I am saving money now. When I buy, I will buy in cash, and avoid interest. When I sell, I can either sell outright, or if the interest rate is high, owner finance, and take the high interest.
Equity is not very liquid. It's not safe. Any you may not be able to take it out if and when you need it. You can invest the money in a conservative fund with no loss of principle and after some years have enough money to pay off your loan and still have your initial investment. But that's another topic.
