If the word appraisal is making you nervous, here is the reassuring part first: a low appraisal does not usually kill a deal. What it does is create a gap you have to fill with cash. Lenders lend against the lower of the purchase price and the appraised value, so if you agreed to $700,000 and the appraisal says $670,000, the lender quietly starts doing its arithmetic on $670,000 and the $30,000 difference becomes yours to cover. So here is why it happens, what your options genuinely are, and how to protect yourself before it does.
Why the lender orders an appraisal at all
The lender is not curious about your taste in houses. If you stopped paying, the property is what they would be left holding, and the appraisal is their independent opinion of what it would fetch. That is also why the appraiser works for the lender rather than for you, even though you often pay for it, and why your enthusiasm for the place has no influence at all on the number.
Not every purchase gets a full appraisal. Many insured mortgages on standard properties in active markets are valued by an automated system instead, which is faster and cheaper. A full appraisal gets ordered when the property is unusual, the market is thin, the price looks out of line, or the lender simply requires one for that product. Rural homes, acreages and character houses almost always get a real appraiser through the door.
What low actually does to your financing
The lender applies your loan-to-value against the lower of the price and the value. Here is the mechanic, with illustrative numbers. You are buying at $700,000 with twenty percent down, so a $560,000 mortgage and $140,000 of your own money. The appraisal comes in at $670,000. The lender will now lend eighty percent of $670,000, which is $536,000. You still owe the seller $700,000. The cash you need has just gone from $140,000 to $164,000.
Notice what did not happen there. Nobody said no. The approval is still sitting there, just smaller. That distinction really matters, because the panicked response is usually that the deal is dead, when the actual question is where $24,000 comes from, or what else changes.
A low appraisal rarely cancels an approval. It shrinks one, and hands you the difference in cash.
Your five options
Bring more cash. The simplest route, and often what happens where the gap is small. Do check where the money is coming from, since lenders need to trace it.
Renegotiate with the seller. An appraisal is third-party evidence and sellers do listen to it, particularly in a slower market. Quite often you meet in the middle.
Challenge the appraisal. Possible, though not easy. You need genuine errors: comparables that were not truly comparable, a basement suite that was missed, square footage measured wrong, renovations not accounted for. Disagreeing with the conclusion is not grounds on its own.
Try a different lender. Different lenders use different appraisers, and some order none at all on a given file. This is less about shopping for a friendlier number than recognising that one opinion is one opinion.
Walk away. Open to you only while a subject to financing condition is still in place, which is the entire reason that condition exists.
Why appraisals come in low
A rising market is the classic cause. Appraisers value on the basis of completed sales, and in a fast market those sales are already stale by the time they close. If you paid over asking in a bidding war, you may have paid tomorrow's price while the appraiser is working from last month's evidence.
A thin market is the other big one, and that is very much a small-town British Columbia problem. If only four comparable homes sold in your area over the past year and none of them really match the property, the appraiser is making a judgement call with limited data. Rural acreage, waterfront and unusual homes all have this issue. It is not an insult to the property, it is a shortage of evidence.
Then there are the property-specific reasons: maintenance that was put off and hidden well by the seller's photographs, a suite that is not legal, an oddity in the zoning, or a home improved well beyond its neighbourhood. That last one catches renovators regularly. Spending $200,000 on a home in a street of $400,000 homes rarely produces a $600,000 appraisal.
Refinancing is a different kind of pain
When you refinance there is no purchase price to anchor to, so the appraisal is the whole basis of how much you can borrow. A value that comes in $50,000 under what you expected directly reduces the equity you can reach, and there is no seller to renegotiate with. This is where somebody planning a renovation or a debt consolidation discovers the plan does not quite fit, which is why I prefer to be conservative about value estimates before anybody gets attached to a number.
How to protect yourself
Keep your subject to financing condition. In a competitive market there is real pressure to drop it, so understand exactly what you would be giving up. Without it, a low appraisal means finding the cash or losing your deposit.
Give yourself enough days. An appraisal can take a week or more to schedule and report on a rural property, so a five day financing condition on an acreage is optimistic.
Be realistic before you offer. If you are stretching to the very top of your approval on the minimum down payment, a low appraisal has nowhere to land.
Help the appraiser. Leave a list of recent upgrades with dates and costs, make sure they can reach every part of the property, and mention any comparable sales you know of.
Talk to your broker before you write the offer. On an unusual property I would far rather flag the appraisal risk in advance than explain it afterwards.
A word about subject-free offers
I understand entirely why people write them, and in some markets it is the only way to win. A subject-free offer on a property nobody has valued is a genuine financial risk though, rather than a technicality. If you are considering one, the honest sequence is to talk to your broker first, understand your absolute ceiling in cash, and know what happens if the value lands five percent light. Going in with your eyes open is a very different thing from finding out afterwards.
Questions people ask me
Who pays for the appraisal?
Usually the borrower, though some lenders cover it as part of a promotion or absorb it on insured files. The cost varies with the property type and the location, and rural properties generally cost more, since the appraiser has further to drive and fewer comparables to work from.
Can I see the appraisal report?
Sometimes. The appraisal is prepared for the lender, so it is their report. Many lenders will share it with you, particularly where you paid for it, though you are not automatically entitled to a copy.
Can I use my own appraiser?
Usually not. Lenders order from their own approved panel specifically so that the appraiser is independent of the transaction. An appraisal you commission yourself can be useful information for you, and it generally will not be accepted for financing.
Does a low appraisal mean I overpaid?
Not necessarily. It means the evidence available at that moment did not support the price, and in a rising or a thin market those can be quite different things. It is still worth taking seriously as a data point.
How long is an appraisal good for?
Typically a few months, though lenders vary and a fast-moving market can shorten it. If your closing is a long way out, or your deal falls apart and restarts, expect to need a new one.
The appraisal is the step where the most deals wobble and the fewest people understand what is actually happening. If you are buying something unusual, something rural, or something at the top of your range, it is worth talking the appraisal risk through before you write the offer rather than after. And if you are still working out your number, the affordability calculator is a reasonable place to start.
