what documents would I need?

[Dushon Brackins]

So I have a property in mind for $16,000 that is forclosed. I have two all cash Buyers who are interested in the property. I'm asking for $24,000 for the property, when other home in the area are being sold for $35,000- $40,000. When I choose a buyer that can give me the best deal on the property I would like to do a double closing. would I need to have to buyer sign some type of contract first?
