What happens to the rent of properties held by specific descendants as long as they remain in their original line?

The rent of properties held by specific descendants in their original line remains unchanged according to relevant regulations or agreements. This provision is designed to provide stability and security for family members who inherit property, ensuring that they are not burdened by fluctuating rents. This continuity can also help maintain the property within the family and allow descendants to use the property without the fear of sudden financial strain from increased rental costs.

The other options suggest a dynamic approach to rent that does not align with the principle of stability intended in this context. For instance, annual increases or periodic negotiations would imply a variable rent which could challenge the purpose of consistent affordability for the descendants. Similarly, a five-year review could also introduce uncertainty and potential financial burden, which is contrary to the original intention of keeping the rent stable. By providing a fixed rent, the goal is to preserve the familial connection to the property and ensure its accessibility to future generations.
