1031 Exchange Broker in Brooklyn: Sell Your Investment Property and Plan Your Replacement

555 Properties LLC sells your Brooklyn investment property and helps you find replacement property, working alongside your qualified intermediary, accountant and attorney.

A Section 1031 exchange lets investors sell real property held for business or investment and reinvest in other like-kind real property while deferring capital gains tax. For Brooklyn owners of rentals, mixed-use buildings and development sites, it can be a powerful planning tool. It also runs on strict deadlines, so the sale of your current property and the search for your next one need to be coordinated from the start. That coordination is where a broker who understands the process helps most.

Who Does What in a 1031 Exchange

1031 exchange team: real estate broker, qualified intermediary, accountant or tax attorney, real estate attorney
The professionals involved in a typical 1031 exchange.
  • Real estate broker (555 Properties LLC). Prices, markets and sells your relinquished property; helps you find and evaluate replacement property; keeps both transactions on schedule.
  • Qualified intermediary. Holds the sale proceeds so you never take control of them, and prepares the exchange documents. Engage one before your sale closes.
  • Accountant or tax attorney. Advises on whether an exchange fits your goals, how much tax could be deferred and how to report it.
  • Real estate attorney. Negotiates contracts for both the sale and the purchase, including language that supports the exchange.

The Timeline

BeforeEngage a qualified intermediary and advisors. Line up potential replacement properties.
Day 0Your sale closes. The intermediary holds the proceeds.
Day 45Identify replacement property in writing.
Day 180Close on replacement property, or by your tax return due date if earlier.

Identification Rules

Within the 45-day window, replacement property is generally identified under one of three rules:

1031 identification rules: three-property rule, 200 percent rule, 95 percent exception
The three common identification rules.
  • Three-property rule: identify up to three properties of any value.
  • 200% rule: identify any number of properties whose total value does not exceed twice the value of the property sold.
  • 95% exception: identify more, but acquire at least 95% of the total value identified.

Your qualified intermediary and tax advisor will confirm which rule fits your plan. For the details, see the IRS instructions for Form 8824.

Common Pitfalls to Avoid

  • Touching the money. Receiving the proceeds yourself, even briefly, can end the exchange.
  • Missing deadlines. The 45 and 180 day periods generally cannot be extended for ordinary delays.
  • Boot. Cash left over, or a reduction in mortgage debt, can be taxable.
  • Related parties. Exchanges with family members or related entities have special rules.
  • Primary residences. A home you live in does not qualify.
Investor takeaway: Plan the purchase before you sign the sale. Your contract dates, your replacement search and your advisors all need to be aligned on day one.

1031 Exchange FAQ

Is Valerie Sebbag a qualified intermediary?

No. A 1031 exchange requires a qualified intermediary to hold the sale proceeds. 555 Properties LLC acts as the real estate broker: we market and sell your relinquished property and help you find replacement property. Your qualified intermediary, accountant and attorney handle the exchange documents and tax advice.

How long do I have to complete a 1031 exchange?

Generally, you must identify replacement property within 45 days of selling and complete the purchase within 180 days, or by your tax return due date if that is earlier. These deadlines are strict.

Can I exchange a Brooklyn rental for a different type of property?

For real estate, like-kind is broad. Investment or business real property can generally be exchanged for other investment or business real property, such as a mixed-use building for a multifamily building. Your tax advisor should confirm your situation.

Does my primary residence qualify?

No. A home you live in as your primary residence does not qualify for a 1031 exchange, though other tax rules may apply to its sale.
