In the renting of premises for purposes of prostitution various devices are employed to protect agent and owner, despite the fact that there is an overwhelming probability that in most cases both possess from the outset guilty knowledge of the facts. In some places, direct responsibility is avoided through renting empty apartments to janitors for a rental ranging from $40 to $50 a month. The janitor furnishes these apartments on the instalment plan and sublets them to prostitutes at the rate of $15 to $18 per week. Then, in addition, he often receives from $3 to $5 per week to "look away," as he terms it. If the respectable families do not like it, they may move; and many of them do move. The method of subletting furnished apartments by the janitor, with the consent of the agent (who probably shares in the extra profits) is employed in a tenement building on West 109th Street. In other places, the agents rent apartments by the week, demanding payment in advance. After a day or two, they may inform the occupants that a complaint has been made and that they will have to move. They do not return any of the advanced rental, but proceed to repeat the performance. This has happened in connection with furnished apartments on such streets as West 107th and West 108th. During the month of February, 1912, a woman investigator visited 122 real estate agents for the alleged purpose of renting an apartment for immoral purposes. In each case the investigator endeavored to convey to the agent the object for which the apartment was ostensibly desired. Of the 122 agents visited, only 17 refused outright to be parties to the transaction. A few of these were indignant, others said they had to be careful, and still others said the owners of the property were exceedingly strict. Sixty-seven agents agreed to rent certain apartments for this purpose and gave the investigator the addresses of 98 separate apartments where she could conduct the proposed business. Many of these addresses proved to be places where the present investigation had already discovered disorderly conditions. The remaining 38 agents were classified as doubtful. Some of them were annoyed because the investigator openly hinted her purpose; they suggested that they did not care, but would not knowingly rent the property in their charge for such a business. Others pretended to ignore the questions of the investigator and gave her 65 separate addresses where apartments could be rented. They were willing to rent apartments of this character, but did not want to appear to do so. A young man in a real estate office on Eighth Avenue stated that they "never ask people for their marriage certificates; they require only that tenants conduct themselves quietly." One well-known agent[192] betrayed and indeed confessed embarrassment when frankly told the purpose for which it was desired to rent a house. He remarked: "I know what you wanted the house for, but I had much rather you had not told me.
