My parents want to sell me their $380K home for $200K — but on a $3,100 monthly income, is the built-in equity worth the risk?

His parents are preparing to retire and downsize to a smaller home. They’ve offered to sell him their home — which is worth $380,000 — for $200,000. This opportunity gives Daniel a rare foothold in the housing market and $180,000 in built-in equity. Still, even at a steep discount, the purchase could leave him house-poor once he takes on a mortgage and accounts for additional expenses like utilities, insurance, property taxes and maintenance.

Selling a family home to an adult child below market value isn’t unusual, and in Canada, there’s no federal gift tax imposed on doing so. But the decision still has real financial implications. Daniel would need to decide whether the equity outweighs the strain of carrying a home on a modest income — and his parents would need to ensure the sale fits into their retirement plans.

The financial implications of buying below fair market value

Unlike the U.S., Canada doesn’t impose a gift tax, so selling a home to a family member for below fair market value (FMV) is generally permitted.

In Daniel’s case, his parents would avoid paying capital gains tax on the sale of their home, as they can shelter any appreciation they’ve earned using the principal residence exemption (1).

But just because the Canada Revenue Agency (CRA), Daniel and his parents are all accepting of the sale, doesn’t mean there aren’t potential tax implications.

Because Daniel is paying less than the home’s FMV, the CRA would not recognize the FMV as Daniel’s initial purchase price. Instead, they’d use the actual price he paid — which is $200,000. At first, this won’t have any tax implications for Daniel (or his parents). The base cost is simply used to establish Daniel’s adjusted cost base (ACB) — the amount he paid for the asset, according to the CRA.

A variety of factors can impact ACB — such as upgrades — but the real importance of establishing ACB is that it determines what a person paid for an asset. When the asset is sold (or the use is deemed to have changed, for tax purposes), the sale price is then compared to the ACB. The difference between these two numbers is what the CRA will use to calculate tax owed (2).

Initially, the ACB — and the difference between the home’s FMV and what Daniel paid — won’t matter; however, should Daniel choose to rent out a room, or, in the future, move out and turn the home into a rental property, that initial base price will play a factor (3). Why? Because only property used as primary shelter — a principal residence — can be used to shelter you from paying capital gains tax. All other property, including cottages, vacation homes, recreational land, and investment properties will trigger tax owed when sold (or the use is changed).

The same situation arises if a parent chooses to gift a property. While the adult child may not pay anything out-of-pocket, the CRA will still consider it a sale at fair market value.

To illustrate, consider the following breakdown:

Tax implications for the seller

Remember, capital gains are based on FMV — not the sale price — but only paid if the home was not the seller’s principal residence (aka: primary home).

So, if the home is not the seller’s principal residence, the seller must calculate capital gains as if they sold at FMV. Example:

• FMV of home: $380,000
• Sold to child for: $200,000
• Original purchase price: $100,000

CRA treats this as:

• Deemed sale price: $380,000
• Capital gain: $280,000

Notice, that the seller pays tax as though they received full market value for the property.

Tax implications for the buyer

Even though the buyer’s adjusted cost base is lower, the price used for tax purposes is the fair market value price. Example;

• Buyer pays $200,000
• FMV at time of sale: $380,000
• Buyer later sells for $600,000

The capital gain is calculated on:

• $600,000 – $200,000 = $400,000
  Not:
• $600,000 – $380,000 = $220,000

Now, if the buyer never rented the property out and simply used the property as their principal residence, then no capital gains tax is owed. But any income earned on the property — and any change of use — could trigger a “sale” according to the CRA and the ability to avoid paying capital gains tax disappears.

Beyond tax, what about affordability?

Beyond tax considerations, the bigger question is affordability. Even with built-in equity, Daniel still needs to qualify for a mortgage, cover closing costs and ongoing housing expenses such as utilities, insurance, maintenance and property tax — costs that are easy to underestimate after just starting out living in a shared housing scenario.

Since about 47% of the home’s value is essentially gifted, Daniel may not need to provide a large cash down payment. However, his lender will require a formal appraisal to confirm FMV and will ask his parents to sign a gift letter confirming the equity transfer isn’t a loan (4).

Depending on the outcome of the appraisal, Daniel may choose to keep at least a portion of his $40,000 savings to build an emergency fund rather than putting it all toward the purchase price.

Finally, Daniel’s parents should consider whether selling the home for less than its FMV aligns with their long-term financial plans. If the proceeds from selling the home count toward their retirement, a below-market sale also reduces their buffer unless they already know how it factors into their plans.

It’s a great opportunity, but is it affordable?

Even with built-in equity, affordability is the main concern for Daniel. If he finances the purchase, the mortgage amount would typically be based on the purchase price ($200,000) minus any cash down payment, though some lenders may treat the discount (gift of equity) as down payment depending on their policies.

As of January 2026, advertised 5-year fixed rates varied by lender and borrower profile; some comparison sites showed lows around the high-3% range and averages around ~4%. (5).

At that rate range, monthly mortgage payments on a $200,000 loan over a mortgage amortized over 25 years would look something like this:

• At 3.74%, the monthly payment would be just under $1,030
• At 4.09%, the payment would be just over $1,065

These numbers are a sizable monthly commitment for someone earning about $3,100 after deductions. Plus, the lower estimate is higher than 30% of Daniel’s take-home pay, which goes against the recommendation to keep housing costs between 25% and 30% of your net income (6).

Plus, Daniel will need to put a down payment on the home — with a minimum down payment of at least 5% of the home’s FMV. That’s because Canadian lenders require 5% on the first $500,000 and 10% on the portion above that amount (7). If the lender treats the $180,000 discount as a gift of equity (eligible down payment), Daniel’s effective equity could exceed 20%, which would generally avoid mortgage default insurance; otherwise, insurance could still apply depending on how the loan is structured.

Beyond principle and interest, Daniel will still need to budget for other ongoing costs that add to his monthly mortgage payment:

• Property taxes and home insurance. These vary by municipality and are a regular cost for homeowners.
• Utilities and maintenance. A practical rule of thumb is to budget 1% of the home’s value per year for upkeep. If the house is appraised at $380K, Daniel can expect to pay $3,800 annually.
• Closing costs. Legal fees, land transfer tax (which ranges about 0.5% to 4% of the purchase price, depending on the province and purchase price), title insurance and inspection costs can add between $4,000 to $12,000 at closing (8).

National housing affordability data show that even before other costs, monthly ownership expenses for typical homes often consume a large share of income (9). Many households in major Canadian cities spend far more than the guideline threshold — where mortgage payments plus taxes and utilities are ideally kept below about 32% to 39% of gross monthly income.

Daniel’s own net monthly income of about $3,100 (roughly $37,000 annually) places real pressure on this kind of ownership. If his total housing costs exceed half of his monthly income, he could quickly find himself house-poor, with limited budget left for savings, long-term goals or emergencies.
