In short...you wont.
In length, I'm assuming that you are relatively new to mafia wars and have the newer version of how to make money, which is the "rackets" method.
Up until 2 months ago, everyone had properties to develop to make money. Zynga then decided to try a new method (which is still at the moment in beta and only affects people that joined from that point). They have said that at a later date when they have everything in place, that there will be incentives for the older players to cash in their properties in exchange for rackets.
All this could still change, but at this moment in time, that's how it is.
if you don't have a property tab in Mafia Wars, you have the rackets tab. that's where you can get your money.
Under the property tab while in Italy
buy them. they are available in the properties tab or rackets tab.
It's under the profile tab between the Godfather tab and the My Mafia tab. Click Profile tab and then click the Achievements sub tab.
If there is, it will be next to the FIGHT tab.IF you just join, then there is no properties tab for you to buy properties in the first place. You will have RACKETS tab + Influences points instead.
Go to the properties tab on Mafia Wars and it is the very bottom one. If you are just starting off it will probably take a little while before you can buy one because they are the most expensive property.
On the home tab. look at right side. you will get the list
To start your own family and be the Godfather, go to the 'My Mafia' tab, and then click 'Families'. Click the 'Start Your Own Family' button, you will have the option of creating your own Family.
the only property that cannot be robbed is the Mafia Mike's.
Properties were removed from Mafia Wars for new players several months ago.Previously, it could be bought from the Properties tab which was where the Rackets tab is now.
It get's stolen when Don What'sHisFace beats the crap out of you in a fight!
They can be purchased for rubles from the Inventory tab in Moscow.
