My tenant pays on time, reports maintenance issues early and looks after the property. They currently pay ZAR 50,310, while comparable market rent is around ZAR 57,110. I do not want that gap to keep widening, but vacancy, tenant replacement and deposit handling all carry cost and uncertainty, particularly with flood risk in the picture. Would you use small predictable increases, freeze the rent, or pair improvements with a later review? What detail would decide it for you?
