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 — McHenry County HQ on the DuPage border — the same team that funds Chicago mixed-use and Illinois statewide commercial.
DuPage commercial segments (2026)
| Corridor | Asset focus | Typical deal size |
|---|---|---|
| I-88 (Oak Brook, Warrenville) | Office-adjacent flex, last-mile warehouse | $800K–$4M |
| Route 59 / Naperville edge | Strip retail, medical condo | $600K–$2.5M |
| Carol Stream / Glendale Hts | Small bay industrial, value-add flex | $400K–$1.8M |
| Lombard / Downers Grove | 5–12 unit multifamily value-add | $900K–$3M |
AbbVie, McDonald’s HQ campus adjacency, and pharma/logistics back-office tenants along I-88 create durable NNN industrial demand — underwrite to actual lease and tenant credit, not pro forma market rents alone.

Worked example: Carol Stream flex value-add → NNN hold
An operator acquires a $1.05M small bay flex — 18,000 SF, one tenant at below-market rent, $12/SF vs. $16/SF market.
- Bridge at 70% LTC ($735K) — 10.25% IO, 18-month term
- Scope: $185K — dock doors, office refresh, LED, roof section — per construction cost guide
- Re-lease at $16/SF NNN — $288K gross annual rent
- Stabilized appraisal: $1.38M
- DSCR permanent at 65% LTV ($897K) — 7.875%, 25-year amortization
- NOI after taxes, insurance, maintenance reserve: DSCR ~1.22
Sponsor extracts $140K+ equity after bridge — targets second flex in Will County I-55 corridor.

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.
