Then, renovate most of the Buildings availlable, which will increase your income. This is how you do it: First have the Thief Faction Ability unlocked (If you have the 'Fast Fingers' Achievement, you have unlocked it) which means that a hirable Thief Guild Group will pickpocket anyone who walks past them, earning you alot of money (Around 100-2000 a minute). In order to get this rediculous amount of money, I have found a way to 'farm' money.

If you bought the 4 of them, you can buy the last 14 in the regular Book Shop in Constantinople, and I think the money you need for them averages at around 100.000. There are 4 Books located at Cappadocia (The Island you visit in Chapter 7: Underworld) which costs exactly € 352,303,. They will cost a considerable amount of money though. I am assuming that this also works on the xbox 360 version but I cant confirm this' - You need to aquire a total of 25 Books in the game, which 7 of them can be found at any given time (They appear as the 'Books' Icon on the Map, and are called 'Nicolo Polo Books') and buy the remaining 18 Books in the Book Store.

UPDATE: This Guide was originally from the 360, but user 'AypLar' has commented that the Achievement will unlock on the Xbox One if you do this: 'For those playing on xbox one, once you have gotten all the books (the marco polo book quests and the bookstore books) just press start and quit your game and it should unlock during the loading screen to the main menu.
