The question I field most from affordable housing developers isn't whether to pursue Low-Income Housing Tax Credits. It's which credit makes sense for their specific deal. The answer isn't as obvious as you'd think.
Yes, the 9% competitive credit delivers roughly 70% of development cost as equity versus 30% for the 4% non-competitive credit. But that math assumes you can actually win a 9% allocation, that your deal size supports the structure you're pursuing, and that you've accurately modeled the true cost of capital across both scenarios.
After placing financing on hundreds of LIHTC deals across California and nationally, I can tell you the "more equity is always better" assumption has cost developers years of wasted applications and millions in pursuit of the wrong credit type.
The 2021 Game Changer
The federal 4% credit became significantly more attractive when Congress established the 4% floor in 2021 under IRC Section 42(b)(2). Previously, the 4% credit floated with federal rates, sometimes dipping to 3% or lower. The fixed 4% floor provides pricing certainty that makes bond-financed deals much more predictable to underwrite.
Current investor pricing generally ranges from $0.85 to $0.95 per credit dollar, depending on the investor, deal quality, and market timing. That translates to roughly $9 million in credit equity on a $30 million development cost deal using the 4% credit, compared to approximately $21 million using the 9% credit.
But here's what that spread doesn't tell you: the 4% deal can close on your timeline once you secure bond allocation. The 9% deal closes when TCAC says it closes, assuming you win the allocation at all.
When 9% Makes Sense
The competitive credit remains the right choice for deals between $8 million and $20 million in total development cost. Below $15 million, the overhead costs of bond issuance typically make 4% deals uneconomical. You're paying bond counsel, a trustee, rating agencies, and underwriters to structure financing for a deal that doesn't have enough scale to absorb those costs efficiently.
The 9% credit also makes sense when you have a strong scoring profile. Family housing in high-need areas with experienced sponsors and existing investor commitments consistently score well in TCAC rounds. If you're developing on a transit-oriented site with local government support and a general contractor already under contract, pursue the 9% credit.
But understand the competition. California's TCAC scoring is brutal, and many qualified applications don't reach the winning threshold. I've seen developers spend three years cycling through TCAC rounds, burning through predevelopment budgets while their land costs and construction estimates inflate.
The 9% credit works when you can afford to wait and when your deal genuinely competes at the top of the scoring range. It doesn't work as a default strategy.
When 4% Makes Sense
Bond-financed deals with 4% credits typically make economic sense starting at $20 million in total development cost. The structure becomes increasingly attractive as deal size grows because bond issuance costs get spread across more units.
The 4% credit also works for deals that pencil with additional gap financing but struggle to score competitively for 9% allocations. Maybe you're developing senior housing in a moderate-income area, or you're a newer sponsor without the track record that TCAC rewards. The 4% credit provides an achievable path to closing.
Consider a typical $30 million, 80-unit family development in Los Angeles County. The 9% scenario might structure as $21 million in credit equity, a $6 million construction and permanent loan, and $3 million in local gap financing. Clean, simple, and heavily equity-weighted.
The same deal using 4% credits might structure as $9 million in credit equity, $15 million in tax-exempt bond financing for construction and permanent loans, and $6 million layered from state programs like AHSC or NPLH plus local housing trust funds. More complex, but achievable without winning a competitive allocation.
Execution Differences
Timing represents the biggest operational difference between credit types. TCAC operates on a round schedule with multiple application deadlines per year. Win an allocation, and you're typically looking at 12 to 18 months from award to closing as you finalize construction documents, permits, and financing.
Bond-financed deals operate on your timeline once you secure bond allocation from the state or a local issuer. You can move directly to construction loan closing as soon as your financing is committed and your permits are ready.
Gap financing requirements also differ substantially. Nearly every 4% deal needs significant state and local soft debt to make the economics work. That means multiple funding applications, compliance with varying program requirements, and coordination across numerous financing sources.
Some 9% deals close without any gap financing beyond the credit equity and a modest construction loan. Others need gap financing, but typically less than comparable 4% deals.
Lenders evaluate the credit types differently as well. Mission-focused CDFIs are comfortable with both structures and often prefer the deeper affordability that gap-financed 4% deals can achieve. Life companies with affordable housing platforms are increasingly active on 4% permanent take-outs, particularly for larger deals with strong sponsors.
Agency lenders, including Fannie Mae's MAH program and Freddie Mac's TAH program, actively finance both credit types as permanent lenders, with some construction-to-permanent products available. Mainstream commercial banks often struggle with 4% complexity, particularly the coordination required across multiple funding sources.
Common Mistakes
The most expensive mistake I see developers make is pursuing 9% credits when their deal isn't genuinely competitive. TCAC applications cost money, time, and opportunity cost. If you're not scoring in the range that wins allocations, three years of applications will cost more than the additional gap financing required for a 4% deal.
Conversely, pursuing 4% credits at insufficient scale wastes everyone's time. Bond issuance for a $12 million deal rarely makes economic sense. The overhead costs overwhelm any benefit from avoiding competitive allocation.
The subtler mistake is failing to secure gap financing commitments before submitting LIHTC applications. Both credit types benefit from committed financing sources, but 4% deals absolutely require it. Don't submit a TCAC application for a 4% deal without term sheets from your gap financing sources.
Underwriting Reality
Lenders scrutinize 4% deals more heavily on operational cash flow because the capital stack is thinner on credit equity. Your 15-year operating pro forma matters more when you're carrying $15 million in bond debt versus $6 million in conventional debt.
That means conservative rent growth assumptions, realistic expense projections, and adequate replacement reserves. Lenders want to see coverage ratios that work through economic cycles, not just at stabilization.
Credit investors evaluate both deal types similarly on development risk and sponsor quality. But they price 4% deals slightly higher on operational risk given the debt service requirements.
The Bottom Line
Neither credit type is inherently superior. The right choice depends on your deal size, site economics, competitive position, timeline requirements, and gap financing capacity. Developers who automatically pursue 9% credits because "more equity is better" often waste years in competitive rounds they're not positioned to win.
Developers who pursue 4% credits without sufficient scale or gap financing capacity waste months on applications that never pencil.
The successful developers I work with model both scenarios early in predevelopment. They honestly assess their competitive position for 9% credits, their capacity to secure and manage gap financing for 4% deals, and their timeline requirements. Then they commit to one strategy and execute it efficiently.
Before you commit a dollar to bond counsel or file your first TCAC application, have a broker model both scenarios. We do this for clients every week and often recommend the opposite of what they walked in expecting. The math doesn't lie, but it only works when you're running the right calculation.
