Question on Refinancing a Duplex

[Chaits J.]

Hello All,

I am in the process of buying a Single Family home off market which has a mother in law suite with a separate entrance that allows us to rent the home as 2 units once purchase & rehab is done. This will be my first BRRRR deal so trying to be prepared fore refinance phase in advance. When time comes for refinace, will this be considered as a multi family or single family home? ( Township has it zoned as Single family home).

Thanks all in advance.
