You closed on a commercial property with a bridge loan, and right now the building sits empty. The bridge maturity date is approaching, and you need a permanent financing solution. The short answer is yes, you can refinance a bridge loan into a long-term commercial mortgage—even on a currently vacant property—but you will need to clear several hurdles that conventional lenders put in front of borrowers who lack in-place rental income.
This guide walks you through every step: why vacancy matters to lenders, exactly what you need to do before applying for permanent financing, and the alternative paths available if full stabilization is not yet realistic.
Bridge loans are designed for transitional situations. They give investors short-term capital to acquire, renovate, or reposition a commercial asset before locking in long-term debt. As one industry source explains, bridge financing "offers borrowers an opportunity to stabilize an asset by either rehabbing vacant units, increasing occupancy levels or executing an adaptive re-use business plan." The expectation is always that you will exit the bridge within its term.
Key characteristics of bridge loans include:
Conventional long-term lenders—banks, CMBS conduits, life-insurance companies—underwrite primarily on cash flow. A vacant property generates zero income, which means the debt-service coverage ratio (DSCR) is effectively 0.00x. Most permanent lenders require a minimum DSCR of 1.20x to 1.25x before they will approve a refinance.
Beyond the DSCR shortfall, vacancy introduces additional concerns:
The exit strategy should be in place before you ever sign the bridge loan documents. Bridge lenders place a strong emphasis on the exit strategy at maturity. Your plan should detail target rents, leasing timelines, renovation budgets, and the permanent lender type you intend to use.
Many bridge loans can be structured to include reserves for the capital improvements typically required to attract new tenants. Use these funds strategically: upgrade common areas, install modern HVAC, refresh the building envelope. Every improvement you make should have a measurable impact on achievable market rents.
Do not wait for renovations to finish before marketing the space. Signed leases—even with future commencement dates—dramatically improve your refinancing position. Permanent lenders will often underwrite on executed leases with move-in dates within 60–90 days of closing.
Target at least 75%–80% economic occupancy before approaching a permanent lender. At that level, most well-located properties will clear the 1.20x DSCR bar. CMBS underwriters may also look at the stabilized income the property will generate once fully leased.
The permanent lender will order its own appraisal, but having a recent independent valuation gives you negotiating leverage and helps you shop loan quotes accurately. Make sure the appraiser accounts for all newly signed leases.
Your permanent financing options include:
| Loan Type | Typical LTV | Term | Best For |
|---|---|---|---|
| CMBS Conduit | Up to 75% | 5, 7, or 10 years | Stabilized income-producing assets |
| Bank Portfolio | Up to 70% | 5–10 years (balloon) | Borrowers with strong bank relationships |
| Life-Insurance Company | Up to 65% | 10–25 years | Low-leverage, high-quality properties |
| SBA 504 | Up to 90% | 10, 20, or 25 years | Owner-occupied commercial properties |
Some bridge lenders waive the prepayment penalty entirely if you refinance into their affiliated permanent CMBS conduit program, saving you roughly 1% of the outstanding balance.
Coordinate closing dates carefully. Most bridge loans do not have extension options without additional fees. Build in at least 30 days of cushion between your expected permanent-loan closing and the bridge maturity date.
Sometimes lease-up takes longer than expected. If your bridge is maturing and the property is still substantially vacant, you have several fallback options:
Imagine you purchased a 40,000-square-foot suburban office building for $3.5 million using a bridge loan at 65% LTV ($2.275 million). The building was completely vacant at closing. Over the next 14 months you invested $400,000 in renovations and signed leases totaling 30,000 square feet at $18 per square foot, generating $540,000 in gross annual rent. After operating expenses, net operating income (NOI) reached $360,000.
You approach a CMBS conduit lender for a $2.5 million permanent loan at a 6.5% rate on a 10-year term with 30-year amortization. The annual debt service is approximately $189,500. Your DSCR is $360,000 ÷ $189,500 = 1.90x—well above the 1.25x minimum. The lender approves the deal, you pay off the bridge, and you lock in stable financing for a decade.
Yes, but with conditions. Permanent lenders underwrite on cash flow, so you will typically need to lease the property to a level that supports a minimum 1.20x DSCR before you qualify. Some niche lenders or portfolio lenders may consider a lower threshold if the property is in a strong market and you have significant equity.
Most CMBS and bank lenders target a minimum DSCR of 1.20x to 1.25x on in-place income. During the bridge phase, underwriting may accept a 1.0x DSCR on existing income while the property is being stabilized.
Bridge loans typically last 12 to 36 months. Many investors set an internal goal of achieving stabilization within 18 months, leaving a buffer before the maturity date. Extensions are often available but add cost.
The most common take-out loans include CMBS conduit loans, bank portfolio loans, life-insurance-company loans, and SBA 504 loans. The right choice depends on your LTV, property type, occupancy level, and whether you are an owner-occupant or investor.
That depends on the lender and loan structure. Some bridge lenders waive the prepayment penalty if you refinance into their permanent loan program. Otherwise, the typical prepayment penalty is around 1% of the outstanding loan balance.
It is extremely difficult. A fully vacant building with zero income will not meet the DSCR requirements of most conventional lenders. In rare cases, an owner-occupant planning to use the space for their own business may qualify through an SBA 504 loan or a bank portfolio product that considers the borrower's overall financial strength rather than just property cash flow.
