Do I need to use another purchase agreement??

[Reginald S.]

Hello all! I have a quick question that I need a fast answer for. If a seller and myself both agree on a price change regarding a property that I already have under contract, do I need to have them sign a completely new purchase agreement? Or can we somehow edit and make use of the original one? FYI: The seller lives out of state.

Thanks in advance guys for your valuable time, experience, and expertise!
