Palace keeps a record of every rent change that ever happened. This creates a handy report when looking to see if a property needs a rent change or when the last one was.
You have two options. One report will show every property and every rent change and the other report is found against a particular property and will only show the rent changes relevant to that property.
A full report which shows every property in Palace and every rent change - Click on Property Reports - Property - Rent Changes
A report just on a particular property and only shows the rent changes relevant to that property. - Right-click on the Property you require - go down to reports and click on Rent Changes.
