Two triple-deckers on the same West Side block can look almost identical from the sidewalk. Same tan clapboard, same stacked porches, same worn granite steps leading up from the sidewalk. They list within a few thousand dollars of each other, and both pass their home inspections clean, no structural flags, no failed systems, nothing that stops a buyer in their tracks.
Then one closes on schedule. The other falls apart with two weeks left on the calendar, and it has nothing to do with what the inspector found. It has to do with what the insurance underwriter found after the inspector had already signed off.
If you're shopping multi-family in Manchester, especially in the affordable pockets that draw first-time investors, the inspection is not the finish line you think it is. There's a second gate behind it, slower and mostly invisible until you hit it, and it decides whether your loan actually funds.
The Gate That Doesn't Show Up on the Timeline
Most buyers plan around a familiar sequence: offer accepted, inspection period, repairs negotiated if needed, then a straight run to closing. That sequence works for a lot of Manchester properties. It breaks down for a specific slice of the multi-family stock, the two- and three-family houses built more than a century ago to house workers at the Amoskeag Mills, concentrated in the West Side, the North End, and the streets around Elm Street closest to the river.
Many of these buildings still carry knob-and-tube wiring, an ungrounded, porcelain-insulator system that was standard practice generations ago and has not been touched since. In neighborhoods like Rimmon Heights, that older wiring often means 60- or 100-amp two-wire circuits that were never sized for a modern kitchen, a mini-split, or a home office, let alone three units running all of that at once.
None of that fails a home inspection, because knob-and-tube in reasonable condition is not automatically a defect. It fails the insurance quote that comes later, sometimes after the inspection contingency has already expired, when a carrier looks at the same wiring and declines to write the policy at all. Your lender will not fund a mortgage without proof of an active homeowners or dwelling policy, so a coverage decline at this stage isn't a paperwork inconvenience. It's a closing that doesn't happen on the date in your contract.
Two Files, Same Property Type
The difference underwriters are actually looking for isn't the age of the house. It's whether the electrical work has been documented.
| Wiring status | What the underwriter sees | Typical outcome |
|---|---|---|
| Active knob-and-tube, no rewire record | Ungrounded circuits, aging insulation, no way to verify capacity | Decline, or a surcharge with a requirement to rewire before renewal |
| Rewired with permit close-out and electrician's completion letter | Modern grounded circuits, load-tested, documented in writing | Standard rates, broader choice of carrier |
That second file is what a documented rewire actually produces. A licensed electrician signs off, the city closes the permit, and you have a paper trail an underwriter can act on instead of guessing at. Manchester homeowners are currently paying somewhere around $1,249 a year on average for coverage, based on one local agency's estimate from earlier this year, and that average climbs for houses with older, undocumented systems. The gap between the two rows in that table is often the gap between qualifying for a mortgage on your contract date and not qualifying at all.
Why This Concentrates on the West Side and in Rimmon Heights
This isn't a citywide problem spread evenly across Manchester. It clusters in specific places for a specific reason. The West Side and Rimmon Heights are where the city's multi-family rental stock and its more affordable single-family homes sit side by side, which is exactly why these neighborhoods draw first-time investors and owner-occupants looking for a lower entry point. The North End carries more established single-families on tree-lined streets, generally with more renovation history behind them.
The tradeoff is straightforward. The price point that makes the West Side and Rimmon Heights attractive to a buyer running the numbers on a multi-family is tied to the same building age that makes the wiring behind the walls a live underwriting question. You don't get one without at least checking on the other.
What a Rewire Actually Buys You
A full or partial rewire is not just a safety upgrade. It is the specific documentation an underwriter is asking for, and it tends to pay for itself twice, once at your next renewal and again when you sell. Removing active knob-and-tube and replacing it with modern circuits, each one tested and labeled, gives you the permit record and the signed electrician's letter that most carriers want to see before they'll adjust a policy or write a new one.
If you're buying with plans to hold the property, that documentation is worth asking for up front, before you write the offer, not after the inspection period has already closed. If the seller had electrical work done at some point, ask for the permit and the contractor's paperwork directly. A verbal assurance that "it's been updated" is not what an underwriter will accept.
More Carriers Doesn't Mean More Yes
New Hampshire's homeowners insurance market has been genuinely expanding, with dozens of new carriers entering the state over the past year or so. That's good news in general, more competition on price, more options at renewal.
It doesn't automatically help a specific multi-family with undocumented knob-and-tube, because New Hampshire does not run a FAIR plan, the state-backed insurer of last resort that many other states use to cover properties every standard carrier has turned down. If every standard carrier here says no to a property, the fallback is the surplus lines market, which typically costs more and covers less. A wider field of carriers matters less than whether any of them will actually write your specific building, and that answer still comes down to the wiring file, not the number of companies technically licensed in the state.
Why the Clock Matters More This Year
Manchester's market has been moving fast in 2026. Through July, year-to-date closed sales were running about 9.8% ahead of the same stretch in 2025, and pending sales were up close to 19.7%, even with inventory running roughly 42.6% higher than a year earlier. Months of supply sat at 1.3, which is still a tight, competitive market by most measures.
In a market moving at that pace, a financing delay costs more than it would in a slower year. A seller with a backup offer waiting has less patience for a coverage problem that surfaces two weeks before closing, and a buyer who has to scramble for a surplus lines policy at the last minute is negotiating from a weaker position than one who checked insurability before the inspection contingency ever expired.
Before You Write the Offer, Ask
- Has the electrical system been fully rewired, or only partially updated in certain rooms or floors?
- If knob-and-tube remains anywhere in the building, is it documented as inactive, or is it still live?
- Can the seller produce a permit record or a licensed electrician's paperwork for any past electrical work?
- Has your lender confirmed insurability as an actual contingency step, not just an assumption baked into the timeline?
- Have you requested a homeowners or dwelling policy quote during your inspection period, rather than waiting until after it expires?
A Few Straight Answers
Does New Hampshire require a seller to disclose knob-and-tube wiring specifically? There's no law that requires a seller to replace it, and no standalone disclosure rule the way there is for lead paint in homes built before 1978. What matters for your closing timeline isn't the disclosure law, it's whether an insurer will bind a policy on the property as it currently sits.
Can I close without an active insurance policy in place? No mortgage lender will fund without proof of coverage. If a carrier declines based on active knob-and-tube, you'll need a bound policy from another carrier, potentially a surplus lines option, in place before your contract's closing date.
Is a full rewire worth it if I plan to hold the property long term? Generally yes. A documented rewire tends to pay back through better insurance terms at your next renewal and through a cleaner underwriting file whenever you eventually sell.
If you're weighing a multi-family purchase in the West Side, Rimmon Heights, or anywhere else in Manchester's older housing stock, the numbers on the listing sheet only tell part of the story. The wiring behind the walls tells the rest, and it's worth knowing the answer before you're two weeks from closing.
