Abandoned properties, estate sales, foreclosures — what full gut rehabs actually cost in Columbus, from a contractor who specializes in them.
Ranges reflect real Columbus projects. Your actual cost depends on scope, finishes, existing conditions, and timing.
| Factor | What it means | Impact |
|---|---|---|
| Foundation condition | Cracked footings, bowed walls, settling — the most expensive single issue in a zombie property. Can add $15,000–60,000. | High |
| Knob-and-tube wiring | Pre-1950s wiring must be replaced entirely. Full rewire on a 1,200 sqft house: $8,000–18,000. | High |
| Lead paint / asbestos | Testing and abatement required before demo on pre-1978 properties. Budget $2,000–12,000 depending on scope. | High |
| Plumbing condition | Cast iron and galvanized pipe replacement. Sewer line condition — always scope before buying. | High |
| Roof and envelope | Neglected roofs mean water damage cascades through the whole structure. Roof plus water damage remediation: $12,000–35,000. | Med |
| HVAC system | Systems in vacant properties fail or are stripped. Full HVAC replacement: $8,000–15,000. | Med |
| Neighborhood comps | ARV (after repair value) in the neighborhood determines how much rehab makes financial sense. | Med |
| Permit history | Unpermitted work in a zombie property creates legal liability. Verify permit history before close. | Low |
