Every September I get the same call. A family gets back from two weeks at a rented place on the lake, the kids are already asking about next year, and someone says out loud: “why are we paying someone else for this?”

Last fall it was a couple who had already been pre-approved through their bank. They’d been told 5% down, they’d found a place they loved north of Parry Sound, and they called me because their bank had gone quiet on them a week before the offer deadline. The problem wasn’t their income or their credit. It was the property. Seasonal road, water from the lake, wood stove for heat. Nobody had told them that changes everything. We ended up funding it a different way — a HELOC on their primary home for the down payment, and a lender who was comfortable with the property once we documented it properly. They got the cottage. But they got it three weeks later and with a lot more of their own money in the deal than they’d planned.

If a cottage is on your mind this fall, here’s what actually determines whether it happens.

The property decides your down payment, not you

For a second home, the insured minimum down payment is the same as it is on the home you live in: 5% of the first $500,000 and 10% on the portion above that, up to a purchase price just under $1.5 million.

That’s the good news, and it surprises people. The catch is that those insured rules only apply if the property qualifies — and a lot of cottages don’t.

Lenders sort recreational properties into two buckets. The first is essentially a house that happens to be on a lake: year-round road access, a permanent heat source, a drinkable water supply, a normal kitchen and bathroom, a normal size. That one can go insured.

The second bucket is everything else, and it usually gets pushed there by one of these:

• seasonal road access
• water access only
• square footage below the lender’s minimum
• the drinking water supply
• the heat source

Any one of those can move you out of the insured world entirely.

The sliding scale is the number nobody warns you about

Once you’re outside insured lending, you don’t just default to “20% down.” You land in a world where the lender decides how much of the purchase price they’re willing to lend against — and it slides down as the price goes up.

It looks something like this. A lender might do 80% of the first $750,000 and only 50% of everything above that. Another might go 80% up to $1 million, or up to $1.5 million, and then start sliding on the amount above.

Run that on a $900,000 cottage at 80/50 with a $750,000 break: they’ll lend $600,000 on the first $750,000 and $75,000 on the remaining $150,000. That’s $675,000 — so you need $225,000 down, not $180,000. Same buyer, same income, same rate. A $45,000 difference created entirely by where the property sits and what it’s worth.

How aggressive that scale is depends on the region, the population around it, and local property values. Two lakes an hour apart can produce two very different answers.

This is the single most common reason a cottage deal dies. Not income. Not credit. The buyer simply doesn’t have enough down payment to meet the sliding scale, and they find out late.

Where the down payment actually comes from

Here’s the trap I see most often: people assume their FHSA or the RRSP Home Buyers’ Plan is part of the plan. Neither one applies here. Both are for a home you’re going to live in as your principal residence. A cottage is not that.

So the money almost always comes from one of four places:

• Equity in the home you already own. A HELOC or a refinance is how most cottages get funded. You can generally get to 80% of your home’s value in total borrowing, with a maximum of 65% in the revolving HELOC portion.
• Non-registered investments. Straightforward, but watch the tax hit on what you sell and give yourself time for the funds to settle and season.
• A gift from immediate family. Allowed, and it needs a gift letter.
• A blended increase on your existing mortgage. Sometimes cleaner than a new HELOC, depending on your current rate and term.

The right one depends on your current mortgage, your rate and how long you plan to keep both properties. That’s a 20-minute conversation, and it’s worth having before you’re in a bidding situation.

“We’ll rent it out to cover it” — read this part carefully

I understand the appeal. It’s also the fastest way to lose the deal.

No lender will accept short-term rental income on the property you’re buying. And it’s worse than that: if it comes out that the plan is to run it as a short-term rental, most lenders will decline the property outright. Not “we won’t count the income” — they won’t lend on it at all.

There is a narrow exception, and it’s on the other side of the fence. If you already own a different property with a two-year documented history of short-term rental income, and the lender you’re applying to isn’t the lender on that property, some will let us use that income. It’s an exception, not a plan.

So the qualifying question is simple and unforgiving: can you carry two mortgage payments, two sets of property taxes, two insurance policies and the maintenance on both? That’s the test.

Other things that quietly kill cottage files

• No flushing toilet. Composting or outhouse setups are a hard stop for most lenders.
• A kitchen or bathroom that isn’t a traditional setup.
• Heat. If a fireplace or a wood-burning stove is the only heat source, that’s a problem — for the lender and, separately, for your insurer.
• Leasehold land. If you don’t own the land under the cottage, that alone can end the conversation with most lenders.
• Location bias. There are regions where certain lenders simply won’t lend, regardless of the buyer or the property.
• Thin appraisal comparables. On a quiet lake, the appraiser may have very little recent sales data to work with, and the value can come in short.

What to do before you fall in love with a listing

Get the property details first: how you reach it in February, where the water comes from, how it’s heated, the square footage, whether the land is owned, and whether the toilet flushes. Those six answers tell me more about your financing than your income statement does.

Then we work backwards to the down payment you’ll actually need — including the sliding scale — and figure out where it’s coming from. Do that in September and you’re ready to move when the right place shows up. Do it after you’ve made an offer and you’re negotiating with a clock running.
