Contract help - wording for escape clause

[Kelsey Schiefelbein]

Hi all, I have a deal I’m currently writing up a contact for to wholesale to another investor. I believe in full disclosure, so seller is fully aware of my intentions and in agreement. However, I would like to have wording in the contract that specifically states we will either find another buyer or contract becomes null/void , allowing us to walk away from the property. I have it worded in the contract currently stating... “Purchaser will find an investor/buyer on or before (closing date) or this contract will become null and void” Any long time wholesalers out there who use this language or something better in their contracts? Let me know if any more verbiage or more specific verbiage is needed. Thank you!
