If you own an apartment building in Los Angeles and you are thinking about selling, here is the reality: this is one of the most complex real estate transactions you will ever execute. The regulatory environment, the tax exposure, the buyer pool, and the RSO compliance requirements all make LA multifamily sales fundamentally different from selling a single-family home or a commercial building in most other cities.

This guide walks through what actually matters, in the right order, so you can go into the process prepared rather than figuring it out mid-escrow.

Step 1: Know What Your Building Is Worth Before Anyone Else Does

The first and most important move before listing is getting an accurate broker price opinion or formal appraisal. This is not optional, and it is not something you want to estimate from Zillow.

LA multifamily is priced on income, not aesthetics. Buyers are looking at your Gross Rent Multiplier, your net operating income, your cap rate relative to the submarket, and your rent-to-market ratio. A building with rents 30% below market in Koreatown gets underwritten completely differently from a stabilized building with the same unit count on the Westside.

Key metrics buyers use to value your building are covered in detail in our multifamily market analysis guide. Before you set a listing price, understand your GRM against the submarket median, your implied monthly rent per unit, and whether your rents are at market, above market, or significantly below.

One critical point many sellers miss: if your building is RSO-covered, buyers will price in the 4% annual increase cap taking effect July 1, 2026. If your rents are close to maximum allowable under RSO, that compresses the income upside story buyers can underwrite. If your rents are well below market, the upside story is there, but it is a slow story under the new cap formula.

Understand the new RSO formula and what it means for your NOI projections: RSO Rent Increase 2026.

Step 2: Get Your Documents and Compliance in Order

Buyers will ask for everything during due diligence, and surprises in escrow kill deals or force price reductions. The sellers who close cleanly have their documentation ready before the first showing.

Here is what you need to prepare before listing:

• Current rent roll with lease start dates, unit numbers, monthly rent, and RSO registration status
• 12 to 24 months of operating statements showing gross income, vacancy, operating expenses, and NOI
• Property tax records and current assessed value
• All active tenant notices, pay-or-quit notices, or eviction proceedings
• SB 721 balcony inspection compliance documentation if applicable to your building
• Any active code violations, permit issues, or deferred maintenance disclosures
• Mortgage payoff statement from your current lender if applicable
• Seismic retrofit compliance certificate if the building has undergone or is required to undergo retrofitting

SB 721 balcony inspection is one of the most commonly overlooked pre-sale compliance items in LA. See our full breakdown: SB 721 Balcony Inspection for Multifamily.

Step 3: Choose the Right Broker for This Specific Transaction

Not every real estate broker is equipped to sell a multifamily building in Los Angeles. The skills required are different from residential sales and different from general commercial brokerage.

A qualified LA multifamily broker should be able to:

• Provide a written broker price opinion based on income analysis, not comparable residential sales
• Identify the right buyer pool for your building type, whether that is 1031 exchange buyers, owner-users, value-add investors, or institutional capital
• Underwrite your building the way buyers will, not just present the best-case scenario
• Have a track record of closed transactions in your submarket, not just the broader LA market
• Coordinate with your CPA and qualified intermediary if a 1031 exchange is part of your exit

The broker you choose directly affects your final net proceeds. A broker who overprices to win the listing, then reduces the price after 60 days on market, costs you more than their commission saves.

Step 4: Understand the Full Cost of Sale Before You List

One of the most common mistakes LA multifamily sellers make is calculating their net proceeds from gross sale price without fully accounting for selling costs. Here is what a typical LA multifamily sale costs:

Measure ULA, passed by LA voters in 2022 and in effect since April 2023, adds a significant transfer tax to higher-value sales in the City of Los Angeles. If your building is within city limits and priced above $5M, model this into your net proceeds before you commit to a listing price.

Step 5: Plan Your Tax Strategy Before Closing, Not After

Capital gains tax on an LA multifamily sale is one of the highest combined rates in the country. California taxes capital gains as ordinary income at rates up to 13.3%. The federal long-term capital gains rate reaches 20% for high-income sellers. Add the 3.8% Net Investment Income Tax and depreciation recapture at 25%, and your combined exposure on a significant gain can approach or exceed 37%.

The two most common strategies LA multifamily sellers use to manage this exposure are:

• 1031 Exchange: Defer all capital gains by rolling proceeds into a like-kind replacement property within 45 days identification and 180 days closing windows. The exchange must be structured before your sale closes, and funds must flow through a qualified intermediary. Read our full guide:

• Installment Sale: Spread the gain recognition over multiple tax years by receiving payments over time. Less common but useful when a 1031 replacement property cannot be identified in time.

Work with a CPA before your listing goes live. Changing your tax strategy mid-escrow is expensive and sometimes impossible.

Step 6: Decide Between Open Market and Off-Market

This is one of the most debated questions among LA multifamily sellers. There is no universally correct answer, and the right choice depends on your specific building, your timeline, and your financial goals.
