How to Value an Apartment Building in Los Angeles

By Taylor Avakian
Valuing an LA apartment building requires analyzing current Cap Rates (averaging 4.5%-5.5%), Net Operating Income (NOI), and specific neighborhood rent multipliers. Factors like Rent Stabilization Ordinance (RSO) status can impact value by up to 20%.

Determining the Value of Multifamily Assets in LA

If you own an apartment building in Los Angeles, you know that standard residential comps don't apply. Commercial valuation is a mathematical formula driven by income, location, and potential.

The 3 Metrics That Matter

  1. Cap Rate (Capitalization Rate): This is your Net Operating Income (NOI) divided by the Price. In Los Angeles, buyers are currently looking for Cap Rates between 4.5% and 5.5% for stabilized assets.
  2. GRM (Gross Rent Multiplier): This is the Price divided by the Gross Scheduled Income. A typical GRM in high-demand areas like Silver Lake or West Hollywood hovers around 12x-15x.
  3. Price Per Door: While less technical, this is a quick metric. Class B units in LA often trade for $300k-$450k per door depending on the neighborhood.

The "Value-Add" Factor The biggest driver of value today is "upside." If your current rents are $1,500 but market rent is $2,500, buyers will pay a premium for the opportunity to renovate and re-tenant the building, even if the current cash flow is low.

Frequently Asked Questions

What is a good cap rate in Los Angeles?

Stabilized Class B apartment buildings in Los Angeles generally trade at cap rates between about 4.5% and 5.5%, and our H1 2026 market report puts the LA market cap rate at 5.2% (data through the first quarter of 2026). Coastal and luxury buildings trade lower, and value-add buildings in East and South LA higher.

How does rent control affect my building's value?

Los Angeles RSO (Rent Stabilization Ordinance) limits annual rent increases. Buildings with significant "loss-to-lease" (rents far below market) often sell at a lower immediate Cap Rate but a higher price-per-unit due to upside potential.

How do I calculate the cap rate on an LA apartment building?

Divide net operating income by the price. NOI is gross rent minus operating expenses such as property taxes, insurance, repairs and management, and it excludes the mortgage. Buyers of stabilized LA buildings are currently looking for cap rates between about 4.5% and 5.5%.

What is a typical GRM for an LA apartment building?

GRM is price divided by gross scheduled rent. In high-demand areas such as Silver Lake or West Hollywood it is often around 12 to 15 times. Because GRM ignores expenses, check it against the cap rate.

What is price per door?

Price per door is the sale price divided by the number of units. It is a quick check: Class B units in LA often trade for about $300,000 to $450,000 per door, depending on the neighborhood.

How does value-add upside affect price?

Buyers pay a premium where current rents sit well below market, for example $1,500 against a $2,500 market rent, because they can renovate and re-lease on turnover, even if current cash flow is low.
