Worked Example: SBA 504 Gas Station Feasibility Study in Illinois
A worked example of the feasibility study a lender would read for a gas station project in Illinois, financed with an SBA 504 loan.
Illinois is the fifth-largest economy in the country and one of the six largest states for SBA lending, and a feasibility study in Illinois now sits at the center of how lenders move SBA and USDA projects from application to approval. The state operates a $1.24 trillion economy anchored by Chicago, a global financial center and the largest rail hub in North America. Its population has grown for three consecutive years after a long decline, though only because of international migration. Its commercial real estate markets range from some of the tightest industrial and apartment markets in the country to a downtown office market still near record vacancy. Loan Analytics publishes the lending, demographic and commercial real estate data behind those numbers. We prepare independent feasibility studies for SBA 7(a), SBA 504 and USDA-financed projects across Illinois when a lender requires the full report. This page lays out the current Illinois market and explains what a feasibility study consultant actually delivers for a credit file.
Illinois is one of the highest-volume SBA markets in the nation. The SBA’s own analysis ranked the state sixth by lending dollars at its fiscal 2025 pace, behind California, Texas, Florida, New York and Georgia. Illinois lenders approved about 2,835 SBA 7(a) loans worth $1.31 billion in fiscal 2025, supporting about 29,000 jobs, plus 303 504 loans worth $321 million. The average 7(a) loan of about $461,000 sat near the national figure, at a slightly lower average interest rate. Activity is concentrated in the Chicago metro, where 7(a) lending rose from about 1,750 loans in fiscal 2023 to more than 2,500 in fiscal 2025. The state’s single busiest SBA industry is long-distance trucking, a reflection of Chicago’s role in national freight. 299 Corrected lenders have made Illinois 7(a) loans over the past five years. Huntington, Northeast Bank and U.S. Bank made the most in the Chicago metro in fiscal 2025. Chicago-based Byline Bank was the tenth-largest 7(a) lender in the country by dollars and the SBA’s Illinois 7(a) Lender of the Year for the seventeenth straight year. Small Business Growth Corporation and SomerCor lead the state’s 504 lending.
The credit record shows how much property type and loan structure matter. Across ten Chicago-area asset classes, 504 loans have charged off at 4.3 percent, against 10.4 percent for 7(a) loans. Within 7(a), hotels charged off at 3.5 percent and child care centers at 3.8 percent, while restaurants reached 12.3 percent and fitness centers 13.8 percent. Nationally, SBA approvals fell in fiscal 2026 to 56,130 7(a) loans worth $32.4 billion and 6,075 504 loans worth $7.1 billion, after a 43-day shutdown froze both programs. SOP 50 10 8.1, effective 1 October 2026, now requires 1.25x debt service coverage on historical earnings for business acquisitions, an independent business valuation on every change of ownership, and a Quality of Earnings report at $3 million and above. At the same time, the combined 7(a) and 504 limit per borrower doubled to $10 million in July 2026.
The practical point for a borrower or lender searching for a feasibility study consultant in Illinois is that the document is not a box-checking exercise. Startup projects, change-of-ownership transactions where the buyer has no operating history at the site, and ground-up construction with no existing revenue to underwrite all need it. In each case, the feasibility study is the analysis that lets a credit committee size the deal with confidence. For projects in the agricultural and rural parts of the state, USDA Business and Industry loans under $5 million carry an 85 percent guarantee in fiscal 2026. The program’s rural test excludes larger cities and their urbanized areas, but many communities in outer metro counties such as Grundy, Kendall, DeKalb, McHenry and Kane still qualify. However, the administration’s fiscal 2027 budget request proposes eliminating appropriations for the program, so any capital stack that depends on B&I should carry a fallback. An Illinois feasibility study company that understands both the SBA standard operating procedures and the local submarket is doing two jobs at once: satisfying a federal documentation requirement and giving the lender a defensible basis for its credit decision.
Where Illinois Is Growing: Population and County Demographics
Illinois is the sixth-most-populous state at 12,719,141 residents as of July 2025, and it has grown for three consecutive years after roughly a decade of losses. The latest gain was modest, 16,108 residents, and its source is the single most important fact for any demand analysis. International migration added 44,752 people, while 40,017 more residents left for other states than arrived, the third-largest domestic loss in the country after California and New York. The state remains about 102,600 residents below its 2020 level. The Census Bureau expects international migration nationally to fall by roughly three-quarters from its 2024 peak, so the next estimate could show Illinois declining again. A demand case should not assume the recent growth streak continues.
The rebound is centered on Chicago and Cook County, and it is slowing. Cook County, the second-most-populous county in the nation, holds 5,194,625 residents. It gained 5,834 in the latest year, down from about 46,000 the year before, and remains 1.6 percent below its 2020 level. The City of Chicago added 5,253 residents to reach 2,731,585, after a gain of more than 22,000 a year earlier that ranked seventh nationally. The broader Chicago metro, including northwest Indiana, holds about 9.4 million people. The collar counties tell a varied story: DuPage has been essentially flat since 2020, while Kane and Lake counties hold about 526,000 and 719,000 residents respectively. Downstate, only a handful of Illinois counties have grown since 2020, and the Decatur, Peoria and Kankakee metros all lost population. Chicago-area unemployment has risen to 5.1 percent. A project that pencils cleanly in a stable collar county or a rebounding Chicago neighborhood can face very different demand in a declining downstate county, and the Illinois label alone tells a lender almost nothing. The work is in the trade area.
Illinois Commercial Real Estate: The Five Major Markets
An Illinois feasibility study lives or dies on which asset class is in question, because the five major commercial real estate sectors, concentrated in the Chicago metro, are moving in distinctly different directions.
Industrial is a genuine strength, built on Chicago’s position as the largest rail hub in North America and one of the country’s premier logistics markets. Metro vacancy runs between 4.7 and 5.9 percent in the third quarter of 2026 across five brokerages, against 6.8 percent nationally. Year-to-date absorption is between 7.5 and 12.4 million square feet. Demand is concentrating along the Interstate 80 corridor around Joliet, which accounted for about half of CBRE’s year-to-date absorption. Cushman & Wakefield reports asking rents there up 33 percent in a year, while other brokers measure gains closer to 7 percent. The pipeline of 13 to 18 million square feet is about half speculative, and it includes a 1.5-million-square-foot build-to-suit for Kimberly-Clark. Multifamily is a supply-constrained outperformer. Apartments under construction equal only about 1.7 percent of inventory, the smallest pipeline of any major U.S. market. Vacancy runs between 3.4 and 5.1 percent depending on the source, and rents reached records near $2,100 to $2,200, growing about 3 percent, the third-fastest among the top 30 markets.
The remaining sectors complete the spread. Office is the most divided. Downtown Chicago direct vacancy stands at 25.0 percent, against 13.8 percent before the pandemic. Total vacancy posted its first decline in fifteen quarters in mid-2026, but third-quarter absorption turned negative again. Trophy buildings continue to gain tenants, Fulton Market is the tightest downtown submarket at about 18 percent, and more than half of recent downtown office sales are slated for redevelopment or conversion. Suburban vacancy rose to 24.1 percent. Chicago is also a significant data center market, with 2.2 percent vacancy on about 910 megawatts of wholesale capacity and record rents. Power, however, is the binding constraint. ComEd has pushed some power deliveries to 2032 or later and requires ten-year letters of credit for projects of 50 megawatts or more. By JLL’s count, at least $200 billion in data center projects planned for Illinois went to Wisconsin, Indiana and other states instead. Retail is tight at 5.0 percent vacancy, with record asking rents and almost no new construction. Hospitality is anchored by McCormick Place and O’Hare. During major trade shows in the fall of 2026, Chicago led the 25 largest U.S. markets in revenue-per-room growth, with gains near 40 percent. Those weeks are driven by the convention calendar and should not be annualized. That divergence between sectors is precisely the question a lender asks a feasibility study to resolve.
Feasibility Studies by Asset Class in Illinois
Commercial financing in Illinois divides by property type, and each asset class a feasibility study covers turns on different questions. A hotel feasibility study in Illinois depends on demand segmentation across business, group and leisure travel in a specific submarket, set against existing and planned room supply. In downtown Chicago, it must model the McCormick Place show rotation rather than a single strong year. A gas station and convenience store feasibility study hinges on traffic counts, fuel volumes, the competitive set within the trade area, and the inside sales and food service that increasingly drive c-store margins. It also has to account for the higher loss rates this category has carried in SBA lending. A car wash feasibility study turns on rooftops, daily traffic and the membership model that now defines express-tunnel economics.
An RV park or campground feasibility study weighs Illinois’s lake, river and downstate tourism against seasonality and the conversion of transient demand into longer stays. A multifamily feasibility study tests trade-area household formation and absorption against the apartment pipeline in that specific submarket, a question of real consequence in a metro as supply-constrained as Chicago. A self-storage feasibility study measures square feet per capita against current and planned inventory in the immediate radius. An assisted living or senior housing feasibility study models the age-qualified population, penetration rates and acuity mix. A restaurant, fitness or franchise feasibility study weighs daypart demand and local competitive density against the operator’s unit economics, and it deserves the hardest stress testing, given the loss record of those categories. An industrial or warehouse feasibility study tests logistics access, clear height, power and the absorption of comparable space nearby, a matter of central importance in a state at the heart of North American rail and freight. Each of these is a distinct analysis with its own demand drivers. A state as varied as Chicago, the collar counties, Rockford, Peoria and the downstate farm belt cannot be served by a generic template that simply swaps in the word Illinois.
Construction Costs: The Illinois Picture
Hard costs feed straight into total project cost, loan sizing and the debt-service coverage a lender stress-tests, so a current read on construction inflation belongs in every Illinois feasibility study. Illinois is one of the few markets where a precise local index is available, because Chicago is one of only eight metros tracked directly by the Mortenson Construction Cost Index. Mortenson’s release for the third quarter of 2026 put Chicago costs up 2.20 percent for the quarter, faster than the national 1.58 percent, and 5.39 percent year over year. Mortenson attributes the jump to annual union contract resets and competition for electricians from data center projects. Electrical, metals and structural steel led the increases, and 2026 tariff changes had not yet been fully priced into contractor bids. A Chicago budget should carry escalation of at least 5.5 percent a year, with separate contingency for electrical and metals.
Several Illinois-specific operating costs sit alongside the construction index, and they can decide feasibility. Property taxes come first. Cook County assesses most commercial property at 25 percent of market value, against 10 percent for homes, and reassesses on a three-year cycle. The City of Chicago’s next reassessment comes in 2027, so any Chicago pro forma should model a possible step-up and the appeal path. Power costs have also risen sharply. In northern Illinois, PJM capacity prices for 2027 through 2029 have cleared between $325 and $333 per megawatt-day, against $28.92 in 2024–25. That leaves ComEd customers paying about 50 percent more for power than two years ago. State regulators project a capacity shortfall in the region beginning in 2029. Much of Chicago’s building stock is old, so renovation and adaptive reuse projects carry structural and code costs that a national average will not reflect. A market with these dynamics demands a cost basis built from current local conditions, live bids, current tax assessments and current power pricing.
What an Illinois Feasibility Study Consultant Delivers
Read the lending, demographic and market data together and the assignment becomes concrete. Illinois sends one of the largest volumes of SBA projects in the country to credit committees every year, with loss rates that vary widely by property type, and the new SBA rules now demand more evidence for each one. A population held up only by immigration, with Chicago’s rebound slowing and downstate counties declining, means a demand case has to be built at the submarket level. Five commercial real estate sectors pointing in different directions, with industrial and apartments tight and downtown office still near record vacancy, mean asset selection drives the outcome. Rising labor, power and property-tax costs mean a budget assembled a year ago is already stale.
A feasibility study consultant brings those threads together into a single third-party document written for the lender’s file. What distinguishes a credible Illinois feasibility study company is independence and evidence. The consultant is independent of both borrower and lender, and the conclusions rest on verifiable trade-area demographics, a documented competitive supply analysis, demand and absorption modeling, financial projections, and sensitivity testing organized around what a credit committee actually reviews. SBA and USDA guidelines call for exactly this kind of independent study on many startup, expansion and new-construction projects, and the lender typically orders it once the deal is in underwriting.
Several policy decisions now shape Chicago-area feasibility. A December 2025 state law created the Northern Illinois Transit Authority with about $1.5 billion a year in new funding. That averted service cuts on the CTA, Metra and Pace, at the cost of a higher regional sales tax. Chicago’s 2026 budget raised the city’s lease and cloud computing tax from 11 to 14 percent and added several consumer taxes, while rejecting a proposed per-employee head tax. On the South Side, the Illinois Quantum and Microelectronics Park is rising on the 128-acre former U.S. Steel site, backed by $500 million in state capital. Its anchor tenant, PsiQuantum, is expected to complete its facility in 2027, alongside IBM and a federal research program. The Chicago Bears’ stadium plans remain unresolved, with no deal enacted as of November 2026. A credible study treats each of these as a variable, not a background assumption.
The state’s investment profile sharpens the need for current data. Illinois’s economy produced about $1.24 trillion in 2025, fifth among the states, and grew at a 2.1 percent annual rate in the second quarter of 2026. It is one of the most diversified economies in the country. The Chicago metro anchors a global hub for futures and derivatives trading and a deep base of corporate headquarters. Beyond it, a major manufacturing base, one of the nation’s largest agricultural economies, health care, and the rail and logistics network that runs through Chicago round out the picture. Each of those forces reshapes trade-area demand, labor demand and absorption in the markets around it. None of it shows up in a generic template, which is the entire reason a project-specific study exists.
