I have doctors as commercial retail clients and they all make tons of money I mean a lot each year.

Do local doctors and senior centers have bulletin boards that you can put flyers on? 

Things change if you have a profession where you need to worry about asset protection from the beginning (like a doctor where you can get sued and lose your rentals too).

I went into prison with a PHD in selling pot, and came out with a Doctoral in flipping Real Estate.

Examples would be karate school, doctor office, vet animal office, restaurant, dentist, salon, barber shop, gym,etc.People like getting out and living.

Same goes for doctors, dentists who own their own practice etc etc.So if you don’t want to partner, don’t have millions and don’t earn 100s of thousands at your day job, and don’t have enough equity in other properties, you’ve got one more option..Seller financing.

I will soon own a former chiropractic clinic that as the potential to have 7 or 8 bedrooms plus a 2 bedroom apartment on the lower level.

The property seems to cater to the lower end of the market but attracts some doctors, social workers, and related and unrelated types of businesses.   

As long as they have not sent you anything talking about "disability" or "treatment" or "emotional support" and there is no doctors note, how would you know this is anything but a pet?

They are mostly doctors attorneys and other professionals.
