What's in the tool

Fourteen connected tabs. One model.

From project setup through LP/GP waterfall, every piece of a 4% LIHTC feasibility analysis — connected, balanced, and recalculating live. Load the housing example to see the whole flow in one click.

Setup · Project, Rents, Budget

Rent roll with PBV, full development budget with basis tracking

Per-bedroom AMI tables, utility allowances, unit-level Section 8 PBV contracts. Line-item development budget with basis-eligibility flags feeding the 4% credit calc.

Setup · LIHTC Credits & Equity

Post-OBBBA 25% bond test and 4% credit math

Pricing, QCT/DDA boost, applicable fraction, federal grant basis reduction. Built for the post-OBBBA 25% threshold. Equity pay-in schedule by milestone.

Setup · Sources & Dev Fee

Construction + perm stacks that balance live

Two stacks, soft loans with custom waterfall treatment, sponsor-priority loans, and dev fee tranches by milestone — milestone triggers feed construction draws.

Sizing · Construction

Three-scenario construction sizing with S-curve

Two closed-form estimates plus a full cash-flow scenario simulating monthly draws against an editable S-curve. Peak balance becomes the construction loan; total interest auto-populates the budget.

Sizing · Op Pro Forma + Perm Loan

EGI-from-rent-roll and DSCR-sized perm loan

EGI auto-calculated from rent roll (with manual override). Operating expenses with required above-the-line items. Perm loan sized by target DSCR — flows back to Sources.

Analysis · 20-Year + Waterfall

20-year projections and full LP/GP waterfall

Line-by-line escalators (overridable). DSCR trajectory with 1.00 floor flags. Waterfall with DDF priority modes, sponsor-priority loans, and per-loan public lender splits.

Summary · Dashboard

Feasibility verdict, red flag panel, capital structure

Pass/warn/fail verdict with detail. Red flag panel surfacing deal-killers (gap, DSCR < 1.0, unpaid DDF). Visual capital stack, ratio benchmarks, AMI tier breakdown.

Workflow

Auto-save, JSON export, sample deal

Everything auto-saves to your browser. Export the whole deal as JSON for backup or sharing. Load the housing example in one click to see a worked deal before building your own.

⚠ What "beta" means here

This tool is honest about what it is.

It's a working screening model, not a substitute for your deal-specific underwriting. The math is built on decades of practitioner experience and current LIHTC rules — but every output should be validated against your own pro forma before you rely on it for an LOI, an investment decision, or a lender submission.

If you find a bug or have feedback, email me directly. This tool gets better when practitioners push back on it.
