Some actually did made off like a bandit without doing any kind of modeling, using the old fashioned way, common-sense, by just calling out and comparing quotes:

Someone sold four-bedroom home in Phoenix to Zillow for $531,300 in late September at much higher offer than $504,000 solicited from a competitor. Ten days after Zillow bought the home, it listed the property for $505,900. When it didn’t sell, the company cut the price by another $11,000 to $494,900.: https://lnkd.in/eEgA-jQH :

#Buy #Hi & #Sell #Lo vs #Buy #Lo & #Sell #Hi
Given the above evident Zillow pattern of Buying-Hi and Selling-Low, anyone could have positioned oneself on both sides of the transaction by Selling-Hi and Buying-Low, the simple #CommonSense #Arbitrage that has been evident for thousands of years in all market-making activities long before anyone heard of #Econometrics or #QuantitativeFinance.
