buying land NEED HELP (im new)

[Josh July]

I need help with advice. I am pondering an idea of buying land/lot(s) that used to have structures on it. It is in located in California, but in a more rural area... with hardly any other homes around. Most of the lots have or had septic and were/are on propane and electric is currently unsure; since events occurred and now electric that once used to go to all lots, now the lot(s)/homes will probably be powerless (maybe) for the next 3 months minimum or more(?); therefore, power/' electric might have be solar(?).  

I need help/answers

I don't have much money, but I may (for investment(s) ) be able to get private money and borrow from people I know...

I want to put together the property(s)/lot(s) under some sort of minimal liability LLC or Trust, because even though I don't have much to lose... I want to minimize my ties/ hide most of my identity; so that if someone tries to sue or take my property they don't get everything and might not know what I own or may own...

I want to know the best way to secure the land to keep people from dumping on it or living on it... the land right now is pretty worthless and I doubt someone currently would want to live long term there, but in the future amenities and with more people might move back/into the area, which currently right now is pretty darn rural and uninhabited. 

also, how would I find out if septic is still good since there were no issues before the structure(s) left or no longer stand...?

Also in terms of insurance claims do people have to wait for the claim(s) to be paid o before you purchase/acquire the property (land/lot)

I am talking about a strategy I want to use in CA and I want to save money and have a lot of time I can exchange to get/acquire land potentially
