7 Boston Condo Association Red Flags Every Buyer Should Spot Before Signing the P&S

Most Boston condo buyers spend three weekends touring units and ten minutes reviewing the association documents. That ratio is backwards, and it costs people six figures every year.

Here's why: in Boston — especially in Beacon Hill, Back Bay, South End, Fenway, and Mission Hill, where so much of the inventory lives in historic brick and brownstone buildings — you're not just buying a unit. You're buying a slice of a small business. That business has a budget, a building, lawsuits maybe, an insurance policy, a reserve fund, and a board of volunteers running it. If the business is broken, your unit is worth less and your monthly carry is going to get expensive in ways your mortgage statement won't predict.

This is the checklist I run with every buyer. Use it before you sign a P&S — not after.

Red Flag #1: A Reserve Fund That Wouldn't Cover the Next Roof

The reserve fund is the association's savings account for major capital work. Roofs, masonry, elevators, windows, façade pointing, boilers — all the line items that come due every 15–40 years and cost six figures.

What to look for:

• Reserves equal to only a few months of operating costs is a serious warning sign. Healthy associations target reserves aligned to a current reserve study with replacement timelines.
• Ask for the reserve study by name. If there isn't one — or it's older than five years — that itself is a flag, particularly in pre-1950 buildings.
• Check what's on the horizon. A 1920s Back Bay brownstone with a 22-year-old rubber roof and no reserves is a special assessment waiting to happen.

What "good" looks like: A reserve study within the last 3–5 years, reserves sized to the next major component replacement, and an annual reserve contribution baked into the operating budget.

Red Flag #2: A Pattern of Special Assessments

One special assessment in the past decade? That can be normal — life happens, especially with older Boston buildings facing façade or window cycles.

Repeated special assessments year after year? That's structural underfunding.

Pull the meeting minutes and budgets for the last 24 months minimum. Look for:

• How many special assessments have been levied in the past 5 years
• What they funded (emergency repairs vs. planned capital work)
• Whether they were paid lump-sum or financed by the association
• Any proposed assessment that hasn't yet been formally voted

That last point is the killer. A special assessment that's been discussed but not yet voted may not appear on your 6(d) certificate — even though it could land on your statement six months after closing. The minutes will tell you what's coming. Read them.

Red Flag #3: Owner Delinquency Above 5–10%

Massachusetts law (M.G.L. c. 183A) gives associations the power to lien delinquent units, but it doesn't make the cash flow problem go away in the meantime. When more than 5%–10% of owners are behind on dues:

• The association is operating under stress
• Your lender may flag the project under Fannie Mae or FHA guidelines
• The risk of a special assessment to plug the operating gap rises sharply

Where to find this: the budget, the 6(d) certificate, and — most reliably — directly asking the property manager or treasurer how many units are 30, 60, and 90+ days past due.

Red Flag #4: A 6(d) Certificate That's Not Clean (or Won't Come Quickly)

This is the document Massachusetts buyers and lenders cannot close without. The 6(d) certificate — authorized under Section 6(d) of the Massachusetts Condominium Act — is a statement from the association confirming whether your specific unit owes any common expenses, special assessments, fines, or related charges.

The red flags hiding in the 6(d):

1. The seller is in arrears. Outstanding common charges or fines mean an association lien is possible. These typically get paid from sale proceeds at closing — but you need to know upfront so the math works.
2. A recent special assessment has been levied. It will show on the certificate. Negotiate who pays it.
3. Pending litigation involving the unit or association. This can stop your loan dead. Some lenders refuse to fund projects with material litigation.
4. Errors on the certificate. Yes, this happens. Errors trigger corrections, which trigger delays.
5. The association won't issue it in a reasonable window. Routine processing should take 7–21 business days. Smaller volunteer-run buildings (very common in Beacon Hill) can take up to 4 weeks. Plan ahead.

Pro tip: Order the 6(d) within 48–72 hours of signing the P&S, especially for historic Boston buildings with small boards. Lenders typically want a certificate dated within 30 days of closing.

Red Flag #5: Pending or Active Litigation

Litigation can drain reserves, trigger assessments, and disrupt financing simultaneously. The places it hides:

• The 6(d) certificate (some associations disclose, some don't)
• The board meeting minutes
• The insurance certificate (claims history can suggest litigation exposure)

Most dangerous types:

• Construction defect lawsuits in newer conversions (especially older office-to-residential conversions)
• Developer disputes in buildings under 10 years old
• Insurance carrier litigation
• Owner-vs-association cases over rule enforcement

Ask the seller's agent directly, in writing: "Is the association party to any pending or threatened litigation?" If the answer is anything other than a clean "no," dig deeper before you remove contingencies.

Red Flag #6: Owner-Occupancy Below ~50%

Loan programs care about this. Fannie Mae, Freddie Mac, FHA, and VA all have project-level eligibility rules that look at the ratio of owner-occupants to investors/renters.

In a heavily-rented building:

• Your financing options narrow (especially for FHA and VA)
• Resale liquidity narrows (your future buyer will face the same financing constraints)
• Building "feel" and capital improvement votes can skew toward absentee owners minimizing spend

This matters especially in Boston neighborhoods near universities and medical centers — Fenway, Mission Hill, the Longwood medical area — where investor concentration runs high. Not a deal-killer, but it has to inform your offer price and your financing path.

Red Flag #7: An Insurance Policy That Doesn't Match the Building

Premiums on older Boston condo buildings have risen significantly over the past few years. Two things to inspect:

1. The master policy deductible. A $50,000+ deductible on an older masonry building is no longer unusual — but it shifts substantial risk back to unit owners. Confirm what your HO-6 (individual unit) policy needs to cover to fill the gap.
2. Coverage limits relative to replacement cost. If the master policy was last underwritten when construction costs were 40% lower, you have a real underinsurance problem hiding in plain sight.

Ask for the master policy declarations page and read it. Five minutes of work that has saved buyers from disaster more times than I can count.

The 30-Minute Document Review Every Buyer Should Do

Before your attorney does the deep review, scan these documents yourself in this order:

1. Master deed and bylaws — what can you renovate? What are the rental restrictions? What's the percentage interest?
2. Current year operating budget — does it balance? What's the reserve contribution line?
3. Last 2–3 years of financials — trend on reserves, trend on delinquencies
4. Reserve study — does it exist? When was it done? What's coming due?
5. Board meeting minutes, last 24 months — what's actually been discussed? Lawsuits, assessments, capital projects, owner complaints
6. 6(d) certificate — clean? Special assessments? Litigation noted?
7. Master insurance declarations page — deductibles, limits, claims history

If something on this list feels missing or evasive, that itself is the red flag.

Frequently Asked Questions

What is a 6(d) certificate in Massachusetts?

A 6(d) certificate is a statement from a condominium association — authorized under Section 6(d) of the Massachusetts Condominium Act (M.G.L. c. 183A) — that confirms whether a specific unit owes any common expenses, special assessments, fines, or fees as of a specific date. Lenders and title companies require a clean 6(d) before closing.

How much does a 6(d) certificate cost in Boston?

Associations typically charge $150–$500 for a standard 6(d) certificate, with higher fees for rush service or extra document packages. Cost varies by management company.

How long does a 6(d) certificate take?

Routine processing usually takes 7–21 business days. Rush options (48–72 hours) are sometimes available. Plan 2–4 weeks for small, self-managed Boston buildings — common in Beacon Hill, the South End, and Mission Hill — where volunteer boards may need to meet to authorize issuance.

What is a healthy reserve fund for a Boston condo association?

There's no single statutory target. The right answer is reserves sized to a current reserve study with realistic replacement timelines for the building's major components. A building with reserves equal to a few months of operating costs is undercapitalized regardless of its size.

What happens to a special assessment when I buy a Boston condo?

If an assessment has been formally voted and levied before closing, it typically appears on the 6(d) certificate and is paid by the seller at closing (or negotiated). If it's been discussed but not yet voted, you may inherit it. The meeting minutes are where this distinction lives.

Can I waive the condo document review contingency?

You can, but in 2026's Boston market — especially in older neighborhoods — that's a real risk transfer. A better path is keeping a short, sharp contingency (5–7 days), having documents pre-ordered, and using a buyer's attorney who can turn the review around fast.

Buying a condo in Boston in 2026? The unit matters. The association matters more. Before you sign the P&S on a Beacon Hill walk-up, a Back Bay brownstone conversion, a South End loft, or a Fenway high-rise, let's review the building's documents together. Spotting these red flags early is the difference between buying a great home and buying somebody else's deferred maintenance.
