Purchasing property on Banqer

I have just opened up the property module for my students, and I have some students who posed questions to me about the property module!1. Will their investment in a rental property earn them a profit in the long term?2. Can they pay back their mortgage at a faster rate than the 40% that is deducted from their rental income?3. Can they sell their property back to the bank?Basically, I think they want to know whether it is worthwhile buying a property. We have discussed the modules in real world terms, but they would like some more info about the virtual Banqer properties!Thanks!Kaii
