Seller calculators
Estimate visible repair categories before you decide whether to fix a Chicago home or sell it as-is. Add a contingency and weigh the result against your holding cost and net proceeds. This is a planning tool, not an inspection.
A calculator is a starting point. Get a full picture with a direct review of payoff, taxes, title, condition, and timing.
Enter a rough cost for each category you can see. Use the benchmark ranges as a starting point, then add the 15 percent contingency the tool figures for surprises.

Repairs only make sense when the value they add clearly beats the cost plus the months of carrying cost while the work happens. When the planning total approaches the value lift, an as-is sale usually nets more. Run the result through the seller net proceeds and holding cost calculators before you commit to a contractor.
The planning total adds a contingency to your visible repair budget, because hidden conditions are normal once work begins.
| Category | Common range | What drives the cost |
|---|---|---|
| Roof and gutters | $8,000 to $25,000 | Size, layers to tear off, flat vs pitched |
| Water, mold, or basement | $3,000 to $20,000 | Source of water, extent, waterproofing |
| Foundation or structure | $5,000 to $40,000 | Severity, engineering, underpinning |
| Interior finishes | $10,000 to $40,000 | Square footage, paint, floors, drywall |
| Kitchen and bath | $8,000 to $50,000 | Cabinets, counters, fixtures, layout |
| Mechanical systems | $6,000 to $25,000 | Furnace, AC, plumbing, electrical panel |
Ranges are general planning figures for the Chicago area and vary by scope, access, and contractor. Always get written bids.
Start with the categories you can see, give each a rough number, and add a contingency because older Chicago homes hide surprises behind walls and below grade. This tool adds a 15 percent contingency to the visible total, which is a common planning cushion before bids come in.
The harder question is whether to spend the money at all. Repairs pay off only when they add more value than they cost, and that comparison has to include the carrying cost of every month the home sits during the work. When the planning total gets close to the value the work would add, a direct as-is sale often nets more once you account for commission, time, and risk.
A contingency of about 15 percent of the visible repair total is a common planning cushion for older homes, because problems behind walls and below grade often appear once work begins. This tool adds that contingency automatically.
Repair when the value the work adds clearly beats the cost plus the carrying cost during the work. When the planning total approaches the value lift, an as-is sale usually nets more after commission, time, and risk. Compare both with the net proceeds calculator.
No. They are general Chicago-area planning ranges and vary widely by scope, access, materials, and contractor. Always get written bids before committing to a number.
No. It is a planning estimate, not an inspection report. A licensed inspector can identify issues this tool cannot, especially structural, electrical, and hidden water problems.
It depends on whether the repairs raise your net more than they cost in money and time. If the planning total approaches the value the work would add, an as-is sale often nets more once you include holding cost and the risk of the project running over budget.
Visible, broadly appealing fixes such as roof, paint, flooring, and kitchen or bath refreshes tend to return the most. Major structural, foundation, or mechanical work rarely returns its full cost, which is why distressed sellers often choose an as-is sale.
This calculator is general information for Chicago-area owners, buyers, and investors. It is not legal, tax, lending, appraisal, or brokerage advice, and rates or rules can change. Verify figures with the appropriate professionals before money moves or documents are signed. Repair ranges are general estimates and are not a substitute for written contractor bids or a licensed inspection.
