Costs associated with transaction

[Sahegin Charolia]

I was trying to find out if I am looking for a house for flipping and I get the house from a wholesaler, what are the transaction costs associated with buying from a wholesaler and selling it on MLS or to an investor. So far I know when buying there maybe a closing costs (depending on wholesaler) and agent fees when selling on MLS (6%). What other transaction costs are usually factored into analyzing a deal that it's a cash deal.
