The common plan for the PCS problem is to rent the house out. That can work, and many military families build real wealth this way. It also converts you into a long-distance landlord managing a property from another time zone.
Run those numbers cold: mortgage, taxes, insurance, property management fees, maintenance reserve, and realistic vacancy. If it only works with zero vacancy and no repairs, it does not work. It also changes your tax situation and your ability to use the benefit for the next house.
- Full monthly cost including taxes, insurance, and HOA
- Realistic local rent, not the optimistic figure
- Property management fees if you will not self-manage
- Maintenance reserve and expected vacancy
- Effect on your remaining entitlement for the next purchase
