I've been too busy rehabbing my 3 unit apartment building to really focus on anything else.But nonetheless, I have been keeping up with my less-than-professional deal pipeline.My first question regarding this involves raising capital to invest in deals.

I would give the tenants the option of moving somewhere else or accepting the situation.As you pointed out, your "therapist" is using your residential rental as a business, which is a violation of your lease.

I am a partner in a mobile home business.

That said, owner occupants are not business people and often don't make the best financial decision.

The private lender runs "a trade or business", like hard money lenders and professional money lenders do, as opposed to a casual lender such as a friend or a family member.2.

Either way, I will call but wanted to see if anyone here had any knowledge....It will likely increase your insurance rate because of the business activity/liability. 

Which will bring plenty of other investors and general business to the area.

Look for: longevity in business, warranties their work, and a "fair" price (not the cheapest!).

If you have plans to grow your investment business, I recommend getting it set up now.
