However I have been doing some market data posts on the blog to put some strong local keywords out there without stuffing them in there.  

I've come to notice that every piece of data in the newspapers are on websites like foreclosure.com already and it makes the morning paper look like old news.

I suspect census.gov has some data that would help sort markets with high rents and low values but have not found it.

However, with the availability today of so much data, many intelligent conclusions can be drawn simply by procuring and evaluating the data.  

However, life may not be good if within the next 3-5 years interest rate soar up above 6%.So that got me to thinking on whether or not there is any reliable data out there on forecasting future interest rates.  

A better way to split this up is to look at tax assessor data.  

Keeping that in mind, just download the bank details and let QuickBooks enter the data is not going to be sufficient.

seems like it pulls data from zillow

To answer your questions It doesn't matter what kind of software you are coming from they are going to tell you to export your data and fit it in to their google spreadsheet.  

While the data is excellent and affordable, it isn't intended to be the only tool in your tool chest.
