11 separate contracts or 1 contract for all

[Shequann Burrwell]

i have 11 indiana properties under contract recently. the seller was fine with signing 11 separate contracts for the 11, but yesterday the seller asked me if i could just use one contract for all 11. my only issue is if i do 1 contract for all 11 properties will i need to sell them all to one investor or can i sell them each separately with just one contract. if so how would i word the contract so that its not confusing for them to understand. they are from overseas and dont speak very good english.
