I've been a software developer for 17 years specializing in Microsoft technologies and have my BS degree in Information Systems.  15 years ago I started learning about RE investing from a co worker that was embarking on this journey, and I read books like Rich Dad Poor Dad, Cashflow Quandrant, Total Money Makeover, How to Win Friends and Influence People, and other various "motivational/self-help books".  

My main projects are in personal development, self-help and life improvement.

If the property is held in the name of decedent, you'd need a RM balance leaving sufficient equity to cover the costs of the title fix.....which assumes there are known heirs whom can act as admin/exec in a probate action.  

Since you are self-managing I will answer your question from there.Here is what I would do after taking over a new property (not in any particular order):0.

I already work as an virtual assistant to a couple of investors who self manage their own rentals. 

That's going to fall under the umbrella of self help eviction and that is a no no.You are in California that is a very tenant friendly state.

Since 2009 I have self managed the house we bought because we are under water.

To merge Marcel's and Bob's ideas some (and I think Bob is spot on that most association managers would feel this is their job and maybe even some encroachment on it, as working with vendors is right in their wheelhouse)....Maybe narrow your target market to (1) Self managed condo and homeowner associations.

I have an LLC, recently opened a self directed IRA. 

It is better not to open one's self up to liability, especially when it is a Class 1 Misdemeanor in my state and in many states to do unauthorized practice of law.
