Underwater Condo? Sell, Rent or Hold: The Math Nobody Shows You

Quick answer: If your condo is worth less than you owe, you can’t simply sell and walk away. In Ontario, you must pay the shortfall in cash at closing, and if a lender later sells the unit under power of sale, it can still sue you for any amount left owing. The right choice depends on three numbers: how much cash you would need to sell today, how much you lose each month by holding, and how long you can carry that loss. Work those out before deciding, and talk to your lender early, because being underwater can also limit who will renew your mortgage.

Key takeaways

  • Toronto condo prices have fallen for several years in a row, and some forecasts expect further declines in 2026 and 2027.
  • If you owe more than 80% of the unit’s value on a regular mortgage, other lenders may refuse to take you at renewal. Plan for negotiating with your current lender.
  • A loss on a rental condo can usually reduce taxes on other capital gains. A loss on your own home cannot.

Step 1: Work out your real position

Number Where to find it Example
Realistic sale price Recent sales of similar units in your building (ask me for a free report) $560,000
Selling costs Commission, legal fees, any mortgage penalty $32,000
Mortgage balance Your latest statement $620,000
Cash needed to sell Balance + costs − price $92,000

If that last number is zero or less, you can sell without bringing cash. If it is large, keep reading.

Step 2: Compare your three options

Option Upfront cash Monthly cost Main risk
Sell now The shortfall (example: $92,000) None after closing Locking in the loss
Rent it out Small (leasing fee, any repairs) Mortgage + fees + tax + insurance − rent Vacancy, bad tenant, prices fall further
Hold and live in it None Your full carrying costs Renewal at a higher rate

Worked example (rent it out):

Monthly Amount
Mortgage payment $3,050
Condo fees $620
Property tax $230
Insurance and repairs allowance $120
Total cost $4,020
Rent you can realistically get $2,500
Monthly loss before tax $1,520

Over three years, that is about $55,000 out of pocket, plus whatever happens to the price. Compare that with the $92,000 to sell now. If prices recover even modestly over three years, holding may win. If they keep falling, selling sooner may cost less.

The honest test: could you carry the monthly loss for three years even if you lost your job for six months? If not, holding is riskier than it looks.

The renewal trap most owners don’t see coming

At renewal, a new lender will usually only take a regular mortgage up to 80% of the property’s value. If your unit is underwater, you are well above that, so switching lenders is usually not possible. Your current lender knows this.

What to do:

  • Start talking to your lender four to six months before renewal.
  • Ask for their best rate in writing, not the posted rate.
  • Ask about extending the amortization to lower the payment.
  • If you are struggling, ask about hardship options before you miss a payment.

Tax basics (check with an accountant)

Situation What you can usually deduct
Rented condo Mortgage interest, condo fees, property tax, insurance, repairs, against the rent. A rental loss can reduce your other income.
Selling a rental at a loss Half of the capital loss can offset capital gains (in the same year, three years back or any future year).
Selling your own home at a loss No deduction.

Options if you truly can’t carry it

  1. Sell and borrow the shortfall. Some lenders will convert the shortfall into an unsecured loan so you can close. It is not common, but it is worth asking.
  2. Find a buyer through an assignment-style deal (for units that have not closed yet; see our guide on pre-construction appraisal gaps).
  3. Sell before you fall behind. A normal sale almost always brings a better price than a power of sale, and it protects your credit.

Mistakes to avoid

  • Waiting until you have missed payments. Your options shrink fast.
  • Pricing above recent sales “to see what happens.” Stale listings sell for less.
  • Renting without a proper lease and screening. A bad tenant can turn a manageable loss into a disaster.
  • Ignoring condo fee increases and special assessments when you do the math.

FAQ

Can I just hand the keys to the bank?
No. Ontario lenders can sue for any shortfall after a power of sale, and it damages your credit badly.

Will renting it out cover my costs?
In many Toronto buildings today, rent covers only part of the costs. Run the numbers with realistic rent, not last year’s.

Should I wait for prices to recover?
Only if you can comfortably carry the monthly loss for several years. Nobody can promise when prices will recover.
