You are on a great path and a good start.
Cover your risks.
Have good (read EBM or Terri Scheer) Landlord Insurance not cheap like AAMI.
2 year fix is not that good IMO. Essentially you are fixed in the very period it is low. In two years it could be going past 6.5% and then you are...
As someone from the 80s I say ignore that time.
Learn from it but ignore as the rules are changed.
Fix if you want security. But it means you cannot sell as easy.
Losing your job / income is the greatest risk by far.
