Nobody selling you something is the right person to answer this question. The honest answer is "it depends on four variables", and for a lot of PCS situations, the correct answer is rent.
The calculator above runs the math for your base. The four variables below are what it's measuring, and what to think through before you trust any number.
Variable 1: Time on station
Buying has fixed entry/exit costs, closing costs, funding fee, and one day ~6–8% to sell (commissions + concessions). You need time for appreciation and principal paydown to outrun those costs.
- Under 2 years: rent, almost always.
- 2–3 years:coin flip. Buying only pencils if you'd happily hold it as a rental afterward (see Variable 4).
- 3+ years, or homesteading (back-to-back tours, retirement location): buying gets genuinely attractive.
Variable 2: Payment vs. BAH
Full payment (principal, interest, taxes, insurance, HOA) at or under your BAH is the classic screen. Two additions: leave margin for maintenance (~1%/yr of home value; renters pay $0), and remember BAH resets at your next PCS. The payment must eventually work against rent, not your allowance, if you keep the house.
Variable 3: The local market's rent-vs-own gap
In some base markets a mortgage runs close to rent for the same house; in high-cost coastal markets owning can cost dramatically more per month. Compare actual listings both ways before assuming. Where the monthly gap is small and you have 3+ years, buying usually wins; where it's wide, renting plus investing the difference is a legitimate wealth strategy, not a consolation prize.
Variable 4: Your exit plan (the one people skip)
You will PCS again. On day one, know which exit you're buying:
- Sell at PCS: you need enough equity to clear the ~6–8% exit cost. Thin at 2 years on a zero-down loan.
- Keep as a rental:does market rent cover PITI + management (~10% if remote) + maintenance? If it only works with zero vacancies, it doesn't work. Done right, this is how military families build a portfolio, one PCS at a time. Done accidentally, it's a monthly loss you manage from three time zones away.
- No plan:that's a plan to get squeezed. Pick one of the two above before you offer.
Honest shortcuts
- Dual-military or very stable orders → buying skews stronger.
- First term, might separate, uncertain follow-on → rent, keep options.
- OCONUS or high-turbulence assignment cycles → rent unless homesteading is realistic.
- Buying because everyone in your unit did is not a variable.
If the framework says buy, the next move is a lender pre-approval and an agent who writes VA offers weekly. That combination is what makes a PCS-timeline purchase smooth instead of stressful.
