Mamie Hanson converts her principal residence into a rental property. This property had cost $$850,000$ several years ago. It is converted on January $1,2023$ and, at that time, it is estimated that the total value of the property has increased to $$1,100,000.$ At this time the value of the land is unchanged at $$400,000$ with $$700,000$ attributable to the house. Provided her rental income before CCA is more than this amount, what is the maximum CCA that Mamie can claim for $2023?$
