Live auctions

How do live auctions work? How do I use them as a wholesaler?

Live auctions? you mean foreclosure auctions? if your a new wholesaler than I would stay far away from that. I believe you need to bring cash to bid on those anyways.
Wholesalers job is to get houses under contract for cheap from motivated sellers and then to assign the rights to the contract to a buyers. Simple as that.
But if you do want to get more info on foreclosure auctions, there are books that you can read about them. Not for wholesalers though.

If you want to buy houses to make money you need to buy houses as low as possible. Auctions are designed to make you pay the most possible not the least possible. I am not saying that you can’t find a house cheap at auction (I bought one for $700) but there are not enough houses that you can buy that will work that you can build a business on it.
