I work out the Coldwell Banker office in Highland Park - zip 55116. I am very familiar with St . Paul neighborhoods and have worked on several lender mediated sales. In addition since I work in a very large office and I have the connections to become aware of pre-MLS properties. Give me a call 651-357-0435
There are several fabulous Coldwell Banker Burnet agents that work in those areas (I don't specialize there otherwise I would be hopping up and down for you to contact me :)). You could call our office on Grand Ave, 651-227-9144 or our office in Highland, 651-698-2481. Ask for the manager (Tina at the Grand office, Kathie in Highland) and ask for their suggestions.
Best of luck!
Wishing you much success, Jack:-)
