Boston Condo Conversions

Boston Condo Conversions

by Stephen McCarthy

One of the great advantages of owning a multi-family property in Boston is the potential to convert it into condominiums.

Experienced investors and developers have been doing this for decades—buying multi-unit buildings, converting them into condos, and selling the individual units to maximize their investment.

But many property owners aren’t full-time investors. They may own just one two-family or three-family building and wonder:
Is a condo conversion possible? And does it make sense for me?

I work with many clients in this exact situation, and here’s what I often share:


Step 1: Understand Your Property’s Value

Before making any decisions, it’s important to know:

  • What is your property worth as-is?
  • What would it be worth renovated?
  • What could it sell for as individual condo units?

Don’t assume a condo conversion will automatically yield the highest sale price.

Note: Single-family homes are not candidates for condo conversion unless they can be legally reclassified into multiple units. That’s a separate discussion.


What Can Be Converted?

You can convert your existing:

  • Two-family into two condos
  • Three-family into three condos
  • And so on...

You do not need to renovate the property to convert it. Many typical Boston multi-families can be converted “as-is.”

Of course, the condition of the property will influence the final sale price of each unit.


What You’ll Need

To complete a condo conversion, you’ll need:

  • An attorney to draft and record the condo documents
  • An architect to create plans, surveys, and necessary documentation

Estimated cost: Around $10,000, though this can vary depending on the property and complexity.


Why Convert?

Owners may choose to convert for various reasons:

  • To retain one unit and sell the others for cash
  • To divide the property among family members
  • To maximize value in a changing market

Whatever the reason, it’s important to consult trusted professionals and plan carefully.


Additional Considerations

  • City taxes on three condos will be higher than on one multi-family.
  • If there’s an existing mortgage, it must be paid off before the building can be legally converted.

I’ve helped many clients successfully convert their multi-family properties into condominiums. If this is something you’re considering, I’d be happy to guide you through the process.
