Two ways, on two very different timelines.
Rental income — distributed periodically during the holding period, based on your share of net rental after operating costs, management and maintenance. This is the income you see while you wait.
Capital appreciation — realised only when the property is sold at the end of the holding period. This is where most of the potential return usually sits, and it is entirely unrealised until the sale completes.
Neither is guaranteed. If the property sits vacant, rental distributions can be reduced or paused. If it sells for less than expected, you can receive back less than you invested.
