You’ve found the perfect rustic cottage in Tiny Township. It’s tucked away at the end of a quiet dirt road, warmed by a charming woodstove, and offers breathtaking views of Georgian Bay. You’re ready to make an offer and head to the bank for mortgage pre-approval, expecting to put down just 5%. But then you hit a snag. That cozy woodstove and the lake water source might mean your dream cottage is classified as a "Type B" property—and that changes everything about your mortgage.
This post explains what the Type B property trap is, why lenders treat these cottages differently, and how you can navigate the financing challenges to secure your dream getaway.
The Two Types of Cottage Properties Lenders Recognize
Lenders don’t see all cottages the same way. They generally split them into two categories: Type A and Type B. Understanding these categories before you make an offer can save you thousands of dollars and a lot of frustration.
Type A: The Second Home
Type A cottages are essentially houses by the lake. They meet most of the standards lenders expect for a residential property.
Foundation: Permanent, such as concrete or full basement
Heating: Central heating system like forced air furnace, baseboards, or heat pump. A woodstove is just for ambiance.
Water: Potable water from a well or municipal supply
Road Access: Publicly maintained and plowed year-round
Mortgage implications:
You can usually get a mortgage with as little as 5% down and qualify for the best residential interest rates.
Type B: The True Cottage (Seasonal)
Type B cottages are the rustic escapes many imagine when thinking about a cottage getaway. They often lack permanent infrastructure.
Foundation: May be on piers, blocks, or floating foundations
Heating: No central heating; relies on woodstoves, fireplaces, or space heaters
Water: Often draws water directly from the lake, which is not potable without filtration
Road Access: Private or seasonal roads, often not plowed in winter
Mortgage implications:
Lenders see these as higher risk. You’ll likely need a larger down payment, usually between 10% and 20%. Interest rates may be 0.10% to 0.25% higher than standard mortgages.

Why Lenders Treat Type B Properties Differently
Lenders base their decisions on risk. Type B cottages often lack the permanent features that make a property easier to insure, maintain, and resell. Here are some reasons why lenders are cautious:
Foundation concerns: Non-permanent foundations can lead to structural issues or damage from weather.
Heating risks: Woodstoves and fireplaces don’t provide consistent heat, increasing the risk of damage or uninhabitability during cold months.
Water safety: Lake water is not guaranteed safe to drink without filtration, raising health and safety concerns.
Road access: Seasonal or private roads may be inaccessible during winter, affecting property value and emergency access.
Because of these factors, lenders see Type B cottages as riskier investments. They protect themselves by requiring higher down payments and charging slightly higher interest rates.
The Hidden Deal-Killers in Type B Cottage Financing
Even if you have the 20% down payment for a Type B cottage, the property itself must meet certain standards to qualify for a mortgage. Some common deal-killers include:
Lack of potable water: If the cottage draws water directly from the lake without filtration, lenders may refuse financing.
No permanent foundation: Some lenders won’t finance cottages on blocks or piers.
Seasonal road access: If the road isn’t maintained year-round, it can be a red flag.
No central heating: Relying solely on a woodstove can disqualify the property from standard mortgage programs.
Before making an offer, ask your lender what their specific requirements are for Type B properties. Some lenders specialize in these loans and may offer more flexible terms.
How to Prepare for Financing a Type B Cottage
If your dream cottage falls into the Type B category, here are steps to improve your chances of mortgage approval:
Increase your down payment: Aim for at least 20% to show lenders you’re serious and reduce their risk.
Get a professional inspection: Confirm the foundation and heating systems meet safety standards.
Consider upgrades: Installing a permanent heating system or a potable water source can reclassify your cottage as Type A.
Work with specialized lenders: Some credit unions or smaller banks have programs tailored for seasonal cottages.
Be ready for higher interest rates: Budget for slightly higher mortgage costs due to increased lender risk.
Real-Life Example: How the Type B Classification Affected a Buyer
A couple found a charming cottage on a private road with a woodstove and lake water. They planned to put 5% down and expected a standard mortgage rate. When they applied, the bank classified the property as Type B and required a 15% down payment plus a higher interest rate. The couple decided to negotiate with the seller to cover some closing costs and saved by choosing a lender specializing in seasonal properties. They also installed a filtration system for the water, improving the cottage’s value and comfort.
What This Means for Your Cottage Search
Knowing the difference between Type A and Type B properties can save you time and money. If you fall in love with a rustic cottage, check the heating, foundation, water source, and road access before making an offer. Talk to lenders early to understand their requirements and prepare your finances accordingly.
Your dream cottage might need some upgrades or a bigger down payment, but with the right knowledge, you can avoid surprises and secure financing that fits your goals.
