Minimum set-asides, utility allowances, and the underwriting floors MHDC applies — Missouri

Three ways to meet the minimum set-aside

Every development receiving Federal LIHTC must make a minimum set-aside election in the initial application. Missouri offers the same three options the Code allows nationally — but unlike the 2026 QAP, the 2027 QAP no longer restates their definitions anywhere in its own text. MHDC removed the standalone "Owner Elections" section that used to carry this content; the definitions now live only in the Developer's Guide and in MHDC's own compliance manual, which state them in identical terms.

The election is formalized on IRS Form 8609, Part II, Line 8b, and is irrevocable once filed — the elected set-aside and its rent/income restrictions then run for the full Compliance Period and Extended Use Period. Miss the Minimum Set-Aside by the end of the first year of the credit period and the property doesn't qualify as low-income housing at all; the awarded credits are lost permanently, not paused for a cure. That same Line 8b election also decides whether the set-aside is tested property-wide or building-by-building: electing "yes" (multiple-building property) tests the set-aside across the whole property and allows residents to transfer between buildings without recertifying (subject to the 140% limit); electing "no" tests each building independently and treats any inter-building move as a new move-in.

Unit AMI designations and bedroom sizes are allowed to float across the development over time — but MHDC reviews the designations and bedroom mix at least annually and can enforce a remediation plan if the development has deviated from its approved plan. Skewing the unit configuration so AMI designations aren't reasonably distributed throughout the development is not allowed, either in the initial unit designations or at any point during the affordability period (2027 QAP, "Development Standards"). Bond Developments can still elect Average Income, but it doesn't replace the bond program's own minimum set-aside test — a bond deal using Average Income must independently satisfy both the LIHTC election and a 40/60 or 20/50 test for the bonds themselves; the law did not change the Minimum Set-Aside required for Bond Developments.

Outside the Average Income context, MHDC's Development Standards impose a parallel distribution rule: for mixed-income developments, affordable units must be distributed proportionately through each building, floor, and bedroom/bath type where feasible, and market-rate and affordable units must carry the same amenities and square footage (2027 QAP, "Development Standards").

Utility allowances: the QAP no longer states the list itself

The 2026 QAP's Secondary Documentation Review directly enumerated six acceptable utility-allowance sources for the application-stage schedule. The 2027 QAP's equivalent section reads differently: "Applicants must submit the secondary documentation listed in the Application Guide by the application deadline." MHDC moved the actual source list out of the QAP text into a separate Application Guide reference document that was not part of this review — so what's acceptable at application can no longer be confirmed from the QAP itself.

The FY2027 FIN-125 Application Checklist reflects the same shift: item 19c, "Utility Allowance Documentation," is required as a PDF for all applications, but the checklist names no specific approved sources — it simply requires the document.

What hasn't changed is the Developer's Guide's own Firm Submission checklist, which is narrower than either the old QAP list or the new blank check. It asks only for the current schedule from the local PHA or the HUD Utility Schedule Model (HUSM), with the applicable line items circled or highlighted, and a statement from the housing authority confirming continued validity if the schedule's effective date isn't the current year. Whether RD, HUD's own program allowance, a utility company estimate, an HFA estimate, or an Engineer Model remain acceptable at Firm Submission is addressed in neither the QAP nor the Developer's Guide — that determination now sits in the Application Guide this phase did not have access to.

Once a property is operating, the governing rules move to MHDC's LIHTC Program Compliance Manual (Revised July 2025 — confirmed as MHDC's current published edition), which sets out approved sources in federal detail. Utility costs a resident pays directly — heating, air conditioning, water heating, cooking, other electricity, water, sewer, oil, gas, and trash, but never telephone, cable, or internet — must be subtracted from the maximum gross rent to find the maximum rent a resident can actually be charged.

Sub-metered buildings get their own federal carve-out. Per IRS Notice 2009-44, utility costs a resident pays based on actual consumption in a sub-metered unit are treated as paid directly by the resident, not by the owner — but only if the rate charged matches the utility company's own rate, and any administrative fee for operating the sub-metering system is capped at $5 per unit per month unless state law says otherwise. A combined water-and-sewer bill calculated from sub-metered water consumption gets the same resident-paid treatment for the sewer portion.

The underwriting floors MHDC applies — and where its own current documents still disagree

MHDC underwrites every application against a stabilized debt service coverage standard, but the 2027 QAP and the 2027 Developer's Guide state that standard differently — and this isn't a hangover from an old document. MHDC adopted both figures, in both documents, concurrently on December 9, 2025.

Both documents agree the ceiling is 1.50 and that MHDC reserves the right to underwrite to its own standard for MHDC debt regardless of source. Where they diverge is the floor: 1.20 under the QAP versus 1.1 under the Developer's Guide (with a 1.2 floor reappearing only for Fund Balance loans specifically). Which document actually controls at underwriting is not something either document's text resolves.

The vacancy, income-trending, and expense-trending assumptions that feed directly into the operating pro forma appear only in the Developer's Guide — the QAP itself is silent on all three, exactly as it was in the prior cycle.

MHDC does not otherwise set minimum or maximum operating expense standards, citing the range of development types and regional cost variance across Missouri; each application is instead compared to existing developments of similar type, location, and design (MHDC 2027 Developer's Guide, "Operating Expenses"). Reserves are where MHDC does draw hard lines, and there are more of them than a single "replacement reserve" line item suggests.

Rents and income limits: MHDC borrows the table, its compliance manual does the rest

Missouri maintains no separate, MHDC-published LIHTC income or rent limit table. HUD publishes Area Median Income information for each Missouri county annually — MHDC posts the resulting limits on its website only as a courtesy, and verifying their accuracy remains the owner's responsibility. New limits must be implemented within 45 days of HUD's effective publication date, and HERA's Hold Harmless policy keeps a property on its prior year's limits if the new annual limits would otherwise decrease (LIHTC Program Compliance Manual (July 2025), Part 3.2(D)).

The Developer's Guide is candid about how complicated that determination is in practice, pointing applicants to a third-party tool rather than an MHDC-maintained schedule: "Income limits and maximum rent levels can be determined by accessing Novogradac & Company LLP's Rent & Income Limit Calculator... The determination of maximum income and rent limits is complex and the use of a compliance professional is highly recommended" (MHDC 2027 Developer's Guide, "Underwriting Standards — Project Income — Maximum Income / Maximum Rents").

Rent restriction runs off a Gross Rent Floor — the lowest rent limit a property will ever have to implement, which protects against HUD's published limits later dropping. For a tax credit property, the floor is either the rent limit in effect at the placed-in-service date of the first building in the property or the rent limit in effect on the allocation date, as the owner elects. For a Bond Development, the floor instead runs off the placed-in-service date or the bond reservation letter date. If a property has several placed-in-service dates, its gross rent floor can differ from a similar property down the street (LIHTC Program Compliance Manual (July 2025), Part 3.2(F)).

Where a unit carries both LIHTC and HOME assistance, the compliance manual sets a specific rule rather than a blanket override: MHDC releases separate limits for each program, and the stricter of the two controls — generally the HOME limit, since it's usually lower. Worked example from the manual: if the HOME rent for a unit is $650 and the tax credit rent is $750 before utility allowances, the owner starts from the $650 HOME rent and subtracts the utility allowance from that, not from the higher tax credit figure (LIHTC Program Compliance Manual (July 2025), Part 3.7(A)).

Workforce Housing developments carry a rent nuance of their own. A 9% development in a below-median-income county can earn a 30% eligible basis boost by setting aside 15% to 25% of total units for households between 60% and 80% AMI — but the QAP requires rents in that band to differ from the rents charged on the development's at-or-below-60%-AMI units (2027 QAP, MHDC Housing Priorities, "Workforce Housing").

What the current sources do not settle

Three things in this phase are genuinely unresolved on the record this guide could assemble from the documents MHDC currently publishes — and a Missouri pro forma should treat each as an open question rather than a settled input.

Which debt service coverage floor actually governs at underwriting — the QAP's 1.20 or the Developer's Guide's 1.1 — is not something this research could resolve. Neither document cross-references or supersedes the other's figure, both were adopted on the same December 9, 2025 date, and the gap is large enough to change how much permanent debt a deal can carry.

The Developer's Guide states that an Average Income election "may be subject to an increased per-unit compliance monitoring fee, as identified in the QAP." But the 2027 QAP's own Program Fees section states a single flat rate — $300 per low-income unit, including Workforce Housing units — with no separate or higher figure identified anywhere for an Average Income election specifically. The Developer's Guide's own Program Fees section repeats the same flat $300 figure, and its Underwriting Standards section explains that $300 as simply $10 per unit per year over the 30-year extended-use period — again with no distinct Average Income number. Whether an increased fee exists as an unpublished figure or the cross-reference is simply stale could not be confirmed from the published text.

Whether RD, HUD's own program allowance, a utility company estimate, an HFA estimate, or an Engineer Model remain acceptable utility allowance sources at application or at Firm Submission is no longer addressed in the QAP at all — MHDC moved that list into a separate Application Guide reference document this phase did not have access to. Only the Developer's Guide's narrower Firm Submission ask (local PHA schedule or HUSM) and the Compliance Manual's post-lease-up list are independently verifiable right now.
