In most cases, an appraisal is used to protect the lender, not to confirm whether a buyer feels good about the price. A bank or mortgage lender wants to know that if it lends against a property, the value supports the loan amount. If the borrower defaults, the property is the lender's security.

That is why an appraisal often comes up when a buyer is getting a mortgage. It can also be ordered when a homeowner is refinancing, applying for a home equity line of credit, settling an estate, or dealing with a separation where property value needs to be documented.

A common point of confusion is the difference between an appraisal and a market evaluation from a Realtor®. A real estate professional provides a pricing opinion based on current market conditions, comparable sales, buyer demand, and strategy. An appraiser provides an independent valuation, usually for lending or legal purposes, following formal valuation methods and reporting standards. They are related, but they are not the same thing.

Usually, the lender orders it. Even though the buyer or homeowner often pays the appraisal fee, the appraiser is generally working on behalf of the lender. That independence matters because the lender wants an unbiased opinion, not one influenced by the buyer, seller, or agent.

In some situations, a private appraisal can be ordered directly by a homeowner, lawyer, or accountant. That tends to happen outside the typical mortgage process, such as for estate planning, divorce proceedings, tax matters, or personal financial planning.

For a standard home purchase, though, buyers usually do not choose the appraiser themselves. The lender or mortgage broker arranges it through an appraisal management company or directly with an approved appraiser.

How does an appraiser determine value?

This is where the process becomes more detailed than many people expect. An appraiser does not simply walk through the home and pick a number. They look at the property itself, but they also compare it to recent sales and current market behaviour.

The main factors usually include the home's location, lot size, square footage, layout, age, condition, updates, number of bedrooms and bathrooms, basement finish, garage space, and overall appeal. They also consider recent comparable sales nearby, especially homes that are similar in style, size, condition, and neighbourhood.

If two detached homes are both in Durham Region, but one backs onto a busy road, and the other sits on a quiet court near good schools, that difference can affect value. If one has a renovated kitchen and updated mechanical systems while the other needs major work, that matters too.

Appraisers typically rely most heavily on the sales comparison approach for residential properties. That means they look at recently sold homes and make adjustments for differences. In some cases, especially for unique properties or investment real estate, they may also consider cost or income approaches, but for most houses and condos, comparable sales carry the most weight.

What happens during the appraisal process?

The process is usually fairly quick, but timing can vary depending on the lender, property type, and market conditions. After the lender orders the appraisal, the appraiser may complete a full interior visit, a drive-by appraisal, or a desktop appraisal, depending on the circumstances.

For a full appraisal, the appraiser schedules a visit to the property. They measure, photograph, and observe the home's condition, layout, finishes, and upgrades. They are not judging housekeeping, but presentation still helps because clutter or deferred maintenance can make the condition harder to assess.

After the inspection, the appraiser reviews market data, studies comparable sales, makes adjustments, and prepares a report. That report goes back to the lender, not usually directly to the buyer or seller unless the lender chooses to share it.

The turnaround can be a couple of days or longer in busy periods. If a closing is tight, appraisal timing matters. This is one reason financing conditions should be structured carefully, especially in competitive markets.

Appraisals are grounded in market evidence, not emotion. That means the appraised value is not based on how much a seller wants to net, how badly a buyer wants the home, or how much money was spent on renovations dollar for dollar.

A finished basement, new windows, or a renovated bathroom can absolutely help value, but improvements do not always return their full cost in an appraisal. The market decides what buyers are willing to pay for those features, and the appraiser reflects that market behaviour.

This is also why appraised value and purchase price are often close, but not always identical. In a fast-moving market, buyers may offer more than recent comparable sales support. In a slower market, a property may be priced high but appraised lower because the evidence is not there.

What if the appraisal comes in low?

This is the scenario people worry about most, and for good reason. If a home appraises below the agreed purchase price, the lender may reduce the amount it is willing to finance. That can create a shortfall that the buyer needs to cover out of pocket.

For example, if a buyer agrees to pay $800,000 but the home appraises at $775,000, the lender may base financing on the lower number. Depending on the mortgage structure, the buyer may need additional cash to close, renegotiate the price, or, in some cases, walk away if there is a financing condition in place.

A low appraisal does not automatically kill a deal, but it changes the conversation. Sometimes the parties renegotiate. Sometimes the buyer increases the down payment. 

Sometimes a second review is requested if there is strong evidence that the appraiser missed relevant comparable sales. It depends on the strength of the contract, the lender's flexibility, and how motivated each side is to keep the deal together.

Can sellers prepare for an appraisal?

Yes, but the goal is preparation, not staging for emotion alone. Sellers can make the appraiser's job easier by ensuring the property is accessible, tidy, and well-maintained. 

A home that shows clear pride of ownership tends to be easier to assess accurately.

It also helps to provide a list of meaningful upgrades, including dates if possible. New roofing, electrical updates, plumbing work, a renovated kitchen, or a legal basement

An apartment can be relevant. The appraiser may not give dollar-for-dollar credit, but accurate information matters. What sellers cannot do is force a number. The appraiser still has to support the value through data.

Why appraisals matter even in strong markets

When prices are rising quickly, people sometimes assume appraisals are just a formality. They are not. Lenders become more cautious when market conditions are volatile because they want confidence that the value is sustainable, not just optimistic.

In balanced or declining markets, appraisals can become even more influential because recent comparable sales may reflect softening demand. In both cases, an appraisal acts as a reality check.

This is one reason working with a knowledgeable local real estate professional matters. Pricing strategy, offer structure, and financing terms all interact with appraisal risk. At Fanis Makrigiannis Real Estate, that kind of planning is part of helping clients move forward with clarity instead of surprises.

A home appraisal is not there to complicate the process. It is there to establish value through evidence. Sometimes that supports the deal exactly as expected, and sometimes it exposes a gap that needs to be addressed.

If you understand that early, you can make smarter decisions about pricing, offers, financing, and timing. And when questions come up, the right guidance can make the entire process feel much more manageable.
