I review the purchase agreements, leases and loan documents on deals like these. I am not a lender or a broker. Last updated: September 2026.

Buying the business rather than the building? See Chicago business acquisition statistics.

Your landlord raised the rent again. You have been paying somebody else's mortgage for eleven years, and you start wondering what it would take to buy the place.

There is a specific answer, and almost nobody publishes it. The SBA 504 program funds businesses buying the property they operate from, and the SBA releases every loan it guarantees. Filter that to Cook County and you get 1,505 real purchases.

First, a word that means two opposite things

On this site and elsewhere, a commercial mortgage usually means a loan on property you rent out to other people, which is a non-owner-occupied investment loan. A 504 is the reverse: it funds property your own business occupies. If you are buying a rental building, nothing on this page applies to you.

The Short Answer

The median Cook County business bought its building with a $1,030,000 stack of bank and SBA money. A bank writes the first mortgage, a Certified Development Company writes an SBA-backed second, and you put in equity. The SBA piece is only 43.1 percent of the recorded total. Two CDCs write 92.4 percent of the county. And 16.3 percent of Cook approvals are cancelled before they fund, against 10.2 percent in the collar counties.

Key Takeaways

Bank First, CDC Second, You Third

A 504 is not one loan. It is three pieces of money stacked on one building, and the buyer usually meets only the middle one before signing.

Shares computed from $3,974,370,156 of Cook County approvals. The borrower's equity is not published in the SBA file, which is why the third row is blank rather than estimated.

Most buyers arrive having talked to a bank and think the bank is the deal. On these numbers the bank is about 57 percent of it and the CDC is the rest, and the CDC is the party with the eligibility rules. Form the entity that will hold the property before the loan application, not after, and understand that the second sits behind the first if anything goes wrong, the same subordination problem that seller notes have.

What the Stack Costs

The distribution is wide. These are not uniform deals, and the middle of the range is a modest building rather than a landmark.

The stack is not the project cost

Every figure here is the bank first mortgage plus the SBA-backed second. Your own equity injection is not in the SBA file at all. So read $1,030,000 as a floor on what the median Cook County business spent on its building, never as the price. Grossing it up by an assumed down payment would be a calculation, not a measurement, and this page does not do that.

Cook County, Year by Year

Refinances are excluded throughout. The 504 program ran a commercial real estate refinance window in 2011 and 2012 that briefly doubled the apparent volume, and counting it would show a Chicago buying boom that never happened.

Two Companies Write the County

Every 504 needs a Certified Development Company. In Cook County there are effectively two.

SomerCor 504
42.2%
Wessex 504 Corp

9 CDCs appear in the Cook County data. The top two hold 92.4 percent. (SBA 504 FOIA data, computed by this firm)

This is a concentration figure and nothing more. It says which companies do the volume. It does not say any of them is better or worse, and the data cannot support that claim.

The Banks Are Not the Acquisition Banks

This is the finding that only appears when you hold both halves of the SBA file at once.

Old National Bank956.3%
Fifth Third Bank926.1%

Compare that with who finances buying a business in the same county: on the 7(a) side it is Byline Bank at 94 deals and Huntington at 90, as set out in the acquisition statistics. Huntington does not appear in the 504 top eight at all, and Chase does not lead the 7(a) table. The bank that finances buying a business is not the bank that finances buying a building, and a buyer who assumes their acquisition lender is the right call for the property is starting in the wrong place.
One row is worth a second look because it looks like an error and is not. Michigan State University Federal Credit Union, of East Lansing, is one of the busiest first-mortgage lenders on Cook County 504 deals. We checked: the loans are spread evenly across all seventeen fiscal years. A credit union four hours away is a normal participant in this market.

Which Businesses Buy Their Building

349 distinct industries appear across the funded purchases. Food dominates the count, and heavier operations dominate the size.

A restaurant buying its building is the single most common 504 deal in Cook County, and a restaurant is also the business most likely to be sold within a decade. If that is you, the building and the business are two assets on two timelines, and the valuation question gets harder, not easier, when you own the premises.

What Falls Apart

Two different failures matter here, and only one of them can be measured properly.

Cook County deals cancel more often

358 of 2,192 Cook County approvals were cancelled before funding, or 16.3 percent. Across the five collar counties it is 10.2 percent. The gap is large, it is statistically solid, and it holds whichever way the loans are counted. What the data does not show is why, so this page does not offer a reason.

Why there is no default rate broken out here. 22 Cook County loans were charged off among 638 that reached a final status. That is enough for one aggregate figure, about 3 percent, and not enough to split by industry, lender, size or year. With that few events any subdivision is noise dressed as a finding, and this firm has a standing rule against publishing one.

When You Should Not Buy

Often, leasing is the right answer

A 504 debenture runs for decades and turns the least liquid thing you could own into the anchor of your balance sheet. If you might sell or move within five years, if the space is purpose built for one use, or if the cash is worth more inside the business than in a down payment, keep leasing. Buying earns its place when the location genuinely is part of the business and you intend to be there a long time.

And whichever you choose, the occupancy cost keeps moving. Cook County property taxes and TIF extraction are the line that surprises new owners most, which is set out on the TIF article and in the cap rate guide if you plan to rent out part of the building.

What Nobody Publishes

These were each checked against the actual sources before being listed. Where something does exist but does not answer the question, that is said rather than glossed.

Two things that do exist, and are worth knowing about. The Cook County Assessor publishes a median sale comparable per square foot and a cap rate range by property type inside its township valuation reports. Those are real, government sourced and useful, but they are per township, tied to the triennial reassessment cycle, drawn for assessment purposes, and not filtered to owner-occupied property. And the St. Louis Fed maps SBA lending by metro area, though it does not separate 504 from 7(a) or carry the bank first mortgage.
Be careful what you quote. The best ranked page for SBA 504 statistics is a lender's marketing site that cites no sources, asserts a default rate the SBA does not publish, and contradicts its own other pages on both loan count and average size. Numbers on this page come from the SBA's own release, and the script that computes them ships in the open.

Methodology and Source Notes

Everything local here is computed from the SBA's own 504 FOIA release, one row per guaranteed loan, filtered to a project state of Illinois and a project county in the six-county region. Nothing is sampled or estimated. The computation is tools/sba-cook-504.py in this firm's repository, and an automated check fails if this page drifts from a fresh run of it.

Seven limits travel with every number above.

Program rules are not in the data. The 504 occupancy requirement, the equity injection tiers, the debenture terms and the job or public policy tests all come from federal regulation rather than from this file. Specific thresholds are being verified against the codified text before they appear here. [ATTORNEY REVIEW]

Update policy

The SBA refreshes the FOIA file quarterly, about a month after each quarter ends. This page is recomputed on each release and the counts move when it does.

Frequently Asked Questions

How much does it cost a Chicago business to buy its own building?

Across 1,505 funded SBA 504 purchases in Cook County between fiscal 2010 and June 2026, the median bank-plus-SBA stack was $1,030,000. A quarter were under $588,000 and a quarter above $1,979,500. That figure is a floor on the project cost, not the price. It counts the bank first mortgage and the SBA-backed second, and the borrower's own equity injection is not recorded in the data.

What is an SBA 504 loan, in plain terms?

It is three pieces of money for one building. A bank lends the first mortgage, a Certified Development Company lends a second backed by an SBA debenture, and the buyer puts in equity. Across Cook County the SBA piece was only 43.1 percent of the recorded stack. The bank carries more of the deal than most buyers expect.

Is a 504 loan the same as a commercial mortgage?

No, and the words point in opposite directions. A commercial mortgage usually means a loan on property you rent out to somebody else. A 504 funds property your own business occupies and operates from. If you are buying a rental building, 504 is the wrong program.

Who actually lends on these deals in Chicago?

Two Certified Development Companies write almost the whole county. Small Business Growth Corporation and SomerCor 504 together did 92.4 percent of funded Cook County purchases. The bank side is the opposite: 180 different banks appear on the first mortgages, and the busiest, JPMorgan Chase, holds only 11.3 percent.

Which Chicago businesses buy their own buildings?

Restaurants, by a wide margin. Full-service restaurants account for 125 of the funded Cook County purchases, limited-service restaurants 49, and bars 39. After food comes auto repair, child day care and physicians' offices. Trucking and car washes are fewer but much larger, with median stacks above $2.4 million.

How often do these deals fall apart before closing?

More often in Cook County than around it. 358 of 2,192 Cook approvals were cancelled, which is 16.3 percent, against 10.2 percent across the five collar counties. The gap is large and statistically solid, and it holds on every way of counting we tried. The data shows that it happens. It does not show why.

How many SBA 504 loans in Chicago end in default?

22 charge-offs among 638 Cook County loans that reached a final status. That is roughly 3 percent. It is one aggregate figure and it cannot responsibly be split further: with that few events, a rate for a single industry, lender or year is noise rather than a finding.

Should I buy my building or keep leasing?

Often you should keep leasing. A 504 debenture runs for decades and the building becomes the least liquid thing the business owns. If you may sell or move within five years, if the space is special purpose, or if the capital is worth more inside the business than in a down payment, leasing wins. Buying pays off when the location is genuinely part of the business and you intend to stay.
