Can you get a mortgage on a prefab house in Canada?

“Can you even get a mortgage on a prefab house in Canada?”

If you’re asking that question, you’re probably already serious about buying one. Prefab homes are modern, affordable, and quicker to build than traditional houses. But financing them can feel like walking through a maze of lender rules, inspections, and requirements you’ve never heard of.

Here’s the good news: yes, you can get a mortgage for a prefab home in Canada but there are some important steps to make sure the bank says yes. In this guide, we’ll break down exactly what lenders look for, the types of mortgages available, and the common pitfalls you’ll want to avoid. By the end, you’ll know how to confidently approach financing your prefab dream home.

Mortgage Eligibility for Prefab Homes

Not every prefab or modular home automatically qualifies for a mortgage. Lenders treat them differently depending on how they’re built, certified, and attached to land. But yes many prefab homes can qualify, as long as you meet certain criteria.

Here are key lender requirements and considerations:

1. Certification & Building Standards

• CSA Certification (A-660 or equivalent): Many Canadian lenders require that your prefab home meets national factory-built standards (for instance, CSA A660). 
• Code compliance: The home must meet local building codes (structural, electrical, plumbing) just like any site-built house.
• Quality control records: Inspections, factory documentation, and step-by-step build records help lenders assess risk.

2. Permanent Foundation & Land Ownership

• Affixed to a permanent foundation: The home must usually be on a concrete slab, basement, or engineered footings not on wheels or skids.
• Land must be owned or purchased with the home: If the land is leased (for example, in a mobile home park), lenders are more reluctant. In those cases, they may require a “chattel mortgage” instead of a traditional mortgage.
• Lease term matters: If land is leased, the lease duration often must exceed the mortgage term plus amortization period.

3. Appraisal & Valuation

• The property (land + prefab structure) must be appraised much like a regular home.
• The appraiser assesses foundation, materials, finishes, and comparable.
• If the prefab structure is viewed as “personal property,” that lowers value in a lender’s eyes.

4. Credit, Down Payment, Income & Risk

• You’ll need a solid credit history and stable income often similar standards to traditional mortgage applicants. 
• Down payment may be higher for prefab homes, especially if they’re smaller or non-standard.
• Some lenders see prefab homes as riskier, so they may require more documentation, stricter underwriting, or higher interest premiums. 

5. Insurance & Mortgage Insurance Rules

• The home must be insurable; lenders need proof that an insurer will cover it.
• If you want to use CMHC-insured mortgages (or other mortgage insurance programs), your prefab home must satisfy the same standards as stick-built homes (foundation, code compliance, classification as real property).

6. Builder Reputation & Documentation

• Lenders prefer experienced, reputable builders with a track record in prefab or modular construction.
• You’ll need thorough documentation: building contracts, specifications, warranties, factory plans, etc.

Types of Mortgage Options Available

When financing a prefab home in Canada, you don’t have just one path. The right option depends on your timeline, how much work is left, and how the house is being built. Here are the common mortgage types you should know about:

1. Traditional (Purchase) Mortgage

• This is the same mortgage you’d get for a regular home ,once the prefab is complete and installed on its permanent foundation.
• If the home is being delivered and assembled quickly (within about 120 days), many lenders will treat it like a standard home purchase.
• You make a down payment, get approved based on income/credit, and the lender issues a mortgage on the finished property.
• With recent rule changes, insured mortgages for newly built homes may allow amortization up to 30 years (versus the traditional 25).

2. Construction / Draw Mortgage (Progress-Advance Lending)

• This type is used when you’re building or assembling the home in stages. You receive funds (draws) at milestones. 
• During construction, you typically pay interest-only on the amounts released; full mortgage payments begin once the home is completed. 
• The insurer Sagen offers a Progress Advance Program that supports insured advances during construction. It covers prefab homes built to acceptable standards.
• Draws are tied to work completed (e.g. foundation, framing, mechanicals). The lender or insurer may inspect or verify progress before releasing funds.

3. Completion Mortgage (or Turn-Key / Deferred Loan)

• In some deals, you lock in your mortgage commitment now but don’t start payments until after construction.
• You sign a purchase agreement, make a deposit, and the mortgage is finalized when the home is ready. 
• This avoids multiple draws and complex interim payments. It’s often simpler for buyers who don’t want to manage construction cash flow.

4. Insured Mortgages (CMHC, Sagen, Canada Guaranty)

• To lower down payment barriers, you can use mortgage insurance (e.g. via CMHC, Sagen) if your prefab home meets the same standards as traditional homes.
• Some construction draws or progress advances are insured under programs like Sagen’s Progress Advance. 
• Insured mortgages can allow you to put down as little as 5%, but you’ll pay a mortgage insurance premium.
• Insurability requires the property to comply with building codes, and the prefab to be treated as real property (not personal property).

Common Challenges and Limitations

Even though mortgages are possible for prefab homes, there are hidden hurdles that can trip you up. Knowing them ahead of time helps you prepare.

1. Lenders Treat Prefab Differently

• Some lenders don’t see all prefab homes as “real property.” They may treat parts as “personal property” (like appliances) and refuse full mortgage treatment.
• Manufactured or mobile homes (especially older ones) often get stricter scrutiny or be excluded from traditional mortgage rules. 
• Tiny homes or very small prefab units may not meet minimum size thresholds that many lenders require.

2. Documentation & Certification Gaps

• Lenders usually demand CSA certification (e.g. A-660) or proof of compliance with building codes. Missing or weak documentation can stall approval. 
• Detailed blueprints, factory build records, and inspections must often line up. If something is missing or inconsistent, many lenders reject the application.
• Permit and zoning compliance is critical. If your plot or municipality doesn’t legally allow prefab or modular structures, you may hit a wall.

3. Higher Down Payments & Stricter Terms

• Because prefab builds are sometimes seen as higher risk, lenders may require larger down payments or ask for extra “cushion.”
• Interest rates or underwriting margins may be less favorable for prefab houses, depending on lender comfort level.
• Mortgage insurance (e.g. via CMHC or private insurers) may not always be available unless all standards are met.

4. Timeline & Construction Delays

• Prefab homes are built in factories and then transported and assembled. Delays in factory production, transport, or municipal inspections may slow your timeline.
• Lenders offering “construction mortgages” or draw financing may refuse to release funds until milestones are verified. If verification is late, your funding may lag.
• If your project stalls, you may incur extra carrying costs (site preparation, interest, storage).

5. Appraisal & Resale Risk

• Appraisers may struggle to find comparable sales (“comps”) for prefab homes in your region. That can reduce the appraised value and lower how much the lender is willing to finance.
• Some buyers worry prefab homes don’t appreciate as consistently as traditional homes, especially in areas where prefab housing is less common.
• If you decide to sell, potential buyers or lenders may again scrutinize certifications, foundation, or documentation.

Best Practices to Secure Financing

Here are proven strategies and tips (backed by industry experience) to improve your chances of getting a mortgage for a prefab home in Canada:

1. Start with Pre-Approval & Full Disclosure

• Before placing an order or signing a builder contract, get pre-approved by a lender familiar with prefab homes.
• Be upfront: tell the mortgage officer this is a factory-built home, not a standard stick-built house.
• Many lenders reject or delay applications when they learn late in the process that the home is prefab.
• Pre-approval gives you clarity on what you qualify for and what requirements your lender needs.

2. Partner with a Mortgage Broker or Specialist in Prefab Financing

• Brokers often know which lenders are prefab-friendly or have special criteria.
• They can match your project to lenders more likely to approve your case.
• A specialist can guide you through unique documentation, inspections, or underwriting requests.
• For example, some lenders treat factory-built/mobile/modular homes differently depending on foundation type, condition, classification, etc. 

3. Work with Recognized & Reliable Builders

• Choose a builder or prefab manufacturer with a strong track record of delivering compliant homes.
• Lenders prefer projects where the builder provides documentation, certification, warranties, and has industry reputation.
• The more transparent the builder’s process (factory records, inspections, test results) the better in the eyes of lenders.

4. Ensure All Regulatory & Technical Compliance

• Certifications & codes: Make sure your home meets national or provincial factory standards (e.g. CSA or equivalent) and local building codes.
• Permanent foundation: Lenders often require a permanent foundation (concrete, footing, basement) rather than temporary blocks or piers.
• Utilities & services: Ensure water, sewer, electrical, heating, and access roads meet municipal standards. 
• Condition & age: Newer prefab homes or those with sound structural health fare better. Older or deteriorating ones may be harder to finance. 

5. Prepare Strong Documentation

Lenders may ask for:

• Factory build plans, drawings, and specs
• Builder contracts, agreements, and warranties
• Inspection reports, quality control logs, and site photos
• Appraisal of land + structure
• Proof of foundation, soil report, permits, and zoning compliance
• Any factory certification or stamping documents

Having all of these organized goes a long way in smoothing underwriting.

6. Be Ready for Higher Down Payments & More Rigid Terms

• You may need to put down more than a standard mortgage requires especially if the home or project is non-standard.
• Lenders might limit amortization (e.g. shorter term) if they see risk in the prefab aspect.
• Be prepared for stricter scrutiny on your credit, income, and other ratios.

7. Negotiate Progress Advances Carefully

• If your financing involves draw payments during construction, make sure your schedule is realistic and matches builder milestones.
• Agree in writing what evidence or inspections trigger each payment.
• Delays or mismatches can stall draws, which can stall your project.
• Lenders/insurers (e.g. via progress advance programs) may require verification before each draw.

8. Maintain Clean Communication & Transparency

• Keep your lender informed at each stage: factory build, shipment, delivery, site prep, assembly.
• Document delays, changes, or modifications promptly.
• If something deviates from the initial plan, alert your underwriter early, so they can assess instead of surprise-reject.
