Supreme Court decisions treat renewal options as personal promises rather than rights that bind a future owner, so the second and third 30-year terms are not automatically enforceable. For real security, layer instruments: register the lease, add a usufruct (sitthi-kep-kin) and a superficies right over the structure.

Yes. Register a superficies right (sitthi-nuea-phuen-din) at the Land Office and you own the building separately from the land. The right can be sold, mortgaged or inherited within its term, which is why long-term expat houses on leased plots are usually structured this way.

No. Section 540 of the Civil and Commercial Code caps a residential lease at 30 years. A marketed "90-year lease" means one registered 30-year term plus two contractual renewal promises, each of which must be re-registered at the Land Office when the previous term expires.
