Prove your ability to buy to them and provide POF for $1,325,000 and net-worth statements, or a plan to obtain that through established relationships.

Already mentioned up here, but breaking down into points: 1) 401k/qualified profit sharing can only be established by an employer or self-employed person.

Establish a relationship and continue to come back to visit the parks you'd like to work in.
