1031 Exchange Basics for Massachusetts Investors

A 1031 exchange lets you sell an investment property and roll the proceeds into another one without paying capital gains tax at the time of sale. It is a deferral, not forgiveness, and it runs on two hard deadlines that the IRS does not extend: 45 days to identify your replacement property in writing, and 180 days to close on it. Miss either one and the exchange fails, leaving you with a taxable sale you did not plan for.

For investors in Lawrence, Lowell, Haverhill, and Methuen, this is most often the mechanism for trading a single property into a larger multi-family building. Here is how it actually works, and where we see it go wrong.

What a 1031 exchange actually defers

Section 1031 of the tax code applies to real property held for investment or for productive use in a trade or business. When you exchange one qualifying property for another, the gain is deferred rather than recognized.

Two things worth being precise about:

• It defers more than capital gains. Depreciation recapture, which can be a substantial part of the bill on a property you have held for years, is deferred as well.
• It is not a loophole that erases tax. Your basis carries over into the replacement property. If you eventually sell without exchanging again, the deferred gain comes due.

What does not qualify: your primary residence, a property you bought mainly to flip, and property held outside the United States. The "held for investment" test is about your intent and how you treated the property, not a checkbox.

As of 2026, Section 1031 remains available for qualifying real property under current federal law. Nothing has changed the core rules this year.

The two deadlines: 45 days and 180 days

Both clocks start the day your sale closes, and they run at the same time. They are calendar days, not business days. Weekends, holidays, a financing delay, or a failed inspection on the replacement property do not extend them.

Day 45: identification. You must deliver a written identification of your replacement property or properties to your qualified intermediary. The identification has to be specific: a street address, legal description, or other unambiguous designation. "A three family in Lawrence" does not count.

Day 180: closing. You must have acquired the replacement property. There is one trap here that surprises people: if your federal tax return for the year of the sale is due before day 180 and you have not filed an extension, your exchange effectively ends at that earlier due date. Filing an extension preserves the full 180 days.

The practical consequence of a 45-day window in this market is that you should be shopping before you sell. Homes across the Merrimack Valley are going under agreement in about three weeks at the median. Starting your search on day one of a 45-day clock, in a market moving that fast, is how investors end up identifying a property they do not really want.

Why you cannot touch the money

This is the rule that quietly voids more exchanges than the deadlines do.

A qualified intermediary must hold the sale proceeds between the two closings. If the funds pass through your hands, or into an account you control, even briefly, you have taken constructive receipt and the exchange is dead. There is no repair for this after the fact.

Which means the sequencing matters:

1. Engage a qualified intermediary before your sale closes. Not after.
2. The exchange agreement has to be in place at closing so proceeds are wired directly to the intermediary.
3. Your closing attorney needs to know an exchange is happening, in advance.

A qualified intermediary is not the same as your attorney or your accountant, and there are disqualification rules about using someone who has been your agent. Choose one with real 1031 volume and ask how client funds are held and insured.

Why two to four unit multi-family fits the Merrimack Valley

The Valley has a deep stock of two and three family properties, and that is genuinely unusual compared with much of eastern Massachusetts. It is why so many local exchanges land here.

Recent multi-family activity, based on MLS PIN closed sales over roughly the last six months through early August 2026:

• Lawrence: median sale $850,000, 22 days on market, 47 sales, 102.9% of asking
• Haverhill: median sale $762,500, 22 days on market, 50 sales, 102.2% of asking
• Methuen: median sale $830,000, 21 days on market, 17 sales, 101.5% of asking
• Lowell: median sale $725,000, 23 days on market, 73 sales, 100.0% of asking

One number there is worth sitting with. In Lawrence, the median multi-family sale ($850,000) is well above the median single-family sale ($498,000) over a comparable period. Income-producing property is priced on what it produces, not on square footage, which is precisely why it behaves differently as an asset.

Inventory is the constraint. Lowell had 40 active multi-family listings at the time of this pull, Lawrence 19, Haverhill 17, and Methuen just 2. If your exchange depends on finding a three family in Methuen inside 45 days, understand what you are betting on before you sell.

Financing is the other practical advantage: two to four unit properties are generally financed as residential rather than commercial, which usually means better terms and a simpler process than a larger apartment building.

How to underwrite the replacement property

An exchange creates a deadline, and deadlines produce bad purchases. Do the same analysis you would do with no clock running.

• Cap rate. Net operating income divided by purchase price. Use real operating expenses, not a seller's optimistic pro forma.
• Cash-on-cash return. Annual pre-tax cash flow divided by the cash you actually put in. This is the number that reflects your financing.
• The rent roll, honestly. Are the rents actual or projected? Are leases current, and what do they say? Below-market rents are an opportunity only if you can realistically move them.
• Vacancy and turnover. Underwrite for units sitting empty between tenants and for turnover costs. A pro forma at 100% occupancy is fiction.
• Deferred maintenance. Roofs, heating systems, electrical, and knob-and-tube wiring are the usual finds in older Valley multi-family stock. Get real quotes during due diligence, not estimates after closing.
• Debt service coverage. What the lender will look at, and a useful sanity check on whether the building carries itself.

How exchanges actually fail

The failure modes are boringly consistent:

1. Nobody engaged a qualified intermediary before closing. Fatal, and unfixable.
2. The 45-day identification was vague or late. The rules on form and timing are strict.
3. The investor started shopping after selling. Forty-five days is not long in a market clearing in about three weeks.
4. No tax extension was filed, so the 180 days quietly became less.
5. The replacement property was bought to beat a deadline rather than because it underwrote well. This one is not a tax failure. It is just a bad investment that a deadline produced.

Frequently asked questions

Can I do a 1031 exchange on a property I currently live in?

Not on a primary residence. Section 1031 applies to property held for investment or business use. There are situations involving a property that was previously a rental, or a multi-family where you occupy one unit and rent the others, where part of the transaction may qualify. Those are fact-specific and need your CPA.

What happens if I cannot find a replacement property in 45 days?

The exchange fails and the sale becomes taxable in the year it closed. This is the single strongest argument for lining up candidates before you list. Identification rules do allow you to name more than one replacement property within limits, which is a common way to build in a backup.

Do I have to buy something more expensive?

To defer the entire gain, you generally need to acquire property of equal or greater value and reinvest all of the net proceeds. If you buy cheaper or take cash out, that difference, known as boot, is generally taxable. A partial exchange is possible; it just is not fully tax-deferred.

Can I exchange one property for several?

Yes, subject to the identification limits, and it is a common way to diversify. Investors also go the other direction, consolidating several smaller properties into one larger building to reduce management overhead.

Does Massachusetts follow the federal rules?

State treatment is a question for your accountant, and it is exactly the kind of detail that is worth a professional opinion before you commit rather than after. Do not assume state and federal treatment are identical.

Talk it through before you list, not after

The most useful thing we do for exchange clients is timing. Knowing what is realistically available in Lawrence, Haverhill, Lowell, and Methuen, and how fast it is moving, tells you whether your 45 days is comfortable or reckless. That conversation belongs before your sale goes live.
