How federal programs actually interact — not how the rulebook implies they do
HOME, the National Housing Trust Fund, Section 8, RAD, and USDA Rural Development don't sit quietly next to LIHTC — they change what rent you can charge, whose income limit governs, and which clock has to clear before the other one can close. Every rule below traces to a real regulation, HUD or USDA notice, or state agency document — not a paraphrase treated as fact.

HOME + LIHTC layering
HOME and the National Housing Trust Fund each require the funder to independently confirm a deal isn't over-subsidized — before committing a dollar, and it can't just adopt the state LIHTC agency's own underwriting. The two programs also run on genuinely different clocks: HOME won't finalize its commitment until it sees the actual LIHTC award, while the state agency needs a conditional HOME commitment to size the credit request. When the two programs' rent or income rules conflict, the lower one always governs — never an average, never LIHTC's number by default.

LIHTC + Section 8, RAD, and rental assistance
A voucher's contract rent is capped at the LIHTC maximum only in one specific circumstance — outside a Qualified Census Tract, with a comparable unassisted LIHTC unit to benchmark against. Inside a QCT, the normal voucher rule governs instead, and can legally exceed the LIHTC rent. A 100%-LIHTC building is exempt from annual tenant recertification — but layer in Section 8 and that exemption doesn't extend to it, so both compliance calendars have to be tracked, not just one.

USDA Rural Development + LIHTC
New Section 515 construction has been dead since 2011 — the real business today is recapitalizing existing rural properties, and USDA's own Preservation and Revitalization program just became permanent federal law (July 2026), specifically to keep Rental Assistance alive ahead of a 2028 wave of mortgage maturities. A Section 538 + 515 combo requires the complete applications filed the exact same day, or the 538 piece is automatically rejected — a real, current rule, confirmed directly against the Federal Register.

What actually wins a "narrative" scoring category
There's no public craft guide for writing a winning narrative response, because that isn't really how these categories get judged — the real rubric is a documentation checklist. California's own regulation spells out the exact tell between a genuine service-provider partnership and a vague one: a letterhead agreement, a named position, and 24 months of the organization's own experience with the specific population — not an individual staffer's résumé standing in for it.

California example: strategy beyond the point table
The point table is a gate, not the competition — real tactics for how developers actually win: sizing a bond request against the real tiebreaker formula, repositioning a unit mix toward deeper affordability after a scoring redesign, or knowing which state gap program actually pairs with which credit type before a stale assumption costs a deal an eligible source.

Corrected before publication, not after
A second, adversarial verification pass checked this content against fresh primary sources before it shipped — and found real things to fix. One citation for a USDA same-day filing rule pointed to the wrong document; two claims about a state agency's discretion and a green-building standard were narrower than an earlier draft stated. All three are corrected here, not smoothed over.
- Every claim cites its own real source — a regulation, a Federal Register notice, an agency's own document — never a paraphrase treated as fact.
- Where a claim rests on advocacy commentary rather than codified law, it's labeled that way, not stated as settled.
- A claim this platform couldn't verify is flagged as unverified, never guessed at.
