How to Underwrite a CRE Bridge Loan

Underwrite a CRE bridge loan on the business plan and the exit. Size against as-is and stabilized value, test going-in and stabilized debt yield, cap loan-to-cost, and prove that the stabilized property can refinance into permanent debt. Sponsor execution history and a funded budget for capex and carry matter as much as current cash flow.

What makes cre bridge loan underwriting different

A bridge loan funds a commercial property that is not yet ready for permanent financing: a lease-up, a renovation, a recapitalization or a property with expiring tenants. The lender is underwriting a transition, not a stable rent stream, so current NOI is often too low to support the loan on its own. Value comes from executing the plan: renovating units, signing leases, raising rents. Risk comes from cost overruns, slow leasing, rising rates eating interest reserves, and an exit market that will not refinance the loan at maturity. The underwriter has to judge both the asset and the sponsor's ability to deliver.

A bridge lender wants to know the downside value of the collateral if the plan stalls, and whether the loan can be taken out at maturity by a permanent lender at conservative terms. It structures future funding, reserves and extension tests to control that path. The borrower's equity investors look at the same plan from the other side: projected IRR and equity multiple after the bridge costs, the leverage needed to hit return targets, and how much cushion exists before the deal needs fresh capital. Lenders get paid first and want the plan proven; equity gets paid only if it is.

Key metrics

Loan-to-cost (LTC)

Bridge loans fund acquisition plus capex, so leverage against total project cost shows how much sponsor cash is at risk ahead of the lender.

Bridge lenders commonly cap total LTC somewhere in the 70% to 85% range depending on asset type and sponsor.

As-is and stabilized LTV

As-is value is the lender's fallback if the plan fails, while stabilized value supports the exit refinance.

Lenders often look for stabilized LTV at or below roughly 65% to 75% so a permanent lender can take out the loan.

Stabilized debt yield

Projected stabilized NOI divided by the full loan amount tests whether the property will support takeout financing regardless of cap rate assumptions.

Many lenders want stabilized debt yields of roughly 8% or higher, varying by property type and rate environment.

Interest reserve coverage

In-place NOI often cannot cover floating-rate debt service during the transition, so the reserve must last until stabilization.

Reserves are commonly sized to cover debt service through the projected lease-up plus a cushion of several months.

Exit refinance DSCR

The loan is only as good as its takeout, so stabilized NOI is tested against permanent loan terms at a stressed rate.

Takeout lenders typically require DSCR of about 1.20x to 1.35x on the refinance.

Sponsor liquidity and net worth

Bridge plans frequently need additional equity for overruns or rate cap renewals, so sponsor capacity is part of the collateral.

Lenders often require sponsor net worth near the loan amount and liquidity of around 10% of it.

How to underwrite it, step by step

Review the business plan, renovation budget, leasing assumptions and timeline against the sponsor's track record on similar projects.
Underwrite in-place NOI from the T12 and rent roll, then build a monthly projection through stabilization.
Obtain an appraisal with both as-is and as-stabilized values and test them against recent sales and rent comparables.
Size the loan to the tightest of LTC, as-is LTV, stabilized LTV and stabilized debt yield constraints.
Size interest, capex and leasing reserves, and require a rate cap if the loan is floating rate.
Stress the exit by refinancing stabilized NOI at a higher permanent rate and a wider cap rate.
Set future funding conditions, extension tests, cash management triggers and guaranty terms in the term sheet.
Complete third-party reports and sponsor background checks before closing.

Key risks and mitigants

Renovation cost overruns or delays

Fund capex through a controlled future-funding draw process with inspections, retainage and a contingency line, and require completion guarantees from the sponsor.

Lease-up slower or rents lower than projected

Underwrite to market rents supported by comparables, size the interest reserve with cushion, and set extension tests on debt yield.

Rising floating rates exhausting reserves

Require an interest rate cap for the initial term with a replacement cap reserve, and test coverage at the cap strike.

No permanent takeout at maturity

Size to a conservative stabilized debt yield and LTV, include extension options with paydown and coverage tests, and stress exit cap rates.

Sponsor lacks capital to support the plan

Verify liquidity, require carve-out and completion guarantees, and set financial covenants on the guarantor.

Typical financing and deal structure

Bridge loans are usually floating-rate, interest-only senior mortgages with initial terms of two to three years and one or two extension options conditioned on debt yield or DSCR tests. A portion of the commitment is held back as future funding for capex and leasing costs, released against completed work. Lenders require a rate cap, interest and capex reserves, and cash management that springs on a performance trigger. Some bridge lenders split the loan into a senior note and a mezzanine or B-note to manage hold size, or finance their own position through a repurchase line or CRE CLO. Equity is often a syndicated joint venture between a sponsor and limited partners, sometimes with preferred equity filling a gap. Recourse is usually limited to bad-boy carve-outs plus a completion guaranty.

Red flags

Budget lacks contractor bids or a meaningful contingency
Projected rents well above any comparable in the submarket
Sponsor has no completed projects of similar scope or size
Stabilized debt yield that only works at an aggressive exit cap rate
Interest reserve that runs out before the projected stabilization date

Frequently asked questions

What is a typical debt yield for a bridge loan?

Bridge lenders look at two debt yields: going-in, on current NOI, which is often low because the property is in transition, and stabilized, on projected NOI after the business plan. Many lenders want a stabilized debt yield of roughly 8% or higher so a permanent lender can refinance the loan, though the threshold moves with property type, location and interest rates.

How is a bridge loan different from a construction loan?

A construction loan funds a ground-up building and is underwritten mostly on budget, completion risk and the stabilized value of something that does not exist yet. A bridge loan funds an existing, income-producing property that needs repositioning, leasing or time. Bridge lenders can underwrite in-place cash flow and as-is value, so they usually fund more at closing and rely less on draw schedules.

Are bridge loans recourse?

Most commercial bridge loans are non-recourse to the sponsor except for standard carve-outs covering fraud, misapplication of funds, voluntary bankruptcy and environmental issues. Lenders often add a completion guaranty for the renovation and sometimes a carry or interest guaranty. Smaller loans and less experienced sponsors may face partial or full recourse.

What happens if a bridge loan cannot be refinanced at maturity?

The borrower typically uses any remaining extension options, which usually require passing a debt yield or DSCR test and may require a principal paydown. If extensions are unavailable, the parties negotiate a modification, the sponsor injects equity, or the lender enforces through foreclosure or a deed in lieu. This is why underwriters stress the exit at origination.
