The community sets pricing and approval, and we confirm both before you sign. ### Should I include a gift card in the Special Decoder? No. Gift cards aren't rent, so we leave them out of net effective and true monthly. Enter only rent credits. ### Where do the BAH figures come from? MHA TX285, DTMO 2026 rates for E-5 and E-7. Other grades are pending verification. BAH follows the duty station; confirm your rate with your finance office. ### Can you guarantee a price or approval? No. The community sets both pricing and approval. We pull prices every morning and confirm the numbers with the leasing office before you sign. Still have a question?
