CMHC Prefab Plus: Eligibility, Staged Advances and Financing Questions for Prefabricated Homes
CMHC Prefab Plus is mortgage loan insurance for eligible prefabricated homes, including modular and manufactured homes in Canada. The program can finance different project stages, which matters when the land, site preparation, factory unit, delivery, and finishing costs are paid at different times. Program eligibility and loan insurance are not a guarantee of approval, a construction quote, or a promise that every cost will be funded.
CMHC’s public program page describes requirements for the borrower, new home, property, and loan. Those terms can change. This guide reflects the page viewed on September 26, 2026; confirm the current page and the lender’s written requirements before signing a purchase or construction contract.
Start by checking whether the project fits the program
The current CMHC page describes the homeowner product for eligible borrowers who are Canadian citizens, permanent residents, or non-permanent residents legally authorized to work in Canada. The home must be a new prefabricated home that meets applicable standards. The property must be in Canada, suitable and available for full-time, year-round occupancy, and have year-round vehicle access. A seasonal cabin, used home, or property with a difficult access arrangement may not fit these terms even if it is factory-built.
Ask the lender which certification applies to the specific home and province. “Prefabricated” is a broad description, and modular, manufactured, panelized, and other factory-built products can be treated differently under construction, title, and site rules. A factory certificate does not settle foundation, service connection, municipal inspection, property title, or lender documentation. Provide the lender the home plans, certification, site plan, contract, and expected occupancy use before paying a non-refundable deposit.
CMHC currently describes two financing paths. Prefabricated homes permanently affixed to land and placed on a permanent foundation may be eligible under standard underwriting criteria for a traditional mortgage. Movable homes not permanently affixed to land may be eligible through CMHC chattel financing and secured by a chattel mortgage. The program page says additional conditions apply; a lender must decide which path fits the property and borrower. Ask who owns the land, how the home will be titled, and what documents establish the home-to-land arrangement.
Understand the advance sequence
The program page lists staged advances for construction. The first advance can cover land acquisition and site-preparation costs such as excavation, foundation construction, and septic or well installation where required. A second advance covers the prefabricated unit cost on delivery. Third and fourth advances cover post-installation and finishing costs. This is helpful when a buyer must pay for a prepared site before the factory unit arrives, but it does not mean the lender will fund every invoice or release money on the date a contractor expects.
Ask the lender for the advance schedule, accepted invoices, inspection or appraisal requirements, draw fees, timing, holdbacks, and rules for paying contractors. Clarify whether the first advance includes land purchase, site preparation, or both, and how the lender values each stage. Ask what happens if the foundation is incomplete, the unit is delayed, or the final value differs from the planned amount. Keep a cash-flow table with each payment date, expected advance date, amount due, and source of funds.
The site contractor, factory, carrier, crane operator, installer, and finishing trades may have separate contracts. Coordinate their milestones with the lender’s inspections. A payment that is due before the next advance can create a cash gap, even where the total approved loan amount appears sufficient. Confirm in writing whether taxes, delivery, utility fees, permits, insurance, temporary accommodation, landscaping, or change orders are included.
Check borrowing limits and qualification terms
As of the date reviewed, CMHC lists homeowner loan-to-value limits up to 95% for one- to two-unit properties and up to 90% for three- to four-unit properties. The page also lists a maximum purchase price, lending value, or as-improved property value below $1.5 million for homeowner loans, a maximum amortization of 25 years, and a possible 30-year amortization through CMHC Home Start for eligible buyers. These are current program-page terms, not a promise of the amount a borrower can obtain.
The lender will still assess income, credit, debts, property value, down payment, and the planned project. CMHC’s page lists minimum credit and debt-service conditions and says the qualifying rate uses the greater of the contract rate plus two percentage points or 5.25%. Non-traditional down-payment rules are narrower than the general homeowner path. Ask the lender to identify the exact terms that apply rather than assuming that a maximum LTV or amortization is available in your case.
The insurance premium is a one-time charge based on loan-to-value tier and may be added to the insured loan. On the page reviewed, listed homeowner premiums range from 0.60% at the lowest tier to 4.00% at 90.01–95% LTV, or 4.50% for that tier with a non-traditional down payment. Ask for the dollar premium, whether it will be financed, the resulting payment, and any applicable tax. CMHC also describes a possible partial premium refund for eligible energy-efficient homes; confirm the separate eligibility and documentation before counting it as a saving.
Build a complete project budget
Separate land, factory unit, design or customization, site survey, clearing, grading, excavation, foundation, septic or well, utility connections, transport, crane or setting, module or section connection, weather seal, stairs, decks, appliances, inspections, finishing, permits, and restoration. For each contract, identify whether the work ends at delivery, set, connection, tested service, or ready occupancy. A staged financing program can support cash flow, but it does not turn an incomplete quote into a complete installed price.
Ask for allowances to name the condition that could change them. Soil, rock, groundwater, route access, crane reach, weather delays, utility extension, and local inspection can affect cost or schedule. If a price depends on a site report or authority approval, resolve that condition before the contract’s cancellation date. Keep contingency separate from optional upgrades so the owner can see what is necessary to reach occupancy.
Prepare a lender and project team checklist
Before committing, confirm:
- whether the home is new and which certification and provincial rules apply;
- whether the property qualifies for year-round occupancy and access;
- whether the loan will be a traditional mortgage or chattel mortgage;
- how the home and land will be titled and secured;
- what borrower, credit, down-payment, property-value, and debt-service tests apply;
- the current LTV, amortization, premium, tax, and any refund conditions;
- which contracts and invoices are eligible for each staged advance;
- what inspections, photographs, plans, permits, or completion documents release funds;
- who covers a payment that is due before an advance is available.
CMHC’s program is one financing route, not a general cost estimate for a prefab home. Compare lender offers using cash due, premium, interest, total scheduled payments, staging and draw terms, and the same site-to-occupancy scope. Confirm all terms directly with CMHC and the lender because eligibility and program details can change before closing.
Map each advance to a construction milestone
Create a cash-flow table with the advance stages on one axis and contractor payments on the other. Put the expected amount and due date for land, site preparation, foundation, septic or well, unit delivery, installation, finishing, utility connection, and inspection. Ask CMHC or the lender which of those lines the program will recognize and what proof it requires. A construction contract can request a deposit earlier than the lender’s first inspection or release, so identify that gap before making a binding commitment.
Confirm whether the advance amount is based on the invoice, appraised value, percentage completed, or a lender-reviewed cost. Ask about inspection fees, draw administration, holdbacks, and the time needed to release funds. If the factory delivery date changes, ask whether the advance schedule can move and what happens to interest, storage, or crane remobilization. Keep a cash reserve for costs that are excluded or arise after a site inspection.
An advance schedule is not an instruction to order every component as soon as money is available. Check the contract cancellation terms, construction sequence, warranty start date, and responsibility for damage if the unit waits on site. Coordinate the lender’s document review with the authority’s inspection and the contractor’s completion evidence. A missing report can delay funds even when physical work is nearly complete.
Compare the insured loan with the whole ownership budget
Mortgage insurance helps a lender accept an eligible loan structure; the premium is part of the borrower’s financing cost. Compare the principal, premium added to principal, interest over the expected term, cash down, taxes, property insurance, lot rent if any, maintenance, and ongoing utilities. If the premium can be added to the loan, the initial cash requirement may fall while the balance and interest cost rise. Ask the lender for both the financed and cash-paid version where allowed.
The program page’s maximum LTV or amortization is not the same as an approval amount. The property value, borrower profile, occupancy, unit count, current program conditions, and lender underwriting still control. If you depend on a non-traditional down payment or a maximum-LTV product, ask the lender to confirm the specific eligibility before relying on it. Also ask whether any energy-efficiency premium refund can apply, what evidence is needed, and when it is paid; do not subtract a possible refund from the closing budget before approval.
Resolve title, site, and certification questions before delivery
For the permanently affixed route, ask what definition of a permanent foundation the lender uses, how attachment and site completion are documented, and whether land ownership must be recorded in a particular way. For the movable-home chattel route, ask what title document secures the home and whether the site lease or other land use agreement must meet program terms. Confirm which party obtains provincial or municipal approvals and the inspections needed at factory, foundation, setting, utility connection, and occupancy.
If the home has multiple sections or uses a less common certification, send the certificate and plans to the lender early. Ask for written confirmation that the program path being considered applies to that type, not only to “prefab” generally. A factory label may establish one type of information but does not prove that the property is ready for year-round occupancy or that site work passed inspection.
