amended assignment contract?

[Dustin Roberts]

hey BP community, so I am working on getting my first deal under contract. I have a buyer interested and I have the seller interested in selling but she wants 60 to 90 days to close. and she wants to find a new place to live before closing. now we were offering to help her find a new place so that we could secure ourselves with the deal. my question is can I hold and a sign that contract for 60 to 90 days with a contingency that if she does not have a new place we can extend the sign the contract 60 - 90 more days? is there anything illegal about doing this?
