Process of Purchasing Duplex with no Agent

[Danny Sibley]

Hello Bigger Pockets, I’m a new investor and I’ve recently come across a duplex off market. I’ve been talking directly to the seller and he is willing to not use real estate agents so he doesn’t pay commission. My experience is from books, podcasts and talking to other investors. I’m wondering what the process will entail through closing. Do I need to submit a formal offer if we have already agreed to all the terms or can I just submit a purchase and sale agreement? I was going to consult a lawyer before I submit any binding documents.
