If you already own a home in Greater Boston and you are moving to another one, the order of operations matters more than almost anything else in the move. Sell first and you protect your finances, but you may end up in temporary housing. Buy first and you protect your lifestyle, but you carry two properties until the first one sells. My general recommendation for 2026 is that for many Greater Boston owners, selling first or coordinating same-day closings reduces risk, unless they have strong liquid reserves that let them absorb an overlap comfortably.
That is a recommendation, not a rule, and it is not a coin flip either. Your answer comes down to four things you can actually measure: how much equity you have, how much cash you can access without touching that equity, how quickly your current home will sell at the right price, and how much competition you will face on the buy side. Once you know those four numbers, the order usually picks itself.
Who this applies to
This is the move-up buyer in Braintree who needs a fourth bedroom. The empty nester in Milton who wants to trade the colonial for a single-level condo. The family in Weymouth relocating to Hingham for the schools. The homeowner in Dedham whose parents are aging and who wants to be closer to them.
What all of these have in common is that the down payment for the next house is sitting inside the current house. If you have enough liquid cash to buy the next home outright, or to put down what you want without touching your equity, most of this decision goes away and you simply buy first. For everyone else, the equity has to move before it can be spent, and that timing question is the whole ballgame.
The four numbers that decide it
Before you weigh strategies, get honest answers to these.
Your usable equity. Not your Zillow estimate. Take a realistic sale price for your home, subtract your mortgage payoff, subtract selling costs, and see what is actually left. Sellers in most Massachusetts counties pay a deed excise tax of $4.56 per $1,000 of consideration, calculated at $2.28 per $500 or fraction of it, and paid at the registry when the deed is recorded. There are county exceptions, including Barnstable County and the Islands, which carry higher rates or additional land bank fees. On a $700,000 sale in most Massachusetts counties, the deed excise is about $3,192. Add commission, attorney fees, and the fire department inspection and certificate of compliance discussed below.
Your liquid cash outside the house. Savings, brokerage accounts you are willing to sell from, a 401(k) loan you are willing to take. This is what determines whether you can carry two mortgages for a stretch, and for how long.
Your realistic days on market. Ask your agent for the actual median days to offer for homes like yours, in your town, in your price band, right now. Not the regional average. A well-priced three-bedroom in Weymouth and a $1.6 million contemporary in Cohasset are completely different clocks.
Your buy-side competition. If the homes you want are getting multiple offers within a week, a sale contingency will be far less competitive than a clean offer. If they are sitting for a month, a contingency is negotiable. That single fact moves the recommendation more than anything else.
What the 2026 market is actually doing
Two things are worth knowing before you pick a strategy, and both should be read as trends rather than fixed numbers.
Mortgage rates have been running in the mid-6% range recently, roughly in the low to high 6s depending on the week and the loan. That is high enough to keep some sellers in place, which is part of why inventory has stayed tight in the towns people most want to be in, and low enough that qualified buyers are still transacting.
Prices have held up, but the region is not one market. Single-family medians across Greater Boston have been running well above the seven-figure line in the strongest months, while condos sit meaningfully lower, and individual submarkets diverge sharply by town and price band. The inner core, the strong South Shore towns, and the higher price points are all behaving differently from each other right now. Any strategy built on a regional average will misfire in at least one direction, which is why the days-on-market number for your specific town and price band matters more than any headline.
The five real options
Most people think this is a two-way choice. It is closer to five.
| Strategy | How it works | Best for | The real risk |
|---|---|---|---|
| Sell first, then buy | Close on your sale, then buy with cash in hand | Owners whose equity is the down payment, tight budgets | You may need a rent-back or short-term housing, and you buy in whatever market exists at that moment |
| Same-day closings | Sale closes in the morning, purchase in the afternoon, proceeds wire straight over | Owners with enough flexibility to align two sets of parties | If one closing slips, the other can slip with it, so both attorneys need to be coordinating from day one |
| Buy first with a bridge loan | Short-term financing against your current home covers the timing gap and funds the new down payment | Strong equity, strong income, high buy-side competition | It is expensive short-term money, not a routine solution. You carry two payments plus the bridge, and rates run meaningfully higher than a first mortgage |
| Buy first with a HELOC | Draw a line of credit on your current home for the down payment | Owners who plan far enough ahead to open the line first | Most lenders will not open a HELOC on a home that is already listed, so this only works if you set it up in advance |
| Buy with a sale contingency | Your offer to purchase is conditioned on your home selling | Softer segments and price bands with less competition | In competitive Greater Boston submarkets, a contingent offer is far less competitive than a clean one, or you pay a premium to win |
What separates the people who do this well
They set the sale up before they shop. The owners who move smoothly have their current home photographed, prepped, and priced before they write an offer on anything. That way, when they find the house, they can go live in days instead of weeks. The gap between finding it and getting your own house on the market is where most of the stress lives.
They handle the smoke and carbon monoxide certificate early. In Massachusetts, smoke alarm compliance on the sale or transfer of a home is governed by M.G.L. c. 148, section 26F, and carbon monoxide alarm compliance by section 26F and one half. The local fire department inspects and issues the certificate of compliance, and closings generally will not proceed without it. Here is the trap: the certificate expires 60 days after issuance. Schedule it too early and it lapses before you close, schedule it too late and a failed inspection can push your date. When you are running a sale and a purchase in the same week, this small piece of paper causes more last-minute scrambling than it should.
They negotiate for time, not just for price. A use and occupancy agreement, sometimes called a rent-back, lets you close on your sale and stay in the home for a defined period afterward while you close on the purchase and move. Buyers will often agree to a short one, especially if it helps them win the house. It is negotiated in the transaction documents and should be reviewed with your attorney, because possession, insurance, liability, the daily rate, and holdover terms all matter. Note too that some loan programs and lenders impose occupancy timing requirements on the buyer, which can limit how long a rent-back they are able to offer.
They price to sell, not to test. If your plan depends on your home selling, an aspirational list price is not a harmless experiment. Every week you sit is a week of carrying costs, and in Greater Boston a stale listing invites lower offers than a fresh one at the right number.
They know their walk-away number before they shop. Decide in advance the maximum you will spend on the next home if the sale comes in at the low end of your range. Write it down. It is much easier to hold that line before you have fallen in love with a house.
They line up the attorney early. Massachusetts is an attorney closing state, and an attorney conducts the closing. When you are running a sale and a purchase in the same window, having one attorney coordinating both sides of your move is worth a great deal.
How to position, by situation
If you have strong equity and strong cash reserves, and the town you want is competitive, buy first. Use a bridge loan or a pre-opened HELOC, then sell your home vacant and staged, which almost always brings a better result than selling while you live in it. You are paying for certainty, so know what that certainty costs per month before you commit.
If your equity is the down payment, sell first and negotiate for a rent-back. This is the most common situation in Greater Boston and there is nothing second-class about it. You sell into a market where you control the timing, you know your exact number, and you shop as a non-contingent buyer, which is a real advantage when you finally write the offer.
If you are moving within the same market and the timing is workable, aim for same-day or back-to-back closings. It is the cleanest financial outcome. Using the same attorney for both transactions simplifies the coordination considerably. Just be realistic that it requires both sets of parties to hold their dates, and it needs a plan B if one slips.
If you are shopping in a slower segment, at a higher price point, or on a longer timeline, a sale contingency is worth trying. Sellers of homes that have been sitting are far more open to it than the listing agent's first response suggests.
A note on the tax side
If you have owned and lived in your home as your primary residence for at least two of the last five years, federal law lets you exclude up to $250,000 of gain from capital gains tax if you file singly, and up to $500,000 if you are married filing jointly. Massachusetts conforms to that federal exclusion, so gain that is excluded federally is generally not taxed at the state level either.
Where it gets more interesting is the gain above the exclusion. Massachusetts taxes long-term capital gains at 5%, and the state's 4% surtax applies to taxable income above an inflation-indexed threshold that sits in the neighborhood of $1.08 million for 2026. A large gain on a long-held Greater Boston home can push a household over that line in the year of the sale, even if their normal income is nowhere near it. If you have owned a long time in a town that has appreciated hard, run the numbers with your accountant before you assume the exclusion covers you. Sometimes the timing of the sale itself is worth planning around.
The bottom line
Buying first buys you convenience. Selling first buys you certainty. In the 2026 Greater Boston market, certainty is generally the better purchase unless you have the cash to make convenience genuinely comfortable rather than merely possible.
Start by getting a real number on your home, a real number on your usable equity, and a real read on how competitive your target towns are right now. Once you have those three things, the order stops being a debate and starts being arithmetic.
FAQ
Common questions, answered.
How long does it usually take to sell a home in Greater Boston right now?
It depends heavily on town and price band. Well-priced homes in the strong South Shore towns have been moving quickly, while higher price points and softer inner-core segments take longer. Ask for the median days to offer for your specific town and price range, since the regional average will mislead you in either direction.
Can I use a HELOC on my current home for the down payment on the next one?
Sometimes, but the timing is strict. Most lenders will not open or fund a home equity line on a property that is already listed for sale, and some will freeze an existing line once it lists. If a HELOC is part of your plan, set it up well before you go on the market, and confirm the lender's rules in writing.
What is a rent-back and will a buyer really agree to one?
A rent-back, or use and occupancy agreement, lets you stay in the home for an agreed period after closing on the sale. Buyers agree to short ones regularly, especially in competitive situations where it helps them win. The daily rate, the end date, insurance, liability, and what happens if you hold over all need to be documented and reviewed by your attorney. Some loan programs and lenders also impose occupancy timing requirements on the buyer, which can cap how long they are able to offer.
Will a sale contingency really kill my offer?
In the competitive towns and price bands, it makes your offer far less competitive than a clean one. In slower segments it is much more workable, and Massachusetts offers to purchase routinely carry contingencies of various kinds. The right question is not whether contingencies are accepted in general, but whether they are being accepted on the specific homes you want, which your agent can tell you from recent activity.
What if my home does not sell after I have already bought?
This is exactly why the cash reserve question comes first. Plan for carrying both properties longer than you expect, and know in advance what you would do, whether that is renting the old home out, dropping the price decisively, or drawing on a bridge facility you arranged ahead of time. Deciding under pressure is how people lose money on an otherwise good move.
