The San Diego multifamily lending market has entered a new phase in 2026.

After years of low interest rates, aggressive underwriting, and strong rent growth, lenders are now sizing loans far more conservatively — especially in regulated California markets like San Diego.

Multifamily remains one of the strongest long-term asset classes.
But the rules around refinancing and acquisition financing have shifted — quietly, but meaningfully.

If you own 5+ unit property in San Diego, here’s what changed.

Lenders Are Prioritizing Durable In-Place Cash Flow

In previous cycles, lenders often underwrote to:

• Projected rent growth

• “Market rent upside”

• Pro forma renovations

• Future NOI increases

In 2026, underwriting has tightened.

Lenders are focusing on:

• In-place net operating income (NOI)

• Conservative rent growth assumptions

• Higher operating expense projections

• Stress-tested debt coverage ratios (DSCR)

For San Diego apartment owners, this means loan proceeds are now heavily tied to what your building produces today — not what it could produce.

Discounted Cash Flow (DCF) Is Replacing Optimism

More lenders are relying on discounted cash flow (DCF) analysis to size loans.

DCF modeling evaluates:

• Future rent growth under conservative assumptions

• Rising insurance costs

• Increasing labor and maintenance expenses

• California rent control limitations

Instead of assuming rents will “catch up,” lenders want proof that your asset can sustain performance even if rent growth slows.

In a market like San Diego, where operating expenses have risen sharply, this materially impacts valuation and refinance proceeds.

Refinancing in San Diego May Be Riskier Than Buying

One of the biggest surprises for apartment owners in 2026:

Refinance proceeds are often lower than expected.

We’re seeing:

• Tighter DSCR requirements (often 1.25+)

• Higher interest rate stress tests

• Reduced leverage on older Class B/C assets

• More scrutiny on rent-controlled properties

Owners who refinanced in 2020–2022 at peak valuations may now face:

• Equity trapped in the deal

• Cash-in refinances

• Reduced supplemental loan availability

Ironically, well-capitalized buyers today may have an easier time structuring new acquisitions than some owners have refinancing legacy debt.

California Rent Control Is Affecting Loan Sizing

California’s statewide rent control (AB 1482), combined with local tenant protections in San Diego, has created a more cautious underwriting environment.

Lenders now evaluate:

• Rent increase limitations

• Tenant stability and turnover patterns

• Relocation cost exposure

• Operating expense volatility

For stabilized assets with long-term tenants, the rent growth runway may be limited — and lenders are underwriting accordingly.

This doesn’t make multifamily weak.

It simply means the underwriting math is different than it was three years ago.

The San Diego Market Is Splitting

Performance across multifamily assets is no longer uniform.

Broadly speaking:

• Well-operated, renovated properties in strong submarkets are still producing solid NOI growth.

• Properties with deferred improvements, heavy expense creep, or aggressive leverage are under pressure.

Asset quality and operational discipline now matter more than ever.

San Diego remains fundamentally supply-constrained — which supports long-term demand — but lenders are differentiating sharply between strong and average deals.

What Lenders Want to See in 2026

If you are seeking multifamily financing in San Diego, expect lenders to prioritize:

Strong in-place cash flow
Conservative leverage
Clean financials and trailing-12 documentation
Realistic expense ratios
Clear operational strategy
Limited reliance on aggressive rent growth

Deals that pencil today are built on durability — not projections.

The Big Takeaway for San Diego Apartment Owners

Multifamily in San Diego isn’t broken.

But it is no longer forgiving.

The investors who win in 2026 are the ones who:

• Understand how lenders are underwriting today

• Evaluate refinance risk early

• Model conservative scenarios

• Protect equity instead of over-leveraging

Before refinancing, improving, or selling, it’s critical to understand:

• What your property would qualify for in today’s lending environment

• What it could achieve at stabilized market rents

• How expense adjustments affect loan sizing

• Whether holding, improving, or selling creates the strongest outcome
