Selling a 20+ Unit Apartment Building in Los Angeles

Quick answer

Selling a 20+ unit apartment building in Los Angeles takes 90–150 days from listing to close. Pricing is driven by in-place net operating income and the spread between current and market rents, not by comparable sales per door alone. The buyer pool is institutional and syndicated capital using agency debt, so your rent roll, trailing-12 operating statements and rent-regulation status must be audit-ready before the property is marketed.

How large buildings are priced differently

Under 10 units, buyers underwrite mostly on price per unit and gross rent multiplier, because a single vacancy barely moves the return. At 20 units and above, the asset is priced off in-place net operating income capitalized at a market cap rate, then stress-tested against a stabilized pro forma. Two buildings on the same street with identical unit counts can trade 15–20% apart purely on the gap between contract rents and market rents.

That means the single highest-leverage thing an owner can do before selling a larger building is document income accurately: current rent roll with lease start dates, deposits held, RUBS or utility billbacks, laundry and parking income, and a clean trailing-12 operating statement that separates true operating expenses from capital items.

Who buys 20+ unit buildings in LA

The buyer pool changes completely once a building crosses roughly 16–20 units. Owner-users and first-time investors drop out; regional syndicators, family offices, 1031 exchange buyers trading up from smaller portfolios, and value-add funds take over. These buyers move on underwriting, not emotion, and they will walk from a deal where the numbers cannot be verified.

Regional syndicators raising equity per deal — need a 60–90 day close and an assumable or newly sourced agency loan.
Family offices holding for 10+ years — pay closest to full price for clean, well-located, low-turnover assets.
1031 exchange buyers under a 45-day identification clock — the most price-tolerant pool, but only if the timeline fits.
Value-add funds targeting under-market rents — pay on the spread they can capture, not on in-place income.

Rent regulation is the first diligence question

For LA County buildings, the first question every institutional buyer asks is which rent regime applies. City of LA RSO buildings (generally built before October 1978) carry annual allowable increase caps and just-cause eviction requirements. Everything else in California falls under AB 1482 unless exempt. Santa Monica, Culver City, Long Beach, Inglewood and several other cities layer their own ordinances on top.

Get this documented up front. A seller who can hand a buyer a unit-by-unit regulation and rent-history summary on day one closes faster and at a higher price than one who lets the buyer discover surprises in escrow. Always verify the specific rules for the specific property with the governing city before relying on any general summary.

Marketing and timeline

A larger building is marketed with a full offering memorandum, a broker-verified rent roll, a T-12, a capital-expenditure history and unit-level photos. Expect 21–30 days of marketing, a call for offers, a best-and-final round with the top two or three buyers, then 15–21 days of due diligence and 30–60 days for loan funding.

Total: 90–150 days from listing to recorded sale. Deals with assumable agency debt or an all-cash buyer can close faster; deals requiring new agency loans, seismic retrofit clearance or estate and partnership approvals run longer.

Frequently asked questions

How long does it take to sell a 20-unit apartment building in Los Angeles?

Typically 90–150 days from listing to recorded sale: 21–30 days of marketing, 15–21 days of due diligence, and 30–60 days for the buyer's agency or bank loan to fund. All-cash or loan-assumption deals can close in 45–60 days.

What documents do I need before listing a large apartment building?

A current rent roll with lease dates and deposits, trailing-12 operating statements, the last two years of tax returns or a Schedule E for the property, a capital-expenditure history, utility bills, service contracts, and rent-regulation documentation including rent-increase history for each unit.

Do larger buildings sell at higher or lower cap rates than duplexes?

Generally higher cap rates, which means a lower price per unit. Small 2–4 unit buildings benefit from residential financing and owner-user demand that compresses cap rates; 20+ unit buildings are priced on income by professional buyers. Across tracked closings the median price per unit falls steadily from the 2–4 unit band to the 20+ unit band.

Should I fix vacancies before selling?

It depends on the buyer pool you are targeting. A value-add buyer will pay for the upside of vacant, renovatable units. A family office or agency-financed buyer needs occupancy for debt sizing. Decide the target buyer before spending renovation dollars.
