Final answer:
The sales contract entered into by an intoxicated individual would generally be classified as voidable since the intoxicated party's capacity to consent is impaired, but it remains valid until they choose to void it.
Step-by-step explanation:
When an intoxicated individual enters into a sales contract to purchase a home, the contract would generally be considered voidable. This is because, at the time of entering the contract, the individual's capacity to understand the nature and consequences of the agreement is impaired. Thus, they lack the legal capacity to enter into a binding contract.
A voidable contract is valid and binding until the affected party (the intoxicated individual, in this case) takes steps to void it. If the individual becomes sober and decides to affirm the contract, it remains valid. If they choose to void the contract upon regaining sobriety, provided they do so in a timely manner, the contract can be nullified.
