In any investments, exit strategy is to set profit from the return collected from what you put in.
As your property gets older, there are more risks that you need to consider. Even though it is generating high return now, it is not promised that cash flow goes negative in the future.
So selling your property at the right time and setting the final profit would make it possible to reinvest in other real estate properties to build up your assets.
The basic of an exit strategy is to sell properties. However there are other ways to it which would be tearing down the property and rebuild and not selling the property and hold it for long.
It’s best to think about your exit strategy when you purchase the property.
You need to plan the cash flow simulation with a long term vision when you start investment.
