What is LIHTC and how does it work?

LIHTC (Low-Income Housing Tax Credit) is a federal tax credit under IRS Section 42 that subsidizes affordable rental housing. There are two streams: 9% credits for new construction (~70% of project cost subsidy, competitive QAP allocation) and 4% credits paired with tax-exempt bonds (~30% subsidy, non-competitive). Investors (typically banks under CRA obligations) purchase tax credits — receiving 10 years of credits — providing project equity. In exchange, the property must rent to households ≤60% AMI for 15-year compliance period + 15-year extended use (30 years total).

Who owns affordable housing — is there a public REIT?

There is no pure-play public LIHTC REIT. The affordable housing market is dominated by private syndicators (Boston Capital, Hudson Pacific Tax Equity, Hunt Capital Partners, R4 Capital, Enterprise Community Investment) who pool LIHTC investor capital, and non-profit + for-profit developers (NRP Group, McCormack Baron Salazar, Pennrose, Related Affordable, Eden Housing). Sun Communities (SUI) and Equity LifeStyle Properties (ELS) hold manufactured-housing communities serving lower-income households without LIHTC structure.

What is AMI and why does it matter for affordable housing?

AMI (Area Median Income) is the median household income for a metropolitan or rural area, published annually by HUD. Affordable housing rent restrictions reference AMI — a unit at "60% AMI" can rent to households earning ≤60% of the area median, with rent capped at 30% of 60% AMI ÷ 12 (e.g., MSA AMI $80K → 60% AMI = $48K → max rent = $1,200/month for studio/1BR). 30% AMI is "extremely low income"; 50% is "very low income"; 80% is "low income"; 80-120% is "workforce." LIHTC requires 40% of units at ≤60% AMI OR 20% at ≤50% AMI.

Affordable Housing KPIs.

Affordable Housing is rent-restricted multifamily serving households at 30-80% AMI (Area Median Income). The dominant financing structure is Low-Income Housing Tax Credit (LIHTC) Section 42 — federal tax credits sold to investors (banks, insurance companies) creating equity for development; LIHTC funds 70%+ of new affordable construction. Other structures: HUD Section 8 project-based contracts (PBRA), Section 202 (senior), USDA Section 515 (rural), state/local inclusionary zoning. Performance is measured in occupancy (typically 96-99% — waitlist-driven), compliance certification rate (annual income re-certification), Davis-Bacon prevailing wage compliance during construction, and 15-year LIHTC compliance period + 15-year extended-use commitment. Asset value structure differs fundamentally from market-rate multifamily — restricted rents cap NOI; the value is in long-term cash flow + tax credits + qualified opportunity zone overlays. There is no pure-play public LIHTC REIT — the market is dominated by syndicators (Boston Capital, Hudson Pacific, Hunt Capital Partners, Enterprise Community Investment, R4 Capital) and developers (NRP Group, McCormack Baron Salazar, Pennrose). Ilora.ai ingests LIHTC compliance reports, HAP contracts (HUD Section 8), tenant income certifications, IRS Form 8609 + 8823, and Davis-Bacon payroll, then surfaces compliance-period risk + qualified contract eligibility.

NOI: Total revenue minus operating expenses (excludes financing and capital costs). The primary measure of property-level profitability.
Cap Rate: Net Operating Income divided by current property value. Expresses unleveraged annual yield as a percentage.
DSCR: Net Operating Income divided by total annual debt service. Lender-required cushion measure; below 1.0 means NOI cannot cover debt.
LTV: Loan amount divided by property value. Lower LTV = lower lender risk.
OER: Operating expenses divided by gross revenue. Lower is better, but varies by property type (hotels run higher than triple-net retail).
GRM: Property value divided by gross annual rental income. Quick valuation shortcut; less precise than cap rate.
IRR: Annualized return on investment accounting for time value of money across the full hold period.
CoC: Pre-tax annual cash flow divided by total cash invested. Measures the cash yield, not total return.
DCF: Valuation method that projects future cash flows and discounts them to present value at a chosen rate.
TTM: A rolling sum of the most recent 12 months. Smooths seasonality for KPI comparisons.
EGI: Gross potential rent minus vacancy and credit losses, plus other income (parking, laundry, fees).
LTL: Difference between market rent and current contract rent across the rent roll. Measures lease-up opportunity on turnover.
Renewal: Percentage of expiring leases that renew. Higher renewal rates indicate retention; turnover costs avoided.
Concessions: Concessions (free months, discounts) divided by gross rent. Measures pricing pressure.
RUBS: Method of allocating master-metered utility costs to residents based on unit area or occupant count.
