Converting Single family to duplex

[Yoni Meth]

Hey All,

I'm considering buying a SFH that was originally a duplex where the dividing wall was removed.

The house will need some renovation (paint, flooring, new bathroom, new dividing wall, and also another HVAC).

I checked the zoning and it's ok for multifamily (R3).

What else should I consider before making an offer? what should I check in addition to the regular stuff (inspection, contractor walkthrough, etc.)?

Are there any potential issues I should check in advance?

Thanks a lot!
