Why all the hate on wholesalers?

[Nate S.]

I read alot of stuff online, including on this forum bagging on wholesalers because their making money flipping contracts. Honestly I see wholesalers saving time and money for investors, more like marketing agents for real estate, trying to get investors the best deals which time to me is the most valuable asset. I don't understand why all the hate on wholesalers? 

The house I inherited is teaching me alot I didn't know about fixing a house, knowing little bit more what investors look for. While I'm doing wholesaling even though I've haven't done a deal yet but working on getting my RE license at the same time(yes, I'm aware you have to disclose).

I think a lot of the negativity comes from the fact that wholesalers claim to be cash buyers. If you want to wholesale a property you should buy it and then sell it. Tying someone's property up in a contract when you have no way to close without a third party coming to the table, is shady IMO.
