Owner says I can run my own cattle on the property

Just took a job managing a place on the central coast CA. We currently have a neighbour running cattle on the property for a negligible cost per head. The owner would like to start running his own stock on here and would like to do it in partnership with myself. Any advice on how to buy into the market and things to be wary of in regards to going in on it with a partner?

I just moved here from a bigger outfit in Idaho and have a decent amount of experience working cattle I’ve just never ran my own so any tips would be appreciated. Thank you.
