The decision is rarely "which is cheaper", it's "which one matches the deal."
Wrong structure on the right deal is a common, expensive mistake. Permanent debt on a value-add property leaves loan proceeds on the table and locks in defeasance penalties when you sell at year three. Bridge debt on a stabilized hold burns 200 to 300 basis points of unnecessary spread for the privilege of an option you don't need. Picking right starts with the deal, not the loan.
The two products in one paragraph each
Bridge debt is short-term (12 to 36 months), almost always floating-rate, almost always interest-only, designed for properties in transition: value-add repositioning, lease-up, time-sensitive acquisitions, or maturing loans on assets six to twelve months away from qualifying for permanent debt.
Permanent financing is long-term (5 to 10+ years), usually fixed-rate, with 25- or 30-year amortization, designed for stabilized assets producing predictable cash flow. Lower rate, higher prepayment friction, and a structure built for a multi-year hold.
Side-by-side
| Feature | Bridge | Permanent |
|---|---|---|
| Term | 12 to 36 months + extensions | 5 to 10+ years |
| Rate | Often floating, priced against SOFR plus lender pricing | Often fixed, priced against a market benchmark plus lender pricing |
| Amortization | Interest-only | 25 to 30 year amort, balloon at maturity |
| Max LTV | Up to 75 to 80% | 60 to 75% |
| Recourse | Mostly non-recourse (bank bridge can be recourse) | Usually non-recourse |
| Prepayment | Open after a short lockout / spread maintenance | Yield maintenance, defeasance, or step-down |
| Closing speed | 30 to 45 days | 45 to 75 days |
| Right for | Value-add, lease-up, time pressure | Stabilized, long hold |
Use bridge when
- You are repositioning the property and rents are 12 to 24 months from market.
- The property is leasing up out of construction and isn't yet at the 90% occupancy permanent lenders want.
- You need to close an acquisition in 30 days and don't have time for an agency or life company process.
- An existing loan is maturing inside six to twelve months and the property needs more time to qualify for clean permanent debt.
Use permanent when
- The property is producing predictable NOI and is at stabilized occupancy.
- You plan to hold for at least five years.
- Rate certainty matters more than optionality.
- You want to lock in agency or life company pricing while it's available.
The bridge-to-permanent financing process
Most value-add deals follow a two-step capital structure: bridge to fund the renovation and lease-up, then refinance into permanent debt at stabilization. The structural risk is the take-out: you have to be confident the property will qualify for permanent debt at the rate environment expected at exit. Stress-test that exit before signing the bridge term sheet.
The math that decides it
The real test is the carry cost over your actual hold. If you plan to hold five years, model the bridge plus the perm refi versus a single perm at origination. Include the bridge spread premium, the rate cap cost, the lender fees on both loans, and the legal and third-party reports twice. The answer is usually clear. If it isn't, you may not need the bridge.
