Leasehold agreements remain the primary option for foreigners seeking land or houses in Thailand. Standard contracts provide 30-year terms, with renewal conditions varying by agreement. The lease must be registered at the local Land Office for legal validity. Critical factors include transferability rights, maintenance responsibilities, and potential rent adjustments. Some developers offer structured 90-year leases (30+30+30), though only the initial term is legally binding. Leasehold properties typically depreciate as the term shortens, affecting resale value. Due diligence should verify the lessor's ownership status and any existing encumbrances. Professional legal review is strongly advised before signing.
