What are the most important data you need to invest in properties?
Hi there, I'm working on a [property fetcher](http://soon.propertyscout.club/) website that basically after having defined several parameters and filters sends out a weekly list of new properties on the market...what I want to add is a highly insightful list of the data to come along with the property listing (i.e. owners, previous prices, remaining lease etc...) ...

What I'd like to ask you is what are the most important and hidden data that you may find highly useful before making an enquiry for an investment?

Thank you very much!
