Do I have to change my mortgage??

[Alex Waite]

I am planning on house hacking a condo and getting a mortgage to afford it. I plan on living in the condo for 1-2 years and then rent it out and buy another condo. Do I need to refinance or change my mortgage on my first condo since it is going from a primary to investment property? Or can I keep that same low primary resident interest rate? Any other tips about house hacking and the financing aspect would be appreciated. Thanks!!
