One way to access the multiple listing service for Niagara Falls, New York, is to go through a Realtor, according to About.com. People selling their properties themselves can also pay a set fee to a discount broker, and the broker enters the information into the MLS database.
Realtors also make their listings partially available through their websites and other sites, says the National Association of Realtors. Data that might lead to loss of privacy or safety for sellers is omitted from the public listings. Such data includes the sellers' contact information and the times they are out of the homes for showings.
The MLS information that the public can access is frequently outdated, limited and wrong, reports About.com. To get the most updated and accurate listings, a buyer or seller should ask his Realtor to customize a comprehensive search report, which is not the same as a customer copy. The real estate agent supplies the customer's email address and search criteria into the database, and the customer gets information that is as live as possible, which he cannot get elsewhere. Ways that a buyer customizes a search include by ZIP code, subdivision, number of bedrooms, number of bathrooms and by amenities such as pools.
