Sell First or Buy First?
Sell Before You Buy
or Buy Before
You Sell? It Depends.
This is the question I get asked more than almost any other. And the honest answer is that there is no universal right answer — it depends on your financial position, the current market conditions, your risk tolerance and what is actually available to buy. What this post covers is how to think through the decision, what the real risks are on each side and the two tools most people don't know exist that can make the timing work.
The Core Tension — Why This Decision Is Hard
Selling and buying simultaneously is one of the most logistically complex things most people will ever do in their financial lives. The difficulty comes from a fundamental timing problem: your sale and your purchase are two separate transactions that each have their own timelines, their own conditions and their own closing dates — and getting them to align cleanly is harder than it sounds.
On one side, you want to know what your home sold for before you commit to buying something else. On the other side, you don't want to sell your home and then have nowhere to go. Both instincts are reasonable. The tension between them is real and it doesn't fully resolve — you manage it rather than eliminate it.
“There is no sequence that removes all the risk. Every approach involves a trade-off. The goal is to understand each trade-off clearly so you can choose the one you can live with.”
Selling First — The Case For and Against
Selling first means you know exactly what you have to work with before you commit to a purchase. Your budget is real, not estimated. Your financing is straightforward because there is no existing mortgage to work around. And you are not carrying two properties if the timing gets messy.
The deadline pressure risk is the one I see cause the most problems. A seller who has a firm closing date in 60 days and hasn't found the right home yet is a buyer in a compromised position — and motivated buyers in a time crunch often end up paying too much or settling for a home that doesn't actually fit them. If you sell first, give yourself as long a closing window as the buyer will accept to reduce this pressure.
Buying First — The Case For and Against
Buying first means you secure the home you want before you lose it to another buyer. In a competitive market where the right property doesn't come up often — a specific neighbourhood, a specific property type, a specific price point — this approach makes sense. You are not making a rushed decision on the purchase side.
Buying first works best when you have the financial capacity to carry two properties for a short period if needed, and when you have high confidence in what your home will sell for and how quickly. Before going this route, talk to your mortgage broker about whether you can qualify for both mortgages simultaneously — not everyone can, and finding out after you've bought is the wrong time to discover it.
Bridge Financing — The Tool Most People Don't Know About
Bridge financing is one of the most useful tools available to buyers in a simultaneous sale and purchase situation — and one of the least understood. Most people have never heard of it until they need it.
Bridge financing is a short-term loan that allows you to use the equity in your existing home to fund the down payment on your new home — before your existing home has actually closed. It bridges the gap between your purchase closing date and your sale closing date when those two dates don't align perfectly.
Example: You buy a new home closing October 15. Your existing home sells and closes October 30. You need your down payment available on October 15 but your sale proceeds don't arrive until October 30. A bridge loan covers that 15-day gap. When your sale closes, the proceeds pay off the bridge loan and the rest flows to you as equity.
Bridge financing typically requires that you have a firm, unconditional sale in place on your existing home — most lenders won't bridge an unsold property. The interest rate is higher than a standard mortgage rate, but the term is short (days to a few weeks typically) so the total cost is usually modest. Always confirm bridge financing availability with your mortgage broker before you need it — not every lender offers it and the terms vary.
Bridge financing essentially buys you a short timing gap without having to carry two full mortgages. If your sale is firm and your closings are within a few weeks of each other, it is often the cleanest solution to the timing problem.
The SBP Condition — The Other Tool Worth Understanding
The Sale of Buyer's Property (SBP) condition is a clause that can be included in a purchase offer that makes your obligation to complete the purchase conditional on selling your existing home first. It is a legitimate and regularly used tool — and one that most buyers don't think to ask about.
When you include an SBP condition in your offer, you are saying: "I will buy this home, provided I sell my current home within a defined period." The seller agrees to this, typically with an escape clause (also called a bump clause) attached.
The escape clause allows the seller to continue marketing their home and accept other offers. If a second buyer comes along with a firm offer, the original buyer — you — is typically given 24 to 72 hours to either remove the SBP condition and proceed firm, or walk away and allow the seller to accept the new offer.
What this means for buyers: An SBP condition protects you from being locked into a purchase if your home doesn't sell. It is particularly useful in a slower market where you need more time to sell.
What this means for sellers: A home listed with an accepted SBP offer is not off the market. Keep showing it. The bump clause exists precisely for this scenario.
The SBP condition is underused in Waterloo Region because buyers assume sellers won't accept it. In the current market — where months supply is in the 2.8 to 3.4 range for single family homes — some sellers will accept an SBP if the price is right and their timeline allows for it. It is always worth discussing with your agent before ruling it out. Read the full Seller FAQ for more on conditions and how offers work →
When I sit down with clients on this, I bring it back to three questions. Are we in a buyer's market or a seller's market right now? Is your home an easy sell or is it going to take some time? And is what you're looking for rare and hard to find, or are there a handful of options you'd be happy with available at any given time? The answers to those three questions will tell you most of what you need to know.
The reality is, you're always going to get a better deal if you're effectively a cash buyer — meaning you don't need your home sold in order to purchase. You have no conditions, no pressure, no deadline hanging over the negotiation. That's a genuinely powerful position to be in. But it's easier said than done. Bridge financing can help get you there. Selling first and negotiating a long closing can help too.
Every situation is unique. You need to go through the specifics with an experienced agent, be realistic about what your options actually are and make the decision that fits your circumstances — not the one that sounds best in theory.
How to Decide — The Questions That Matter
The right sequence depends on your specific situation. Here are the questions that actually determine the answer:
What This Looks Like in Practice
You own a 3-bedroom detached in Cambridge that will sell quickly and at a predictable price. Your criteria for the next home are clear but flexible — a few different neighbourhoods would work, a few different layouts. You don't have the financial buffer to carry two mortgages comfortably. In this case, sell first, negotiate the longest closing date you can get, and use that window to find and buy your next home. If you find it before your sale closes, bridge financing covers the gap. If you haven't found it by closing, rent short-term while you look without pressure.
You have been searching for a specific type of home in West Galt for eight months. One just came on the market and it is exactly what you want. You have the financial capacity to carry both mortgages for a few months and your existing home is well-positioned to sell. In this case, buy first — conditional on financing if possible — and list your existing home immediately. The cost of missing the right home outweighs the carrying cost risk.
You have found a home that works but the seller's timeline is flexible and the market is balanced. You make an offer with an SBP condition, the seller accepts with a 60-day bump clause. You list your home immediately. If your home sells firm within 60 days — which in a normal Cambridge market is likely — you waive the SBP and proceed. If the seller gets another offer first, you have 48 hours to decide whether to firm up or walk away.
