Can I accept offer contingent attorney review?

I received an offer today that expires this evening and would like to have a real estate attorney review the purchase agreement before signing. I live in Michigan which is not a state where the purchase agreement is automatically subject to attorney review. I am wondering if there is a way to have it written up so that I can sign but have time to have an attorney review that purchase agreement. Thank you

p.s. I feel like the evening deadline is short and probably arbitrary on the buyers part. Is this typical to have such a short acceptance window?
