How To Execute A Contract On This Deal?

[Brian G.]

Hey BP,

My dad has found a motivated seller in CA.  They want cash for the property.  He is in the process of getting the cash together via private lending, by next week.  He does have $5K right now to work with and it's a private sale (no realtors).  

How can he get the property under contract (tie it up) so that no one else is able to purchase it while he gets the remaining cash together?  

Other than seeking out a Real Estate attorney what would you advise? 

What are the right steps?

Thanks!
