Upsizing in Ottawa: from a condo or townhouse to more space

The short answer: upsizing works best when you decide what "more space" actually has to do for you, then check three numbers before you shop: the equity you'll really have after selling, the cash the purchase needs on and before closing, and the full monthly cost of the bigger home. The gap between the two prices is not the cash you need.

This guide is about the decision and the numbers. For dates and the order of the two closings, read the Selling & Buying guide.

Who this is for

You own a condo apartment, condo townhouse or freehold townhouse in the Ottawa area and you're starting to feel short on room: a growing family, working from home, a parent moving in, or simply wanting a yard or a garage.

The decision usually isn't "should we move?" It's "what are we trading to get the space, and can we carry it comfortably?" Sometimes the honest answer is to stay put, renovate or wait. That's a fine outcome too.

What "more space" really means

Before looking at listings, write down what the extra space is for. A home office, a third bedroom, a finished basement and a yard solve different problems, and they come with different houses.

Then decide what you're willing to trade. Compare individual properties rather than assuming what an area offers:

Same area, different home. Check how the address affects your commute, school eligibility and routines. Look at what's actually available on the streets you want.
A different part of the city. Compare the specific homes available, and test the commute at the hours you'd actually drive or take transit.
Villages and nearby towns. Some properties have a well, a septic system, different services or longer winter driving. Check each one for the specific property.
The same square footage, used better. A home with a better layout, a usable basement or a main-floor office can feel bigger than a larger home that doesn't fit how you live.

Compare areas by fit, not by a ranking. The Ottawa communities guide is a good place to start. If schools matter, check eligibility by exact address with the school board; living near a school doesn't guarantee a place in it.

The price gap is not the cash you need

Here's a hypothetical illustration. These are made-up round numbers to show the arithmetic, not Ottawa prices or a forecast.

Sale price of your current townhouse: $600,000
Purchase price of the larger home: $850,000
Price gap: $250,000

That $250,000 is the difference between the two prices. It is not the cash you need. The cash you need depends on:

Your available equity. In this example, if the mortgage balance were $350,000, you'd have $250,000 before selling costs. From that, subtract the remaining selling costs, payouts and net adjustments: any prepayment penalty and discharge fee, other secured-debt payouts, commission and applicable tax, legal fees and closing adjustments. Moving and preparation costs you pay before closing come out of your savings, not again from the proceeds.
The deposit. Confirm the deposit amount and deadline in your agreement before signing. Arrange accessible funds without assuming your sale will close first. The deposit is credited toward your down payment at completion; don't count it twice.
The down payment and closing costs. The Financial Consumer Agency of Canada says to be prepared to spend between 1.5% and 4% of the purchase price on upfront or closing costs, on top of the down payment, such as legal fees, home inspection, title insurance and property tax adjustments. Your actual costs can differ, so get itemized quotes from your lender and lawyer and keep a reserve for contingencies.
Mortgage qualification. The new mortgage has to be approved on your income and debts. Equity helps, but it doesn't replace qualifying.

Ontario's land transfer tax refund for first-time buyers usually won't apply here. If you have previously owned a home or an interest in one anywhere in the world, you do not qualify for Ontario's first-time homebuyer land transfer tax refund. Separate spouse-ownership rules also apply. If you're buying with someone else, your lawyer can confirm how any co-purchaser's eligible share is treated and the land transfer tax payable on your purchase.

How your monthly costs change

A bigger home changes more than the mortgage payment. Compare the full monthly picture side by side, using your actual bills and quotes.

Mortgage: the payment at the new amount and rate, from your lender. Ask whether porting is available and how it affects penalties and fees.
Property tax: the actual tax information for the home you're considering, not an estimate from a different street. Taxes can change, so the current bill isn't a guarantee of future costs.
Utilities: heat, hydro and water for a larger space. Ask the seller for past bills where possible.
Insurance: get a new quote for the home you're considering; coverage needs can differ between a condo unit and a freehold home.
Maintenance (if moving from a condominium to a freehold home): items such as the roof, windows, furnace, driveway, lawn and snow may become yours. Set money aside every month.
Condo fee you stop paying (if moving from a condominium to a freehold home): list what your fee covered under your condo's documents and price replacing each item.

FCAC notes that CMHC says monthly housing costs (mortgage, property tax and heat) should be no more than about 39% of gross monthly income. That's a general guideline, not a personal affordability assessment or mortgage approval.

Sell first, buy first, or coordinate the two

Each order has a different risk. The Selling & Buying guide walks through dates and examples, and Should you buy first or sell first in Ottawa? covers the trade-offs. In short:

Sell first: a firm sale gives you a clearer estimate of proceeds, but you may need flexible possession or temporary housing.
Buy first: you secure the home, but you risk carrying two properties if your sale takes longer or sells for less.
Coordinated closings: both deals close on the same day or close together. This is tidy, but it leaves little room if one side is delayed.

Fallback options to discuss before you commit:

A condition on the sale of your home. A properly drafted condition may provide an exit on specified terms; have your lawyer review its deadlines and requirements. Sellers may find a conditional offer less attractive.
Bridge financing. RBC describes it as a temporary loan that lets you use your current home's equity before the sale closes, and says RBC requires a firm sale agreement on your existing home to qualify. It can cost more than regular mortgage interest. Other lenders set their own terms, so ask yours.
Flexible closing dates. Negotiate them on either or both deals.

Questions for your lender

What purchase price and monthly payment am I approved for, and on what assumptions?
Is porting available, and how does it affect penalties and fees? If I don't port, what would the prepayment penalty and discharge fee be? (FCAC explains how prepayment penalties work and what porting means.)
Do I qualify for bridge financing, and what are the rate, fees and maximum term?
Can I carry both mortgages if my sale is delayed? For how long?
Where can the deposit come from, and what documents will you need?

Questions for your lawyer

What deposit am I committing to, and when is it due under the agreement?
What will the land transfer tax and my closing costs be on this purchase?
How will the money flow on closing day if both deals close together?
What happens if one closing is delayed, and what do the condition and closing clauses actually require of each side?
Is there anything on title, a survey or the property (such as a well, septic system or easement) I should understand first?

Talk it through

If you're not sure whether to move yet, that's a good time to talk. Staying put is a fine answer too.
