.), please describe for me the worst-case scenario for an eviction process if the tenant refuses to leave at the end of a lease term (assuming I do everything properly according to MA laws)?

Just ensure this is clearly outlined in your assignment agreement.But in my experience, typically the wholesaler submits the EMD with the PSA to the title company for escrow.

Check their terms and fees to ensure they align with your needs.

I will have the Seller sign the Assignment of Agreement Addendum to ensure no problems.Appreciate the help.Loren

Seeing as how I'm not sure if you are communicating this properly, but one could be crossing ethical / legal boundaries --- maybe.Personally, the rental activity for that sort of property and tenant would not be worth the time.Thanks for letting us know. 

Quote from @Audrey Scott: My professional advice is to develop a clear repayment strategy to ensure timely payments and avoid potential financial strain. 

My mom would like me to assume the loan of her house to ensure it remains in my name.

Give them proper notice and get them out2. 

Does it have to come from an Attorney or is that simply the best way to ensure Notice was given and to minimize issues if Foreclosure is necessary? 

I’d recommend reviewing your lease terms and following what’s outlined there to ensure you're on solid legal ground.
