Rescinding an offer to lease a property

Is it permissible to rescind a lease offer after the offer has been verbally extended and the lease was sent to the prospect for signing? I extended a verbal approval and offer to rent my property on Thursday. The lease document was sent over to the prospective tenant via DocuSign on Friday am. The prospective tenant has several requests for accommodation and modifications to the lease. I accommodated some of the requests. I sent an updated lease DocuSign document yesterday am with the modifications. The tenant has more requests and some questions around the funds due (which is really straight forward). I would prefer to not lease to the individual as this has become quite laborious and potentially a sign of things to come. The DocuSign offer expires at the end of the day today. Regardless if they sign today I can always not sign myself. Any insight would be greatly appreciated as I haven't encountered this before. 

Thank you,
