What is the economic ability of the owner of a self-operated hotel?

At present, the average market return period of mid-range hotels is 4 years. Hotel revenue = location * decoration * operation, which are the three most important factors that determine hotel revenue. However, 50% of the hotel's monthly cost is determined by the rent and manpower. During the hotel stay in property leasing, the monthly rent of the hotel shall not exceed 30% of the total monthly income, and the manpower shall not exceed 20%. If the two total costs account for more than 50%, the profit margin of hotel space will be small.
