Sell primary to pay off investment property?

[David Wild]

Im considering selling my primary residence to pay off 3 rentals. I would be able to rent a house for the amount of rental income I would receive if they were paid for. This would allow us to use all our day job income to completely pay off a 4th rental within 2 years. Then the plan would be to save money for a down payment on a new primary residence  the following 2 years. At that point we would have about 5k in passive income to make our mortgage payment. If the market started to go crazy I would probably  sell the 4th property and buy a primary  residence sooner. Looking for pros and cons. Thank you.
