Hello BP,I know this is not a question that has a "right" answer but I feel the need to ask it anyway.

wow your answer is so helpful and clear.

To try to make a long answer to a shorter answer I'll try to make my point. 

These are all questions whose answers will help you chart the way forward ... there is no one size fits all answer.From an operational perspective it is always pleasant to know that your building envelope is relatively efficient (insulated and air sealed); that building systems (electrical, plumbing, HVAC and communications are up-to-date and dependable) and that you have the ability to put accountability for resource consumption in the hands of the tenants.  

I know the answer is yes, but I'm just wondering what all your thoughts are!

Of course, the typical things to look at are the crime, schools, affordability etc.Happy to answer any questions and also make my self available for your July house hunt.

I’ve been looking for these answers, and it seems it just comes down to doing some due diligence research to find decent contractors.

Does that answer your question?

At the same time I want to find answers on taxes of installment payments with seller financing.

But to answer your question you report income the same way you would with any other 1099 position.
