Realtors and Contracts

[Mateusz Prawdzik]

So just a quick question. So lets say I find a house on MLS, I go look at it, I put an offer and I want to contract the house with the owner. Does the realtor have anything to do with the contract or she/he is just there to show me the house? Additionally, should I form my own contract and make it a personal written agreement or should I get an attorney involved? Do the realtors take a fee for the contract?

I am just getting starting wholesaling and I definitely think that this deal is going to be big. Please if anyone can give me some insight that would be great.

Thanks in advance, 

Matt
