house-hack roadblock - need advice

[Patrick Stewart]

My wife and I have considered a few options for expanding our real estate portfolio. We believe that house-hacking is our best bet. However, we refinanced our current primary residence 4 months ago. Our ideal scenario would be to buy a new house as our primary, live there, rehab, and then start renting it in a year. We'd also like to keep our current primary and rent it out. However, our current refi is a roadblock. 

Does anyone have a solution for getting around this? When we refi'd we had no intention of moving within a year (and renting it out). Do we really need to wait 8 more months if we want to rent our current primary residence?
