Prepared for lenders, CDCs, and federal agencies to SBA SOP 50 10 8, USDA 7 CFR Part 5001, and conventional underwriting standards. Fiduciary duty runs to the lender and the agency, never the borrower. 4,000+ engagements since 1998 covering $41.2 billion in evaluated project value. So far in 2026: 41 engagements and $1.54 billion evaluated — 17 SBA, 11 USDA.
Mixed-use feasibility is the sum of its component analyses plus an honest treatment of their interaction. Each use — retail, residential, office, hospitality — must clear its own demand test independently, because cross-subsidy assumptions are where mixed-use pro formas fail. The study then evaluates the genuine synergies: daytime population supporting ground-floor retail, residential rent premiums attributable to amenity adjacency, shared parking economics under time-of-day demand curves. Phasing risk receives explicit treatment, since the financing of later phases typically depends on the performance of the first.
The methodology runs component-level demand analysis to the same standard as our single-use studies, with a consolidated financial model that presents each component as a standalone pro forma alongside the combined statement — the same component-financing architecture the firm has applied to tribal travel-center and strip-retail combinations. Sensitivity analysis runs at both the component and consolidated level.
Every Wert-Berater financial model is fully linked with no hardcoded values, so any reviewer can stress any input. Deliverables comprise a complete narrative report and the linked Excel model, with ten-year pro forma, sensitivity analysis at ±5, 10, and 15 percent, interest-rate stress from +0.5 to +3.0 percent, and ratio analysis benchmarked against RMA and IBISWorld data.
SBA engagements are prepared to SOP 50 10 8, including its debt-service-coverage minimums of 1.15x operating and 1.00x global. USDA engagements follow RD Staff Instruction 5001 across the Business & Industry, Community Facilities, REAP, and Value-Added Producer Grant programs. Conventional engagements are built to the lender's stated coverage standard, typically 1.20x. Mixed-use projects are financed through conventional construction lending most commonly, with SBA 504 applicable to owner-occupied components and USDA programs where rural town-center economics apply; the study allocates uses, costs, and collateral in the manner the program's eligibility rules require.
The firm's component-financing methodology — standalone pro formas per use with combined synergy analysis — was developed across gas-station-plus-retail-strip and town-center engagements, including a $3,969,648 tribal travel center with retail strip in Nevada. Independence is non-negotiable: determinations follow the evidence and are not revised under pressure, and studies are built to pass lender, agency, and third-party review without exception items.
A mixed-use development feasibility study is not a single pro forma with uses stacked on top of one another. It is a set of parallel analyses — one per use — that are then consolidated into a combined model showing where the components reinforce each other and where they create compounding risk. For a project combining ground-floor retail with upper-floor residential and a structured parking deck, that means three independent demand tests, three standalone income statements, and one consolidated statement that makes the interaction explicit.
Every deliverable is prepared in the same engagement: bound narrative report, fully linked Excel model, and access to the live model through the secure client portal.
Demand analysis for a mixed-use project requires a separate counting methodology for each component, because the trade area, the competitive supply, and the absorption timeline differ by use. Retail demand is measured against consumer expenditure patterns, daytime population, and the existing supply of leasable square footage within a drive-time radius. Residential demand is measured against household formation, vacancy trends in comparable product, and the depth of the income cohort that can support the proposed rent schedule. Office or hospitality components require their own occupancy and rate analysis drawn from sources appropriate to that use.
Primary data sources vary by component but typically include municipal building-permit records and certificate-of-occupancy filings to track competitive supply entering the market; county assessor and GIS data for parcel-level land-use mapping; traffic-count data from state departments of transportation for retail site evaluation; utility interconnection and capacity records where infrastructure constraints affect development timing; and trade-association absorption benchmarks for the residential and retail components. Licensing registries — liquor, food-service, and business licenses — provide a ground-level census of operating retail tenants that supplements assessor data and catches unlicensed vacancies that aggregate databases miss.
The competitive-supply analysis distinguishes between existing supply, projects under construction with issued permits, and announced projects without entitlements — because only the first two categories represent near-term competitive pressure on lease-up. Announced projects without permits are noted but not weighted equally in the absorption model.
Most mixed-use pro formas fail at the lender's desk because one or two optimistic assumptions carry the coverage ratio across the minimum threshold. The study identifies those load-bearing assumptions at the outset and subjects each to explicit stress testing, so the lender can see exactly how much margin separates the base case from a coverage breach.
SBA lenders reviewing a mixed-use project under SOP 50 10 8 must confirm that the 1.15x operating coverage and 1.00x global coverage minimums are met at the project level. Where an SBA 504 debenture finances only the owner-occupied component — common when a developer occupies ground-floor commercial space — the lender must be able to isolate that component's cash flow and collateral from the residential or rental portions. The feasibility study allocates revenues, expenses, and collateral by component in the format the program's eligibility rules require, so the credit file is complete without additional analyst work.
USDA Business & Industry and Community Facilities lenders apply RD Staff Instruction 5001 and look specifically at whether the project serves a rural community's demonstrated need, whether the market study documents that need with primary data rather than projections alone, and whether the phasing plan is realistic given local contractor capacity and permitting timelines. Town-center mixed-use projects in rural markets frequently involve historic tax credits or New Markets Tax Credits layered into the capital stack; the study documents the project economics before and after those credits so the lender can underwrite the base case independently.
Conventional construction lenders typically require 1.20x stabilized coverage and want to see a stress case in which the retail component leases at 80 percent of projected rent — because retail is the component most likely to underperform in the first operating year. The interest-rate stress from +0.5 to +3.0 percent is directly responsive to that concern.
The fixed fee for a mixed-use development feasibility study is quoted within one business day of a project description. Because mixed-use engagements require parallel component analyses and a consolidated model, the scope is larger than a single-use study, and the fee reflects that scope. There are no contingent fees: the fee does not change based on the finding, and no additional charge is assessed if the determination is unfavorable to the sponsor. Wert-Berater's fiduciary duty runs to the lender and the reviewing agency.
Standard delivery is 10 to 15 business days from receipt of a complete data room. A complete data room for a mixed-use project includes site control documentation, the proposed program of uses with square footages and unit counts, the preliminary cost estimate or contractor budget, the proposed capital stack and financing terms, any executed or letters of intent from anchor tenants, and the sponsor's operating assumptions. Rush delivery is available when the lender's commitment timeline requires it.
Once the engagement is complete, the fully linked Excel model is published to a secure client portal. The model recalculates when any input changes, so a lender's credit officer can run a stress scenario — lower retail rents, higher construction costs, a wider interest-rate spread — without requesting a revised report. The narrative report documents the methodology, the data sources, the competitive-supply findings, and the explicit statement of conditions. No value is hardcoded in the model; every cell that drives an output traces back to a labeled assumption.
The residential element of a mixed-use scheme is underwritten as its own asset, not as a share of the overall project, because its demand pool, pricing evidence and cost structure are independent of the commercial space beside it. For-sale lots or homes within the scheme are tested as a residential subdivision feasibility study. A horizontal rental-home component is tested as a Build-to-Rent community feasibility study. Conventional stacked apartments are tested as apartment and multifamily feasibility studies, and a land-lease community as a manufactured housing community feasibility study. Each is then reconciled into the scheme-level cash flow rather than assumed to perform at the blended average.
The fee is fixed and quoted within one business day of receiving a project description. Because a mixed-use study requires independent demand analysis and a standalone pro forma for each component — retail, residential, office, or hospitality — plus a consolidated model, the scope is larger than a single-use engagement and the fee reflects that. No fee is contingent on the outcome.
Standard delivery is 10 to 15 business days from receipt of a complete data room. The data room must include the proposed program of uses, preliminary cost estimates, the proposed capital stack, site control documentation, and any executed tenant letters of intent. Rush delivery is available. The clock starts when the data room is complete, not when the engagement is signed.
Each component must clear its own demand test independently, and the interaction between components creates compounding risk that does not appear in single-use analysis. Shared-cost allocation between retail and residential, phasing dependency between financing stages, and retail lease-up pace that lags residential absorption are the three failure points most commonly missed in sponsor-prepared pro formas.
Yes. The study allocates revenues, expenses, and collateral by component in the format SBA SOP 50 10 8 requires, presenting each component as a standalone pro forma alongside the consolidated statement. The SBA-eligible owner-occupied component is underwritten to the 1.15x operating and 1.00x global coverage minimums; the residential component is presented separately so the lender's credit file is complete without additional analyst work.
No feasibility study guarantees loan approval. The study documents the market evidence, tests the financial assumptions, and presents a determination based on the evidence. The determination follows the data. Approval decisions rest with the lender and, where applicable, the reviewing agency. The study is built to pass lender, agency, and third-party review, but it does not predetermine any credit decision.
Retail demand analysis draws on consumer expenditure data, daytime population estimates, traffic counts from state transportation departments, municipal building-permit and certificate-of-occupancy records for competitive-supply tracking, county assessor and GIS parcel data, and business and food-service licensing registries. Licensing registries provide a ground-level census of operating tenants that catches vacancies aggregate commercial databases routinely miss.
