My brother was a nurse at Mt Carmel which is just west of downtown Cbus, due to his ER experience there, I would avoid that area. 

Most of the jobs are in corrections and nursing, the manufacturing jobs here are Bombardier and Nova bus.

That being said, San Diego has a huge demand for corporate short term rentals, traveling nurses, military etc.  

Some are looking for small spaces to furnish and put a traveling nurse in.

It's hard to judge "cars in the parking lot during the middle of the day" because you might have nurses, security guards, etc. living there that work off-hours. 

You can get a little better returns from students if you get just a little farther from the school and rent to grad/med/nursing students who take better care of the property, but there's so many homes close to the school (Tech Terrace - $500-$600/bedroom) and other neighborhoods where you can get a good return as well. 

I know I’m talking to a very small group of people here, if any at all... but are there any nurses on BP who currently work as travel nurses and invest in real estate??

I was a registered nurse and thought "this is your next step" following the same pattern as most Americans.

I work full time as a Registered Nurse and love my job, I'm not a real estate agent, and don't want to be.

The reason they're selling it so low is because a family member died or was put in a nursing home and the owner of the house and the person that was living there is in the same family.
