I want to make money, sure, but not at the expense of my customer's health or safety.  

How do I evict a family member/non paying roommate from my house that I own and live at in California with oral rental agreement that she would move out by the time her son got out of the mental health place which he is out now do I give her a 3 day notice or a 30 day notice ?

The owner bought this house at auction about 3 or 4 years ago, and then his health went way downhill and he has done nothing with the property.

@Lance Knapp I bought a senior health facilities reit.

Tenant informs me that he and gf have to move out several months early (mental health).

If I could find a property with a lot of curb appeal...would consider residents, nurses, allied health professionals at work.  

An orthopedic practice, such as KOC or TOC, will most likely want a completely different location than a new group of ortho doctors or even the new Contemporary Women's Health Clinic on Sherrill Blvd.Why is the group wanting a new location?

the tenant is responsible for the equipment.restaurant: fire supression system, health and safety. building kitchen to standard. 

I bought a pretty sizable policy after my wife and I had major health issues, which made a conventional term policy overly expensive. 

If you focus on the following, you can probably reduce your risk and not have to worry about the area getting worse for a long time:-access to public transportation, job and population trends, rent growth, vacant housing stock in the area, quality of school districtFor example....If you're planning to invest in a town with one large major employer (say a manufacturer) and that employer goes out of business or has a mass layoff due to an economic downturn, it doesn't matter if you own single families or multifamilies......there isn't going to be anyone to rent your units or buy your property.  99% of the time, a diversified local employment base is better (or atleast one that has many employers that are downturn resistant - health care, education, government, etc.)
