What's reported may not be accurate for several reasons.
1. Maintenance fees generally go up every year. The seller may have started the sales process providing the MFs before they went up for the current year.
2. Some people post the MFs without the Program Fees, while others include the MF.
3. Even when including the program fees, the seller may have had other contracts/enough points so they were just paying the per point rate, and the buyer may not meaning that they are paying the minimum program fee. ($147 minimum vs .055 per point after reaching minimum)
