Lure them in with a good deal then raise the price. Good way to advertise, not all fall prey to the psychological mind games though.

As the building began to take shape, the investors realized they had been swindled into purchasing a four-story edifice that was only 40 ft (480 in) tall, rather than the 480 ft (150 m) structure they were expecting.

They brought a lawsuit against McMahon but, to their dismay, the real estate and construction deal was declared legally binding by a local judge. As McMahon had built exactly according to the blueprints they'd signed off on, there was to be no legal remedy for the deceived investors.

Yesss... Always be prepared in case the dumb shmendrik figures out your shtick.
