Renegotiate buying price after corona-virus

[Milind Shastri]

Has anyone renegotiated the purchase price of a property (being bought through a whole-seller)? 

The deal was entered before the COVID-19 situation, but considering the sudden change of market conditions, it now seems like there is good reason to believe that the house prices will go down, see a few articles: 
article 1
article 2
article 3

Does anyone have any insights about going about renegotiating the purchase price a few days before closing?

Thanks.
