A due diligence period of time might be available in the purchase agreement, which is a time frame provided to a buyer to fully examine a property, often by hiring experts to inspect the property, perform tests, etc., so that a buyer may decide on how to proceed.
A buyer might also be afforded an opportunity to renegotiate the contract based off of their findings or possibly even to terminate within a specified time period, in order to not be considered in default of the contract. Due diligence allows a buyer to fully understand what they are buying.
