Bridge Loan in Commercial Real Estate

A bridge loan is short-term debt financing used to close a gap between when a commercial property is acquired or improvements begin and when long-term, lower-rate mortgage debt can be placed. Typically carrying rates 2 to 4 percentage points above prime, bridge loans are expensive but essential when timing, stabilization, or refinance conditions aren’t yet ready.

Why bridge loans exist

Commercial real estate deals often don’t align with traditional mortgage timing. A sponsor may acquire an office building that needs a two-year renovation before it stabilizes and qualifies for a permanent mortgage. A retailer exits a shopping center and the new owner must reposition tenants before Fannie Mae or a bank will lend. A trophy asset trades in a heated market, and the buyer needs capital immediately to close, but the securitization market won’t fund it for six weeks.

In each scenario, a bridge loan covers the gap. The borrower pays a premium (higher rate, higher fees) for speed and flexibility. The lender accepts shorter duration and refinance risk in exchange. It’s a trade-off: the borrower gets certainty of close; the lender gets paid to take on the odds that the refi market tightens or the property underperforms by exit.

Typical bridge loan structure

A bridge loan is usually floating-rate debt pegged to a benchmark (SOFR or LIBOR) plus a spread of 200–400 basis points. A property valued at £50 million might secure a £30 million bridge at SOFR + 300 bps (if SOFR is 5%, total cost is 8%). Monthly interest-only payments are standard, with the full principal due at maturity—no amortization.

Loan size is typically 65–75% of current asset value or 50–60% of post-stabilization appraised value, whichever is lower. The lender wants a cushion; if the property value drops 20%, the lender’s margin of safety shrinks. Bridge lenders often require significant equity from the sponsor (20–35% of purchase price) to align incentives and provide a loss-absorbing buffer.

Fees are substantial: origination fees of 1–2%, plus exit/prepayment fees of 1–3%. If the borrower refinances early, the lender is compensated for lost interest income via a prepayment penalty. Some loans include extension options (paying an additional fee) to push maturity out 6–12 months if the exit isn’t ready.

Common use cases

Acquisition before stabilization: A sponsor buys a multifamily complex with 60% occupancy. A traditional permanent lender won’t touch it until occupancy hits 85%+. A bridge loan covers the purchase price; the sponsor spends 18 months re-leasing and raising rents. Once stabilized, the sponsor refinances into permanent debt and repays the bridge.

Renovation and repositioning: A class-B office building is acquired for conversion to life sciences or common-area maintenance renovation. Hard costs and leasing timelines stretch beyond what a traditional lender will underwrite. A bridge loan funds the acquisition and carries the asset through the construction and lease-up period.

Acquisition timing mismatch: A seller needs to close in 60 days; a securitization or bank loan won’t close for 120 days. A bridge loan closes quickly, and the sponsor refinances to permanent debt once that permanent facility is ready.

Tenant transition: A major tenant vacates, and the property temporarily loses value. A bridge loan funds the acquisition at a discount; the new owner re-leases and refinances once the property re-stabilizes.

Bridge loan vs. mezzanine and preferred equity

Bridge loans are distinct from—but often paired with—mezzanine capital and preferred equity. A bridge lender holds a secured first or second lien on the property. If the deal fails and the property is sold, the bridge lender gets paid before equity holders but after any senior debt. A mezzanine or preferred investor typically has no security interest in the property itself; they hold an equity kicker or preferred return on the entity owning the property. If the deal underperforms, the mezzanine investor gets squeezed before the common equity partner but after all debt.

In practice, a deal might stack all three: a senior mortgage (60% LTV), a bridge loan (15% LTV), and mezzanine equity (25% equity). Each layer accepts a different risk profile and return requirement.

Refinance risk and exit strategy

The critical risk in a bridge loan is refinance risk. The borrower’s exit plan assumes they can refinance to permanent debt at a known rate and loan-to-value (LTV) once stabilized. If the property underperforms, refinance rates spike, or property values fall, that plan evaporates. The borrower must either inject more equity, negotiate an extension (paying an extension fee), or sell the property—often at a loss.

Bridge lenders mitigate this by stress-testing the exit: “If permanent rates are 150 bps higher, can you still refinance?” A borrower with a tight exit plan (relying on aggressive assumptions) faces extension risk and unexpected cash burn if refinance windows close.

Strong sponsors build in covenant buffers and maintain relationships with multiple permanent lenders so they have fallback options. Weak sponsors sometimes find themselves extending a bridge at a higher rate (another 100–150 bps), eating the cost and eroding equity returns.

Bridge loans in the market cycle

Bridge lending booms during acquisitions and construction phases, then tightens when recession looms and lenders lose appetite for refinance risk. After the 2008 crisis, bridge lending shrank for years. Post-COVID, as property values rebounded and transaction volumes surged, bridge lending exploded again. When permanent debt becomes scarce or expensive, bridge borrowers face tough choices: extend at higher rates, inject equity, or negotiate with preferred equity holders to restructure the capital stack.

Investor due diligence

When evaluating a CRE investment with bridge debt, investors scrutinize the waterfall distribution and the refinance assumptions. Key questions:

• Stabilization timeline: How long until the property is suitable for permanent debt?
• Permanent debt assumptions: What rate, LTV, and underwriting standards is the exit plan baked into?
• Sponsor track record: Has this team successfully exited bridge debt before?
• Extension cushion: Can the sponsor sustain another 12 months of bridge rates if the refinance is delayed?
• Sponsor equity: Is the equity cushion sufficient to absorb a 15–20% property value decline?

Bridge loans are a necessary tool for speeding acquisitions and managing timing gaps, but they’re an expensive crutch. Deals that rely on aggressive refinance assumptions and low sponsor equity often underperform.
