I recently found an off the market home that is for sale; it is in good condition and I am tempted to make the move but I don't want to make an impulsive decision.

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 1article 2article 3Does anyone have any insights about going about renegotiating the purchase price a few days before closing?

They can tell you what to look out for and inspect the system to determine the condition. 

Based on the data, it doesn't appear that we have the same market conditions.

When I went into contract the numbers worked, but given the market conditions I'm expecting to see a decline in home prices fairly soon.

However, The property is in good condition.

Form CVA, 3/20)The following terms and conditions are hereby incorporated in and made a part of or, as applicable, an amendment to, thePurchase Agreement or n Other _____________________________________________________ dated _____________(the “Agreement”) on property known as _______________________________________________________ (“Property”)in which _______________________________________________________________________ is referred to as Buyerand ___________________________________________________________________________ is referred to as Seller.From time to time, events overtake the ability of the parties to a contract to allocate the risk of nonperformance.

Term and conditions link.... looks like you need a lawyer for that. 

Is the house in good condition and ready to rent? 

I included screenshots of all the terms and conditions of the loan.
