Key Takeaways
•The direct answer: Base your strategy on how competitive the house you want is. For well-priced, competitive houses, plan to drop the condo-sale contingency. For slower listings, a contingency may still work.
•The gap: Per MLS PIN figures from mid-2025, Cambridge condos had 3.2 months of supply, while single-family homes had 2.7 months.
•The new rule: For sales after October 15, 2025, Massachusetts sellers can no longer require buyers to waive inspections (per Mass.gov/EOHLC).
•The bottom line: Pick a default rung (contingency, bridge loan, or sell first) before you tour. Then adjust for each house's days on market (how long a home has been listed for sale) and its competition.
Why Is My Condo Sale the Weak Link in My House Offer?
If you own a Cambridge condo and want to buy a house, you're selling into a looser market while buying into a tighter one.
Months of supply measures how long it would take to sell every current listing at the existing pace. Cambridge houses move faster relative to supply than condos do, which hands house sellers real leverage.
The gap between the two markets is only half a month, and both favor sellers. But when a house seller is weighing two similar offers, they're comparing risk, not just price. That small scarcity edge is enough to make your condo sale the first thing they question. A seller may take a lower offer with no condo contingency over a higher one riding on your condo closing.
Inspection rules just made that risk heavier. Under Mass.gov and the Executive Office of Housing and Livable Communities, sales closing after October 15, 2025 can't require buyers to waive an inspection — and sellers can't accept an offer where they were told in advance the buyer would waive one. You can still skip your own inspection if you choose. But waivers no longer work as a bargaining chip, which puts more pressure on your condo contingency to carry the offer.
What Are My Three Options for Structuring the Offer?
Think of this as a ladder. Higher rungs make your offer look stronger — they don't eliminate risk, they shift it onto you.
Rung 1: Use a home sale contingency.
This clause lets you walk away from the house if your condo doesn't sell. It protects you from carrying two homes, but it weakens your offer. Sellers may reject it outright, or add a kick-out clause that lets them keep marketing the house and force your hand later.
Rung 2: Buy first with a bridge loan or HELOC.
A bridge loan is short-term borrowing against your condo equity — expect rates well above a standard mortgage, plus origination fees.
A HELOC often costs less, but only if you plan ahead. Open it before listing your condo, since some lenders freeze access once a sale is underway.
Lenders typically want you qualifying while carrying the condo mortgage, the new mortgage, and the bridge payment simultaneously. That comes down to your debt-to-income ratio and how solid your reserves are.
Rung 3: Sell first, then rent or negotiate a rent-back.
This is the strongest buying position — no contingency, no double mortgage. A rent-back lets you stay in your sold condo briefly after closing. The tradeoff: two moves, temporary housing, and the risk that your dream house shows up before you're ready to buy.
Which Rung Fits the Cambridge House I Want?
Houses drawing several interested buyers — strong curb appeal, a walkable location — call for Rung 2 or Rung 3.
Rung 1 fits listings that have sat a while, carry known issues, or belong to sellers with limited options.
Your own condo matters too: its size, price range, and building type. If condos like yours sell slowly, you'd be holding a bridge loan longer, which pushes you toward selling first.
Keep the contingency if you can't qualify for two homes or your reserves are thin. One caution: don't price your condo off its assessed value. Price it on what buyers are actually paying — that number determines whether dropping the contingency is realistic.
What Are the Strongest Arguments Against This Approach?
"Sale contingencies don't work on Cambridge houses."
Not always true. Per MLS PIN, Cambridge listings have averaged 44 days on market since September 2025 — that's houses and condos combined. A contingency can still work on a house that's sat well past that mark, or when there's no competing offer. Compare against that specific house's days on market, not a house-only benchmark.
"A bridge loan can cost more than it helps."
It can, especially if your condo sells slowly. Interest and fees stack up fast, and extension fees often follow. Start with the 44-day average, then check days on market for condos like yours specifically. Add the usual weeks to closing, since days on market isn't the same as time to closing — then build in a buffer. If condos like yours move slowly, Rung 3 beats Rung 2. Get written bridge-loan quotes from Massachusetts lenders that spell out rate, fees, and extension costs.
"The inspection law levels the field."
It only levels inspection pressure. Sellers can no longer push you to waive your inspection, which means the sale contingency is one of the few terms left that separates offers. Dropping it now carries more weight than it used to.
How Should I Sequence My Move?
Start before you tour houses.
•Check your equity.
•Open any HELOC before listing.
•Get a bridge quote with total costs, including extension fees.
•Repair, declutter, and stage your condo early.
•Use 3.2 months of condo supply as a starting point, then adjust for how fast condos like yours are selling.
•Build a timeline buffer beyond the average days on market.
•Keep your inspection rights in every offer.
In Cambridge, the structure of your offer often wins the house — not price alone. Set your default rung early, then adjust for each listing. Want to see which rung fits your condo and target house price? Ask for a custom sell-then-buy plan before you start touring.
