The appraisal gap nobody warns Ottawa condo buyers about

Ottawa's apartment benchmark is down 5.2%, and your lender noticed

OREB's July release came out on August 6 and most of it reads as steady. Sales up 0.2% year over year, the composite benchmark holding at $634,000, months of inventory creeping from 3.3 to 3.5.

Then you get to the apartment section.

The condominium apartment benchmark is down 5.2% from a year ago. Apartments carry 5.4 months of inventory against 3.2 for single-family homes. Sales-to-new-listings came in at 41.0%, and the median unit took 41 days to sell.

That is a full year of falling values in one segment while the rest of the market went sideways. Which brings me to something I have had to explain three times in the last month, and every time the buyer was surprised.

Your lender does not lend against the price you agreed to pay.

What the lender is actually underwriting

When you sign an agreement of purchase and sale, you and the seller have settled on a number. Your lender treats that number as one input, not the answer. The mortgage is sized against the lesser of the purchase price and the appraised value.

When those two match, nothing happens and you never think about it again. That was most of 2021 and 2022 in Ottawa, when appraisers pulled comparables from a rising market three months back and the value came in at or above contract every time.

Run it the other direction and the arithmetic gets uncomfortable fast.

Say you are buying a $500,000 condo with 20% down. You have budgeted $100,000 and you are financing $400,000. The appraisal comes back at $475,000, a 5% haircut, roughly the move the apartment benchmark has already made in twelve months.

Your lender will now advance 80% of $475,000. That is $380,000.

You are $20,000 short, in cash, before closing. Your down payment just went from $100,000 to $120,000, or 24% of the price. And nobody warned you, because the appraisal is usually ordered after your conditions have come off.

The buyers with more money are the ones exposed

Here is the part that surprises people, and it is worth knowing before you decide how much to put down.

Put under 20% down and your mortgage has to be insured through CMHC, Sagen, or Canada Guaranty. The insurer runs its own valuation, usually an automated model rather than a person walking the unit. On most insured deals no physical appraisal gets ordered at all, and if the insurer wants one, the insurer pays for it.

Put 20% or more down and your mortgage is conventional. No insurer, no automated backstop, and your lender orders a real appraisal. That is the one that can come in short.

So the buyer with 10% down frequently sails past a valuation check that the buyer with 20% down walks straight into. That is backwards from how most people assume risk works.

Where the gap actually shows up in Ottawa

Three situations, in the order I run into them.

Downtown apartment resales. Ottawa Centre sits at 5.6 months of inventory, a 39.6% sales-to-new-listings ratio, sales down 8.3%. Thin recent sales plus falling comparables is the recipe for a conservative appraisal.

Pre-construction closings. If you signed in 2021 or 2022 and your building is finishing now, you agreed to a price set by a market that no longer exists. Ottawa has a lot of apartment product completing right now, which I got into in completions outpacing starts. Your builder will not adjust the price. Your lender will adjust the loan.

Anything without close comparables. Odd layouts, a unit type nothing else in the building matches. Appraisers get conservative when the comparable set is thin, and conservative means low.

The nineteen percent move most buyers never hear about

If the appraisal comes in short and you cannot find the cash, the options people know about are renegotiate, borrow the difference, or walk. There is a fourth, and it works precisely because of the insured versus conventional split above.

Put less than 20% down on purpose.

Same $500,000 condo. Put 19% down, which is $95,000. You are borrowing $405,000, an 81% loan to value, so the mortgage is legally required to be insured. The premium at that tier is 2.80%, or $11,340, and it gets added to the mortgage rather than paid up front. Ontario charges 8% PST on the premium and that piece is cash at closing, which comes to $907.

Compare the two. The conventional route after a low appraisal needs $120,000 on closing day. The insured route needs $95,907. You keep $24,093.

It is not free. Your mortgage is $416,340 instead of $380,000, and at 4.04%, the best five-year fixed posted this week, that is about $192 a month more on a 25 year amortization. Insured borrowers usually get a slightly better rate, so the real gap is a bit narrower. The route also has limits: owner-occupied only, under $1.5 million, and amortization capped at 25 years unless you are a first-time buyer or it is a new build.

I am not telling you which side of that trade to take. I am telling you the option exists, because most buyers hear about it from a broker at eleven at night, four days before closing.

Write the financing condition like it matters

The financing condition is what protects you here, and boilerplate wording does not always do the job. A condition on "the buyer obtaining financing" can be argued as satisfied if any lender approves you at all, even for less than you need.

You want it to reference financing satisfactory to the buyer in the buyer's sole discretion, in an amount sufficient to complete, and you want the condition period long enough for the appraisal to actually happen. Five days is not long enough. Sort the wording out with your lawyer before you sign, not after.

And if you are thinking about waiving financing to win a deal, look at the market you are in. Ottawa sold at 97.8% of list in July with a median of 28 days on market. That is not a market demanding you strip conditions off your offer. The same logic I used on the wait-for-a-rate-cut argument applies here.

Walking away is the most expensive door in the room

If the gap opens and you have no condition to fall back on, you cannot simply leave. In Ontario the seller keeps the deposit and can then sue for the difference between your price and whatever the property eventually resells for, plus carrying costs, plus a second commission, plus legal fees. Courts enforce it.

On a $500,000 condo that resells for $475,000, a forfeited $25,000 deposit is the opening line of the bill, not the total.

All of it is avoidable with an appraisal-aware condition and a broker who orders the valuation early. Cheap to plan for, expensive to discover.
