Title companies have adapted to this with gap insurance but it still introduces yet another delay in getting the deal completely done.

Currently, due to coronavirus issue, we are self-isolated at home and the tax office is delaying the paperwork. 

Just be up front and get it done with a minimization to his inconvenience. 

WE've changed up things a bit to minimize all contact.   

You could also look at delayed financing.

Coronavirus has led to a lot of adjustments, one of them being residents wanting to delay work orders or vendors not wanting to take work orders due to social distancing.

As for the buy now or wait, as @Adam Tafel mentioned, the harm in waiting is you continue to pay rent currently, which is money out the door (meaning minimal in the grand scheme of things). 

Hopefully, we can treat each other like human beings and work through this with minimal trauma.

As long as I have put in the efforts to minimize the magnitude of my losses, I feel I'll be at a net gain no matter what simply because of knowledge received.

Due to corona, we are unable to do title work until courthouse opens so closing is being delayed.
