Pre-Market or Public? How St. Louis Sellers Should Launch

If you have been reading about private listings, you may be wondering whether your St. Louis home should launch quietly before it goes public. It is a fair question, and the right answer depends on what you want from your sale.

Quick answer

• Most sellers do best with a public launch from day one, because more buyers see the home at the same time.
• A short pre-market or quiet launch can make sense when privacy or timing matters, but fewer buyers see the home while it lasts.
• National rules allow these options, and MARIS sets the St. Louis details. Get any pre-market plan in writing.

What Clear Cooperation actually says

The National Association of REALTORS® put the Clear Cooperation Policy in place in 2020. The rule is simple. Once a listing broker markets a home to the public, the home goes into the MLS so other agents and their buyers can see it too. Nationally, that means within one business day. A yard sign, a public website listing or a public email blast all count as public marketing. The goal is to keep the market open to every buyer.

Here in St. Louis, MARIS sets its own timing, and it is tighter. Under the MARIS notice that took effect April 22, 2026, a home that is publicly marketed, including with a social media post, must be entered in MARIS the same calendar day. A yard sign gets until the end of the next calendar day. If a home is not publicly marketed, the listing goes in within five business days of the signed listing contract.

What changed in 2025

In March 2025, NAR kept the policy and gave sellers more choices. A seller can now ask the listing agent to delay public marketing for a period. The home is still entered in the MLS where other agents can see it, but it is held back from the major listing websites during the delay. The seller signs a disclosure to show they understand the tradeoff, and each MLS decides how long the delay can last. You can read NAR's explanation in its March 2025 announcement.

The national policy does not ban Coming Soon listings or office exclusives, as long as the home is not marketed to the public. An office exclusive is a listing the brokerage keeps out of the MLS and does not advertise publicly, and the seller signs a disclosure to confirm they understand the tradeoff. How those options work in St. Louis depends on the MARIS rules in place at the time, so ask your agent which ones apply today.

Three ways to launch a St. Louis home

• Public from day one. The home goes on the MLS and the major websites right away, with photos, video and a full marketing push.
• A short pre-market window. The home is marketed as Coming Soon, or public marketing is delayed for a set period, before it goes fully public.
• Office exclusive. The brokerage shows the home to a limited audience and does not market it to the public. It is not in the MLS during this time, and the seller signs a disclosure.

What you gain and what you give up

An office exclusive or delayed launch can give you privacy, more control over who walks through your home and time to finish repairs or clear out the house. The tradeoff is that fewer buyers see the home early, which means fewer chances for buyers to compete for it. A public launch also tells you quickly what buyers think. A quiet one can leave you guessing.

How I approach it

Every home I list gets a custom marketing plan that goes well beyond professional photos and video, because I want the most buyers seeing your home when it matters most. If privacy or timing is a real concern, I will talk through a short pre-market window or an office exclusive, explain what it could cost you and put your decision in writing. It is your home and your call.

Questions to ask any agent before you choose

1. Who will see my home in the first two weeks, and where?
2. Will it appear on the major listing websites right away?
3. What is the plan if I do not get offers during the pre-market period?
4. Can I see the signed disclosure and the MLS rules that apply?

If you are buying

Ask your agent how they track Coming Soon homes in the MLS, since not every listing shows up on the major websites on day one.

Frequently asked questions

What is the Clear Cooperation Policy?

It is a National Association of REALTORS rule that requires a listing broker to enter a home in the MLS once it is marketed to the public. NAR sets the national standard at one business day, and the MARIS notice that took effect April 22, 2026 requires the same calendar day in St. Louis. NAR kept the policy in March 2025 and added a delayed marketing option for sellers.

Can I sell my St. Louis home before it goes on the MLS?

Only if the home is not marketed to the public. Under the MARIS notice that took effect April 22, 2026, a social media post or other public marketing means the home must be entered the same calendar day, and a yard sign gives until the end of the next calendar day. Coming Soon and office exclusive options depend on the current MARIS rules. The tradeoff is that fewer buyers see your home while it is held back.

Should I list my home publicly right away?

For most sellers, a public launch gets the most buyers looking at the same time. A private or delayed launch can make sense if privacy or timing matters more to you. Talk through your goals with your listing agent before you decide.
