He has been a dentist for over 10 years.  18 months prior he purchased a dental practice from a retiring colleague. 

I Bought a dental practice with my wife 2 years ago, so once we are no longer poor from that, plan is to convert 3rd property into a STR.

Yeah..ok...And all teachers should have kids first...All doctors should have lots of medical issues before they can practice....All dentists should have lot of dental issues before they can practice...Every waiter should owner a restaurant before they can wait tables....Every car salesman should have bought multiple new cars before selling any....I get your point..... it would be great if every realtor had to have real life home ownership under their belt, so they have that BTDT experience..... but not gonna happen

Look for churches, daycare, elementary schools, dental offices, etc that can be converted to housing.  

Looking for a business loan for a dental practice and was wondering if anyone had experience or knowledge about SBG Funding.

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.... 

A women who was a Dentistry professor in her home country was my dental hygienist while she  retook her licensing exams in the US.

I work as a software engineer for Liberty Mutual Insurance and my wife is a manager at a dental office.

I have land that I purchased last year and would like to build a 6000 sq ft building for my dental practice.

the state exchange also accidentally canceled my dental insurance, admitted it was their mistake, submitted a ticket to the insurer to get it reinstated... and then the insurer refused to reinstate it and i had to wait until open enrollment to reapply.
