@Steve Burt -If an MLO was involved, as @Chris Seveney mentioned there will be a loan origination application and supporting paperwork to review.

I can cover the mortgage with my W-2 job and all expenses at this point in time(I am in an essential business).

Murphy advising that construction is no longer considered an essential business, I can't think of a way of finding out exactly how many units this will be or the exact type of apartments they will be. 

I am tossing around the idea of purchasing a single family home and renting out a fully equipped basement, essentially as a "duplex."

You need to go back and retrace your steps: they didn't send you requested paperwork "in time".

Are they Essential workers, do they work from home, etc.

Closing a seller on a lease option and selling the paperwork to a tenant buyer for 3 - 5% is WAY easier."

Problem is that I don't know what kind of paperwork, where to get the paperwork, etc.

Some states deemed RE Pros as essential, some did not - so depending on your hunting grounds it might be a little quiet for a while.

My essential point was when you are dealing with a conveyance with no warranties, which we are here as well as in the non-judicial (or quasi) foreclosure framework, that requires you to do your due diligence up front... all of it... and also to factor the unknown into your bid.
