Saw my first real estate property, how does a double close work ?

[Eli Hood]

So yesterday, for the first time i had an appointment with the owner of the property, i went in and he showed me all of the rooms. I honestly like what i saw. Now how does a double close work if i found a cash buyer and i wanted to flip it ?

By the way, the mortgage is paid off, couldn't i seek owner financing as an other option ?
