HUD Multifamily Market Study and Feasibility Study for 221(d)(4), 223(f) and 220 Loans

Section 221(d)(4) insures construction and substantial rehabilitation loans for market-rate, affordable and mixed-income apartments, on a term of up to 40 years after the construction period, fully amortizing and non-recourse, with the construction and permanent financing closed in a single transaction. Section 223(f) insures the acquisition or refinance of an existing community on a term of up to 35 years and does not finance construction. Section 220 insures construction and rehabilitation in designated urban renewal and revitalization areas and allows more commercial space, up to 30 percent of effective gross income against 221(d)(4)'s 25 percent of net rentable area and 15 percent of income.

The programs share an underwriting framework, the MAP Guide, HUD Handbook 4430.G, current revision March 19, 2021, and a lender channel: only a HUD-approved MAP lender may originate the loan, and the lender, not the borrower, engages and supervises every third-party analyst in the file. That rule is the reason a HUD multifamily market study is a different product from the pre-application feasibility study a sponsor commissions on its own account, and this page covers both. The asset-class methodology is on the multifamily feasibility study page; this page covers what is specific to HUD.

Mortgagee Letter 2026-01, issued January 22, 2026, fully supersedes Mortgagee Letter 2025-02 and sets the current sizing tests for 221(d)(4) new construction and substantial rehabilitation. The loan is sized at the lesser of four amounts: the requested mortgage, the statutory per-unit limit, the amount supportable by debt service, and the amount supportable by the applicable loan-to-cost ratio. For a market-rate project the ratios are 87 percent of replacement cost and 1.15x debt service coverage. For affordable projects with a rent or income restriction, and for the Middle Income Housing option the letter creates, the ratios are 90 percent and 1.11x. Both use a 7 percent vacancy factor. The letter applies immediately to any application that has not reached initial endorsement.

The Middle Income Housing option is new in 2026 and it is the single largest change in HUD multifamily sizing in a decade. A project qualifies where at least 50 percent of its units are targeted to households at or below 120 percent of area median income under a recorded use restriction, with a minimum restriction period of 10 years and in no case less than 5, and HUD requires no rent advantage analysis to qualify. The restriction has to come from a state, local or military program, which in practice means Florida's Live Local Act, Texas public facility corporations, local workforce housing ordinances and similar instruments. In many secondary markets the 120 percent limit sits above achievable market rent, so the restriction costs the sponsor little and buys 3 points of leverage and 4 basis points of coverage. MMCG's model study on a 150-unit Lakeland, Florida community prices exactly that trade.

Section 223(f) sizes at 87 percent of value and 1.15x for market-rate projects and 90 percent and 1.11x for affordable projects, on terms to 35 years. Mortgage insurance on every FHA multifamily program fell to 25 basis points, upfront and annual, under the final notice published September 23, 2025, applying to applications submitted or amended on or after October 1, 2025 that had not been initially endorsed. The reduction took 221(d)(4) from 65 basis points and 223(f) from 100 upfront and 60 annually, and it is the second reason HUD execution is competitive with agency debt at 2026 Treasury yields: at a 1.15x or 1.11x coverage test against the agencies' 1.25x, HUD proceeds are higher on the same net operating income.

The MAP Guide requires a market study for new construction and substantial rehabilitation as a complete and independent report, separate from the appraisal even when the same firm prepares both. Chapter 7 governs it. The MAP lender is responsible for selecting, approving and, where needed, training the appraisers and market analysts on its applications, and the Guide's Chapter 2 makes the lender responsible for ensuring that third-party contractors have no identity of interest with the borrower or sponsor. The market analyst may not be affiliated with any individual or institution involved in the application other than the MAP lender, and an analyst on the lender's own staff must be independent of the lending, investment and collection functions.

The qualification standard is experience, not a license. The analyst must have at least three years of experience performing market analysis for income-producing property, be currently active and regularly engaged in multifamily market studies, know real estate market conditions and financing trends in the subject's geographic area, and have experience with properties of similar complexity. There is no HUD approval of market analysts and no roster; the lender vets the analyst and HUD reviews the work. That is why a market study firm's claim to hold HUD approval is meaningless, and why MMCG's position is stated as what it is: a market analyst that MAP lenders engage.

The content is prescribed. The study must describe the geographic boundaries and characteristics of the market area, current housing market conditions, the characteristics of projects under construction and in planning, a demand estimate and analysis, and an estimated absorption period. The 2020 Guide tightened the last item: the absorption period is the time required to reach the balanced-market occupancy of 95 percent, or the market's typical stabilized occupancy, based on current net and effective demand, and a balanced market is defined as 5 percent vacancy. The study must be dated within 120 days of the pre-application and within 180 days of firm commitment issuance, and the Guide stipulates that the appraiser's vacancy and collection loss may not be less than 5 percent. HUD's own appraiser reviews and approves the market study on every new application.

A market study the sponsor commissioned before engaging its lender is not automatically wasted. The Guide's prior edition expressly accepted a market study already prepared for the borrower by a third-party analyst where it met every other requirement, and the 2020 Guide carries the same structure. Whether a given lender will adopt a sponsor's study is the lender's decision, and MMCG prepares pre-application work so that it can be adopted: to the Chapter 7 content standard, with the analyst's independence certified, and dated so that it remains inside the 120-day window when the pre-application is filed.

Section 223(f) is the exception. Acquisition and refinance applications generally do not require a separate market study; the exception is a transaction that needs a waiver of the three-year rule or a property in a volatile or declining market, where HUD may require one. A 223(f) feasibility study is therefore an underwriting of trailing operations, the capital needs assessment and the sizing tests, not a demand study, and MMCG scopes it accordingly.

Sponsors who have financed senior care under Section 232 should not assume the same market study rules apply. The Section 232 Handbook requires that for new construction a complete market study be part of the appraisal report, authored by the same appraiser and ordered by the lender, so an independent market analyst has no role. The multifamily MAP Guide does the opposite: it treats the market analyst as a separate third party, allows the market study and the appraisal to come from different firms, and requires that the two be complete and independent reports even when they come from the same one. That difference is what makes a HUD multifamily market study a product an independent consultancy can deliver, and it is why MMCG's senior care practice, described on the assisted living feasibility study page, stops at the sponsor's pre-application study while its multifamily practice does not.

On engagement by the MAP lender, MMCG prepares the Chapter 7 market study: the market area with its boundaries justified by commuting pattern and drive time; renter households by income band and their five-year projection; the competitive survey with every comparable's unit count, mix, year built, square footage and rents confirmed on the property's own website and reduced to effective rent; the pipeline from the city's permit record and planning agenda with each project's delivery quarter; the demand estimate by net and effective demand; the capture rate; and the absorption period to 95 percent, stated in months and in units per month, with the concession assumption that supports it. The analyst's certification of independence and qualifications is included, and the report is dated to the pre-application calendar.

For the sponsor, before any lender is engaged, MMCG prepares the pre-application feasibility study. It carries the same market work and adds the full operating model: the rent schedule by floor plan, vacancy at 7 percent or 5 percent as the program requires, the operating budget by line with the jurisdiction's tax rate and the current insurance cost per unit, replacement reserves, the development budget on MMCG's cost template, and the sizing of the loan under all four tests, showing which binds and by how much. It states whether the project is feasible at the proposed unit count, and, where the pipeline or the comparables' effective rents say otherwise, the count at which it is. In MMCG's model study on a 220-unit community in Celina, Texas, the binding fact is the effective two-bedroom rent at the 2022 delivery on the same road, and the determination is feasible as resized to 180 units.

A 221(d)(4) application runs from concept meeting to pre-application, HUD's pre-application review, firm commitment application, firm commitment and initial endorsement, and lenders in 2026 budget roughly 12 months from pre-application to initial endorsement, with construction starting at initial endorsement and the permanent loan converting at final endorsement after cost certification. The market study's 120-day and 180-day windows have to be managed against that calendar, and a study ordered too early is reissued. The 2026 draft mortgagee letter on MAP efficiency, posted for comment in February 2026, proposes process changes that would shorten the path; it is not in effect, and MMCG's scheduling assumes the current Guide.

HUD new construction in 2026 is being sized against a market that has turned from oversupply toward recovery. National occupancy reached 95.5 percent in August 2026, completions in buildings of five or more units were running at an annual rate of 302,000 against a 2024 peak above 580,000 for the year, and effective rents were up 0.9 percent year over year. The South, where most 221(d)(4) construction occurs, was the only region still below 95 percent occupancy and still cutting rents, and lease-up communities there were offering two to three months free. A 221(d)(4) market study in a Sun Belt submarket therefore has to carry an absorption period of 18 to 24 months, not the 12 months of 2019, and the sponsor's pre-application study has to carry the initial operating deficit that implies.

The cost of capital favors HUD. With the 10-year Treasury above 5 percent, a 1.15x coverage test at HUD's coupon produces materially more proceeds than the agencies' 1.25x, and the 25 basis point premium removed most of the historical cost of that advantage. The study states the coupon at which the 87 percent loan-to-cost test and the 1.15x test cross, because in 2026 the coverage test binds first on most market-rate projects and the loan-to-cost test only on projects with low land cost.

MMCG's HUD model studies apply the methodology end to end on real markets, with the full cost build-up, the lease-up schedule, coverage by year, sensitivity cases and the stated determination:

MMCG engagements start at $4,900 with fixed-fee scoping; the quote is issued before work begins and does not depend on the conclusion. Standard delivery is 9 to 16 business days, with rush delivery available from 5 business days. Payment terms are 50 percent at engagement and 50 percent on delivery of the final report, which satisfies the MAP Guide's independence standard because no part of the fee is contingent on the loan closing. Every study carries MMCG's written acceptance guarantee: revisions required by the lender or by HUD's reviewing appraiser are made at no additional cost. Studies are prepared under the direction of Michal Mohelsky, J.D., FMVA, Practicing Affiliate of the Appraisal Institute.
