How to get massive data ?

[Lior E.]

Hi. I need some help as a new comer to this community. I wonder whether there is a way to analyze massive amount of data. I am familiar with the standard Zillow and alike applications. But if for example I would like to analyze a list of 200 houses in my area with the following: Property price Monthly Mortgage and other costs Monthly rental estimate. Net gain ( can be calculated ). The standard apps allow a one by one analysis. How can I import many data points into an excel and do a more massive analysis to conclude on deals faster. Thank you.
