The pdf would be accessible anytime. It's free to read the state of a smart contract anytime. In the event of default, the pdf would be automatically executed and delivered to the parties. I'm not familiar with the notary requirements for a deed, but there are plenty of online notaries (you submit a picture of yourself and your ID). Also doesn't Opendoor already process deeds completely online?
