My partner, who is a dentist, and I acquired out first commercial multifamily back in February.

If you are buying a $48k property, you will get a different level of service than someone buying a $500k house.Do you expect your dentist to do a good job on your one filling even though another customer is doing 4 and giving them more money?

It isn't a problem I've faced, so I don't relate.Have you tried "Private Money" say from a Doctor or Dentist or a successful businessman?

Users ranged from a dentist, chiropractor, craft shop, insurance agency, mortgage broker, etc.

Doctors, Dentists, Lawyers should have their spouse use that loophole. 

i am real estate investor since last 30 years .i am a dentist

IE For dentists it's American Dental Association.

If hard money lending is so good why doesn't your dentist do it?

I am 100% sure that a plumber making 80k a year can outperform a dentist who makes 250K in wealth and is not difficult to start from a young dishwasher and become a multimillionaire in his lifetime.

pros on the dentist office is that it is likely a long term lease, less maintenance, and a more stable tenant.
