Revise exit strategy for coming downtown

[Account Closed]

Recently, I saw more and more posts that, the BP investors plan to hold their positive cash flow properties until their 80’s years old etc. My original exit strategy is to sell all my properties once the market change direction. But my portfolio are in decent areas and have nice positive cash flows. Very passive good income. Maybe they are right... I did some research, found that some houses were sold at $55k in year 1975, it was sold at $950k in year 2010. If you google more houses sold price in year 1960’s, 1970’s and today prices, you will find many similar results. I will consider learning from them. Maybe I need to revise my game plan a little bit. Once the market direction is changed (not happen yet), sell a few properties instead of all properties, to have enough reserve to pass stress test of 30% to 50% rent reduce. Then hold it until 80’s years old or pass it to my kids before 80 years old. What are your exit strategy or your thoughts? Sell all? Sell a few? Sell none?
