First deal - Is this even possible?

[Christopher Gonzales]

Hi all!
As some background, I am new to the real estate investing community, and have a possible seller financing opportunity to pick up my first piece of real estate.  

My big question is, is what I’m think even possible?? 
Can a deal be set up where a payment schedule is set based on what both parties agree, and can the buyer have access to 100% of the property’s equity (seller owner at the moment - no mortgage) at the start of the agreement?

I feel like the answer is, ‘duh! Yes! That is the definition of Seller Financing’, but I am definitely in that first timer, check thrice do once mode. 

If the answer is yes, my follow up would be, any real estate attorney referrals in the Southern California area? 

Thanks all!

Chris
