Davin, Not sure exactly what you mean, but...if there is a Realtor sign in the yard, that means the seller (whether that be an individual or a bank) of the house has listed it with a broker (Agent). The listing will be an agreement for a period of time, like 30-180 days, during which time the agent tries to sell the house, and if he/she is successful they receive a commission of 5-7% (or whatever was negotiated).
The seller could be selling for a variety of reasons. He could be motivated, or not. He could need the cash from his house to buy another, or not. He could be in preforeclosure, and the hbouse could be a short sale or a REO. Or he could be dead and the hosue is being sold by his heirs. All kind s of reasons, so to answer your question, there could be a "deal", or not. Best way to find out ios to call the agent and ask what the circumstances are, and you will then know whether you should make an offer or not. You are less likely, in general, to be able to wholesale a house that is listed. It is better if you can find a motivated seller and negotiate with them directly to buy the house at t discount - no agent involved, so you can avoid the sales commission. Good luck, Mike
