Is it a must to sign a contract with a realtor ?

[Lakeisha Baker]

I don’t want to sign a contract with one realtor because I’m not quite sure how the relationship will work. I don’t want to be roped into a situation where I need to see a property right away and they may not be available or they don’t understand why I’m not paying full price for a property. I would like to try out different realtors and make sure they will be a right fit for me. Is it necessary that I sign a contract to use a realtor?
