Purchasing Foreclosed Mobile Home Park

[Ginger Unger]

I am purchasing a mobile home park that was foreclosed on in Texas.  The previous owners granddaughter, mother and brother live there and have all been served eviction notices.  They are selling mobile homes in the middle of the night out of the park.  There are no plates on any of these older mobiles homes.  They are telling Tenants to vacate the mobiles because they have them sold.  How do I stop these people from selling property they do not own?  They think since they are still in the park they can do as they wish.  HELP
