DuPage County is the collar-county commercial lane for Chicago metro investors who want I-88 corporate demand, suburban NNN industrial, and RLTO-free operations — without Cook County city complexity. Commercial lending in DuPage County spans warehouse and flex near Warrenville and Oak Brook, strip retail along Route 59, and stabilized multifamily in Lombard and Glendale Heights where residential DSCR math clears faster than a Chicago two-flat.
Jaken Finance Group underwrites DuPage commercial from 2300 Barrington Road, Suite 400, Hoffman Estates — Hoffman Estates HQ on the DuPage border — the same team that funds Chicago mixed-use and Illinois statewide commercial.

DuPage office-to-residential and warehouse-adjacent small MF
DuPage commercial lending skews suburban mixed-use and small warehouse-adjacent multifamily — not Loop office towers. Elmhurst and Lombard Main Street retail with upper residential units require village-specific certificate paths; Itasca and Addison I-390/I-355 logistics adjacency supports workforce rental thesis on 4–8 unit value-add.
RLTO-free advantage: DuPage residential stacks in mixed-use avoid Chicago RLTO — NOI modeling for commercial DSCR uses Illinois state law only. Operators stacking Chicago mixed-use bridge acquisition with DuPage permanent hold should entity-separate at portfolio level.
| Asset | Corridor | Bridge LTC | Exit |
|---|---|---|---|
| Main St mixed-use 2–3 unit | Elmhurst, Lombard | 70%–75% | DSCR on resi NOI |
| Small MF value-add | Addison industrial edge | 70% | Commercial DSCR |
| Office condo conversion | Oak Brook (select) | Case-by-case | Long hold |
Village permit variance: Downers Grove and Naperville turn commercial tenant improvement plans in 3–4 weeks — faster than Chicago DOB but HOA and parking minimum reviews still delay ground-floor retail openings.

Elmhurst Main Street mixed-use draw milestones
Elmhurst Main Street two-flat + retail requires village commercial TI sign-off before residential upper-unit CO — bridge draws split 40% commercial rough / 60% residential on typical $150K combined rehab. Oak Brook office condo conversions remain case-by-case — environmental and parking minimum reviews delay ground-floor retail 60+ days on select files.

Warrenville I-88 flex corridor economics
Warrenville and Oak Brook edge I-88 flex bays trade $95–$125/SF on 12,000–22,000 SF buildings — NNN tenants in pharma logistics and medical device back-office support 7.25%–8.5% cap on stabilized files. DuPage property tax on $1.2M industrial runs $28K–$34K/yr — 8%–12% below comparable Cook County warehouse after reassessment.
Worked carry: $980K value-add flex at 72% bridge LTC → $705,600 at 10.75% IO for 14 months = ~$111K interest. Re-tenant at $14/SF NNN on 16,500 SF → $231K gross; stabilized appraisal $1.24M → permanent CRE at 65% LTV → DSCR ~1.24 on $18K/mo NOI after reserves.
