Help from Massachusetts Investors, How do I find out which homes were bought in cash?

I live in the Saugus, Massachusetts area and I am really starting to get a great feel for home prices. I have a database of Sold Properties started and it has 230 properties in it.

My two questions are:
1. How can I find out which Homes were bought with Cash?

2. I know a Realtor may have this information but in Massachusetts is there another way?

If I knew this information, this would help me even more than just having a database of Sold Properties.

Your help is greatly appreciated :mrgreen:
