double close and tax delinquent

[Account Closed]

I have a question for the BiggerPockets family. When I have a property under contract and I am going to wholesale the property. When doing a double close can I use the same contract that i used with the seller or do I need to have a complete different contract style to fill out with my new buyer? And also when wholesaling property's with back taxes on them do I need to have a specific clause in the contract that allows me wot buy the home with back taxes on them so the taxes will get paid off at closing by the buyer. and back taxes will be included in purchase price.
