Buying direct to Owner in Texas

[Sal Flores]

Hello BP's

What is the process to buy a property direct from owner in TX? 

I have purchased several properties using RE agent, but now I am looking to buy direct from owner, should I use the Texas regular contract?
"ONE TO FOUR FAMILY RESIDENTIAL CONTRACT (RESALE)" - Regular form
And then call the Title company and inform the intent of purchase?

Thanks for your support and guidance!!
