How Does OneKey MLS Work?

New York has multiple regional listing systems. OneKey MLS helps participating professionals find and research properties, while a flat fee listing lets a seller obtain brokerage listing entry without hiring a full-service listing agent.

FlatFeeMLSNewYork.com is an independent flat fee MLS listing service. We are not affiliated with, endorsed by or partnered with OneKey MLS. This guide explains the system, not an official MLS offering.

What Is OneKey MLS?

OneKey MLS was formed in 2018 following the merger of the Hudson Gateway Multiple Listing Service and the Multiple Listing Service of Long Island. It is a regional multiple listing service used by participating brokerages and their licensed subscribers, not a statewide monopoly or a website where owners independently upload listings.

The listing brokerage maintains the property facts, price, photos, description, showing instructions and status. Other authorized professionals search those records for buyers and market research; sellers do not receive their own professional MLS editing login.

Where Does OneKey MLS Serve?

OneKey MLS covers a broad region of downstate New York and the Hudson Valley: Columbia, Delaware, Dutchess, Greene, Orange, Putnam, Rockland, Sullivan, Ulster and Westchester counties; the Bronx, Brooklyn (Kings County) and Queens; Nassau and Suffolk on Long Island; and portions of Manhattan. Regional coverage does not guarantee placement for every address. Whether a listing can go on OneKey MLS depends on the property's specific location and the applicable listing arrangements, so we confirm the correct system from the exact property address before accepting an order.

Brooklyn, Manhattan and Staten Island are reviewed individually, not assigned automatically to OneKey MLS:

• Brooklyn (Kings County): Brooklyn properties may involve OneKey MLS or Brooklyn MLS. The supported route is confirmed by the broker before an order is accepted.
• Staten Island (Richmond County): Staten Island is served by its own board MLS. Coverage is confirmed individually before an order is accepted.
• Hudson Valley counties: Dutchess, Orange, Ulster, Putnam and nearby counties are confirmed from the exact property address.

How Does a Flat Fee Listing Get Entered?

After address confirmation, choose a package and supply the signed listing agreement, required disclosures, property facts, asking price, description, photos and showing instructions. A participating licensed brokerage reviews the materials and enters the listing under the applicable MLS rules.

• The brokerage handles MLS entry. It reviews required fields and maintains the professional listing record.
• You handle your sale. You remain responsible for showings, buyer questions and negotiations within the scope of the listing agreement.
• Changes go through the brokerage. Request price, photo or description updates rather than trying to edit the MLS yourself.

Our listing process explains the service steps, and the New York MLS listing guide covers preparation.

How Does Listing Information Reach Zillow and Realtor.com?

After brokerage entry, listing information may be distributed to Zillow, Realtor.com and other public websites under applicable permissions and data-distribution agreements. Professional MLS access, broker website display through Internet Data Exchange (IDX), and consumer portal distribution are different channels.

Each website controls its own timing, layout and inquiry routing. Updates may arrive at different times, and appearance on every website is not guaranteed. MLS data sharing does not mean a listing is separately entered into every MLS or displayed on every local public portal.

Can Sellers Change Their MLS Listing?

Yes. Send price changes, replacement photos, description corrections and showing updates to the listing brokerage. Our packages include unlimited listing changes, subject to applicable MLS rules and brokerage review.

How Much Does a OneKey MLS Listing Cost?

These are our brokerage listing-service package prices, not fees the MLS sells directly to homeowners:

• Standard, $149: 6-month listing term, up to 25 photos.
• Premium, $188: 12-month listing term, up to 50 photos, Open House Alerts included.

There is no surcharge for OneKey MLS. Compare our flat fee packages. Any buyer-agent compensation is a separate negotiated decision, not part of the package fee.

What Happens When the Property Goes Under Contract or Sells?

Notify the listing brokerage promptly when an offer is accepted, a contract falls through or the sale closes. The brokerage reviews the information and updates the MLS status according to applicable requirements. Public websites refresh on their own schedules.

Frequently Asked Questions

Is OneKey MLS the same as Zillow?

No. The MLS is a professional listing database. Zillow is a separate public website that may receive listing data under distribution arrangements and controls its own display.

Does OneKey MLS exclusively cover my address?

No. MLS service areas can overlap, and our city registry is not an exclusive boundary map. We confirm the appropriate listing environment and service availability from the exact property address.

Is there an extra OneKey MLS surcharge?

No. Our Standard package is $149 for 6 months with up to 25 photos. Premium is $188 for 12 months with up to 50 photos and Open House Alerts. There is no surcharge for this MLS.

Can I enter my own MLS listing?

Not directly through our service. A participating licensed brokerage reviews your agreement, property information and photos, then enters and maintains the listing under applicable MLS rules.

Will every public website show my listing?

Not necessarily. Distribution depends on permissions, data agreements and website policies. Zillow and Realtor.com control their own timing and presentation; placement on every website is not guaranteed.

Can I change my asking price or photos?

Yes. Send changes to the listing brokerage for review and MLS updates. Our packages include unlimited listing changes, subject to MLS rules and brokerage review.

What happens when my property goes under contract or sells?

Notify the listing brokerage promptly when you accept an offer, a contract falls through or the sale closes. The brokerage updates the MLS status under applicable rules; public websites refresh separately.
