The main purpose of this legislation is to encourage the sale of certain real estate interests that are acquired through a specific program aimed at balancing military readiness with environmental protection. It does this by allowing sellers to exclude any profits from these sales when calculating their taxable income. Key provisions of the law include the definition of what qualifies as a "qualified real property interest." This can be the full ownership of a property, a partial interest, or a restriction on how the property can be used.
