Most 2021 and 2022 bridge loan models shared a common assumption about the refinancing environment: by the time the loan matured, rates would be lower. SOFR would retreat toward its pre-2022 levels and the permanent financing market would be accessible at rates that made the economics work. That assumption was not unreasonable at the time. It turned out to be wrong in ways that have fundamentally changed the refinancing calculus for a large share of bridge borrowers.
Understanding exactly how the math shifted, and what it now takes for a bridge loan refinance to work, is among the most useful capabilities you can develop right now.
What the Original Model Assumed: $15M Loan, 5% Cap Rate, 3% Exit Rate
A typical value-add bridge loan from 2021 was built around projections that pointed toward a workable exit. Take a 100-unit multifamily property acquired for $15 million at a 5 percent cap rate on $750,000 in net operating income. The bridge loan was $11.25 million at 75 percent LTV.
The business plan called for a renovation program that would push net operating income to $900,000 within two years. At a 5 percent exit cap rate, the stabilized value would be $18 million. A permanent loan at 70 percent LTV would come in at $12.6 million, replacing the bridge and returning equity to the sponsor. At a 3 percent permanent rate, the debt service on $12.6 million is approximately $378,000 annually. Against $900,000 in net operating income, that produces a debt service coverage ratio of 2.38x. Clean execution, clean exit.
The model worked because every assumption held. None of them did.
Where the Math Breaks: 1.22x Coverage When the Lender Needs 1.25x
Run the same property through today’s numbers and the result looks different. The business plan executed. Net operating income is $900,000 as projected.
But cap rates in many multifamily markets have moved from 5 to 6 percent, per MSCI Real Assets, which puts the current appraised value at $15 million rather than $18 million. The permanent lender sizes the loan against that appraisal. At 70 percent LTV, the maximum loan is $10.5 million, which is $750,000 less than the bridge loan balance.
At a 7 percent permanent rate, consistent with Trepp data on current permanent lending activity, annual debt service on $10.5 million is approximately $735,000. Against $900,000 in net operating income, that produces a coverage ratio of 1.22x. Most permanent lenders require 1.25x at minimum. The loan does not pass.
To reach 1.25x coverage at 7 percent, the loan needs to come down to roughly $10.3 million. The gap between the bridge balance and the permanent loan has grown to nearly $1 million. The sponsor needs to fund that difference out of pocket to close the refinance, on a deal where the business plan executed exactly as planned.
The business plan worked. The financing environment did not.
The 3 Variables That Drive the Outcome
Every bridge loan refinancing in the current environment is sensitive to three variables, and all three have moved against borrowers since 2021.
The first is the permanent loan rate. Each 100 basis points of rate increase reduces the maximum supportable loan amount on a given income stream by roughly 10 to 15 percent, depending on the coverage requirement. A property that supported a $12 million permanent loan at 3 percent may only support $9 million to $10 million at 7 percent.
The second is the exit cap rate. Each 50 basis points of cap rate expansion reduces property values on the same income by roughly 8 to 10 percent. An asset worth $18 million at a 5 percent cap rate is worth $15 million at a 6 percent cap rate. The permanent loan is sized against the lower number.
The third is the spread between the bridge rate and the permanent rate. In a normal environment, refinancing into permanent financing reduces debt service. In the current environment, permanent rates are still high enough that the move from bridge to permanent does not produce the payment relief the original model assumed.
3 variables. All 3 moved in the same direction. The math broke not because of one bad assumption but because of three that failed simultaneously.
The Practical Move
Running this math is not complicated, but most sponsors are not doing it until they are close to maturity and the situation has already become urgent.
Start the conversation 12 months before maturity. Model the refinancing scenario with current cap rates (per MSCI Real Assets) and current permanent loan rates (per Trepp data). Calculate the coverage ratio at the loan amount needed to repay the bridge. If the coverage falls below the lender’s minimum, calculate the equity contribution required to close the gap.
If you can run this analysis early, present the results clearly, and frame the options around what the sponsor actually needs to do to make the refinancing work, you are providing something specific and practical.
In some cases that means helping the sponsor identify the equity required to close the gap and connecting them with capital sources willing to provide it. In others it means helping the sponsor recognize that refinancing is not viable and that a different exit path needs to be planned. Either way, the conversation goes better when it starts 12 months before maturity than when it starts 60 days out.
LoanBase helps you model bridge loan refinancing scenarios and identify the capital sources relevant to each outcome.
