Due diligence 2nd lien note in MA

[Sandra Helena Holtz Ivarsson]

Just came across a note(would be my first one). Believe its a re-performing and I just want to get my feet wet. 

I managed to find out that the taxes has been paid on the property. 

1. How do I find out if the mortgage aka first lien is current?

2. Does Minnesota require you to have a debt collector license?( is there a compiled list which states require a license and which dont?)

Thank you in advance sincerely Sandra a
