Should I buy a nonconforming duplex?

[Debbie Pelloski]

I want to offer on a duplex, as my first investment property, and the city has it zoned as single family, although it is registered as a duplex and a rental and I can continue to rent it as a duplex. Here are the 2 replies I received back from the community development director:

The records I reviewed showed it as an existing duplex. Thus, while it may be zoned as single-family, it may remain an as a nonconforming duplex as long as the use of the house as a duplex does not discontinue for 6 months. Thank you.

You could not rezone it because it would be illegal spot zoning. As noted, it can remain a duplex as long as the use is not discontinued. Thank you.

So my question is is this OK? Will it affect my plans to sell it down the road or any other plans? I would appreciate any input! Thank you in advance.
