The process

Three deadlines. Zero surprises.

A 1031 exchange is simple when it's run right — and unforgiving when it isn't.

1

Sell & park

Your proceeds go straight to a qualified intermediary — you never touch the money, or the exchange is void.

2

Identify in 45 days

Name your replacement property within 45 days of closing. The clock is absolute — the IRS doesn't extend it.

3

Close in 180 days

Acquire the replacement within 180 days. Capital gains, deferred — your full equity keeps compounding.

Questions

Frequently asked.

What is a 1031 exchange?
A 1031 exchange (named after IRC Section 1031) lets real estate investors defer capital gains taxes by reinvesting the proceeds from a sold property into a "like-kind" replacement property. Instead of paying 15-30% in taxes at sale, you keep 100% of your equity working for you.
What are the 1031 exchange deadlines?
You have 45 days from closing to identify potential replacement properties, and 180 days total to close on the replacement. These deadlines are strict and cannot be extended.
Can I do a 1031 exchange on my primary residence?
No. Section 1031 only applies to property held for investment or business use. There are strategies involving converting a primary residence to a rental before exchanging.
What is a reverse 1031 exchange?
In a reverse exchange, you acquire the replacement property BEFORE selling your current one — useful in competitive markets. It requires an Exchange Accommodation Titleholder (EAT) to hold the property.
How much does a 1031 exchange cost?
It depends on your exchange. A straightforward forward exchange is the simplest; reverse, construction, and multi-property exchanges involve more structure and work. Whatever the number, the deferred tax almost always dwarfs it — build your free 1031 plan and Leah will give you a straight answer for your situation.
What is a DST 1031 exchange?
A Delaware Statutory Trust (DST) is a pre-packaged investment property that qualifies as like-kind replacement property — popular with investors who want out of active management. These are zero-cash-flow structures: there's no monthly check — the return comes through full tax deferral, debt paydown, and your share of value at exit.
