If you delay the sale of your former residence unit until it has been more than 3 years since you vacated, your former primary residence becomes an investment rental and you no longer qualify for the §121 capital gains exclusion on the sale of a primary resdence.You can use a 1031 exchange to defer capital gains taxes on the sale of the investment rental unit since you are planning to use some of the sale proceeds to invest in another rental.
