The average cost to build a hotel depends on the size you plan to build. The land is generally charged by the acre and will vary depending on where you buy it, and so will the taxes. Construction costs can run anywhere from $750,000 million to over $25 million to build from the ground up, but the average is around $22 million. According to Hotel Tech Report (https://hoteltechreport.com/news/how-to-start-hotel-business), a 115-room hotel costs about $22 million to open, including utilities and stocking the rooms with necessities such as beds and lamps.
