If you don't know some of this information or you don't know how to analyze this data then you should probably hire some local professional advisors to assist you in looking at the financial ramifications of this lease to you. 

Local services typically just provide an excel file with new notices, or something similar - typically they don't match and append assessor records, track auctions, etc but it's a start.You could also consider using one of the national foreclosure data services - foreclosure.com, foreclosures.com, realtytrac or realquest.

One of the issues I'm guessing you may be hitting is finding data about the specific parcel.

I created a excel sheet where I insert data and it shows also a graph.

Then there is the rental data for the area.  

Are you a gifted data cruncher and love spending 40/hours a week analyzing properties?

With data pulled from multiple sources.

Hello Elicia,Virtual assistants are getting more and more popular in property management.We use virtual assistants for a lot of our data processing.One of the things that we have our virtual assistants do is send a survey monkey survey out to our residents after a maintenance request has been completed.Another thing that we have our virtual systems do is post our available rental properties on some of the rental websites for additional marketing.We also use virtual assistants to update our property management software.We have a different set of virtual assistants that specialize in handling after hour maintenance calls.Virtual assistants make us much more efficient and free up our PMs to stay on top of their emails and phone communications with owners and tenants.

Leaving data out yea, but will fill in.
