If you were to find things wrong in the inspection due to these factors that would cost a lot to repair, the seller may be willing to go down on the price.

That is an X factor that you can't really predict. 

Personality and attitude all factor in as well as the hard facts of screening.....credit, income, employment, landlord reference, and multiple personal preferences.

As a matter of fact, i never even factored in snow removal and landscape (even thought its a small patch of lawn and some bushes. 

@Tom Gimer I saw that was a factor in FL adverse possession. 

How do you analyze the land you want to build in, what are the most important, if not all of the factors and elements to keep in mind and research?

That leads to fewer maintenance costs and longer occupancy.Each of those factors will absolutely effect the long-term performance of any property - not just a Turnkey property.Lastly, if you want to just cut straight to the chase about returns,  expect to lose 50% of your rents annually and reflect out over 10 years.  

Be certain that you factor this into any financial analysis.  

I can tell you that unless the structural damage and subsequent repair is obvious, it will not be a factor in an appraisal.

A lot of factors to consider but for me, the most important was the managing broker.
