Medical and dental real estate in Chicagoland splits into two very different markets. Inside the city, practices crowd into ground-floor storefronts in Lincoln Square, Pilsen, and Bronzeville, or into older medical towers near the big hospital campuses. In the collar counties, the model is the office condo park: single-story suites in Naperville, Oak Brook, Schaumburg, Hoffman Estates, Vernon Hills, and Orland Park, often near Interstate 88, I-90, or I-355.
Both markets reward owning your space if you plan to stay. Both punish practices that underestimate build-out costs. This guide covers how Chicago-area doctors, dentists, and investors finance medical office space, with real numbers. Jaken Finance Group is based in Hoffman Estates, Cook County, in the middle of the northwest suburban medical corridor. Call (833) 264-7776.
Chicago-area medical office submarkets
| Submarket | Typical product | 2026 sale price (planning) | 2026 lease rate (planning) |
|---|---|---|---|
| Naperville / Aurora (DuPage, Kane) | Condo suites 1,800–4,500 sf | $250–$375 / sf | $24–$32 / sf NNN |
| Oak Brook / Hinsdale (DuPage) | Mid-rise medical office, condo suites | $275–$425 / sf | $26–$36 / sf NNN |
| Schaumburg / Hoffman Estates (Cook) | Condo parks, freestanding clinics | $220–$340 / sf | $22–$30 / sf NNN |
| Lake County (Vernon Hills, Libertyville, Gurnee) | Condo suites near Route 21 and I-94 | $230–$350 / sf | $22–$30 / sf NNN |
| Will County (Orland Park, Joliet, New Lenox) | Freestanding clinics, strip conversions | $200–$320 / sf | $20–$28 / sf NNN |
| Chicago neighborhoods | Storefront clinics, older towers | $175–$350 / sf | $20–$34 / sf gross or NNN |
These are planning ranges from recent listings and closed deals we track, not appraisals. Suite condition changes value more than address. A second-generation dental suite with plumbing to every operatory is worth far more than a vanilla office shell.
Build-out costs are the real budget
Medical and dental space costs much more to build out than regular office. The biggest lines:
| Build-out line | Dental suite (2,400 sf, 6 operatories) | Primary care clinic (3,000 sf) |
|---|---|---|
| Plumbing, vacuum, compressed air to operatories | $55,000–$90,000 | $20,000–$40,000 |
| Electrical and dedicated circuits | $35,000–$60,000 | $30,000–$50,000 |
| X-ray shielding or imaging room | $8,000–$25,000 | $10,000–$40,000 |
| HVAC zoning | $30,000–$55,000 | $30,000–$60,000 |
| Finishes, casework, ADA restrooms | $80,000–$140,000 | $70,000–$120,000 |
| Typical total per square foot | $150–$250 | $110–$200 |
Equipment is separate and often larger. A new six-operatory dental practice can spend $250,000 to $450,000 on chairs, imaging, sterilization, and software. Equipment financing or SBA 7(a) usually covers that. The dental office renovation financing page covers remodel-only projects.
Financing options by who owns and who occupies
| Your situation | Best fit | Terms |
|---|---|---|
| Practice buying its own suite, time to close | SBA 504 | About 10% down on qualifying files; bank first plus CDC second |
| Practice buying a suite, needs to close fast | Bridge now, SBA 504 later | Bridge 8.99%–13.5% interest-only, 65%–75% of cost |
| Practice acquisition with real estate | SBA 7(a) | Up to $5 million; see SBA medical and dental practice loans |
| Investor buying a medical building to lease | Bridge, then DSCR | DSCR 5.75%–10.5% on executed leases |
| Stabilized medical NNN hold | DSCR | See DSCR loans on medical office net lease properties |
The SBA path requires the practice to occupy at least 51% of an existing building. The SBA 504 vs 7(a) comparison explains which program fits which deal.
Worked example 1 — Naperville dental condo, bridge then SBA 504
Composite file, not a live quote. A dentist has practiced in a leased Naperville suite for six years. The landlord plans to raise rent 22% at renewal. A 2,650-square-foot condo suite comes up for sale two miles away. It was a pediatric office, so the plumbing is partly in place. Another dental group is also bidding. The seller wants to close in 30 days.
| Line | Amount |
|---|---|
| Purchase price (2,650 sf at ~$302/sf) | $800,000 |
| Build-out to six operatories | $425,000 |
| Soft costs, permits, architect | $45,000 |
| Real estate project | $1,270,000 |
| Equipment (financed separately) | $310,000 |
Phase 1 — bridge to win the suite.
| Bridge line | Amount |
|---|---|
| Bridge at 70% of real estate project | $889,000 |
| Rate | 10.75% interest-only |
| Monthly interest when fully drawn | ~$7,964 |
| Dentist’s cash into real estate | $381,000 |
Construction runs five months. With draws phased in, bridge interest totals about $32,000. The dentist keeps practicing in the old suite until the new one is ready.
Phase 2 — SBA 504 takeout.
| SBA 504 structure | Amount |
|---|---|
| Bank first mortgage (50%) | $635,000 |
| CDC second (40%) | $508,000 |
| Owner equity (10%) required | $127,000 |
The 504 package can refinance the bridge because it funded the purchase and improvements of the project itself. The dentist sizes the 504 loans to retire the $889,000 bridge. Her $381,000 already exceeds the 10% injection.
Payment comparison. At an illustrative blended 504 rate near 7%, principal and interest on $889,000 over 25 years runs about $6,280 a month. Condo association dues and taxes add roughly $2,300 a month. Her renewal lease quote was $6,900 a month plus operating costs on a smaller space. Owning costs about the same and builds equity.
Worked example 2 — investor medical building in Orland Park
Composite file. An investor buys a 7,800-square-foot, single-story medical building in Orland Park. Two of four suites are leased to a physical therapy group and an orthodontist. Two suites are vacant.
| Line | Amount |
|---|---|
| Purchase | $1,650,000 |
| Tenant improvements for two vacant suites | $240,000 |
| All-in | $1,890,000 |
| Bridge at 70% of cost, 11.0% interest-only | $1,323,000 |
The investor leases the vacant suites to a family practice and a dermatology office at $25 per square foot NNN within ten months. Stabilized NOI reaches about $158,000. At a 7.5% cap rate, the building appraises near $2,107,000. A DSCR loan at 65% of value, about $1,370,000, retires the bridge. At an illustrative 7.25% rate over 30 years, debt service is about $112,000, for coverage of roughly 1.41x.
Local factors that move medical office deals
Property tax assessment levels. Cook County assesses commercial property at 25% of market value. Most other Illinois counties assess at one-third. The tax bill depends on the PIN’s rate and equalization. Pull bills from the Cook County Assessor or the relevant collar county assessor and stress them 15%. Read the Cook County property tax investor guide for more.
Condo association rules. Many suburban medical condo parks restrict use types, signage, and after-hours access. Some bar dental or imaging uses because of plumbing or radiation concerns. Read the declaration before you sign.
Certificate of Need. Standard physician and dental offices do not need one. Ambulatory surgery centers and some large imaging projects fall under the Illinois Health Facilities and Services Review Board. If your plan includes surgery, check first.
Professional licensing. Practices need active licenses through the Illinois Department of Financial and Professional Regulation. SBA lenders verify them. So do buyers of a practice.
City permits. Chicago storefront clinics go through the Chicago Department of Buildings for build-out and change of occupancy. Suburban permits run through each village, and timelines vary widely. Hoffman Estates, Schaumburg, and Naperville each have their own review cycles.
Winter construction. Interior build-out continues through winter. Parking lot, roof, and exterior work usually waits until spring.
From signed contract to first patient
Bridge interest runs every month the suite is not seeing patients. Map the steps before you pick a closing date. The timing below is a planning range for a suburban dental condo, like the Naperville example above.
| Step | Typical timing | What can slip |
|---|---|---|
| Contract, inspection, condo document review | Weeks 1–4 | Association approval of dental use |
| Bridge closing | Weeks 3–6 | Appraisal and title |
| Architect drawings and village permit | Weeks 4–12 | Village review cycles and resubmittals |
| Build-out | Months 3–7 | Plumbing, vacuum, and HVAC trades |
| X-ray registration with the state | Before first use | Missing paperwork on each machine |
| Final inspection and occupancy | Month 7 | Punch-list items |
| SBA 504 takeout | Months 8–10 | Lender and CDC schedules |
Illinois X-ray registration. Every Illinois office that runs X-ray equipment must register it with the Illinois Emergency Management Agency before the machine goes into use. Dental offices fall in Class A. There is an annual fee per machine, and the registration is updated each year. New offices file through the IEMA X-ray registration page. Moving to a new suite or adding a panoramic or cone-beam unit also means an update. Put it on the build-out schedule so imaging is cleared for use the day the operatories open.
A realistic plan is seven to ten months of carry. Size your bridge interest reserve and your personal cash for that range, not for the best case.
