How can the developer give the high returns to the partner.

Your question is valid. And the answer is quite simple:     There are various hotel products. Units & products for sale in the Hotel development are: Condos, rooms, Studios, 1 Bedroom units, 2 Bedroom units, Presidential suites,  Parking Slots, Retail spaces in the shopping arcade, Restaurants, Coffee Shops, Bars, Night Club, Discotheque, Convention Center, Meeting Hall, Banquet Rooms, Party rooms, Wedding Hall, Gym, Fitness Center, etc. These products like the condos are sold or leased to individual investors or professionals. Projected Sell out sales from all the products from a 300 rooms development is expected at over $40 Million. In the past we have added 1-2 new project every year. In future new projects may be added for completion from 2023 to 2025.  On each new additional project, the company value is likely to increase by $10 millions.  There is plenty of room to grow.  Projected profits is $10 -$15 Millions from each hotel project. For payment to Partner we have fixed this as $10 millions.- of which only 50% ($5 mil.) is paid to the partners.
