Every realtor is out to cheat you somehow, if the price seems too good to be true there's some hidden gotcha you're missing, and once you find a property you like it's best to find your own people for everything to minimize the chances of them colluding to really screw you over. If you have friends have them recommend people to help you. There's a number of steps where things can go horribly, horribly wrong in ways you aren't used to. Pay particular attention to the part about bringing the purchase price in cash to closing in a trash bag full of $100 bills and plan backwards from avoiding that part going wrong.
I'm going to reiterate the part about the real estate agents being absolute garbage, like, they failed out of used car salesman school for being too sleezy so they went into real estate instead. If you're buying in the provincia I can provide recommendations of people I worked with who were honest, CABA someone else will have to give you recommendations.
