If you do have to move because of a job, you would be safest (in my opinion, i am not giving legal advice or financial advice), i would sell that property to ensure that you did not just purchase with the goal of moving out early and taking advantage of lower rates and lower down payments for purchasing your home as a primary residence. 

It would actually be a net PROFIT given the huge increase to tax revenues. 

For context, before I learned about his 6 unit I was planning to purchase a 2-3 unit long term rental in Q1 2025 as my first of many deals with a 5 year goal of financial freedom so I can coach my daughter's high school cross country and track teams.

If you have access to some money you can increase your equity in one jump.
