The complete timeline for buying a business in Illinois — from initial search to closing — typically takes 6 to 18 months. Some experienced buyers with clear criteria close in 90 days; first-time buyers who start without financing pre-qualification and spend months searching before identifying a target can easily take 18+ months. Understanding the phases helps set realistic expectations.
Search Phase: 1-6 Months
Finding the right business takes time. Buyers who start with clear criteria and strong broker relationships find opportunities faster. Expect to review 10–20 business listings before identifying one that warrants a letter of intent. Quality buyers who are pre-qualified and responsive to broker outreach compress this phase significantly.
Due Diligence and Financing Phase: 60-90 Days
After signing an LOI, due diligence and SBA loan processing run simultaneously. SBA loan approval from application to commitment letter typically takes 45–75 days for SBA Preferred Lenders. Due diligence review of financial, legal, and operational documents runs in parallel. Complex transactions with environmental review, healthcare licensing, or multi-entity structures add time.
Closing preparation — lease assignment, license transfers, legal documentation, and final lender conditions — adds 2–4 weeks after financing approval. Total from LOI to closing is typically 60–120 days for a straightforward SBA-financed acquisition with no unusual complications.
