The Opportunity

The Colerain-North Bend Gateway is a 2.55-acre, 15-parcel assemblage at the intersection of Colerain Avenue and North Bend Road in Mount Airy, Cincinnati. The site is fully controlled by the Hamilton County Land Reutilization Corporation (HCLRC) at a nominal acquisition cost of $1, and has been confirmed for development consideration by HomeBase CDC through the Mt. Airy CURE partnership.

This assessment evaluates the site across four development scenarios ranging from 57 to 165 units, each structured as a LIHTC 9% affordable housing deal. The site's combination of Qualified Census Tract status, CRA Expand tax abatement, donated land, and market rents that already align with 60% AMI limits makes this a strong LIHTC candidate—but the calculator-backed underwriting reveals that all four scenarios carry a funding gap of $4.3–5.8M that will require additional soft sources, deferred developer fee, or gap financing to close.

Site Characteristics

The site sits at a prominent commercial intersection with approximately 400 ft of Colerain Avenue frontage and 200 ft of North Bend Road frontage. The block is zoned CC-P-B (Community Commercial, Pedestrian) across 14 parcels and CC-M-B (Community Commercial, Mixed-Use) on the corner parcel—both permitting mixed-use development with an 85 ft height limit, no story cap, no FAR limit, and a density allowance of 700 sf/unit yielding up to 167 units by right.

Topography is the primary physical constraint. The buildable plateau along both street frontages sits at 925–943 ft elevation with cross-slopes of 6–16%. Behind the Colerain frontage, the grade breaks sharply—dropping 53 ft over 150 ft of plan distance at 35–40% slope. This cliff defines the eastern edge of the buildable area and creates a natural boundary for a green buffer zone.

Development Concept

The site is organized into four zones based on topography, frontage, and zoning:

• Zone 1 — L-Shape Corner (15,700 sf): Mixed-use anchor building wrapping the Colerain/North Bend intersection. Ground-floor retail at the corner (2,500 sf), residential above, tuck-under parking exploiting the cross-slope. This is the gateway identity building.
• Zone 2 — Colerain Frontage (18,160 sf): Residential building(s) stepping down the south half of Colerain. Townhomes at smaller scale, walk-up apartments at larger scale. The steepening grade (10–14%) favors individually-stepped units.
• Zone 3 — North Bend Frontage (12,642 sf): Mixed-use building east of the L, with ground-floor flex/retail (1,500 sf). Activated only in the Three Buildings and Max Density scenarios.
• Zone 4 — Hillside Buffer (30,348 sf): Non-buildable. Trail system, bioswales for stormwater management, and community garden. This zone is the amenity differentiator—east-facing units look out over the tree canopy into the valley.

Scenario Matrix

Four scenarios test the relationship between project scale, capital structure, and CDC organizational capacity:

All four scenarios use the same financing structure: LIHTC 9% tax credit equity as the primary capital source, a conventional permanent loan sized by NOI/DSCR, and CRA Expand property tax abatement (75% for 12 years). The QCT 30% basis boost generates significant credit equity ($20–43M depending on scale), but a persistent $4–6M funding gap remains across all scenarios. This gap reflects the full-cost underwriting from the deal-structuring engine—including financing carry, conservative soft cost ratios, and reserves that hand estimates typically undercount. Closing the gap will require layering soft sources: deferred developer fee, HOME loans, FHLB AHP grants, Ohio Housing Trust Fund, CDFI soft seconds, and/or Cincinnati gap grants.

The LIHTC Advantage at This Location

The most important finding of this assessment is that 60% AMI rent limits are essentially equal to market rents in Mt. Airy. The rent haircut for going LIHTC is negligible:

This means the LIHTC program is subsidizing the construction cost gap, not the rent gap. The credit generates $20–43M in tax credit equity depending on scale, while the revenue impact is minimal. This is the ideal LIHTC profile.

CDC Capacity Considerations

The site can support 165 units. LIHTC equity covers 70–85% of TDC at every scale, but a $4–6M gap remains that requires soft source layering. Beyond the capital stack, the binding constraint is organizational capacity. A $60M LIHTC deal requires:

• A dedicated development team managing $3–5M/month in construction draws
• A syndicator relationship—the tax credit investor will underwrite the CDC's capacity before committing equity
• 15+ years of LIHTC compliance infrastructure (income verification, unit mix monitoring, annual reporting)
• Asset management for 100+ units indefinitely

Comparable Scale

For context, this project at full buildout (165 units, $60.5M TDC) is comparable in scale to the College Hill Station mixed-use development on Hamilton Avenue—a multi-building, transit-oriented project that combined LIHTC, CRA, and gap financing across phased delivery. The Colerain-North Bend site has similar advantages: gateway corner, public land, and strong overlay incentives. The difference is that College Hill had an established development team from the outset; HomeBase/CURE may need to build toward that capacity through phasing or partnership.

Key Risks

• Funding gap requires soft source layering. The engine shows a $4.3–5.8M gap across all scenarios after LIHTC equity and permanent debt. This is typical for new-construction affordable deals in Cincinnati—it means the project needs 3–5 additional soft sources (HOME, FHLB AHP, Ohio HTF, CDFI, deferred fee) to close. Each source has its own application cycle and compliance requirements.
• 9% LIHTC allocation is competitive. Ohio awards credits through a scored Qualified Allocation Plan. QCT status, donated land, and CRA abatement strengthen the application, but the allocation is not guaranteed.
• Construction cost sensitivity. The $210/sf assumption is based on RS Means Q1 2026 Cincinnati metro data. The engine applies this to full gross building area including circulation, which produces higher TDCs than net-rentable-only estimates. A 14–18 month LIHTC application-to-closing timeline means construction starts in late 2027 or 2028. Even modest cost escalation widens the gap.
• DSCR at 1.16x is below target. All four scenarios produce a debt service coverage ratio of 1.16x, below the typical 1.25x lender minimum. This constrains permanent loan sizing and may require interest rate buydowns, longer amortization, or subordinate debt to reach closing.
• Hillside site work. The $450k site extraordinary budget for retaining walls, stormwater, and utility connections is a preliminary estimate. Geotechnical investigation is needed before design development to confirm foundation conditions on the 12–16% slopes.
• Competing disposition. Parcels 022800030019 (5460 Colerain, $596k sale in 2024) and 022800030064 (2559 N Bend, $3.3M adjacent sale in 2025) flag concurrent commercial assembly activity in the area. Monitor for competing interests during the predevelopment period.
