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

April 22, 2025·2 min read

Understanding the key metrics investors use to evaluate Los Angeles apartment building investments.

Cap Rate: The Income-Based Snapshot

Capitalization rate ("cap rate") is:

NOI ÷ Purchase Price

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

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. Investors often look at GRM to quickly compare deals in the same submarket.

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
  • True out-of-pocket capital (down payment + closing + improvements)

How Investors Combine These Metrics in LA

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

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

A building with a slightly lower cap rate may still be attractive if it offers strong appreciation potential or a path to higher cash-on-cash after improvements.

What This Means for Owners

If you're planning to sell, knowing how investors underwrite helps you:

  • Understand feedback on pricing
  • Prioritize improvements that actually impact value
  • Present your rent roll and expenses in a way that builds buyer confidence

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 a higher return to compensate.
