how do house flippers actually make money when all they do is 103

[Akram Mollah]

hi - i am a buy and hold investor but thinking about flipping. 

Flipping homes to me seems like a day job where I am always looking for the next deal and at the same time i never really get any money in my pocket because i am rolling over the gains? 

Am i missing something here? how do home flippers get money in there pocket without paying taxes?
