Thank you for your response.

I'm a fellow San Diego resident who is also interested in multi-units OOS.In response to your question, from the research I've been doing (and outside of the residential vs commercial aspect that @Sherwin Gonzales brought up), a big part will be your comfort level and financial goals. 

@Matt Stewart  Thanks for the response, Matt.

Thanks Joel, your response is extremely helpful going forward.

On the CRT website, one type of dispute they will look at is "issues of financial responsibility for repairs and the choice of bids for services."

First, preparation is crucial because money is made when you buy.

Thanks for the response.

Whast do I do what am I responsible for? 

Thank you all for your responses and I will definitely reach out to those you recommended and see what makes the most sense for us.

If you signed a lease that told you that you are responsible for repairs if damage occurs, then you landlord may have a case for the toilet repair.
