Package deal help

[Dan White]

I have a seller willing to let me "bring a buyer to the table" on his 6 building package (3 4plex, 2 duplex, 1 Sfr). He is willing to give me 30-45 days inspection period to market the property. Seller does not want to use an Option contract...not familiar with them. My question is has anyone done a wholesale like this with a more standard contract and what clauses did you use to make everyone comfortable so you could market the properties and have control? Thank you! Dan
