Accuracy is more important than price to me as this is a small investment to get the right info.

Or at least find a better way to ensure accuracy.

No one on this forum can tell you that with 100% accuracy without knowing your facts and circumstances. 

It cannot be overly generalized too much or the cost looses its accuracy.     

In fact, their own claimed accuracy in my market is that 79.3% of the time it's within 10% of the sale price.

However, a preparer’s credentials and level of expertise may have a bearing on the overall accuracy and quality of a study.In general, a study by a construction Engineer is more reliable than one conducted by someone with no engineering or construction background.

We eventually went after that tenant in small claims court and won, but as Charlie said, the list exists but from our experience I wouldn't trust it even if I found it, given our situation and the lag / lack of accuracy, but also, it's not something that would readily be shared.

When using that data, be sure to check out their confidence intervals and accuracy reports to see how accurate the numbers are.

By doing this, we can all see the accuracy of this model.Makes sense?

My mentor also taught me to create a spreadsheet for myself and track who provides the most accurate information like my realtor, my software system, realtor.com, trulia, zillow and she said with time I would become more confident on the accuracy of the information and it's source.
