment ✓ — reduces the risk of a forced short-term sale  
Certainty you're leaving the area entirely in 2 years   ✓ — cleaner exit without the risk of selling into a down market

Why the plan for year 3 matters as much as year 1

This decision isn't really "buy vs. rent for 2 years" — it's "buy and sell in 2 years, buy and rent out afterward, or rent the whole time." If you're open to keeping the property as a rental after your assignment ends (see how that works for Arlington specifically), the 2-year buying math gets considerably more favorable, since you're not forced to sell into whatever the market looks like at that exact moment.

What tips the decision toward renting instead

  • Certainty that you're leaving the DC area entirely after this assignment, with no interest in holding a rental property remotely
  • Limited savings for a down payment or closing costs beyond a $0-down VA loan's minimal upfront cash need
  • A strong preference for flexibility and zero maintenance responsibility during the assignment

What tips it toward buying

  • A VA loan available, removing the down payment barrier that usually makes short-term ownership riskier
  • Genuine uncertainty about extending, follow-on orders nearby, or interest in keeping the property as a rental long-term
  • A target property type (single-family) with strong structural appreciation support in Arlington
