The Italian fiscal police, the Guardia di Finanza, have sent a questionnaire to 30.000 students who study at Rome's universities but come from outside Rome and rent accommodation in the city. The students are asked where they live in Rome, who owns the property, how much rent they pay and if they have a legally-registered renting contract. The information received is being checked against the various suppliers of services, gas and electricity, to see if the property is registered as unoccupied. When all the information has been gathered, property owners who are letting property illegally will be fined for tax evasion. Student accommodation in Rome is difficult to find and the average rent for a room in a shared flat or house is currently 300 per month plus expenses.
