Key Takeaways
•The short answer: In the Boston real estate market, condos are lagging single-family homes because far more condos are for sale relative to buyers. MLS PIN data shows 11.0 months of condo supply in July 2026, compared with 5.7 months for single-family homes.
•Prices are still rising, just more slowly: Greater Boston condo median prices rose 3.7% year over year, versus 6.6% for single-family homes. The median is the middle sale price. Condos are underperforming houses, not falling in value.
•A likely factor: Small condo landlords face rising HOA dues (monthly fees paid to the condo association), special assessments (one-time charges for big repairs), and the Massachusetts broker fee law. Those costs give some landlords reasons to sell, which can add to an already high condo supply.
•Single-family is different: Houses sell faster, and most single-family owners don't pay condo association dues or assessments.
•The bottom line: If your rented condo barely breaks even or loses money, run your numbers now. Listing this fall or winter may beat competing with more sellers in spring.
Should Boston Condo Landlords Rent Again or Sell This Fall?
It's mid-October in Boston. September leases are signed, and some small landlords are still staring at empty condos.
If that's you, the question is simple: re-list it for rent, or sell it?
Here's my take: the ownership math for condo landlords has shifted. Landlord-paid broker fees, climbing HOA dues, and possible special assessments are all landing at once. That combination is pushing some landlords toward the exit, which only adds to the inventory buyers have to choose from.
That's the likely story behind condos lagging single-family homes across Boston. The supply gap is the measured fact. Rising costs are the probable explanation.
This isn't a blanket call to sell — it's a call to check your numbers.
Why Are Boston Condos Weaker Than Single-Family Homes?
Start with supply.
"Months of supply" measures how long it would take to sell every listed home at the current pace of buyer activity.
MLS PIN shows Boston condos carrying 11.0 months of supply in July 2026, versus 5.7 months for single-family homes. For a condo seller, that means buyers have more options — and usually more leverage at the negotiating table.

Condos are also sitting longer. The same MLS PIN snapshot shows a median 45 days to sell, compared with 34 days for houses. Those extra 11 days translate into more HOA dues, taxes, insurance, and mortgage payments coming straight out of your pocket.
Pricing tells a similar story. In Greater Boston, single-family new listings jumped 31.3% in August year-over-year — and the median price still climbed 6.6%. The condo median, meanwhile, rose just 3.7%.

More houses hit the market and prices still climbed. That's solid demand. Condos gained less, which points to softer demand on that side. Rising single-family supply could narrow the gap eventually, but for now, houses hold the advantage.
How Did the Broker Fee Law Change a Landlord's Math?
The broker fee law made tenant turnover considerably more expensive for small landlords.
Under the Massachusetts law that took effect August 1, 2025, whoever hires the broker pays the fee. Hire an agent to find a tenant, and that cost is yours — according to NBC Boston, often equal to one month's rent. The median two-bedroom asking rent in Greater Boston was $3,250 in September.

Apply your own asking rent, and one turnover can cost roughly a month of income — before you even factor in vacancy.
You generally can't recoup that upfront. Law firm Davis Malm notes Massachusetts caps upfront charges at first month's rent, last month's rent, a security deposit, and the cost of a new lock and key.
NBC Boston reports hundreds of complaints to the Attorney General's office, and under the state's Consumer Protection Act (Chapter 93A), tenants can recover up to three times an illegal fee, plus attorney's fees.
Now stack it all together:
•Vacancy
•A broker commission
•Higher HOA dues
•Possible special assessments
•Underfunded reserves (the association's savings for future repairs)
That's a lot for one rental condo to absorb. Most single-family owners skip the HOA dues and assessments entirely, giving them more breathing room. The broker commission may be deductible as a rental expense — worth confirming with your accountant — but it won't erase the hit.
What Are the Strongest Arguments Against Selling?
Fair reasons exist to hold. Test each against your actual numbers.
Can landlords just build the broker fee into rent?
Sometimes — but only where demand allows it. Renters who are already stretched can't easily absorb fee-driven increases. In neighboring Brookline, the town's own housing analysis found over 45% of renters spend more than half their income on rent.
Over a multi-year lease, rent growth may claw back part of the fee. Keep long-term tenants, and it matters less. Frequent turnover makes it a recurring cost.
Does selling while rates are elevated mean taking a lower price?
Possibly. On an $800,000 loan, the monthly payment at 6.30% runs $387 lower than at 7.03%, before taxes and insurance.

That's a real argument for waiting — higher rates shrink buyer budgets, and some buyers pause entirely. But "wait for a recovery" assumes condos are in a slump. They're not. Prices are still up 3.7% year over year. The weak spot is supply — 11.0 months for condos versus 5.7 for houses — and nothing suggests that gap is closing.
Waiting carries its own monthly price tag: HOA dues, taxes, insurance, and any vacancy costs keep accruing, with no guarantee rates or supply improve. Weigh those costs against whatever price gain you're banking on. And listing earlier puts your unit in front of buyers before more landlords potentially crowd the market.
The right call depends on your building's reserves, your mortgage rate, your tenant situation, and your monthly cash flow.
Is enforcement weak enough that the fee law doesn't matter?
Uneven enforcement may let some landlords dodge the cost for now, which does blunt the law's short-term bite. But Davis Malm reports a pending bill, S.224, that would treat violations as consumer protection breaches, with fines up to $1,000 each. Combined with tenants' existing Chapter 93A claims, skirting the rule looks more like a legal risk than a business plan.
Should You Sell Now or Hold Your Boston Condo?
My practical advice: if the numbers no longer work, consider listing this fall or winter, ahead of other landlords who may list later.
Run through this checklist first:
1. Run your real numbers. Calculate yearly net cash flow after HOA dues, expected assessments, vacancy, and one broker fee per tenant turnover.
2. Ask your association for documents. Request the reserve study, which checks whether savings for future repairs are adequate. Also ask about current reserve funding and any planned assessments or dues increases.
3. Study your block, not just the headlines. Your building, street, and neighborhood matter more than citywide averages. Get a price estimate based on recent sales of similar units — your tax assessment isn't what a buyer will actually pay. A well-kept unit near transit and shops may sell above the condo average.
4. Plan around the lease. Selling with a tenant in place may attract investors; selling vacant may attract owner-occupants.
Who should hold? You're likely in good shape with a low-rate mortgage, steady positive cash flow, reliable long-term tenants, and a well-funded association.
If the unit is losing money, the market is sending a message. Condo values are still rising, just more slowly than houses, and condo buyers have more choices than ever. Owners whose condos lose money have good reason to consider selling. Single-family owners generally have more room to wait.
Don't bank on a vague "spring market" plan. Run your numbers now — and to see current supply, pricing, and buyer demand for your specific Boston neighborhood or building, reach out for a condo-by-condo market review.
