After 100 years you (your grand children) will get a notice stating the lease is over. You would then have two options.The buyer will be the owner for 99 years after which the landowner can assert ownership of the land again. What is the difference between a regular registration and a 99 year lease registration? If the buyer wants to sell the house how does it work? However there is no option to renew after the 99 years. The leases terminate and revert to the Indians at point. Florida law does not require a landlord to rerent a premises. The landlord is entitled to sit back and do nothing and let each monthly rent accrue.
