What Jonathan said makes the most sense, I would dig deep into every number stated and make sure you can verify everything with proof.  

John's gone off the deep end. 

What works is to buy low/@deep discount which is done in my world by marketing/prospecting/referrals.

We also have two mobile home parks and very few apartments units.Let’s step back, take a deep breath and calm down to make ration decisions.

The sellers may not care about what income you will be out of and at this point they may be more concerned with the fact that they have a binding contract with you and depending on their situation, may be relieved that they will be out of this property in 4 weeks. 

Agree with @Jay Hinrichs     I'll say this in my own way:  Deep discounts during the GFC occured because lots of properties went bank to the banks, combined with bank lending freezing up. 

Most are just not paying anything at all and not renegotiating since no one knows how long this will last or how deep this will get.

As a new investor, it's highly likely that your number 1 problem is a (completely legitimate) fear of failure--as would be the case when starting in any new business.You’ve done the researchYou’ve learned everything there is to know about real estateYou have a deep understanding of the marketplaceYet, you are still afraid to take action!

Complaining here is like Don Quixote fighting windmills: maybe it helps you relieve tension, but does little/nothing to enact change. 

How deep is the crawl space?
