Given the existing unique situation of the COVID19 outbreak in NJ and under the state order of stay at home which requests us to stay at home at all time and keeps the travel to minimal unless absolutely necessary, how could I show the house to potential tenants?

Any information or ideas for minimizing  the impact of the pandemic will be appreciated. 

You are just wasting peoples time in that case.

You are being hurt by it, but that’s not very important in the grand scheme of things.And your knowledge of history around the issue of property rights is minimal.

So they are minimizing the risk considerably.

You want to minimize your capital output, to keep in reserves for the repairs and to weather the coming storm (it's what we're doing with our current deals we are pursuing.)

Numerous regulatory violations dating from a long time ago (ie mishandling hazardous waste materials) as the site has always been used for auto services since the 60's.Anyways, I guess the main question on what's the worst that could happen and how much will it cost to fix it would need to be answered by an engineer. 

As an professional you have too much to risk to waste time on this strategy, and I would recommend planning for 20-25% down on all investment properties.

If you fix it up, rent it for 5 years, and then sell it you will need to pay capital gains on the difference between your purchase price and what it sells for (there are strategies to minimize or delay the payment -- you can look into 1031 exchanges).- You talk a lot about equity.

Or you could let them pay what they can, break the lease early with a minimal penalty and get a new tenant in the door who's not affected by this crisis.
