My wife and I are currently starting out real estate journey. 1.5 years ago we bought a dental practice, and last year we purchased our dental office building priced at around $2M with $500k in equity.

Were you offered benefits of any kind: medical, dental retirement?

YOU would certainly do it for much cheaper, likely less that $60 (cost of doorbell) if YOU did it... you would also do it cheeper if you did your own dental work.... 

I am seeing corrections officers, maids, dental hygenist, retired vets...I mean, good income earning professions are filling out my rental applications.

The owner has a tenant who is using the property as a dental office but he hasn’t paid in almost 5 years.

A single tenant investment grade BBB-  or better the odds of default are very low and passive.If you had Aspen Dental, T-mobile, Starbucks 3 topper with corporate guarantee and 10% increase every 5 years then different ballgame then mom and pop tenants.It's all in the details that makes the difference which way you might go.STNL credit tends to sell at lower cap rate also with longer term leases.

The drawback I have is that it is difficult to pounce on properties that are still selling relatively quickly with the commitments I have  to my patients in my dental practice.  

Maybe you love it, maybe it's like dental work, who knows. 

Additionally, you have to consider healthcare, vision, dental, etc...
