I mean hopefully you have some reserves to cover slow or non-existent months.

As @Hai Loc mentioned 1031 doesn't exist in Canada.

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?

The positive that can come from businesses that survive is they discover other parts of their business for growth that they likely did not know existed or gave much attention to.

Property management is a hands-on business, especially when you take property showings to prospective renters, maintenance, and move-in / move-outs into account - all of which require face-to-face contact.Secondly, landlords and property managers alike have either already, or likely will face, issues with delayed or non-existent rent payments come April 1st.

Since then I have been working on increasing my self-confidence, establishing exceptional credit, eliminating my past debts and increasing my wealth by saving more of my existing income.

Your existing lender?

The government taking my product with no reimbursement doesn't happen in war time; private property rights still existed.

The demand will remain the same for residential rentals as our population is not changing and if anything is growing in spite of the struggles we are now facing.I still think commercial real estate can be a great investment in OKC but I think many folks get into it and are either over leveraged or have their numbers adjusted to work in a "normal" situation which we all know does not exist in our present setting.Again as always this is only my opinion and my views from seeing my small corner of the world here in OKC. 

Those landlords may not charge late fees or attorney fees to tenants while the COVID-19 emergency exists and may not file to evict for non-payment.
