How 4% LIHTC + Bonds Works in San Antonio: A Local Framing
The 4% Low-Income Housing Tax Credit paired with tax-exempt private activity bond financing is the dominant structure for large-scale affordable multifamily development in San Antonio. Unlike the 9% credit, which is awarded through a competitive scoring round administered by the Texas Department of Housing and Community Affairs (TDHCA), the 4% credit is non-competitive. A qualifying bond-financed deal that meets TDHCA's threshold requirements receives the credit automatically, removing the binary risk of a competitive allocation round. Since federal legislation in 2021 established a fixed 4% credit floor, the equity math improved materially, making this structure workable at deal sizes that previously required heavier subsidy layering to pencil.
In San Antonio, TDHCA governs both the LIHTC allocation and the compliance monitoring framework that will govern the property for its 55-year affordability covenant. Sponsors operating here also navigate the City of San Antonio's Neighborhood and Housing Services Department, which administers HOME and CDBG entitlement funds and aligns affordable housing investment with the SA Tomorrow Comprehensive Plan. The San Antonio Housing Authority (SAHA) is one of the most active public housing authorities in Texas and functions as a meaningful development partner on deals structured around project-based vouchers. The interaction between TDHCA's state-level requirements and San Antonio's local entitlement programs means that experienced local counsel and a housing finance team that understands both layers are not optional.
The sponsor profile that consistently closes 4% bond deals in San Antonio tends to be experienced nonprofit or for-profit developers with prior LIHTC certifications, a track record of compliance, and established relationships with both TDHCA and city agency staff. First-time sponsors attempting a deal at this scale face meaningful execution risk, particularly around bond underwriting timelines and soft debt coordination.
The Capital Stack in San Antonio
A typical 4% LIHTC bond deal in San Antonio falls in the range of $20 million to $80 million or more in total development cost. The capital stack is multi-layered by necessity. Tax credit equity from the 4% credit contributes roughly 30 percent of total development cost, and bond proceeds fund the construction loan, often through a single-close structure where the bond issuer and construction lender are the same party. This simplifies execution but concentrates counterparty risk and requires careful underwriting alignment from day one.
State soft debt through TDHCA programs, including the Multifamily Housing Programs (MHP), can provide meaningful gap coverage, though competition for those funds runs on its own timeline that does not always align with bond issuance schedules. At the local level, the San Antonio Housing Trust Fund is an active source of subordinate financing for qualifying developments and has been deployed in conjunction with city HOME entitlement dollars. The City's Neighborhood and Housing Services Department can layer CDBG and HOME funds for deals serving very low-income households, particularly in targeted neighborhoods like the Eastside Promise Zone, East Side, West Side, and South Side submarkets where the city has articulated housing investment priorities.
SAHA's project-based voucher program is a critical stack component for deals targeting the lowest income tiers. PBVs effectively underwrite a portion of the rent roll, which improves permanent loan proceeds and can make deals viable in markets where achievable rents otherwise constrain debt coverage. Sponsors should begin PBV conversations with SAHA early, as the commitment and documentation timelines are substantial. Deferred developer fee and sponsor equity round out the stack and are scrutinized closely by both lenders and TDHCA during underwriting review.
Active Lender Types for San Antonio Affordable Deals
The lender ecosystem for 4% bond deals in San Antonio reflects the broader Texas affordable housing market, with a mix of mission-driven and balance-sheet lenders at different stages of the capital structure. Mission-focused CDFIs are consistently active in San Antonio and often serve as construction or bridge lenders on deals that require flexibility around soft debt subordination and closing timeline. These lenders understand layered capital stacks and are accustomed to working alongside government soft debt sources, which makes them a natural fit for the city's deal structure.
Community banks with dedicated affordable housing platforms participate in both construction lending and bond issuance on smaller to mid-size deals. Their appetite for Community Reinvestment Act credit in markets like San Antonio keeps them competitive on pricing relative to their balance sheet size. Life insurance companies with affordable housing allocations are active on the permanent debt side, particularly for stabilized or near-stabilized properties with strong voucher backing and long affordability covenants. Their long-duration capital aligns well with the 55-year covenant structure inherent in these deals.
Fannie Mae's Multifamily Affordable Housing program and Freddie Mac's Targeted Affordable Housing program are the primary agency executions for permanent financing on stabilized 4% bond deals. Both offer favorable pricing and proceeds for properties with income and rent restrictions, and both have underwriting guidelines specifically adapted for LIHTC compliance structures. HUD's 221(d)(4) and 223(f) programs are also relevant, particularly for deals seeking non-recourse, long-term fixed-rate debt, though HUD timelines add complexity and require a sponsor prepared for a longer execution window. In San Antonio, agency lenders and CDFIs are the most consistently active across the deal cycle.
Typical Deal Profile and Timeline
A representative 4% bond deal in San Antonio involves a 150-to-300-unit workforce or affordable housing development in a targeted urban submarket, with total development costs in the $25 million to $60 million range. The income restriction profile typically targets households between 30 and 80 percent of area median income, with deeper income targeting on units supported by project-based vouchers.
From site control to construction close, sponsors should plan for a minimum of 18 to 24 months. That window includes predevelopment work, TDHCA application and underwriting, bond inducement and issuance through the relevant conduit issuer, investor equity closing, and coordination with local soft debt sources. Construction periods typically run 18 to 24 months depending on project scale and market conditions. Stabilization and final cost certification add several months beyond completion, placing the full cycle from site control to stabilization in the range of four to five years.
Lenders and investors expect sponsors to present a project with site control, a clear entitlement path, a committed soft debt strategy, experienced general contractor pricing, and a development team with at least one prior LIHTC project in the sponsor's history. Sponsors who arrive at financing conversations without a soft debt strategy already in motion are at a structural disadvantage in this market.
Common Execution Pitfalls in San Antonio
One of the most consistently underestimated risks in San Antonio is soft debt sequencing. The San Antonio Housing Trust Fund and city HOME dollars operate on their own award cycles, and those cycles do not align automatically with TDHCA or bond issuance timelines. Sponsors who assume they can layer in city funds late in the process often discover that award rounds have closed or that compliance requirements conflict with bond document covenants. Engage the Neighborhood and Housing Services Department at the earliest possible stage of predevelopment.
Prevailing wage exposure deserves careful attention in any deal that involves federal financing sources. HOME funds, HUD loan programs, and certain SAHA partnership structures can trigger Davis-Bacon wage requirements, which materially affect construction cost budgets. Sponsors who price deals based on non-prevailing-wage assumptions before confirming the full federal funding picture regularly face cost overruns that erode equity or require gap refinancing.
Site control complexity is a recurring issue in the East Side, West Side, and South Side submarkets where affordable development is most needed. Land assembly, title defects from long-term community ownership, and environmental conditions on infill sites can delay or derail projects that appeared straightforward at the letter-of-intent stage. Commission and conduct a Phase I environmental assessment and title review before committing predevelopment dollars or presenting deals to lenders.
Finally, TDHCA's application and underwriting calendar is less flexible than sponsors often assume. TDHCA imposes documentation deadlines, threshold requirements, and review cycles that do not accommodate last-minute revisions to the capital stack. Sponsors who attempt to close gaps in their financing plan after submission, rather than before, risk material delays or rejection of the application. Build the complete stack on paper before submitting, not during TDHCA review.
