The document discusses the regulatory challenges of marketing and selling Mexican real estate in the United States. It outlines that the Interstate Land Sales Full Disclosure Act (ILSA) requires projects to register with HUD and provide buyers with a property report, but exemptions exist for improved parcels completed within two years and projects with less than 100 lots. Non-compliance allows buyers rescission rights. Additionally, several states like New York and Arizona require projects targeting their residents to register at the state level. Websites marketing to US residents can constitute offers subjecting sellers to state jurisdiction. Consultation with legal experts is recommended.
