We own a home in Weaverville, CA which we bought at a Trinity county tax deed auction and are now exploring options for an ejectment of the tenant and want legal help.

Hoping you can all share your experiences with tax deed sales and possible eviction or ejection in CA.

IE the property gets put into an LLC that you can DHM own.. if you fail they just eject you from the LLC and take over.. so they don't have to foreclose..in the states back east foreclosure is costly and can take a ton of time.. therefore in your markets..

It looks like a will have to file an ejection opposed to an eviction since there is no lease involved.  

NC General Statutes - Chapter 42 29 (4) Any unpaid bills that become a lien against the demised property due to the tenant's occupancy. (5) The costs of re-renting the premises after breach by the tenant, including any reasonable fees or commissions paid by the landlord to a licensed real estate broker to re-rent the premises. (6) The costs of removal and storage of the tenant's property after a summary ejectment proceeding. (7) Court costs. (8) Any fee permitted by G.S. 42-46.

You can file for ejectment immediately.Often, once the investor indicates that it plans to take possession of the property, the owner will begin redemption.

I looked at a park for someone a few years back in Nebraska and the pond was ejecting directly into a stream.

That is virtually impossible to prove. (3) you have an ejectment order from a court after filing an ejectment lawsuit against the owner. 

It did have someone staying in it, I couldn't do ejectment immediately.

One requires a simple eviction action; the other most likely requires an ejectment/trespass action.
