Effectively, the break costs get sucked up in the re-fi process at settlement. So your paying interest ont he new loan, which is for the purpose of investment, so that's all good.
I broke all of my fixed to 1) improve serviceability and 2) release huge chunks of equity for the next phase in my investment cycle.
It cost me around $20k overall, but the valuations I got ont he properties far exceeded my most ambitious expectations, so I ended up miles in front of my budget even after the break costs.
The bond market had taken a bit of a hit recently, which has impacted the reinvestment rate they use to calculate the break costs. That hurts a little.
I settled one on the 27th May. The break cost increased $1,000 since the estimate they gave me 10 days prior to that. Unlucky timing, but a small price to pay for $60k equity release.
