How to Buy and Sell a Home at the Same Time on the South Shore. Part Two of Two.

Part Two of Two: The Parallel Track, Explained

In Part One, I told you about a mom who walked into an open house and fell in love with a house she wasn't planning to buy. Not because she couldn't afford it and not because she didn't want to move. Because she didn't know how to buy her next home while selling her current one at the same time.

If that sounds familiar, you're not alone.

One of the most common questions I hear from homeowners in Hingham, Cohasset, Scituate, Norwell, Marshfield, Duxbury, and across the South Shore is: "Can I buy a house before I sell mine?"

The answer is yes. In fact, most move up buyers use one of three strategies:

1. Sell first, then buy (or run a parallel track through the transaction)
2. Make an offer contingent on selling their current home
3. Use bridge financing

The right choice depends on your finances, your timeline, and your comfort with risk. Let's break down each option. 

Can You Buy a House Before Selling Your Current Home?

Yes. Many homeowners assume they have to sell first because they can't imagine carrying two homes at once. The reality is that buying and selling simultaneously is less about luck and more about planning.

Whether you're moving from a starter home in Hingham, upsizing in Cohasset, relocating within Scituate, or looking for more space elsewhere on the South Shore, there are established ways to coordinate both transactions. The key is understanding which strategy fits your situation.

Should You Sell Your Home Before Buying Another One?

Option 1: List First, Then Buy

Best for: Homeowners who want the greatest financial certainty before making a purchase. This is often the most conservative and straightforward approach. You prepare your current home for sale, list it, and then begin shopping seriously for your next home.

Many sellers negotiate a closing timeline of 60 to 75 days, creating a window to identify, negotiate, and secure their next property before closing on their current home. You can also try to negotiate a contingency that gives you a certain number of days to find a suitable new home. You have options. 

Advantages

• You know exactly how much equity you'll have available
• You eliminate uncertainty around your home's sale price
• You reduce financial risk
• You avoid carrying two homes unexpectedly

Challenges

• Your home search timeline becomes compressed
• You may need to act quickly when the right property appears
• Inventory constraints can create pressure in competitive markets

What I Tell Clients

Start watching the market before you list. I will provide all the data to make smarter decisions and help alleviate some stress. The buyers who struggle most are often learning their target market while simultaneously trying to make a decision. The buyers who succeed know exactly what they're looking for before their home hits the market.

What Is a Home Sale Contingency and How Does It Work? (or not work in some cases)

Option 2: Make an Offer Contingent on Selling Your Home

Best for: Buyers who find the right home before selling their current one.

A sale contingency means your offer is dependent upon the successful sale of your existing home. If your home doesn't sell within the agreed upon timeframe, you can typically withdraw from the purchase without losing your deposit. For many buyers, this feels like the safest option because it protects them from owning two homes at once. BUT... the market in the South Shore at the time I'm writing this still favors sellers. There may be strong pushback to a home sale contingency from the seller. It's not impossible but needs to be written properly for consideration and there are some properties that it may work better for like homes that have seen 21+ days on market without an offer or have taken price reductions already. 

Advantages

• Limits financial exposure
• Creates a built in safety net
• Allows you to pursue a home before your current property is sold

Challenges

• Sellers generally prefer non contingent offers
• Your offer will be less competitive in multiple offer situations
• You may need to strengthen other terms of your offer

When It Works Best

Sale contingencies often work when:

• The home has been on the market longer
• The seller has flexibility
• Your current home is highly marketable
• Your price point has less competition

A contingent offer isn't automatically weak. It simply needs to make sense within the context of the transaction.

What Is Bridge Financing and When Does It Make Sense?

Option 3: Use Bridge Financing

Best for: Buyers who want to purchase before selling.

Bridge financing allows homeowners to access the equity in their current home before that home is sold. The bridge loan provides funds that can be used toward the down payment on the next property. Once the current home sells, the bridge loan is paid off. For many move up buyers, this creates flexibility that would otherwise be impossible.

Advantages

• You can buy before selling
• You move only once
• Your offer can compete more effectively against non contingent buyers
• You gain flexibility on timing

Challenges

• Higher borrowing costs than traditional mortgages
• Temporary carrying costs on both properties
• Qualification requirements vary by lender

Who Typically Qualifies?

While every lender is different, most bridge financing programs look for:

• Significant equity in the current home
• Stable income
• Strong credit
• Adequate reserves

Many South Shore homeowners who purchased between 2018 and 2020 have accumulated meaningful equity, making bridge financing worth exploring.

How Do You Buy and Sell a House at the Same Time?

Regardless of which strategy you choose, the preparation process is remarkably similar. I encourage clients to think about three parallel tracks.

Track One: Understand Your Current Home's Value

Before anything else, know what you have. That means:

• Obtaining a professional market valuation
• Understanding current market conditions
• Reviewing your mortgage balance
• Estimating net proceeds after closing costs and commissions

Online estimates can be a starting point, but they shouldn't be the foundation of a major financial decision.

Track Two: Understand Your Purchasing Power

Before falling in love with the next home, understand what you can realistically buy. That includes:

• Mortgage pre approval
• Asset review
• Equity analysis
• Bridge financing conversations if appropriate

The goal is clarity.

Track Three: Stay Ready

The best opportunities often appear before people feel fully prepared. That's why I encourage buyers to:

• Define their non negotiables
• Monitor inventory consistently
• Tour homes when appropriate
• Understand local pricing trends

Preparation creates confidence and confidence creates speed when the right home appears.

The biggest mistake move-up buyers make is waiting for certainty.

They want every question answered before taking the first step. They want the market to settle. They want rates to improve. They want inventory to increase. They want perfect timing. The problem is that perfect timing rarely announces itself. The families who move successfully aren't necessarily the ones who have everything figured out. They're the ones who start gathering information before they need it. Because when the right house appears, preparation matters far more than prediction.

Frequently Asked Questions About Buying and Selling a Home at the Same Time

Can I buy a house before selling my current home?

Yes. Many buyers accomplish this through bridge financing, sale contingencies, or careful coordination of closing timelines.

Should I sell first or buy first?

There is no universal answer. The right strategy depends on your finances, market conditions, risk tolerance, and available inventory.

What is a bridge loan?

A bridge loan is a short term financing solution that allows homeowners to access equity in their current home before it sells.

How much equity do I need to buy another home?

The amount varies depending on financing, down payment requirements, and lender guidelines. A lender can help determine what's possible based on your specific situation.

How long does it take to buy and sell simultaneously?

Most coordinated transactions take several weeks to a few months depending on inventory, financing, and market conditions.

The First Step Isn't What Most People Think

The mom from Part One didn't need a perfect plan. She didn't need a mortgage application, she needed clarity. That's usually where this process begins. If you're wondering whether your equity is enough, whether bridge financing could work, or whether now is the right time to make a move, start there. Not with pressure but with information. One of my favorite writers, Brene Brown, says, "clear is kind, unclear is unkind." and the same thought applies here. 

Because buying and selling at the same time isn't a gamble, it's a process that is successful when you have clarity and a plan.  And every successful move starts with understanding your options.
