Listing an Apartment BuildingA guide by Shaya Lowenstein, Lyon Stahl Investment Real Estate Call (323) 944-2221

For owners choosing who will sell their apartment building

Selling an apartment building off-market or on the open market

An open-market sale tests your price against every buyer the broker can reach, and an off-market sale trades some of that competition for privacy. MLS rules, including NAR's 2025 changes, shape how a quiet sale can run, so settle the approach and its guardrails in the listing agreement.

  • An open-market sale shows the building to every buyer the broker can reach. An off-market sale shows it privately to buyers the broker selects.
  • Exposure sets price through competition. Privacy protects tenants, timing and confidential circumstances. You are choosing which one matters more for this building.
  • MLS rules shape the choice. NAR kept its Clear Cooperation Policy in 2025 and added delayed marketing and office exclusive options that need your signed disclosure, and each MLS applies its own version.
  • A quiet sale needs guardrails: a written price opinion, clear dual agency terms, and a date to go public if the offers fall short.

Selling your apartment building off-market or on the open market comes down to what you value more, competition among buyers or privacy and control. Neither is right by default. The MLS rules in force in 2026 also shape how a quiet sale can be run, so settle the approach in the listing agreement.

What off-market and open-market mean

An open-market listing is marketed publicly. The broker puts it in the MLS and other listing services, sends it to buyers and to the brokers who represent them, and may set a deadline for offers, with the aim of getting every plausible buyer looking at once.

An off-market sale, also called a quiet sale or a pocket listing, is offered privately. The broker takes it to a limited group, under confidentiality agreements if you want them, and the building never appears on a public website. In MLS terms it may be an office exclusive listing, which NAR's policy describes as one the seller has directed not be disseminated through the MLS and not be marketed to the public.

Between the two sit hybrids. A listing can be entered in an MLS for cooperation among brokers while held back from public sites for a period, and a sale can start quietly and then go wide on a set date.

What the MLS rules say, as of 2026

These rules come from NAR and the MLSs rather than from state law, and they bind brokers through their MLS participation. As NAR's policy pages describe them at the time of writing:

  • Under the Clear Cooperation Policy, a listing broker who markets a property to the public has one business day to submit the listing to the MLS. One-to-one communications between brokers do not trigger it.
  • In March 2025, NAR kept that policy and added Multiple Listing Options for Sellers. It lets a seller delay public marketing through IDX and syndication for a period each MLS sets, with the listing still filed in the MLS for other brokers. MLSs had until September 30, 2025 to implement it.
  • A seller who chooses a delayed marketing listing or an office exclusive signs a disclosure giving informed consent to give up the benefits of immediate public marketing.
  • Since August 17, 2024, under NAR's settlement rules, offers of compensation to buyers' brokers cannot appear on the MLS, though a seller can still make one through other channels.

Each MLS writes its own version, and they differ. CRMLS said in 2025 that it would not adopt the delayed marketing option. It pointed brokers instead to its Coming Soon status, which puts a listing in the MLS for cooperation for up to 21 days while the property is prepared for showings, and to office-level opt-outs from IDX and syndication. Whether a given rule reaches your building can also depend on the property type and the MLS, so ask your broker which MLS the listing would go into and what its rules allow today, and get the answer in writing.

When a quiet sale can make sense

  • The tenants would be badly disrupted by a stream of tours, or news of a sale would unsettle them.
  • The circumstances are private, such as a divorce, a partnership breaking up, or a family disagreement over an inherited building.
  • The likely buyer pool is small and known, such as the owner next door or investors already active on the street.
  • You plan to test the price with a few serious buyers before deciding whether to go public.

Shaya handles both kinds of listing, open-market sales and quiet ones to buyers he brings in, and he never buys the building himself. The quiet route still starts where an open listing does, with a price opinion you can check and a listing agreement you have read.

When full exposure is worth it

Go wide when price is what you care about most and the building would appeal to many kinds of buyer. Competing offers show you what the market will pay, which a private sale cannot, and they give you bargaining power on terms such as the deposit, the inspection period and the closing date. If you hold the building with others, as a co-owner, a partner or a trustee, a documented market test may matter for reasons beyond price, and your attorney can tell you whether it does.

Protecting yourself in a quiet sale

  1. Get a written price opinion before the first buyer sees the building, so every offer has a benchmark.
  2. Ask the broker to tell you, in writing, which buyers were approached and what each said.
  3. Settle dual agency in the listing agreement. California's definition in Civil Code section 2079.13 covers an agent acting for both sides directly or through a salesperson or broker associate, and section 2079.21 bars a dual agent from telling the buyer your confidential information, such as a willingness to accept less, without your express permission.
  4. Read and keep a copy of any MLS disclosure you sign.
  5. Set a date. If the quiet offers do not reach your number by then, the building goes to the open market.

Write all of it into the listing agreement, including how and when the switch to the open market happens. Shaya can run either kind of sale, but he is not an attorney, and the wording of those terms is a job for a real estate attorney before you sign.

Questions about listing

What is an off-market sale of an apartment building?

It is a sale the broker offers privately to buyers they select, without a public listing or a website. In MLS terms that can be an office exclusive, and under NAR's 2025 policy you would sign a disclosure to set one up.

Will I get a lower price if I sell off-market?

You might not, but the price gets tested against fewer offers, because fewer buyers see the building. Protect yourself with a written price opinion before the first showing and a date to go public if the quiet offers fall short.

What is the Clear Cooperation Policy?

It is NAR's rule that once a listing broker markets a property to the public, the listing has to go into the MLS within one business day. NAR kept it in 2025, added options that need the seller's signed disclosure, and left each MLS to apply its own version.

Can one broker represent both me and the buyer in a quiet sale?

Yes, but only with the knowledge and consent of both you and the buyer, which is the condition California's disclosure form sets, and two agents from one brokerage on opposite sides make that brokerage a dual agent. A dual agent cannot share your confidential information, like a willingness to take less, unless you expressly allow it, and the listing agreement can set terms for dual agency or refuse it.

Can I start with a quiet sale and list publicly later?

Yes, and the listing agreement is where to plan it. Once the broker markets the building to the public, the Clear Cooperation Policy gives one business day to get it into the MLS, so decide in advance when and how the switch happens.
