Cap Rates, GRM & Cash-on-Cash: How Los Angeles Multifamily Investors Underwrite Deals

· 2 min read

Understanding cap rate, GRM, and cash-on-cash returns is essential for evaluating LA multifamily investments. These metrics help investors compare properties and underwrite deals effectively.

Cap Rate: The Income-Based Snapshot

Understanding cap rate, GRM, and cash-on-cash starts with the basics. Capitalization rate (“cap rate”) is: NOI ÷ Purchase Price

In LA today, many multifamily deals trade in the 4.5–5.5% cap rate range, depending on location, condition, and rent control status.

Investors use cap rate to:

  • Compare different properties on an income basis
  • Gauge whether a building is priced aggressively or conservatively
  • Evaluate how property income compares to other investments

GRM: Quick Rule-of-Thumb Valuation

Gross Rent Multiplier (GRM) is: Price ÷ Gross Scheduled Income

For example, a building that collects $200,000/year in scheduled rent and sells for $3,400,000 is a 17.0 GRM.

Cash-on-Cash Return: What You Actually Take Home

Cash-on-cash focuses on the return on your actual cash invested, after financing:

(Annual Pre-Tax Cash Flow) ÷ (Total Cash Invested)

This metric is critical for leveraged investors because it reflects loan terms, debt service, and true out-of-pocket capital.

How Investors Combine These Metrics

Savvy buyers don’t rely on just one metric. Typical underwriting includes:

  • Target cap rate and GRM within submarket norms
  • Target cash-on-cash return that justifies the leverage and risk
  • Stress tests for vacancy, rent growth, and interest rate changes

Request a valuation to see how your building stacks up.

Quick FAQs

Q: Is a higher cap rate always better?
A: Not necessarily. Higher cap rates can reflect higher risk, weaker locations, or significant deferred maintenance.

Q: How do interest rates affect cap rates?
A: When debt becomes more expensive, cap rates tend to rise as buyers demand higher returns.
