Factory-built housing is gaining popularity across Canada as construction costs rise and building timelines stretch. But financing a prefab, modular, or manufactured home works differently depending on the type of home and how it is constructed. Here is what lenders, CMHC, and appraisers look for — and how to get the best financing.
Types of factory-built homes
Understanding the categories is critical because mortgage eligibility depends entirely on the classification:
| Type | Standard | Foundation | Building Code | Mortgage Treatment |
|---|---|---|---|---|
| Modular home | CSA A277 | Permanent (concrete) | Same as site-built | Same as site-built — full mortgage options |
| Panelized home | Provincial building code | Permanent | Same as site-built | Same as site-built |
| Manufactured home | CSA Z240 | Varies (may be on chassis) | Different standard | Restricted — fewer lenders, higher rates |
| Mobile home | Older standard or none | Not permanent (wheels/chassis) | May not meet current code | Very limited financing |
| Tiny home | Varies | Varies | Often no standard | Most lenders will not finance |
The critical distinction
CSA A277 (modular) = treated like a regular house. CSA Z240 (manufactured) = treated like a specialty product.
This single distinction determines whether you get a standard mortgage at competitive rates or face restrictions, higher costs, and limited lender options.
Modular home mortgages
Full mortgage eligibility
Modular homes built to CSA A277 standards qualify for:
| Feature | Availability |
|---|---|
| CMHC-insured mortgage (5% down) | Yes |
| Conventional mortgage (20%+ down) | Yes |
| 25-year amortization | Yes |
| 30-year amortization (first-time buyer, new build) | Yes |
| Competitive interest rates | Yes — same as site-built |
| HELOC | Yes |
| Refinancing | Yes |
| All Big 5 banks | Yes |
| Monoline lenders | Yes |
| Credit unions | Yes |
Requirements for full eligibility
| Requirement | Detail |
|---|---|
| CSA A277 certification | Factory must be certified; home must have CSA label/sticker |
| Permanent foundation | Concrete basement, crawlspace, or slab — no temporary or adjustable supports |
| Municipal permits | Same building permits as site-built homes |
| Appraisal | Standard appraisal; appraiser must confirm factory-built construction |
| Property ownership | You must own the land (not lease it) for most mortgage products |
Construction financing for modular homes
Since modular homes are built in a factory before delivery, the financing timeline differs from site-built homes:
| Phase | Financing | Details |
|---|---|---|
| Land purchase | Land mortgage or LOC | Buy the lot separately or include in construction financing |
| Factory build | Progress draws or builder deposit | Factory requires deposits during construction (typically 10–30–30–30%) |
| Delivery & install | Remaining construction funds | Transportation, crane, foundation connection |
| Completion | Convert to standard mortgage | Once home passes final inspection, convert to a standard mortgage |
Challenge: The gap between factory payments and mortgage funding. You may need bridge financing or a construction loan because the mortgage is not finalized until the home is complete and inspected on its foundation.
Modular home lenders in Canada
| Lender | Modular Home Mortgage | Notes |
|---|---|---|
| RBC | Yes | Standard terms; CSA A277 required |
| TD | Yes | Standard terms |

| First National | Yes | Through broker channel |
| Credit unions | Generally yes | Some are more experienced with factory-built |
Manufactured home mortgages
Restricted but possible
Manufactured homes (CSA Z240) face more barriers:
| Feature | Availability |
|---|---|
| CMHC-insured mortgage | Yes, with conditions |
| Conventional mortgage (20%+ down) | Yes, limited lenders |
| Minimum down payment | 5% (if CMHC-eligible) to 20%+ (uninsured) |
| Standard interest rates | Usually 0.25–1.0% higher than conventional |
| Amortization | Up to 25 years (some lenders cap at 15–20) |
| Big 5 banks | Limited — some branches in manufactured-home-heavy markets |
| Credit unions | Often the best option |
| B lenders | Available at higher rates |
CMHC requirements for manufactured homes
CMHC will insure manufactured homes if they meet all of the following:
| Requirement | Detail |
|---|---|
| CSA Z240 certified | Must carry the CSA certification label |
| Permanent foundation | Must be on a permanent, code-compliant foundation (not the original chassis) |
| Minimum floor area | Typically 500+ sq ft (varies by insurer) |
| Owned land | Must own the land — leased pad in a mobile home park may not qualify |
| Municipal zoning | Must be in an area zoned for manufactured housing |
| Good condition | Appraiser must confirm structural integrity |
Manufactured home lender options
| Lender Type | Down Payment | Rate Premium | Amortization | Notes |
|---|---|---|---|---|
| Credit unions | 10–20% | +0.25–0.50% | Up to 25 years | Often the best option for manufactured homes |
| B lenders | 15–25% | +0.50–1.50% | Up to 25 years | Higher rates but more flexible |
| Private lenders | 20–35% | +2.00–5.00% | Up to 15 years | Last resort |
| Chattel loans | 10–20% | +2.00–4.00% | Up to 20 years | For homes on leased land |
Chattel loans vs mortgages
If your manufactured home is on leased land (e.g., a mobile home park), you cannot get a standard mortgage because you do not own the real property. Instead, you need a chattel loan:
| Feature | Mortgage | Chattel Loan |
|---|---|---|
| Security | Real property (land + home) | Personal property (home only) |
| Interest rate | Lower (standard mortgage rates) | Higher (+2–4% above mortgage rates) |
| Amortization | Up to 25 years | Up to 15–20 years |
| CMHC insurable | Yes (if eligible) | No |
| Lender options | Many | Very few |
| Registering | Land titles office | Personal property registry |
Mobile homes
Very limited financing
Older mobile homes (pre-CSA Z240 or non-certified) have extremely limited financing options:
| Feature | Availability |
|---|---|
| Standard mortgage | No |
| CMHC insurance | No |
| Credit union financing | Sometimes — case by case |
| Chattel loan | Possibly, for newer models |
| Personal loan | Yes, but high rates and short terms |
| Cash purchase | Yes |
For mobile homes in parks, the typical financing path is a chattel loan or personal loan. Many buyers purchase with cash.
Cost comparison: modular vs site-built
| Cost Component | Site-Built | Modular | Difference |
|---|---|---|---|
| Construction cost per sq ft | $200–$350 | $150–$275 | Modular 15–25% less |
| Timeline | 8–18 months | 3–6 months | Modular 50–70% faster |
| Financing complexity | Standard construction mortgage | Factory payments + conversion | Modular more complex |
| Customization | Unlimited | Some limitations | Site-built more flexible |
| Quality control | Variable (weather, trades availability) | Factory-controlled | Modular more consistent |
| Mortgage rate | Standard | Standard (CSA A277) | Same |
| Resale value | Standard | Same as comparable site-built | Same |
Appraisal considerations
Appraising factory-built homes has unique challenges:
| Challenge | How It Is Handled |
|---|---|
| Fewer comparables | Appraiser may use site-built comparables for modular homes on permanent foundations |
| Stigma discount | Some markets apply a 5–10% discount for manufactured homes, even on permanent foundations |
| Depreciation | Manufactured homes may depreciate in some markets (unlike site-built); modular homes on owned land generally appreciate |
| Factory certification | Appraiser must verify the CSA label and confirm it is intact |
Tips for a successful appraisal
- Provide the CSA A277 or Z240 certification documentation to the appraiser
- Show the manufacturer’s specifications and warranty
- Ensure the permanent foundation is visible and documented
- Provide comparable sales of similar factory-built homes in the area if available
- Have building permits and inspection certificates ready
Provincial considerations
| Province | Manufactured Home Prevalence | Key Notes |
|---|---|---|
| British Columbia | High (especially rural and northern) | BC Housing provides resources; many credit unions specialize |
| Alberta | High (oilfield regions) | Strong manufactured home market; multiple lender options |
| Saskatchewan | Moderate | Credit unions active in this space |
| Manitoba | Moderate | Similar to Saskatchewan |
| Ontario | Moderate (northern and rural) | Growing interest in modular for affordability |
| Quebec | Lower | Usinées (manufactured) must meet Régie du bâtiment standards |
| Atlantic | Moderate | Manufactured homes common in rural areas |
Summary
| Home Type | Mortgage Access | Rates | Down Payment | Best Financing Route |
|---|---|---|---|---|
| Modular (CSA A277, permanent foundation) | Full access — same as site-built | Standard | 5%+ | Any lender |
| Manufactured (CSA Z240, permanent foundation, owned land) | Good but restricted | +0.25–1.0% | 10–20% | Credit unions, select B lenders |
| Manufactured (leased land) | Chattel loan only | +2–4% | 10–20% | Specialty lenders |
| Mobile home (older) | Very limited | +3–5% | 20%+ or cash | Personal loan or cash |
The key takeaway: if you are considering factory-built housing and want standard mortgage eligibility, ensure the home meets CSA A277 standards and is placed on a permanent foundation on land you own. This gives you identical mortgage options to a site-built home at the same rates.
