When is a buyers agreement signed?

[Juan Alvarez]

When does one sign a buyers broker agreement?. Things are not working out with my current agent so I’m thinking about moving on but I am not sure if I ever signed a buyers agreement. I have made a total of 7 offers, 1 got accepted but I backed out of the deal. I went through the copies of the of the contracts but I cannot find anything. Should I just move forward ?
