My mother is an agent in SB; she enjoys working with investors a lot, she also knows construction fairly well, and really goes the extra mile. 

I am looking for assistance on what are my options for my 3 unit house passed down to me my dad from my deceased mother.

We like to pretend we are wizards, but the fact is that even the best lender in the world is not capable of controlling when your mother will die or what stupid thing the listing agent will do or when unknown medical debt from 15 years ago will suddenly pop up.

I always strife to be a better individual and being successful to be able to take care of my mother and little brother who i have never seen before, both residing in Ghana.

While I am not familiar with CA zoning, I know in some areas that a mother-in-law type suite is not a separate dwelling and must share utilities and often can not be rented out.I would confirm this personally with the zoning department, and not just trust the Architect, since you dont have previous experience with him.

The mother died and left the house to both the son and daughter (and apparently left one of the sons out...).

I have a potential seller that called in from my Direct Mail campaign stating that his mother passed away 12 years ago and he owns the land, he mentioned that it had been in his family since the 1950's and he has only seen it once.

Have my father drive people to and from the casino while my mother does the cooking.
