LIHTC equity bridge loans: what they are and how they're sized
An equity bridge loan lends a LIHTC partnership money today against the investor's binding commitment to pay its later equity installments. It is secured mainly by an assignment of the investor's capital contribution obligation, not by the building, and it is repaid installment by installment as the investor funds. Developers use it to cut the size or cost of the construction loan, to fund costs the construction lender won't, or to bridge to the final installment after Forms 8609 are issued.
Tax credit investors don’t pay for their credits all at once. They pay in installments tied to milestones, because the credits themselves arrive only after the building is placed in service and the agency issues Form 8609. A bridge loan converts those future installments into cash now.
The pay-in schedule creates the need
A typical partnership agreement ties installments to events like these:
| Installment trigger | Why the investor waits |
|---|---|
| Closing | Partial commitment at signing |
| Construction completion | Building exists and is insured |
| Placed in service and initial lease-up | Credit period can start |
| Stabilization and permanent loan conversion | Debt risk is resolved |
| Receipt of Forms 8609 and final cost certification | Credit amount is fixed |
Investors usually pay more per credit for later pay-in, because their money is at risk for less time. The developer then faces a choice: accept a lower price for faster pay-in, or take the higher price and borrow against the later installments.
How a bridge loan is sized
The lender starts with the installments due after the loan closes and advances against them, holding back a cushion for adjusters, delays and interest:
Bridge amount = sum of future installments x advance rate - interest reserve
The advance rate is a credit decision for each lender and each investor; there is no standard figure. Lenders set it lower when the investor’s obligation has more conditions, when the installments are far in the future, or when the investor is a fund rather than a rated bank.
Worked example with assumptions only: equity of $17,054,294 (from the worked 4% deal), paid 20% at closing, 40% at completion, 25% at conversion and 15% after 8609s. The developer wants to fund more of construction with bridge proceeds.
| Amount | |
|---|---|
| Equity at closing (20%) | $3,410,859 |
| Future installments (80%) | $13,643,435 |
| Assumed advance rate (illustrative) | 90% |
| Gross bridge availability | $12,279,092 |
| Less assumed interest reserve | ($600,000) |
| Net bridge proceeds | $11,679,092 |
That $11.7 million funds costs early and shrinks the construction loan by about the same amount. The equity bridge calculator reruns this with your schedule and rate.
Is it worth it?
Compare three paths for the same deal:
- Faster pay-in, no bridge. The investor pays more at closing and completion but prices the credits lower. Cost = price reduction x total credits. On $20,800,000 of credits, one cent is $208,000.
- Slower pay-in, bridge loan. Higher price, but you pay bridge interest and fees on the advanced amount for the time it’s outstanding.
- Slower pay-in, larger construction loan. Higher price, no separate bridge, but the construction loan grows and the bank may want more guaranty support.
Interest on a bridge loan isn’t free money either. Interest that relates to the period before placed in service may be capitalized, while later interest is an operating or partnership expense. How it lands in eligible basis is a question for the cost certifier and tax counsel, not a sizing assumption.
What secures the loan
- Pledge and assignment of capital contributions. The partnership assigns to the lender its right to receive the investor’s installments, and the investor acknowledges the assignment and agrees to pay the lender directly.
- Investor estoppel and consent, confirming the amounts, the conditions and that no defaults exist.
- Pledge of the general partner’s interest, so the lender can step in.
- Guarantees from the developer covering any installment shortfall, often mirroring the developer’s guarantees to the investor.
- Sometimes a subordinate mortgage, if the lender is also the construction lender.
What the bridge lender diligences
The bridge lender reads the partnership agreement more closely than anyone except the investor’s counsel. The points that move risk:
- Conditions precedent to each installment, including deadlines. A placed-in-service deadline tied to the carryover rules is common.
- Credit adjusters. If first-year credits are lower than projected, many agreements reduce the next installment; if total credits fall, they reduce all remaining installments.
- Timing adjusters, which cut equity when credits are delivered late, often because lease-up started late.
- Repurchase or put rights, which let the investor exit if key conditions fail, returning equity and wiping out the installments the bridge relied on.
- Fund structure. When the investor is a multi-investor fund, the lender wants to know the fund’s own capital calls and who stands behind it.
Bridge cost, worked out
Continuing the example, assume the $11,679,092 bridge funds in equal monthly draws over the first 12 months, then sits fully drawn until it is repaid by the completion installment (month 20), the conversion installment (month 26) and the 8609 installment (month 32). The interest rate, an assumption only, is 7.0%.
| Period | Average balance | Months | Interest at 7.0% |
|---|---|---|---|
| Draw period | $5,839,546 | 12 | $408,768 |
| Fully drawn to completion | $11,679,092 | 8 | $545,024 |
| After the 40% installment repays $6,821,718 | $4,857,374 | 6 | $170,008 |
| After the 25% installment repays $4,263,574 | $593,800 | 6 | $20,783 |
| Total interest | about $1,144,583 |
The total runs above the $600,000 reserve assumed earlier, so the reserve would need to be roughly doubled or the bridge cut. Compare the result with the price an investor would offer for faster pay-in: if moving 40% of the equity to closing costs the deal two cents per credit on $20,800,000 of credits ($416,000), the faster pay-in is cheaper than this bridge. Faster pay-in stays cheaper until the price cut exceeds about 5.5 cents ($1,144,583 of bridge interest divided by $208,000 per cent). The point of the exercise is that the answer is arithmetic, not convention.
When a bridge makes sense
- The pay-in is back-ended, and the price difference for faster pay-in is larger than the bridge cost.
- The construction lender caps its loan below what the project needs.
- A soft lender funds late, and something needs to cover costs in the meantime.
- A historic tax credit or state credit investor pays late too, and the same structure can bridge both. See historic tax credits with LIHTC.

Questions people ask
Is an equity bridge loan the same as a construction loan?
No. A construction loan is secured by the building and repaid by the permanent loan and equity. A bridge loan is secured by the investor's promise to pay future installments and is repaid only from those installments. Many banks provide both under one facility, but they are underwritten differently.
Who is the credit risk in an equity bridge loan?
Mainly the investor. The lender looks at the investor's (or fund's) strength and at the conditions in the partnership agreement that must be met before each installment is due. If a condition fails, such as late placed-in-service or a credit shortfall, the installment can be reduced or delayed, so those conditions are what the lender diligences.
What happens if the credits come in lower than projected?
Most partnership agreements have downward adjusters that reduce the investor's remaining installments if delivered credits fall short. A reduced installment can leave the bridge loan unpaid, which is why bridge lenders size to a share of the installments and require the developer's guarantee for the shortfall.
