How to price a property with duplex/ADU income potential?

[Laurie Horning]

Hi BiggerPockets Community, 

I am about to sell my first renovation project where I remodeled the basement into another living space (there is also a separate entrance to the basement). 

I'm located in Portland, OR and these types of properties are popular and this could be permitted as an ADU because it meets the height and square footage requirements.

I want to make sure I don't leave money on the table, how would I determine the list price given that it has the opportunity to generate rental income? (long term or short term)

Curious to know your thoughts, thanks!
