I understand the difference between titles held in Fideicomiso vs. a corporate entity, and the confusing “restricted zones” but, if I were speaking to investors unfamiliar with Mexico, how can I assure them their investments will be safe?

If I had held I would have eventually made around a quarter million instead of losing 100k+.

This way the tenants will be held responsible for any damages.
