Do modular homes hold their value? Yes — and not because a builder says so. Once a modular home is set on its permanent foundation, it's deeded real property in Massachusetts, appraised against the same site-built comps as every other house on the street, and financed with the same mortgages at the same rates. The market doesn't keep a separate ledger for houses framed indoors.
But the question deserves more than a yes, because the worry behind it is real: nobody wants to put $600,000 into a house and find out at resale that buyers see a trailer. Mike Biviano has built on the South Shore for 40+ years — stick and modular both — so here's the full answer, including where the myth comes from and what actually moves resale numbers in towns like Duxbury, Hingham, and Marshfield.

The Appraisal Test: Same House, Same Comps.
Here's the cleanest way to settle this. When a licensed appraiser values a finished modular home, they pull comparable sales — recent transactions of similar homes nearby — and adjust for square footage, condition, lot, and finishes. The comps are site-built houses, because once a modular home is married on its foundation, it is a house built to the Massachusetts State Building Code (780 CMR) like everything around it. There's no "modular column" on the appraisal form and no built-in discount.
That's not a courtesy. Appraisers work for lenders, and lenders don't do courtesies. Which brings us to the strongest piece of evidence in this whole debate.
Follow the Money: Banks Have Already Voted.
Banks are professionally paranoid. They spend their days pricing risk, and if modular homes lost value faster than stick-built, you'd see it in the loan terms — higher rates, bigger down payments, special products with asterisks. You don't. Modular homes qualify for standard construction loans and conventional mortgages on the same terms as site-built homes, full stop.
When the most risk-averse institutions in the economy treat two assets identically as collateral, that's not an opinion about value — that's the verdict. The mechanics of draws, appraisals, and lenders are covered in our Massachusetts modular financing guide.
Where the Myth Comes From: The Manufactured Mix-Up.
The depreciation story isn't invented from nothing — it's borrowed from a different product. Manufactured homes (what most people still call mobile homes) are built on a permanent steel chassis to the federal HUD code and are often titled the way vehicles are rather than deeded as real estate. An asset titled like a truck can depreciate like a truck — especially when it doesn't come with land.
A modular home shares exactly one trait with that: part of the work happens in a factory. Legally, structurally, and financially, it's a site-built house that was framed indoors. It sits on a permanent foundation, conveys by deed with the land, gets taxed by your town's assessor like every neighbor, and rides the same market. If you want the full terminology breakdown, start with our guide on what a modular home actually is.
"In forty years, no closing attorney, assessor, or appraiser has ever asked me where a house was framed. The deed doesn't have a box for it. Buyers ask about the kitchen."
Mike Biviano · 4th-Generation South Shore BuilderWhat Actually Drives Resale on the South Shore.
Once the modular question is off the table — and at appraisal, it is — your resale value comes down to the same fundamentals as every house in Plymouth County:
- Location. Town, neighborhood, school district, commute, and proximity to the water. A home in Duxbury or Hingham carries that market with it, however it was framed.
- Condition. Here modular starts ahead: lumber that never sat in the rain, framing built beyond code minimums to survive transport, and a house that was weather-tight the day it was set tends to age well.
- Layout and finishes. Buyers pay for the way a house lives — and a BMB modular home is custom-designed, so you're building the layout the market wants, not whatever the factory had on the shelf.
- The market itself. South Shore inventory stays tight. A well-built newer home competes against housing stock that's often decades older.
Notice what's not on the list: the address of the framing crew.
A Thought Experiment: Two Houses on the Same Street.
Picture two 2,400 sq ft colonials side by side in Marshfield. Same lot size, same year built, same finishes, same school district. One was framed on site over 14 months; one was framed in a factory and set by crane. Now walk a buyer through both. What's different? Nothing they can see, touch, or inspect — because structurally and legally, nothing is different. Both are 780 CMR houses on poured foundations with deeds at the registry.
The appraiser pulls the same comps for both. The home inspector runs the same checklist. The buyer's lender writes the same mortgage. The only party in the entire transaction who knows the framing history is the seller — and there's no disclosure box for "house was built indoors." If anything, the modular seller has the better story to tell: dry lumber, transport-grade framing, and a documented factory inspection record the stick-built house simply doesn't have.
And the test of time? Modular construction isn't new — factory-built 780 CMR homes have been selling and reselling across Massachusetts for decades, quietly, without anyone noticing. That's the point. If decades of resales had produced a "modular discount," every appraiser in Plymouth County would know about it. They don't, because there isn't one.
The Part Nobody Mentions: You Started $200K–$300K Ahead.
There's a value angle that gets lost in the resale debate. BMB builds at $250 per square foot while stick-built quotes locally run $400–$600 — a typical difference of $200,000–$300,000 on a comparable custom home. If two identical houses sell for the same price (and at appraisal, they do), the one that cost a quarter-million less to build didn't just hold its value. It was the better investment the day you moved in.

Protecting Value Starts Before the Build.
One honest caveat: "modular holds its value" assumes the home was built and sited well — same as it would for stick-built. A bad foundation or sloppy site work drags down any house. That's why the GC matters as much as the factory. Mike walks every lot, manages every set, and runs every build through the same 5-step process he's refined over four decades on the South Shore — and the free consultation is where you find out what your specific lot and plans pencil out to, in writing, before you commit a dollar.
