Here's the part nobody explains before you list an older Lansing home: the wiring problem doesn't get solved once. It gets flagged once, on the inspection report, in week one. Then it gets flagged again, on an insurance underwriting file, sometimes three weeks later, by a person the seller never meets and can't negotiate with directly. The first flag is a line item. The second one can quietly reset the whole deal.

If your house sits in Moores Park, REO Town, Old Town, the Westside, Eastside, Genesee, or North Capitol, this isn't a hypothetical. Most of that housing stock predates 1950. Moores Park's signature homes are large early-1900s American Foursquares along the Grand River. The Westside carries Colonial Revival, Tudor, and Cape Cod houses from the 1920s and 1930s with original hardwood and crown molding still intact. REO Town's residential blocks were largely built before 1939. That's exactly the window when knob-and-tube wiring and, a little later, cloth-covered nonmetallic cable were standard practice. Charming trim and a wiring problem tend to arrive in the same house.

What the inspector actually writes down

A home inspector who finds knob-and-tube wiring in an accessible attic or basement will note it as a deficiency, not a deal-breaker on its own. The system isn't automatically dangerous. It's dangerous when it's been buried under later insulation, spliced with tape instead of proper connectors, or asked to carry loads it was never sized for, which after seventy or more years of appliance upgrades is close to a certainty in an unrewired house. Inspectors are trained to disclaim it and recommend evaluation by an electrician, and most buyers, at this stage, treat that recommendation as something to negotiate over: a price adjustment, a credit, or a request that the seller handle it before closing.

This is the part that feels manageable. It happens during the inspection contingency, usually within the first week or two of a signed purchase agreement, while both sides still have full room to negotiate. Sellers who get a repair credit here often think the wiring issue is resolved.

It isn't. It just moved rooms.

The second flag comes from an office you never see

Once a purchase agreement is signed and the buyer's lender is underwriting the loan, the buyer also has to bind a homeowners insurance policy before closing. That's a separate process, run by a separate company, on a separate timeline, and it does not defer to whatever was negotiated on the inspection contingency. Knob-and-tube wiring is one of the most common reasons a carrier declines a new policy outright or requires proof of a rewire before it will quote standard rates. A credit at the closing table doesn't fix that. The wiring is either replaced, or it isn't, and the underwriter only cares about the second thing.

This is where the timing gap actually bites. A Michigan closing typically runs 30 to 45 days from accepted offer. Insurance binding often doesn't happen until the final week or two, well after the inspection period has closed and the seller has usually stopped fielding backup offers.

A seller who thought the issue closed out at week two can find it reopening at week five, with far less leverage and a buyer who is now anxious about their own closing date.

Michigan's disclosure law doesn't give you a pass

None of this is optional to skip past. Michigan's Seller Disclosure Act, MCL 565.957, requires sellers of one-to-four-unit residential property to complete a written disclosure statement before the buyer signs a purchase agreement, and that statement has to cover known conditions, including unpermitted electrical work. Selling "as is" doesn't remove that obligation. It only limits the buyer's ability to demand repairs, not the seller's duty to say what's actually there. If the disclosure form goes out late, a buyer who receives it in person gets 72 hours to walk away, and that window stretches to 120 hours if it arrives by registered mail. Once those hours pass, the right to cancel on that basis expires, but the exposure to a later fraud claim over a concealed defect does not.

For a house in one of Lansing's pre-1950 neighborhoods, that means the honest answer to "has any electrical work been done, and was it permitted" matters more than in a newer subdivision. It's also the kind of question a seller can only answer accurately after having someone qualified actually look.

What replacing it actually runs

Rewiring an older Michigan home isn't a weekend project, and it isn't cheap, but the range is knowable. In nearby Ann Arbor, homes with comparable pre-1950 wiring have seen full rewires, including a new breaker panel and grounding system, run in the $8,000 to $20,000 range depending on the size of the house and how much of it requires opening walls. One documented case came in around $15,000 for a full panel and grounding upgrade, after which the owner reported an easier time getting approved and a lower premium on the new policy. The permit and the electrician's final inspection sign-off are what actually convince a new carrier to quote standard rates. Without that paperwork, you're relying on a carrier's willingness to take a chance on a specialty policy, and not all of them will.

If a buyer's carrier still says no

Not every applicant clears underwriting even after disclosure and good faith effort. Michigan maintains a backstop for exactly this situation: the Michigan Basic Property Insurance Association, the state's insurer of last resort for homeowners who can't get coverage through the standard market. It's not the cheapest option and it's not meant to be permanent, but it exists specifically for older homes with the kind of systems that make conventional carriers nervous, and knowing it's there can keep a closing from collapsing entirely while a rewire gets scheduled.

Local insurance agents who write policies in these exact neighborhoods describe the pattern the same way: Old Town's historic storefronts, REO Town's aging pipe systems in winter, Moores Park's community character. One Lansing agency's own coverage guidance for the area singles out code-upgrade coverage as "particularly critical in neighborhoods with knob-and-tube wiring and outdated electrical panels," which is a fairly direct admission that this isn't an edge case here. It's a known feature of the housing stock.

Why the timing matters more this year than it might in a slower market

Lansing has been running as a seller's market through the first half of 2026, with tight inventory, and September 2026 listing data still shows homes moving in roughly 33 days at a median list price near $150,000. That kind of market gives sellers real leverage, but only if a deal stays on track. A wiring problem that surfaces during the inspection window is a negotiation. The same problem surfacing during insurance underwriting, three or four weeks later, is a delay that risks the buyer's rate lock, their own moving timeline, and your ability to go back to any other interested party who's since moved on to a different listing.

The fix costs nothing but a phone call: get a licensed electrician to look at the wiring before you list, not after you're under contract. If knob-and-tube or cloth-covered cable is present, decide up front whether you're pricing around it, crediting for it, or replacing it, and put that decision in your listing remarks so a buyer isn't hearing about it for the first time from their own insurance agent. Keep every permit and inspection record from any electrical work already done. That paperwork is what lets a new carrier write a standard policy instead of routing your buyer to specialty coverage or the state's last-resort pool.

A few questions worth asking before you list

Does knob-and-tube wiring have to be removed before I can sell my Lansing home? No. It has to be disclosed if you know about it, and it may need to be addressed for a buyer to get standard insurance, but Michigan doesn't require its removal by law before a sale.

Does listing "as is" get me out of disclosing electrical issues? No. An as-is sale limits a buyer's ability to demand repairs. It doesn't reduce what you're required to disclose under the Seller Disclosure Act.

How would I even know if my house has the older wiring? A licensed electrician can usually confirm it in a single visit, checking exposed runs in an unfinished basement or attic first, since that's typically where it's visible before checking anywhere wiring is buried under insulation or drywall.

If you're weighing whether to rewire before listing or price around it, that's exactly the kind of decision worth walking through with someone who knows how it plays out at underwriting, not just at the inspection table.
