And then probably spent $150 or more on a chiropractor. 

You see this with many other small businesses in low regulation fields - autobody shops, chiropractors, landscapers, and above all small time landlords. 

This does not mean the tenants dentist, chiropractor nor one of many online sources that will, for $99, send fake documentation of the need for such.Some landlords will provide their own forms for the tenant to take to the appropriate medical provider for approval. 

The commercial tenant is a chiropractor.  

My chiropractor does some real estate investing and he said that if you buy and sell a property in less than 24 months, you do have to pay FICA tax on the profits.

Private Money Yes, The most recent buy and hold I bought with private money was funded by my chiropractor,  He wanted an investment, and I have a lot of those  We negotiated the return, and he wanted a 4% annual return.  

I thought she would learn that psychiatrists and chiropractors jobs are to keep you coming 'back' over and over.

A tenant threatening to call a lawyer worries me about as much as threatening to call their chiropractor.

But I promise if you have a good PM, there is little to no work or stress required on your part and you literally just collect the checks.I know a couple folks down in Whittier, and one of my really good friends is in chiropractor school out there!

Counseling, nail care, chiropractor, etc?
