Buyer has an Option Period, usually 7 to 10 days, to examine the property and conduct whatever other due diligence buyer deems appropriate. During this Option Period, the ball is entirely in the buyerâs court. If the buyer does not terminate prior to the end of the Option Period, the deal continues unchanged.
Most option periods are from 5- 10 days but can be as little as one day or as long as 30 days, some sellers base the option fee off of the length of the option period.
