Cost factors beyond the purchase price

Property taxes and transfer costs

Illinois property taxes are higher than many states, and bills vary by municipality and assessment. Before offering, review recent tax bills and assessed values in the St. Clair County records for any property you are considering. Use the county assessor to confirm parcel details and prior-year tax history. Compare multiple addresses in both towns to see how annual costs vary.

HOA, utilities, and municipal services

  • O’Fallon subdivisions may include HOAs with dues that cover common area maintenance, green space, or pools. Always review HOA documents and budgets.
  • Freeburg has a lower prevalence of HOAs, though newer developments can still have them. Verify coverage and rules.
  • Water, sewer, and sanitation fees differ by municipality or sanitary district. Ask for typical monthly utility ranges during your inspection period.

Insurance and risk factors

  • Flood zones: Check each property on the FEMA Flood Map Service Center. If a home is in a special flood hazard area, your lender may require flood insurance.
  • Home insurance: Premiums vary by age, construction type, roof condition, and local fire protection. Get quotes for a newer O’Fallon home and an older Freeburg home to compare.

Financing and appraisal considerations

  • Appraisals rely on recent local comparable sales. Large lot or non-typical homes in Freeburg may have fewer direct comps and a smaller buyer pool.
  • VA financing is common in the area given proximity to Scott Air Force Base. Ask your lender about appraisal timelines, repair requirements, and reserves.

Decision checklist for $400K buyers

Use these questions to focus your search and avoid surprises:

  • Space vs. convenience: Do you value a bigger home and yard in Freeburg or a shorter drive and newer finishes in O’Fallon?
  • Immediate repairs: Are you ready to handle updates common in older Freeburg homes, or do you prefer turnkey in O’Fallon?
  • Monthly costs: Have you compared taxes, potential HOA dues, and insurance quotes for both towns?
  • Commute and errands: How much driving are you comfortable with for work, grocery runs, and services?
  • Long-term plans: How long do you plan to stay, and how important is future resale timing and demand in your decision?

Practical next steps

  • Pull recent sold comps: Ask your agent for 6 to 12 months of MLS sales between $350K and $450K in each town, including square footage, lot size, age, DOM, and price per square foot.
  • Confirm flood and insurance: Run the address on the FEMA Flood Map Service Center and get a homeowners insurance quote for the property type and age.
  • Verify school boundaries: Use official sources like the Illinois Report Card and cross-check with GreatSchools for objective, third-party information. Confirm school assignments directly with the district.
  • Estimate monthly costs: Review prior-year tax bills via the county assessor, request HOA dues and budgets when applicable, and ask about utility averages.
  • Plan inspections: For older homes, schedule comprehensive inspections for roof, HVAC, radon, foundation, sewer or septic, and potential lead-based paint if the home predates 1978. For newer homes, review builder warranties and energy systems.
