Apartment Building Valuation · Los Angeles
A Los Angeles apartment building is valued primarily on the income it produces, using three methods that buyers apply together: the income approach, which divides net operating income by a market cap rate; the gross rent multiplier, which prices the building as a multiple of annual gross rent; and the sales comparison approach, which measures price per unit against recent comparable trades. In Los Angeles, one additional factor moves value more than any other: the gap between what your units currently rent for and what they would rent for at market. The Group CRE has closed more than $488 million in LA multifamily and prepares broker opinions of value at no cost.
The Math
The income approach is the one that governs. Take your net operating income, which is gross rental income minus all operating expenses but before debt service and depreciation, and divide it by the market cap rate for your submarket and building type. A building producing $300,000 in NOI at a 5.25 percent cap rate is worth roughly $5.7 million. Because this is division, small changes matter enormously: at a 5.75 percent cap rate that same building is worth about $5.2 million. A half-point move in cap rate is a half-million dollars.
The gross rent multiplier is the quick screen. Divide the sale price by annual gross rent. LA multifamily GRMs commonly run in the 11 to 16 range depending on submarket and condition. GRM ignores expenses, so it is a sanity check rather than a valuation, but it is how many buyers filter deals before they underwrite them.
The sales comparison approach anchors everything to reality. What have similar buildings actually traded for, on a price-per-unit and price-per-square-foot basis, in the last six to twelve months within a few blocks? Metro-wide LA price per unit has been running in the range of roughly $280,000 to $312,000 in 2026 depending on the data source, but submarket variation is wide, and the comparable set matters far more than the metro average.
The LA Variable
This is where generic valuation advice fails Los Angeles owners. A building with rents 40 percent below market is worth less today on current income, and worth more to the right buyer on future income. Which of those two numbers you actually receive depends entirely on how the rent gap is documented and presented.
Most pre-1978 buildings in the City of Los Angeles fall under the Rent Stabilization Ordinance, which caps annual increases and limits how quickly rents can reset. Buildings built after February 1995 that fall outside local rent control are still generally subject to AB 1482 statewide caps. Santa Monica, Beverly Hills, West Hollywood, Culver City, and Inglewood each run their own frameworks with different rules.
Buyers underwrite that regulatory exposure directly into their offer. Two identical buildings on the same street, one with long-tenured RSO tenancies and one with recent turnover at market rents, can differ by 15 to 25 percent in value. A rent roll analysis showing unit-by-unit current rent against market rent, with a realistic timeline for capturing the difference, is the single most valuable document in the marketing package, because it converts a discount into a growth story.
If your building is in the City of Los Angeles and likely to sell above $5.4 million, Measure ULA also affects your net rather than your value. Full detail is in our LA Multifamily Regulatory Guide.
Quick Reference
Market-level figures for orientation. Your building's actual value depends on its submarket, unit mix, condition, and rent gap, which is what a broker opinion of value is for.
Metric | Current LA range |
|---|---|
Cap rate, mid-tier assets | Roughly 4.5% to 5.8%, varying by submarket, size, and rent upside |
Gross rent multiplier | Commonly 11 to 16 |
Price per unit, metro average | Roughly $280,000 to $312,000 in 2026; Westside submarkets trade well above this |
Vacancy | Approximately 5.5% to 5.6% |
Rent-control discount | 15% to 25% between comparable buildings with and without deep below-market tenancies |
Measure ULA (City of LA only) | 4% above $5.4M; 5.5% at $10.9M+ for closings after June 30, 2026, from the first dollar |
Choosing an Approach
A broker opinion of value is a market-based estimate prepared by a broker actively trading in your submarket. It reflects what buyers are paying right now, including the off-market trades that never hit public records. It is typically provided at no cost, turns around in days, and is the right tool when you are deciding whether to sell, testing a price, or planning a 1031 exchange.
An appraisal is a formal valuation by a licensed appraiser, usually ordered by a lender. It follows regulated methodology, costs money, takes weeks, and is what you need for financing, estate and tax purposes, litigation, or partnership disputes. Appraisals are often more conservative because they lean on closed comparable sales, which lag the live market in a moving cycle.
Automated online estimates are a distant third for multifamily. They are built on residential models that cannot see your rent roll, your expense structure, or your RSO exposure, which are the three things that actually determine the value of an LA apartment building.
For most owners weighing a sale, start with a broker opinion of value. It costs nothing and it answers the real question, which is what a buyer would pay this quarter.
Taylor Avakian will prepare a broker opinion of value for your building: current market value, the rent gap analysis, the Measure ULA math if it applies, and what comparable buildings in your submarket are trading at right now. No cost and no obligation.
Common Questions
How do I calculate the value of my apartment building?
Divide your net operating income by the market cap rate for your submarket. NOI is gross rental income minus operating expenses, before debt service and depreciation. A building with $300,000 in NOI at a 5.25 percent cap rate values at roughly $5.7 million. Cross-check that figure against recent price-per-unit comparables nearby and against a gross rent multiplier in the 11 to 16 range typical for Los Angeles.
What cap rate should I use to value my LA building?
Mid-tier Los Angeles multifamily has generally been trading in the 4.5 to 5.8 percent range in 2026, with the metro average around 5.8 percent in the second quarter, up about 30 basis points year over year. Westside and coastal submarkets trade at lower cap rates, meaning higher prices per dollar of income. Buildings with significant below-market rents often trade at lower going-in cap rates because buyers are pricing the future income, not the current income.
Does rent control lower the value of my building?
It lowers value based on current income, because regulated rents cap what the building produces today. But buildings with deep below-market rents attract value-add buyers who price the upside, so the discount is smaller than owners often fear when the rent gap is properly documented. Comparable buildings with and without deep below-market tenancies commonly differ by 15 to 25 percent. A unit-by-unit rent roll analysis showing current versus market rent is the most effective way to protect value.
Is a broker opinion of value the same as an appraisal?
No. A broker opinion of value is a market-based estimate from a broker actively trading in your submarket, usually free and delivered within days, reflecting what buyers are paying right now. An appraisal is a formal valuation by a licensed appraiser, typically ordered by a lender, that costs money, takes weeks, and is required for financing, estate, tax, or litigation purposes. Appraisals tend to be more conservative because they rely on closed sales that lag the live market.
How much is my building worth per unit in Los Angeles?
Metro-wide price per unit has been running roughly $280,000 to $312,000 in 2026 depending on the data source, with the second quarter average around $280,600, up about 3.3 percent year over year. Submarket variation is large. Westside and coastal properties trade well above the metro average while South LA and parts of the Valley trade below it. Price per unit is a useful cross-check but should never be the primary valuation method, because it ignores unit mix, size, condition, and rent levels.
Does Measure ULA reduce my building's value?
ULA does not change your building's market value, but it reduces what you net at closing. For closings after June 30, 2026, the City of Los Angeles applies a 4 percent transfer tax above $5.4 million and 5.5 percent at or above $10.9 million, calculated from the first dollar of the sale price. On a $6 million sale that is roughly $240,000 in ULA alone. Buildings priced just above a threshold deserve careful pricing analysis. Properties outside City of Los Angeles boundaries are not subject to ULA.
How often should I get my building valued?
Annually is reasonable for most owners, and more often if you are considering a sale, refinance, or 1031 exchange, or if your submarket is moving quickly. Values shift with cap rates and interest rates even when your income has not changed, so a valuation from two years ago may be materially wrong today. Regular valuations also make estate planning and partnership decisions considerably easier.
What documents do you need to value my building?
A current rent roll with unit mix, current rents, and tenancy start dates, plus trailing twelve months of operating expenses. Those two documents allow a reliable opinion of value. Helpful additions include recent capital improvements, the property tax bill, existing loan terms, and any RSO registration details. If you do not have all of it organized, that is not an obstacle. We can work from a rent roll and fill gaps from public records.
