Best imagination:
It used to be a small motel. Four to five rooms. Before crossing the country's boarder, men of trade would stop in for the nights rest. Possibly built and owned by a entrepreneur man. The window room was his. This way he can see anyone coming or leaving the city. The other rooms were only large enough to hold a bed. This was all that was needed. Oh, but a small pot at the end of the bed for evacuation. When the man started his business out, he could not afford beds for the rooms. As time went by, first one for him, then one by one for the other rooms as time and business moved forward. Most tradesmen traveled by twos' or fours'.
From the earliest age, Rahab knew she could obtain money with trade. Her family gave up watching over her because of poverty. Tradesman would come into town, find her, and have their way with her. Word had gotten around. Monetary trade was always conducted however small. Family had their own problems to worry about anyone else.
The man that built the hotel heard about Rahab. Gave her a job, a room. This was on the opposite side of town away from family so she would have a little more privacy. Her job was to clean the rooms and provide service if need be.
Opportunity came when the man either died or went on a trip and never came back. Rahab was in charge now. She would operate the business as hers. The people around didn't become outspoken. They didn't ask any questions. The thought was some kind of deal was made and the property was now hers, but they knew what the business was all about. Plus people had their own lives to worry about. The business operated at night, and the days was her's to live.
...She escaped from the slavery of her youth.
