What's Stopping Investors From Undermining the Wholesale Agent?

[Will Pham]

Hey I'm new to the wholesaling business, and still in the early stages of learning.   After a lot of reading and research, I am confident that I understand the parts of the wholesale transaction and marketing strategies to find potential seller and potential investors/buyers.  What I'm trying to figure out is what is stopping an investor from taking a look at the property that a wholesale agent is trying to sell, and then making the home owner an offer slightly higher offer to buy after the contract between the home owner and wholesale agent expires?  

For example, lets say the wholesale agent works hard to find someone that is a motivated seller and contracts to buy the house for $75,000 

The wholesale agent then finds a potential investor at a foreclosure auction and makes an offer of $90,000 and then gives the potential investor the details of where the house is. 

The potential investor then takes a look at the property and after talking a little more with the wholesale agent and the seller, learns that the contract between the wholesale agent and the seller expires in 2 weeks. 

The potential investor waits until the contract expires and then makes the seller an offer of $80,000 thereby giving the seller $5,000 more than they originally would have made and saving the investor $10,000. 

My guess is that the only thing keeping the potential investor from doing this is the fear that the house will sell to a different investor before the wholesale agent's contract with the seller expires.  

Does this make sense?
