1st time - Master Lease

[Victoria E.]

I'm recently learning about master lease. I was negotiating seller financing with seller but it didn't go well, so I'd like approach him with master lease.

Would you advise on what I need to know about master lease?

What's the repair amount I should be responsible for and what's his?

Where can I find some contract/forms for this and what to record?

I'm in Los Angeles County. Thanks for your input!
