Each faction building in Rome belonged to either the courtesans, mercenaries, or thieves. Ezio could renovate a faction building for 1,200 florins, after which the members of the faction he assigned it to could be found outside. They would then assist Ezio after having received a payment. The faction buildings also generated income for Ezio, which could be collected from banks. Ezio could reassign a building to another faction if he desired, although he had to pay 900 florins to do so.
