Summary answer: For a firm 2-year assignment, this is a closer call than most PCS buyers assume — buying can still make sense given Alexandria's single-family segment leading Northern Virginia in projected appreciation (4.2% for 2026) and the $0-down VA loan option, but the math depends 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.

The core math for a 2-year window
| Factor | Favors Buying | Favors Renting |
|---|---|---|
| Selling costs (typically 6–8% combined) | ✓ — a short hold makes these harder to recoup through appreciation alone | |
| Single-family appreciation trend (+4.2% projected, leading NOVA) | ✓ — 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 a 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 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 (Alexandria performs well for this), 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 remotely
- Limited savings 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
- Genuine uncertainty about extending or interest in keeping the property as a rental long-term
- Targeting single-family, which carries the strongest appreciation support in Alexandria right now
