Robbie, Local to you CPA/PFS in Bryn Mawr we should talk shop and of course check BP Tax Finder and posts lots of great practitioners on BP.  

Love talking to a fellow practitioner.

I'm a nurse practitioner looking to diversify her portfolio and get into the world of real estate.

We've rented to a couple of Physical Therapists, a Nurse Practitioner, an Optometrist and currently have a travel nurse and her digital nomad finacee in our 1/1 unit. 

It should be from a local to that person's mental health practitioner or physician.

:) A good agent will meet up with you for a few hours, and along with educating you on the entire buying process (financing, contracts, inspections, what to expect in negotiations, etc) they will also be able to guide you by running comps and telling you if the home is priced well, as well as discovering any issues preventing the property from selling (liens, disputes)...Not sure about CA and AZ, But I have a buddy who renovated his dental office without pulling permits, and when the city found out, they made him literally gut it and redo it with permits.I would urge you having some conversations with agents in your area. interview a couple, and they should guide you in the right direction.

Preexisting dental office with equipment.

Within five years my wife plans to own her own counseling practice and I plan to be working as a Nurse Practitioner.

or commission based on introducing my coworkers (doctors, pharmacists, nurse practitioners, physician assistants, etc....all high income earners) to a real estate agent or broker.

More appropriate would be comparing the tenant to a dental patient   Both are receiving a service from a service provider.Best wishes
