(probably a realtor agency who is located closer to their house).  

Although the sellers being unrepresented many times will sell for far less than what a good broker could have gotten them for the house.As an agent you open your self up to challenges if buy a property too far under market and the idea is that you took advantage as a professional of the poor seller ..As a private investor you don't have those Ethics issues and agency and fiduciary issue.

Now...you do need to stomach the frequent little repairs, sometimes late collections, state or federal agencies (who pay a portion of the rent), and/or sometimes the out of place request, but that's worth 10% for me as I only get about 1-2 calls per month from my PM :)Best of luck how you proceed...

I am currently studying for my Colorado real estate license, reading loads of books on real estate investing, listening to the Bigger Pockets podcast, and working at a real estate agency in the marketing department. 

There are companies that provide agency for foreign (out of state) entities for the purpose of legal process service. 

Over the last 2 years the 2nd mortgage holder had given approval many times and waited patiently for the first to approve.Now that the first has approved the sale, the 2nd, Ocwen, wrote off the debt and sent it to a collection agency.The collection agency will not budge on their payoff amount demands which is 3x higher than Ocwen would have accepted, and the primary mortgage will not meet those demands.Is there anything that I can do to get this deal completed, or is it just dead?

Check the Mass State Housing Agency.

We aren't even at agency law or basic contract law.

My firm is a seller servicer for all of the agencies so happy to answer any questions on the programs. 

@Moziah Scott If that is truly the case, you always have the option of calling the agent's broker and/or reporting the incident to the state licensing agency.
