It is unlawful for a dealer to do which of the following?

In the context of commercial modular sales, it is unlawful for a dealer to engage in any of the practices listed in the question. Each of these actions is prohibited as part of maintaining transparency and fairness in advertising practices in the manufactured home industry.

Advertising a manufactured home without its serial number is illegal because the serial number is essential for the identification of the unit. It helps prevent fraud and ensures that consumers can verify the specific home’s details and history.

Excluding fees from advertisements misleads potential buyers. It creates an inaccurate representation of the total cost, which can result in consumers being surprised by additional costs at the point of sale. Transparency in advertising prices, including any potential fees, is crucial for informed decision-making.

Representing documentary preparation fees as governmental fees is also unlawful. This practice can mislead consumers into believing that these fees are mandated by the government when they might not be. It is essential for dealers to clearly differentiate between legitimate governmental fees and those that they impose, ensuring that consumers understand what they are paying for.

Due to the importance of these regulations in protecting consumer rights and promoting a fair marketplace, all of the actions outlined in the question are deemed unlawful for dealers. Thus, the correct answer indicates that all these practices are prohibited.
