What is best way to find investment properties on public records

[Timothy Woodland]

I'm from Massachusetts and looking to purchase my first investment property. I've been doing research on public land records and was wondering what the best way to find properties that could be purchased at a discount. I'm able to find documents that have been sent to properties such as order of notice etc. What types of documents form the bank to the lender should I look for that would indicate that the home owner may entertain an offer before considering listing it on the MLS?

Thank you in advance!
