Not using a realtor on a purchase - advice needed

[Prab C.]

A wholesaler recently shared an off-market deal with me. The seller doesn't want to put it on the MLS to avoid paying heavy realtor fees. The wholesaler is not a licensed real estate agent.

How important is it to have a realtor involved to represent me on the purchase? Have any of you purchased off-market properties directly with a seller without realtor involved? Any tips/advice is appreciated.

Thanks!
