Let's emphasize that last part: the potential concern list is endless. That's a contradiction, and a trap for buyers. What you're saying is that a buyer is supposed to check out an endless list of possible problems with each property under consideration, and that the seller and the government bear no responsibility to help, even if they KNOW about possible problems. How is that supposed to ever happen? The whole setup is a rigged game! Remember that in real estate, The Government makes and enforces The Rules, so they should have expertise in the area. The sellers are often developers and such with lots of experience and expertise too. Meanwhile the buyer is NOT an expert - and even if the buyer has an agent, the agent often only makes money if a sale happens. Also this: Back in the mid-2000s, the real estate market here was REALLY hot. A house would go on the market at noon on a weekday, a crowd of buyers would be there ahead of time to see the house, and there would be three full-price no-contingencies offers before the sun went down. How could anyone "perform due diligence" in a market like that?
