Here's one for people just starting out, some jobs require multiple of the same properties such as the nightclub so right before you do the job make sure you start building the same property then purchase the one from the job and you'll end up with 2 properties for the same amount of build time.
Donate first 5x minimum, then equip Vanderbilt 4x minimum, Then u clone Vanderbilt with envy for a last donation. I'm burning through my laundry money in my new emp.
Hmmm, not sure on your empire donation level, but he minimum I can donate is 1 million, way above my 3* Victoria's range. I get only 1 extra donation with her, maybe 2 if I donate once without Envy or 2nd with her. Maybe you can squeeze more if you have Viper and Lady Vice, but they are event lts, not easy to be obtained by beginners, anyway.
*Unless the job offers you more than 10 of an item. Then it is best to buy thrm outright.
Been a while since I've done it. By I think the price won't increase until the items finish building. So if the job offers you 10+ for X amount of dollars. Start building 10 then go back and buy the items. If you have enough. Then you get a bunch for the same price
Some war tips. If you have the achievement "defeat people 50 levels above you" an enforcer can get it by stimming the big players on your own team. Heavies can get it from planting traps on big players. Snipers can get it by lucky shot and I think marking big players(if you get lucky to find one)
Massmurder I use that item method all the time when a new job area is unlocked. Take a guess as to how many maybe needed and burn through that many jobs before letting the final 10 finish. This is really helpful on accounts that are not done with all of the job locations and you Know how many you need. Saves tons of game cash.
