Final answer:
In Oregon's agency disclosure statutes, exchanges of real property are included, while leases of commercial properties might be, depending on the lease term. Landscaping contracts and vehicle purchases are not covered as they relate to services and personal property.
Step-by-step explanation:
Under Oregon's agency disclosure statutes, transactions involving transfers of real property interest, such as exchanges of real property (a), are explicitly included. These statutes mandate that agents disclose their role and duties to the parties involved in such real estate transactions. Leases of commercial properties (b) may or may not fall under these statutes, contingent on factors like lease duration and state-specific regulations. However, landscaping contracts (c) and vehicle purchases (d) are generally not covered by real estate agency disclosure statutes.
This exclusion stems from the fact that landscaping contracts involve services, and vehicle purchases pertain to personal property rather than real property. Oregon's disclosure laws, thus, focus on transactions related to real estate to ensure transparency and accountability in real property transactions while distinguishing them from other contractual and personal property arrangements.
