If you’ve been dreaming of a peaceful escape nestled among Ontario’s lakes and forests, prefab cottages offer a faster, cost-effective alternative to traditional construction.
However, when it comes to financing, especially your down payment, things can get complicated—fast.
Today, we’ll break down the minimum down payment requirements for prefab cottages in Ontario, explain what lenders really look for, and give you insider strategies to qualify for the best terms.
How Much Down Payment Do You Need for a Prefab Cottage in Ontario?
The short answer: it depends on how the property will be used, where it’s located, and whether your build qualifies under CMHC insurance guidelines.
Here’s a breakdown:
| Type of Property | Typical Down Payment | Key Conditions |
|---|---|---|
| CMHC-Eligible Prefab Home (Year-round, CSA-A277 compliant) | 5–10% | Must be principal residence, on titled land, meet building codes |
| Seasonal Cottage (Uninsurable, remote access, or three-season) | 20–25% | No CMHC support; lender risk = higher deposit |
| Land-Only Purchase (Before building) | 35–50% | Often requires private or alternative financing |
What Should I Know About Down Payments for Ontario Prefab Cottages?
🗣️ “Most buyers are surprised they can’t just do 5% down. The key is proving the build is a livable, year-round dwelling,” says Daniel Reid, licensed mortgage broker at over 12 years of experience financing custom prefab homes in Ontario.
Whether your dream is a cozy tiny home, a guest house for extended family, or a high quality product like a CSA-certified prefab cottage, understanding lender risk is crucial.
Rural builds and off-grid lots typically carry higher financing barriers, regardless of your square footage or budget.
CMHC-Insured vs. Conventional Financing Requirements
CMHC (Canada Mortgage and Housing Corporation) allows 5% down on modular homes that meet stringent criteria:
Must be permanent, year-round homes
Compliant with CSA-A277 building technique
Connected to utilities and built on a permanent foundation
Located on zoned land with a registered title
This is where choosing the right prefab builder pays off.
Companies like My Own Cottage specialize in floor plans that meet CMHC specs, offering clients faster paths to approval, reduced interest rates, and peace of mind.

Down Payment Rules for Land-Only and Seasonal Properties
If you’re buying land first or building a vacation home that isn’t winterized, CMHC won’t insure it.
Importantly, this means you’ll need a conventional mortgage—and those often come with:
35–50% down for land-only purchases
20–25% down for seasonal-use prefab cottages
Additional conditions like secondary appraisals or cost-to-complete statements
A customer in Muskoka shared their story: “We found our perfect home design, but didn’t realize our land-only loan needed 40% down. Thankfully, My Own Cottage helped us bundle land + build into a single loan product that saved us over $35,000.”
