What are the most important points to cover ?

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

@Ben Narro     In California, some of the credit unions offer RV loans that should cover a tiny home on wheels.

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). 

My second event i went on Craigslist to find an ad came across an ad saying Become a real estate investor earn while you learn, thought i give it a shot this guy was telling me about Renatus and great mentors they had he invited me to a meeting in south jersey on a Thursday night to watch a guy name scott rowe who has made millions of dollars off real estate education, before i went i had to research what renatus was and who these people the guy was telling me about needless to say i was skeptical about rowe and this guy name brian meara they said he does shortsales and i ask the guy who invited me what shortsale was and he said the host will tell me, sounded like he didnt know what it was either, for the most part all he said was that this was an opportunity of a life time, wasn't sold on that either so i sat there for about an hour and 20 minutes listening to scott say he was from Chicago show me picture of  his community a pie chart how to get into renatus how to pay for very expensive education how to get the money blah blah blah caught in quick that this was an mlm meetup.

Never a bad investment opportunity if the income generated from the property will cover all related expenses.
