Old Knob and Tube Wiring or Failing Furnace: Selling a Cleveland House That Won't Pass Inspection

October 13, 2026 · Greater Cleveland home buyers

Fixing up a Cleveland house to pass a traditional inspection runs anywhere from $8,000 to $35,000, depending on what's wrong and how deep the problems go. Some houses need a lot more. The range is wide because Cleveland's housing stock is old, and old houses hide things behind the walls.

If you're sitting on a house with knob and tube wiring, a furnace that's on its last leg, or a laundry list of issues from a buyer's inspection report, you're not alone. This is normal in Cuyahoga County. Whole neighborhoods in Cleveland, Lakewood, Parma, and Euclid were built in the 1900s through the 1950s, long before modern code existed. The house isn't broken. It's just old, and buyers using FHA or VA loans often can't get approved until major items get fixed.

What drives the price

A realistic example

Here's a typical situation we see across inner-ring suburbs like Cleveland Heights, Maple Heights, and Garfield Heights. A 1925 colonial, 1,400 square feet, still has some original knob and tube wiring in the attic and second floor. The furnace is 22 years old. The inspector also flags a few plumbing issues and some peeling exterior paint, likely lead-based given the age.

A buyer's lender won't close until the wiring is addressed and the furnace is replaced. That's roughly $10,000 for a partial rewire, $5,500 for a new furnace, and another $2,000 for plumbing patches. Add in paint stabilization for $1,500. The seller is now looking at $19,000 before the house can even go back on the market, with no guarantee the next inspection won't turn up something else.

That's the math that makes a lot of Cleveland homeowners stop and ask if there's a different way to sell.

Where people overpay

The biggest overpay happens when sellers hire an electrician or contractor to do a "quick fix" just to get past one inspection, then the next buyer's inspector catches something else and it starts all over again. Patching knob and tube instead of addressing the whole circuit often means paying twice.

Another common mistake is assuming a full rewire or repipe is required when a licensed electrician could actually certify part of the existing system as safe. Not every knob and tube wire needs to come out immediately, depending on how it's used. Getting one inspector's opinion and treating it as the final word can cost thousands more than necessary. A second opinion from a licensed trade pro, not just the home inspector, is worth the time.

People also overpay by guessing instead of getting real bids. A homeowner hears "$20,000 rewire" from a neighbor's experience and assumes that's their number too, when their house might be smaller, easier to access, or already partially updated. Every house is different. Guessing leads to either overspending out of fear or underbudgeting and getting stuck mid-sale.

How to get an accurate quote

• Get a licensed electrician to walk the house, not just rely on the inspection report
• Ask for a written bid broken down by task, not a lump sum
• Get two or three quotes on the biggest items: wiring, furnace, plumbing
• Ask your contractor what's actually required for code versus what's optional

Or skip the bidding process altogether. If the idea of coordinating electricians, furnace installers, and plumbers while still living in the house sounds exhausting, you don't have to do it. A lot of Cleveland sellers just want out from under the repair list.
