Newbie Wholesale Question Regarding Contracts

[Sierra Murphy]

First off I'd like to introduce myself. My name is Sierra and I'm new to BP. For the past couple of weeks I've soaked up a bunch of information regarding wholesaling from various sources (including BP), but I'm still confused about purchase agreement contracts/assignment contracts. Where exactly are you supposed to get these contracts from? Do you get these contracts from online, title companies, or an attorney?

Thanks,
