Owner Finance How does it work?

[Danny Dang]

Hello this is my first post. I'm about to buy a 4 plex in Arlington, Tx and the owner will be doing the financing. Where or what should I do to protect myself? What if he just takes my money and still keep his 4 plex? Who or what should I get involed to land this deal?

Thanks for help in advance. This would be my first deal ever on real estate investing! I hope it goes ok!
