Hi. I don't want to be pedantic, but you always make this mistake, and it just drives me nuts every time... " business men skimming money that isn't THEIRS using them to buy property"

"Their" indicates a person possessing something, as in "Their car was parked in the next street". "There" indicates a place, it's a bit like the opposite of "here", as in "put the blue shirts here, and the red shirts there"
