Realtors commission split?

[Allen Lopez]

So I found a property that I really like. It’s a pre build property so I have the option to buy it from the builder or get a realtor. If I buy it from the builder, the builder saves the commission. If I use a realtor (any realtor), they would get nearly 5-7k free. Keep in mind that they would not have showed me any homes, or done any work.

1) is it recomendable to use a realtor?

2) would it be wrong for me to ask the realtor I pic to split their commission with me or something since they really didn’t do much?

3) I will probably use this realtor in the future for other properties. So asking this might offend them.
