not at all. my realtor set me up with a portal for free & i looked at over 360 houses online, maybe 20 in person, free of charge. when i finally bought my place, he helped with all the paperwork, and when i signed, he got his fee. i'm there are details to be gone over before starting, (such as committing to buy through them and not someone else), but that would be the honorable thing to do anyway for someone who's investing so much time with you.
