Buy First or Sell First? How to Decide When Moving Homes

The ideal move closes the sale of your old home and the purchase of your new one on the same day, with the money flowing seamlessly. In reality, the two closing dates rarely line up — which makes the order a real decision: sell first and you may be temporarily without a home; buy first and you may temporarily carry two mortgages.

I’ve watched too many people decide on instinct and end up either dumping their old home below value or losing sleep under two monthly payments. This piece lays out the framework so your decision rests on the market and your cash flow — not on luck.

Sell first: certain cash flow, but you may have to camp out

Sell your old home first (with an unconditional offer in hand) and you know exactly how much you have and how much new home you can afford. It completely eliminates the risk of carrying two mortgages. In a buyer’s market where homes are slow to sell, this is the steadier choice.

The trade-off: if your old home closes before you’ve found or closed on a new one, you may need to rent short-term, move twice, or put furniture in storage. In other words, you trade a bit of lifestyle inconvenience for financial certainty. For tight budgets that can’t absorb two payments, that trade usually pays off.

Buy first: live with ease, if you can carry both costs

Lock in the home you love, then sell your old one without pressure. This is the most comfortable living experience — no camping out. In a seller’s market where homes sell fast at strong prices, the risk of this order is manageable.

But it assumes you can withstand the scenario where your old home doesn’t sell on time — meaning you might briefly carry two mortgages plus property tax, fees, and insurance on both. Buying first essentially trades carrying costs and market risk for living convenience. When the market cools, that bet gets expensive.

Bridge financing: a tool to span closings, not a safety net

When your new home closes before your old one sells (typically within 90 days, which varies by bank), bridge financing steps in. According to major Canadian banks (2025), it uses the equity in your old home to temporarily fund the down payment on the new one, then is repaid in full from the sale proceeds once your old home closes.

The key condition: most banks require you to already have a firm, unconditional sale agreement before they’ll advance a bridge loan — because the repayment source is that confirmed sale. On cost, the rate is typically prime + 2% to 3%, plus an administrative fee of roughly $200 to $500. It solves a date gap, not an unsold home.

This is the most dangerous misconception. A bridge loan assumes you’ve already sold — the money just hasn’t arrived. If your old home has no unconditional offer, banks generally won’t approve a bridge loan, and you’d have to cover the gap between closings yourself with cash or a line of credit. So before buying first, confirm with your mortgage broker: if your old home sells 60 to 90 days late, can your cash flow survive it? If not, don’t take the bet.

Insure yourself with market reads and contract clauses

Beyond choosing the order, two tools reduce risk. First, a purchase offer conditional on the sale of your existing home: you make buying the new home contingent on selling your old one, shifting the risk away from you — but in a seller’s market, sellers rarely accept such offers, so it fits buyer’s markets best.

Second, align closing dates and deposits: negotiate the buy and sell closings to land on the same day or close together, shrinking the bridge window to a minimum; and confirm where your new-home deposit comes from so it doesn’t collide with the equity tied up in your old home. According to TRREB (2025) data, Toronto is in a buyer’s market when the sales-to-new-listings ratio (SNLR) falls below 40% — confirm which side your segment leans toward before choosing the order.

Q: Should I really buy first or sell first?

It depends on the market. In a buyer’s market (homes are slow to sell, buyers hold leverage), selling first is safer and fully avoids carrying two mortgages. In a seller’s market (homes sell fast), buying first is a manageable risk and far more comfortable to live through. Read which way your price point and neighbourhood lean before choosing.

Q: How does bridge financing work?

When your new home closes before your old one (usually within 90 days, varying by bank), a bridge loan uses your old home’s equity to temporarily fund the new down payment, then is repaid from the sale proceeds once the old home closes. According to major Canadian banks (2025), the rate is typically prime + 2% to 3%, plus a roughly $200 to $500 admin fee. Most banks require a firm, unconditional sale first.

Q: If my old home won't sell, can bridge financing save me?

No. A bridge loan assumes you already have a firm sale — the funds just haven’t landed. If your old home hasn’t sold and has no committed buyer, banks generally won’t approve a bridge loan, and you’d carry both mortgages on cash or a line of credit. This is the biggest risk of buying first — run the numbers with your mortgage broker before you commit.

Q: What is a conditional-on-sale offer, and how does it help me?

It’s a condition you attach when buying a new home: the deal only closes if your existing home sells. It shifts the ‘can’t sell my old home’ risk away from you, protecting buy-first movers. But in a seller’s market, sellers with multiple offers usually won’t accept it, so it’s best suited to buyer’s markets.

Q: What's the ideal closing arrangement when moving?

The ideal is closing your purchase and sale on the same day, so funds flow seamlessly — no temporary move, no bridge loan, no double mortgage. That’s hard to align perfectly, so the next best thing is negotiating the two closing dates as close together as possible, minimizing both the bridge window and the period of carrying two homes.
