Can I buy a pre-foreclosure?

[Brandon Handel]

So I'm wondering if it's possible to buy a pre-foreclosure. Some light reading online gave me mixed answers as to if you can legally do it anymore. I'm hoping someone on here has tried to do and can tell me if I can and how it works exactly. Can I just offer to pay off of their mortgage, and if the deal is good enough, offer to pay more to help them with moving expenses and such to get them out of the house faster? That way I get a great deal on a house and they get out from under it without having to foreclose and they get money to help them move elsewhere. What are your thoughts? TIA
