Equity % and wholesaling

[Tyler Hall]

Hey everybody, aspiring wholesaler here. Today I am wondering what a sellers equity % in his/her property will have to do with the wholesaling process. If they only have 50 % equity in their home and I tie it up under contract will i be responsible for paying off the rest of the property? I honestly don't know if that even makes sense I'm clueless and can't find anything on the internet talking about this specifically. Maybe someone can help me understand the concept of equity in the wholesaling process  more. Thanks so much.
