If you’re thinking about selling your condo on East Broadway or a single-family on the West Side, one of the first questions you’re probably asking is: How much will it actually cost me to sell?

As a Realtor in South Boston MA, I’ve found that many sellers focus on their list price but underestimate their closing costs. That can lead to surprises at the closing table—and unnecessary stress.

In this guide, I’ll break down exactly what you can expect to pay in closing costs when selling in South Boston (Southie), updated for 2026. I’ll also share real examples from recent transactions so you can walk into your sale prepared and confident.

What Are Typical Seller Closing Costs in South Boston?

As of Q1 2026, most South Boston sellers pay between 5% and 7% of the final sale price in total closing costs.

For example:

• $800,000 condo → $40,000–$56,000 in total selling costs

• $1,200,000 single-family → $60,000–$84,000 in total selling costs

Here’s what that usually includes:

• Real estate commission

• Massachusetts transfer tax (deed excise tax)

• Attorney fees

• Smoke/carbon certificate

• Title V (if applicable)

• HOA documents (for condos)

• Recording and miscellaneous fees

In my experience as a Realtor in Southie, the exact number depends heavily on property type (condo vs. single-family), price point, and negotiation terms.

---

1. Real Estate Commission (Largest Expense)

For most sellers, the biggest closing cost is the commission paid to the listing brokerage and buyer’s agent.

Typically:

• 4%–6% of the sale price

• Negotiated before listing

If you’re working with the Best Realtor in South Boston, you’re not just paying for a sign in the yard. You’re investing in:

• Professional photography and video

• Digital marketing targeting South Boston buyers

• Open house strategy

• Negotiation expertise

• Pricing accuracy based on micro-markets

I’m seeing major differences between East Side brownstone condos near L Street and newer construction units along West Broadway. Strategic marketing directly impacts your final sale price—and your net proceeds.

---

2. Massachusetts Transfer Tax (Deed Excise)

Massachusetts charges a transfer tax of:

$4.56 per $1,000 of the sale price

Example:

• $900,000 sale = $4,104 transfer tax

• $1,100,000 sale = $5,016 transfer tax

This is automatically calculated at closing and paid by the seller in most South Boston transactions.

It’s a straightforward fee, but it often surprises sellers who haven’t factored it in early.

---

3. Attorney Fees in South Boston Closings

Massachusetts is an attorney state, meaning you’ll need a closing attorney.

Typical seller attorney fees range from:

• $800–$1,500

For condo sales in buildings on East Broadway or Dorchester Street, the attorney often reviews:

• HOA documents

• Master insurance policy

• 6D certificate

• Buyer requests or contingencies

As a Realtor in South Boston, I work closely with experienced local closing attorneys to ensure there are no last-minute issues.

---

4. HOA & Condo-Related Fees (Very Common in Southie)

If you’re selling a condo—which is common in South Boston—there are additional costs.

You may need to pay for:

• 6D certificate (usually $100–$300)

• HOA document package ($200–$500)

• Move-out fees (varies by association)

Newer buildings along West Broadway or near the Seaport edge often charge higher document preparation fees.

In my experience, sellers in three-unit self-managed buildings on the East Side often have fewer fees—but paperwork still matters.

---

5. Smoke & Carbon Monoxide Certificate

The City of Boston requires a smoke and carbon monoxide inspection before closing.

Typical cost:

• $50–$150

You’ll schedule this with the Boston Fire Department before closing.

It’s small—but mandatory.

---

6. Outstanding Property Taxes & Utility Adjustments

At closing, you’ll also settle:

• Prorated property taxes

• Water and sewer adjustments

• Outstanding municipal bills

These aren’t “extra” costs, but they are accounted for on your settlement statement.

If you’re selling mid-year, you’ll pay your share of taxes through the closing date.

---

7. Mortgage Payoff & Prepayment (If Applicable)

If you still have a mortgage, your lender will issue a payoff statement.

This includes:

• Remaining principal balance

• Accrued interest

• Possible prepayment penalty (rare but check your loan)

As the Best Realtor in South Boston MA, I always recommend requesting your payoff early so there are no surprises.

How South Boston Micro-Markets Affect Your Net Proceeds

Not all Southie properties are equal.

I’m seeing:

• East Side family homes commanding premium pricing due to limited inventory

• West Side condos competing more heavily with newer construction

• Properties near Carson Beach attracting strong summer demand

• Units near Andrew Square appealing to first-time buyers

As a Realtor in Southie for over a decade, having sold hundreds of homes locally, I price based on hyperlocal data—not just city-wide averages.

That’s how we protect your bottom line.

If you're unsure what your home might sell for, you can start with a South Boston home value estimate to calculate realistic net proceeds.

How to Reduce Your Closing Costs

While some costs are fixed, you can reduce expenses by:

• Pricing correctly from day one

• Negotiating commission strategically

• Reviewing HOA documents early

• Resolving inspection items proactively

• Working with an experienced Realtor in South Boston MA

Overpricing and reducing later often costs sellers more than they realize.
