Short answer: Selling an apartment building in Los Angeles takes roughly 60–120 days from listing to close and follows eight steps: (1) trailing-12 underwriting and broker valuation, (2) decide on-market vs. off-market, (3) prepare a professional Offering Memorandum, (4) launch a targeted marketing campaign to LA multifamily investors, (5) call for offers and select a buyer based on price and certainty of close, (6) negotiate the PSA and open escrow, (7) navigate due diligence, estoppels, and the LA RSO 9-A disclosure, and (8) close — often into a 1031 replacement property. The single biggest determinants of net proceeds are accurate pricing, OM quality, and which broker's buyer list the deal touches first.
Step 1 — Get an honest valuation before you list
Most LA apartment owners over- or under-price by 8–15% because they anchor to a neighbor's headline price instead of a trailing-12 underwrite. A defensible valuation triangulates three methods: income (T-12 NOI ÷ submarket cap rate), sales comps (price-per-unit and price-per-square-foot of buildings that actually closed in the last 6 months), and replacement cost. For rent-controlled LA buildings, loss-to-lease and the realistic timeline to mark units to market are the swing variables — a buyer underwrites these explicitly, and so should you.

Step 2 — Decide: on-market or off-market?
On-market (CoStar, LoopNet, broker email blasts, signage) typically produces the highest price because it creates competition. Off-market trades privacy and speed for ~3–7% in price discovery. Choose off-market when (a) tenants would be disrupted by tours, (b) you have a partnership or estate situation, or (c) a known buyer's list will clear the price you need. Most South Bay and Long Beach owners net the most on a tightly run on-market process with a 21-day call-for-offers.
Step 3 — Build a professional Offering Memorandum (OM)
The OM is the single document a buyer underwrites from. A weak OM costs you offers. A strong LA multifamily OM includes: rent roll with lease dates and last-rent-increase dates, T-12 operating statement, capital expenditure history, photos shot at golden hour, comps grid, financing assumptions, rent control status of each unit, and — critically — a clear value-add narrative. See active Samimi CRE Advisors listings for the OM standard buyers now expect in LA.
Step 4 — Marketing: where LA multifamily buyers actually look
The buyer pool for a 5–30 unit LA apartment building is approximately 2,500–4,000 active investors. Reaching them requires more than a LoopNet flyer. A real campaign hits: (1) CoStar/LoopNet, (2) the broker's proprietary buyer database, (3) the top 25 LA multifamily brokers' personal networks, (4) 1031 buyers in feasibility windows, (5) family office and syndicator lists, and (6) targeted email to owners of comparable buildings in your submarket. Most listings die because they only get steps 1–2.
Step 5 — Call for offers, then choose for certainty
The highest offer is rarely the best offer. Score every offer on five factors: price, earnest money (1–3% is standard in LA, hard day-one signals strength), financing contingency length, due diligence period (21–30 days is typical), and the buyer's last three closings. A retrade-prone buyer at $5.1M nets less than a clean buyer at $4.95M.
Step 6 — Negotiate the PSA and open escrow
The Purchase & Sale Agreement should specify: deposit schedule, contingency timelines, prorations (rent, security deposits, property tax), seller representations limited to actual knowledge, and — for LA buildings — explicit allocation of any pending RSO or code-enforcement matters. Use an escrow officer who has closed at least 50 LA multifamily deals; the learning curve on RSO transfer is real.
Step 7 — Due diligence, estoppels, and LA-specific disclosures
Three LA items trip up first-time multifamily sellers: tenant estoppels (every tenant signs a one-page confirmation of rent and deposit), LA RSO 9-A disclosure (required for City of LA rent-stabilized buildings transferring ownership — verify the current form for your specific property), and Section 1102 transfer disclosures. Buyers also order a Phase 1, roof report, sewer scope, and unit-by-unit inspections — plan for 7–10 days of access.
Step 8 — Close, then 1031 (if applicable)
Wire funds typically arrive 1–2 business days after recording. If you're doing a 1031 exchange, your Qualified Intermediary must be in place before closing, you have 45 days from close to identify replacement property, and 180 days total to close on it. Most sellers under-budget for the identification window — start replacement-property tours 30 days before your sale closes, not after.

Frequently asked questions
How long does it take to sell an apartment building in Los Angeles?
60–120 days from listing to close is typical for a well-priced LA apartment building. Marketing runs 21–30 days, due diligence 21–30 days, and closing 30–45 days after contract.
What are closing costs for an LA apartment seller?
Plan for roughly 5–6% of sale price: broker commission (typically 4–5% total, often split with the buyer's broker), LA City and County transfer taxes (Measure ULA applies above $5.15M as of the most recent threshold — verify current rates with escrow), title and escrow fees, and prorations.
Do I have to pay capital gains tax?
Not if you reinvest into like-kind real estate through a 1031 exchange that meets the 45-day identification and 180-day closing windows. Talk to your CPA before you list — the structure matters.
What if my building is rent-controlled?
LA RSO and AB 1482 buildings sell every day — buyers underwrite the regulated rents and price accordingly. Loss-to-lease, allowable annual increases, and the realistic vacancy turnover timeline drive the buyer's math. The right broker frames the upside without overstating it.
