Selling my ancestral fixer large property in LA and having trouble

[Nancy Noe]

Hi, I’m here to learn about RE investing since I’ve inherited 🙏🏽 from my parents recently.  First we need a good place to live, so I’m selling this large property with the house we’re living in, which is a fixer and it’s in a good neighborhood that builders like. 
The builders keep dicking around and trying to play us (I have a real estate agent but maybe time to switch).  They are all from one country and they are not straightforward so as a newb I’m afraid to not get everything this place is worth. 

I don’t know what to ask for, just that I respect the outside the box info I get here, and maybe someone in the LA area could kindly throw me a bone of a direction where I could find the right kind of RE agent (who deals in the almost $5m 
flips) or even any builder or investor who wants such things. 

I hate not knowing how much I don’t know. Thanks so much!
