What are the most important points to cover ?

Youll have to check if they cover the areas you're looking at.

We can not give you more advice outside of our area as our insurance does not cover them.

Pictures on Zillow and Google maps won't really give you a feel as to how it is walking around the neighborhood.

Purchase price: $340,000 Our 5th unit, single family home zoned for secondary suite.I will be covering this unit into an up and down duplex.

As stated above, the rental market your property is located in will be the deciding factor.If you feel, in its current shape you are competitive amungst other rental units, please feel free to share pictures and it’ll help with better feedback. 

This usually gives you a pretty clear picture of value, and you can infer the value of the subject property by adjusting for differences between it and the comparable properties (called adjustments).
