This achievement can be combined with "Doing Good".
You get a penalty for shooting your teammates, killing a civilian or when you reach the getaway vehicle first and cut 50/50 with the pilot. Do not do any of these things.
An easy way to do this is to pick the Airport level. Now from the start, run down the right hand side until you get to the wall and baggage cars with a few Police behind it. Behind this, is an opening which leads to the side of the building where the money is. There is a stair case going up the side of the building. Simply run up the stairs and kick in the door. Run to the left and kick the bridge over. There will be 2 guys in front of you, so kill them and in the middle of the walkway, turn right and go up the stairs to the roof and escape. Repeat 4 more times without shooting your teammates or killing any civilians (which there are none if you follow this route).
Once the initial 5 runs are out of the way, repeat 5 more times to unlock "Love of Money".
