You may purchase an AVM from all of the following EXCEPT?

An Automated Valuation Model (AVM) is a technology used to estimate property values based on various data factors, including property characteristics, market conditions, and comparable sales. Fannie Mae and Freddie Mac are government-sponsored enterprises (GSEs) primarily involved in mortgage financing and securitization. While they may incorporate AVMs in their processes to assess property values for underwriting and risk management, they do not directly sell or offer AVMs to the public.

In contrast, CoreLogic and ATTOM are companies that specialize in real estate data and analytics, including AVMs that they market and sell to lenders, investors, and other real estate professionals. Thus, the correct answer highlights that Fannie Mae is not an entity from which one would directly purchase an AVM, differentiating it from those which are privately owned companies specializing in such services.
